What are those bugs on your squash? Here are tips on how to identify, control, and get rid of squash bugs in your garden.

What are Squash Bugs?

Squash bugs are the bane of a gardener’s existence! They are very difficult to kill and can cause a lot of havoc. Squash bugs are most commonly found on squash plants (hence the name), but they also often appear on pumpkins. Their damage is limited to the cucurbit family. Other pests that are commonly found on squash include squash vine borers.

Squash bugs are often mistaken for stink bugs, as they are similar in appearance and both have a foul odor when squashed. However, stink bugs are wider and rounder than squash bugs.


How to Identify Squash Bugs

The squash bug is fairly large (over ½-inch long) with a brownish or gray body and flat back. The edges and undersides of the abdomen have orange stripes. They are able to fly, but they often simply walk around on plants. Young squash bugs, or squash bug nymphs, are gray and have black legs. They move quickly and often in groups on the undersides of leaves.

Squash bugs overwinter in your dead leaves, vines, under boards, and even in buildings. They fly to garden plants to mate as soon as vines start forming, and they lay egg masses on the undersides of the leaves. You’ll find adults beneath damaged leaves and near the plant crown.

Squash Bug Damage

These bugs inject a toxin into the plant and suck the sap right out of it with their sharp, sucking mouthparts. This causes yellow spots that eventually turn brown. The leaves will wilt because the damage prevents the flow of nutrients to the leaves, and then they will dry up and turn black, crisp, and brittle. The leaves also sometimes have ragged holes. Smaller plants will die, and squash bug feeding can decimate young fruit.

The wilting can resemble bacterial wilt, which is a disease spread by cucumber beetles (another squash pest), so be sure to find the bugs or eggs and identify them correctly.

Control and Prevention

How to Get Rid of Squash Bugs

  • Early detection is critical! You want to catch squash bugs before they grow into adults or they are very difficult to kill.
  • Pick egg masses off the plants in the morning and later in the day. One reader fills a vase with water and liquid detergent and flicks the squash bugs into the water. Once the bugs are dead, it’s fine to dump the water anywhere. You can also simply scrape the eggs off the leaves with a butter knife and let them fall onto the ground, where beetles will eat them. Eggs hatch in about ten days, so be sure to check for them on at least a weekly basis.
  • Place a board or shingle in the garden at night. During the night, both adults and nymphs will congregate underneath the board. Squash between two hard surfaces in the morning and dispose.
  • Insecticides (such as carbaryl/Sevin) are most effective if applied when eggs are hatching. See your local garden center or cooperative extension service for controls that are locally approved.
  • Keep checking your plants, at least daily. If there are no more than a few vines infected, keep collecting and destroying the bugs and crushing the egg clusters that you find on the undersides of leaves.

How to Prevent Squash Bugs

  • Prevention is key: In the fall, be sure to burn or compost old squash vines to rid your garden of any possible shelters for breeding and over-wintering.
  • Avoid deep, cool mulches like straw or hay that provide an environment that these bugs seem to love.
  • Practice crop rotation.
  • Consider keeping vines covered until blossoming begins. Remove the cover for pollination needs. There is only one generation of squash bugs per year, and you can avoid them by covering your plants for the first month of spring. You can also delay planting your squash until the early months of summer.
  • Companion planting can be useful in repelling squash bugs. Try planting nasturtium and tansy around your plants that are commonly affected by squash bugs.
  • Select varieties of squash that are resistant to the squash bug if you have a big problem. ‘Butternut’, ‘Royal Acorn’, and ‘Sweet Cheese’ varieties are all more resistant to squash bugs.

"Squash bugs" please help!

I've found bugs and eggs on my gourd plants. I'm not sure if they're squash bugs even though the description seems to match the pictures vary slightly. The adults I'm finding are black in the front and back with orange on the outter mid section of the bug. The eggs are mostly under the leaves but not always. There seems to be tons of dark green eggs as well as some lighter cream colored which are almost white. Please help me identify these critters so I can try to get rid of them! I wish I could share a picture here of what I've found! Thank you.

Killing Squash bugs

I do something I have never seen mentioned as a way to kill squash bugs. I spray the plants and ground thoroughly. Then I wait a couple of minutes. The squash bugs begin climbing to the top of the leaves--I assume to get dry. Wearing gloves I simply squash the bugs and lay them out for a "body count." By the time I get to one end of the plants, more bugs have climbed to the top of the other end. I repeat going down the row until there are no more bugs. If I have time, I soak the ground and plants again just to make sure. It worked until I missed a day, then the plants suffered.

Squash Bugs

This is exactly what has been invading my garden the latter part of the summer/early fall. Not only have I seen them in my zucchini plants, but also they invaded my greenhouse and they literally sucked the life out of many of my tomatoes. They appeared to be laying eggs in them. (Yuk!) We have had a garden for a few years now and never had this happen before. We are in Southern Oregon and now that the overnight temperatures have dipped to the low 40s, the bugs are finally gone. I have so many zucchini/squash plants, they were unable to take them over, thankfully.

Squash bugs on 1st and 2nd floor house screens

I have never had this happen before. I am getting what appear to be squash bugs attaching themselves to my first and second floor screens. I have researched every bug and these definitely look like squash bugs with the body shape and color, and not stink bugs. I have been flicking them off the screens and when on a window ledge spray them with hair spray. Has anyone else experienced this, or can tell me why this is occurring. I am from the far northwest side of Chicago.

Squash bugs

We have the same problem here in south central New York. They are trying to find a way into the house to hibernate for the winter. They are very annoying.

Killing adult squash bugs

I have tried EVERY remedy imaginable for killing or repelling (adult) squash bugs, and NONE of them has ever worked. I am convinced that all of the home remedies out there are a waste of time.

Immature squash bugs are easy to kill, but the adult bugs (which are the ones that show up first), are a different story.

Checking each vine daily, and physically removing (and smashing) the bugs and eggs by hand (or duct tape) DOES help, but you never find them all, and this becomes very time-consuming as the plants get larger. And if you ever have to skip checking for a day or two, you are likely to find your plants dead when you return. Picking the bugs off by hand has never been a good solution for me.

Having said that, I HAVE found a way to get plenty of squash. The ONLY thing that has worked for me is to plant 2 or 3 times more squash plants than I really want. Yes, the squash bugs WILL still eventually kill them all, but not all at once. So, if you plant extra plants, AND check for bugs as often as you can, you can probably get all of the squash that you want. For me, that means planting 15 plants or so, instead of the 5 or 6 plants that I REALLY want.

To save space (since I don’t really WANT to plan 15 squash plants!), I plant them between my sweet corn rows, and the squash plants seem to like that just fine. I think they actually do a little better there, than in the full Kansas sun.

For those that are interested, here are the many failed squash bug remedies that I have tried over the years.
• I have tried spraying the plants regularly with Sevin (and every other pesticide).
Sevin and other over-the-counter pesticides are totally ineffective against the adult squash bug. But I still tried. I used liquid spray on top AND undersides of leaves, and generously on the main stalk. I used Sevin dust to cover the ground around the plants. And I have sprayed the bugs directly. Nothing would kill the adult bugs.
• I have tried spraying the bugs with a mixture of dish soap and water.
This did not bother the bugs at all.
• I have tried placing boards around the base of the plants, as I have read that the bugs will hide there, making them easier to find and kill.
I have seen many online sources suggest this, but I have found it to be totally ineffective. A healthy squash plant will get fairly large, and their long vines and large leaves make it very easy for the bugs to hide. I have seen the bugs circle around a stalk to hide as I look around the plant. With mulch around the plants, the bugs can pretty much hide anywhere, and usually NOT under the boards. I even tried NOT using mulch, but that did not help.
• I have heard from MANY sources that marigolds will repel squash bugs.
As far as I can tell, squash bugs are completely unfazed by marigolds. I planted marigolds around the outside of my entire garden, and planted them all around and amongst the squash plants. TOTALLY INEFFECTIVE. I will say that there are many varieties of marigolds, and I have not tried them all. I think this remedy is a waste of your time, unless someone can tell you exactly which type of marigold repels squash bugs (and even then, I would be skeptical). I still have marigolds in my garden just because my family likes them.
• I've been told that using cedar wood chips as a mulch around the plant will repel squash bugs and keep them away.
This was also totally ineffective.
• I have tried tying the squash vines to a wire fence (to get the leaves and vines off of the ground).
Unlike cucumbers and other vining plants, the squash vines are just too heavy and cumbersome for this to work well. I'm not sure it would help even if I COULD get the plants to grow on a fence, or that it would be good for the plant.
• I have tried forcing the plants to grow inside a tomato cage, again to try and keep the leaves and vines off of the ground.
This did make it a little easier for me to find/see the bugs, but I'm not sure it was really healthy for the plant, and I still lost most of my plants before they produced a single squash. I have to declare this solution a total failure as well.
• I have tried crop rotation--planting the squash in a different location in the garden each year.
Totally ineffective against squash bugs (although still a good idea, in general).
• I have tried skipping growing squash for a year.
Squash bugs reappeared as soon as I started planting squash again.
• I have tried REDUCING the number of plants to just a few, so that I could more easily manage checking for bugs on a daily basis.
I just could not catch enough of them soon enough to prevent damage and death of the plants. I sometimes could not check every single day.
• I always remove and burn the dead squash plants immediately when they die.
Still a good idea, even though it has never helped my squash bug problem.

Cover the plants.

What are you suggesting to cover the plants with until the blossoming begins? You say plant the squash till later at the beginning of summer meaning late May or early June! Will that give sufficient time for the squash to mature? I find that once the squash has finished they move to the cucumbers.

Pumpkin deth

Ugh last night I had a beautiful lush pumpkin plant . Went outside to water and it was wilted and dead!???I have other squash and melons that are beautiful close to the dead one that so far unaffected? ? I pulled it up and found some squash bugs and eggs when removing it.could it be possible for the insects to kill it over night? ?????

Pumpkin Vine

Hi William,

It’s not likely that squash bugs would kill your pumpkin plant overnight. However, it could be that the vine had a squash vine borer in it, which would kill it quickly. Go here to read more https://www.almanac.com/pest/squash-vine-borer#comment-80153.


Squash Bug fighting

Found an exciting way to remove squash bugs; connected a narrow tube on to a shop vac with an inch or two of soapy water at the bottom, worked like a charm


I disagree that there is one generation per year of squash bugs. I typically fight them all summer, and even if I kill them and they disappear for a time, they return each time after a few days. They also get on butternut squash.

Getting rid of squash bugd

Yes, most assuredly, squash bugs are "the enemy", but, to my minds eye, so is commercial pesticides (seven and the like). For the last 3 years (this is the 4th) I have been using neem oil on my squash. So far, the bugs are gone and the plants live and produces abundant amounts of produce. I hope this year is no different. I have also used neem on the grapes, cabbage and cauliflower (works fabulously on the worms that invade them), and the little light green afids on the fruits trees. The Neem did not work on the black acids much to my dismay.

Try soil drenching with neem 4tsp/gal works everytime doesnt hurt beneficials

Definate squash bugs inside house

Marjorie, I have both squash bugs and boxelder beetles in my house - ick! My exterminator friend told me that they both find a warm spot in the house when it gets cold outside and in the warmer whether, come out any way they can.......how do they get through into my living room or bedroom??? I have been killing 1-2 of them almost every day for the last month. We have an ancient house and can't possibly find/fix every tiny entry point but we do as much as possible to maintain and restore our home. I think it's just something we have to put up with for a while.

Squash bugs in my hgome

I've been getting squash bugs in my bedroom, mainly, for the past couple of months. They arrive one at a time, 2 or 3 days a week, which I easily kill since they don't move, but I can't get rid of them -- one arrived yesterday after I thought I'd done the job by closing off the floor register, which I assume was how they got in. I don't even have a garden, nor do any of my neighbors so I don't know where they're coming from. What can I do?

Bugs about the house

Hi, Marjorie, We are thinking that the invaders are not squash bugs but may be a lookalike bug called a Boxelder. (We had never heard of it either.) These pests that can wreak havoc on fruit trees and whose main source of food is—can you guess?—the box elder tree, seek warmth in the off season—and that’s why they are coming into your home. (Do you have fruit trees or are they some nearby?? How about box elm? No matter; these critters can fly several blocks.) The general advice is to seal cracks in walls, doors, basement windows, and vents, etc., and make sure that screens are intact. You are on to the right idea about the floor register, but the bugs are getting into your house before you see them in the register. Eliminate leaf and other debris from around the house; that gives the bugs a place to hide. These nasties do not like water, so you can hose them to eliminate them (do this outdoors; this is not recommended indoors). BTW, insecticide sprays are no more effective than the hose and the vacuum, so investing in chemicals is not worth the money.

As noted, while neither you nor your neighbors have gardens, someone (or ones) nearby have some plants that must be attracting and “hosting” these bugs. And it occurs to us: Are your neighbors also being invaded? It doesn’t seem right—morally or naturally—that you should be the sole victim.

We hope this helps!

Your Bugs

Your bugs are probably marmorated stink bugs and not really squash bugs, they look similar,fit the profile you described and aren't really associated with the garden at all.

What bug produces 1000s of

What bug produces 1000s of small black eggs then a green caterpillar emerges.. sfter that they cocoon themselves under my pumpkin leaves and eventually turn dark brown. I killes about 700 of these things by hand already and I just noticed the caterpillars eating my biggest pumpkin that is not even green yet.. damage is minimal but will it survive? So annoyed with these bugs.. thanks guys

What's eating my raspberry plants

Hi, I was reading above and the bug that is munching on my raspberry plants almost looks like a squash bug except it is golden yellow in color. Help me identify this bug please so I can kill it. I live in Wpg.Mb. Canada if that helps. Thank u

bug ID

The adult raspberry fruitworm is a light-brown beetle which munches on leaves and buds; larvae feed on the fruit and buds. However, it is a little late for them to appear–they are usually come out in spring or early summer as adults. Another pest of raspberries is the tarnished plant bug (nymph can be a bright green), although I haven’t heard of a golden type. There are several species of plant bugs similar to squash bugs. Perhaps if you showed a sample to a local garden center, they might be able to identify it for you. Good luck!

I heard this from an older lady who does it every year and wanted to get some additional comments on it. she sprays her plants down with dawn dish soap and water, has anyone tried this? and if so, was it successful?

Soapy Water for Squash Bugs

Hi, Clay! This type of solution has worked for other bugs like aphids, and there is some evidence that it could work for squash bugs. Try spraying with a mild solution of water and a few drops of dish soap. If that doesn’t work, check out some of our other tips above! Good luck!

Oh, how I loathe these bugs! I welcome predators into my garden, too--frogs, toads and praying mantis are all welcome there, as are my Icelandic chickens, who will eat the bugs off the plants.

The soils that I've started

The soils that I've started my seedlings in is covered in mold! And remedies? I've read about the essential oils, but not sure of oil/water ratios.


The presence of molds usually indicates overwatering. If you think the seedlings will survive it, you could try to scrape off the mold. Definitely hold off on watering for a while. And when you do … mist, don’t pour.

Mold sometimes comes from poor/old/unsterile potting soil or unclean pots.

leaf leg bugs

every year i have leaf leg bugs on my pomegranate and they ruin the fruit is their a way to get rid of them with out poison my tree is about 15' and i dont want poison on it please can any body help

leaffooted plant bug on pomegranate

Leaffooted plant bugs especially like to feed on cracked fruit. To control the them on pomegranate, be sure to remove all cracked fruit. Also remove fruit and leaf debris before winter; the bugs will overwinter in them. There are natural parasites, but I don’t know if they are available commercially: Gryon pennsylvanicum (attacks the eggs) and a tachnid fly called Trichopoda pennipes. Handpick pests as you can (wear gloves, because they emit an odor). Remove eggs under leaves. Some gardeners protect their fruit by placing them in a muslin or cotton bag that prevents the bugs from accessing the fruit; this is better in drier climates, however. The bugs also like to overwinter in juniper, cyprus, or eucalyptus. Remove weedy areas, which is where the bugs feed when fruit is not available in winter or spring. Nymphs can be knocked out of the tree by gently shaking the branches; lay a white sheet below to catch them and dispose. Chickens can help control the bugs on the ground hiding in plant debris.

leaf leg bugs

Try spraying with a soapy water mixture of Dawn original and water 2 tsp dawn per 1 quart water on the bugs early morning and evening until gone. Do not spray in the heat of the day as it will tend to burn the leaves of plant. I have not tried on leaf bug but it works on many other bugs. This has been our life saver this year with squash bugs. Good luck!

One of the most common squash pests is the beetle, but this does not sound like that. (The beetle has a triangle-shape “shield” on his back—but no gel. Yes, you know that.)

Wet down leaves

I have had good luck controlling them by wetting down the leaves in the late morning. The squash bugs must not like getting wet because once I am done they run up to the top side of the leaves to dry off. I just pick them off into my cup of soapy water. Doing this allows me to see where the adults are at and then I can find the egg masses on those plants and remove with duct tape.

Great info in this piece. I

Great info in this piece. I too have found early detection and persistence to be key in controlling these bugs. I use a little butane torch on the egg masses and bugs. A small portion of the leaf will be burned but this method seems to work pretty well. I've had some very large and productive squash plants this year despite the presence of the bugs. I learned a lot, and next year will be even better I'm sure.

Very helpful info concerning

Very helpful info concerning the squash beetle. I believe burning all the infected plants at season's end will go along way to get rid of them next year. I do have wood raised beds, so I'll probably always have to do close inspection during squash season.

Thank you again for the solutions.


should i pick squash being

should i pick squash being eaten by squash bugs?

You can harvest mature squash

You can harvest mature squash that has been attacked by squash bugs. The squash should be safe to eat, as long as there are no rotten areas (which you'd want to cut out). If you have used an edible-crop-approved pesticide, be sure to read the label to determine the amount of time you need to wait until it is safe to harvest the crop; wash the squash thoroughly before eating.

I spent a better part of my

I spent a better part of my afternoon ridding my plants of squash bugs and eggs. I dropped the eggs and bugs in a bucket of soapy water. Unfortunately I knocked over the bucket in the garden with all the eggs and dead bugs.... Will the eggs still hatch? Im so mad right now. I lost all my pumpkins and squash plants to the pests last year I am on a mission to save them this year.

The eggs will probably not

The eggs will probably not hatch if they are not attached to a leaf. You can cover the area with cardboard or newspaper mulch or put some black plastic or landscape fabric down to be on the safe side.

I usually find clusters on

I usually find clusters on the underneath sides of the leaves in July. Today I checked my plants, the fruit is growing nicely, not big enough to pick, but I swear I see what looks like an egg here and there on the stems and the squash themselves. Nothing on the leaves though and the 'eggs' I see are not in clusters. Are these eggs??

You can tell by the color.

You can tell by the color. Squash bug eggs are copper colored. We've added a better picture to this page for you. 

I have an Apricot tree that

I have an Apricot tree that produces loads of very sweet apricots, --- but every year we find that most of them have eaten spots about 1/8" to 3/8" in diameter. The first year I built a 10ft cage with 3/4" netting to keep the birds out, we got the same eaten spots. This year I changed the netting to 3/8"and had the same problem. Yesterday my wife found several large gray bugs feasting on the fruit, they look just like your photos of squash bugs. Has anybody out there had the same problem ,And if so have you found a solution? Thanks

Squash bugs are a type of

Squash bugs are a type of "true bug." Although they are not known to attack apricots, there are lookalike true bugs that do, such as various types of stink bugs. They may cause catfacing (corky areas) and deformed fruit. For more information, see:
 For other apricot pests, see:

Why are these bugs in my

Why are these bugs in my house. I find them all the time on tv screen and many different rooms in my house.

Squash bugs and stink bugs

Squash bugs and stink bugs may invade homes in the fall as they look for a warm place to shelter during the winter. They may cluster in attics, walls, etc.
Other lookalikes, such as pine seed bugs, can accidentally come into the home as well during the late summer etc, as they bask in the sun on the south side of buildings.
To deter these bugs, seal up cracks around windows, doors, foundations.

I use duct tape to remove

I use duct tape to remove both bugs and egg clusters. I have had a terrible problem as I've mulched leaves directly into my garden for years. Once I started my morning rounds with duct tape the zucchini started to flourish.

The squash bugs destroyed the

The squash bugs destroyed the squash and zucchini before moving on to my watermelons and killing those vines. So once everything is cleaned up and vines destroyed, will using the soapy water kill any eggs and bugs left at end of season? And can the same thing be repeated before planting crops in the spring?

You did the right thing in

You did the right thing in cleaning up the infected plants but these pests might be back again.  Single (unlated) bugs overwinter under plant debris, then in spring find a mate and start again, leaving eggs on the underside of leaves. A very cold winter could be your relief; they are more likely to survive mild winters.
Neem and horticultural oil and other soap products have been indentified as control agents but good penetration is needed. Consult a local nurseryman for product.
If they show up again, the Colorado extension recommends early season treatment with diatomaceous earth and or pyrethrins, as organic methods.
Next season, consider resistant varieties, rotation to non-cucurbit crops, and/or row covers (these help to keep the bugs from landing on your plants).
Here is further advice, from Utah's coop extenstion (useful in any location): https://extension.usu.edu/file...

Plant dill with your squash -

Plant dill with your squash - or tear some off a plant and put it next to the squash and repeat every week or so. Didn't get any squash til last year - first year I started using the dill. All the plants died the many years before after setting fruit and it getting pretty far along. Now I'm the "squash lady". We give away wheel barrow after wheel barrow of squash - I'm planting much less next year. The dill is pretty much gone by now but the plants are big and healthy (last of August); if they all died now I would consider the year a phenomenal success. I am going to start planting a row of dedicated dill from now on every month or so - buy the dill seed in bulk from the coop ("hippie grocery store").

I'm Having Some Major

I'm Having Some Major Problems With Them In My Tomato Plants. They Started In The Squash, Bypassed The Cucumbers And Headed Directly Into The Tomatoes Where They Can Defoliate Most Of A Plant In A Day. It's Crazy I Don't Even Believe Tomatoes Are Good For Them I've Watched Them Bite Into The Fruit And Fall Off Dead. Would Getting Them Out Be The Same As Squash And Cuc's? Need Help, Thank You, Greg Johnson

It's unusual for squash bugs

It's unusual for squash bugs to attack tomatoes, preferring cucurbits such as squash and cucumbers. A similar-looking bug called the stink bug (aka shield bug), does attack tomatoes, but they tend to focus on sucking the juices from the fruit. The leaf-footed bug does similar damage. You might want to bring a bug to your local Cooperative Extension or a garden nursery horticulturist to ID it.
For control of squash bugs on tomatoes (and other true bugs such as stink bugs), it would be about the same as mentioned above for squash: handpick; use rowcovers; remove any eggs that you see under the leaves; place boards around your tomatoes and look under them in the morning, and destroy any pests there; sprinkle diatomaceous earth around the base of your tomatoes, to work as a barrier; remove weeds around the area; and remove mulch at season's end, to get rid of hiding places for overwintering adults. For more information about squash bugs, see:
Defoliation of tomatoes is often caused by caterpillars--check if you can find any hiding among the leaves, such as the large tomato hornworm. Beetles (such as the Colorado potato beetle) and whiteflies can also harm leaves. Diseases can also cause leaves to drop.
For a list of common tomato pests, including the stink bug, see:

I found many, many of these

I found many, many of these bugs this year on our zuchinni plants and the cucumbers. Once I noticed them, I went on a daily morning hunt for adult bugs, the nymphs, and the eggs. At first, I was killing 20 or more adults and innumerable nymphs and about a billion eggs! I used the dishwashing soap and spray bottle method and they just die right away. It does effect the leaves a bit, but it sort of gave an interesting look to the leave itself and I don't think that it hurt it in any major way. Soap and a considerable amount of diligence and our zuch's and cukes are BACK!

Have a few of these I've

Have a few of these I've found INDOORS EVEN BEFORE plants emerge. Have NO other veggies; only flowers.

Exterior base of house has been treated for mosquitoes and spiders; will this help? Add SEVIN? Anything I should apply INDOORS, and where?


Sometimes, the odorous squash

Sometimes, the odorous squash bug will overwinter indoors and are a real nuisance. Avoid squishing them as they will smell and stain.  The best you can do is to try to identify where they are entering. Seal all windows and building cracks; caulk all incoming pipes and wires. And, as you said, spray the exterior of your home with a pesticide (not inside). Do this in the fall. You'll need to ask your local cooperative extension for an insecticide that's approved in your area.

A six week  life cycle is the average so you may have two generations of squash bugs before harvest in the fall. Squash bugs start laying eggs when your plants are young in early summer. Eggs hatch after about two weeks and the nymphs feed for about a month before becoming adults. The adult females continue to lay eggs during this time

I have found the only way to save my squash, pumpkin, and cucumber vines (yes, once they kill all your squash they'll go for your cucumbers!)
1) use a decoy squash plant or two out in the open
2) grow your real squash in raised beds/boxes under ag ribbon
3) once they show up, pick over your plants every day
4) squish the eggs too! if you just scrape them off the leaves and they drop to the ground they'll still hatch
5) use the board/cardboard trick mentioned above
6) sprinkle diatomaceous earth around/on your squad plants- it cuts into their exoskeletons and kills them (warning: it also kills beneficial insects)

I don't use soap on my plants except in very dilute amounts- it does cause burning to the leaves in hot weather.

I live in the high desert in

I live in the high desert in southern california. I'm pretty sure I'm the only house with a garden in quite a large radius and this is my first garden.

I didn't think I'd have to deal with a lot of specialized garden bugs because of my isolation from farms, but these showed up and I can't bring myself to grab them lol.. I would up zip tying a couple pieces of sponge to bbq tongs so I could grab them without crushing them and then dump them in a red solo cup of water and laundry detergent, they drown in a minute or so.

Never gardened before, did a lot wrong but learning a lot and going to scale up big time next year :) Thanks for all the free resources!!

The squash "stink bugs" I

The squash "stink bugs" I have are not even touched by a soapy water spray! I had one survive the wash machine! They are invading my house too! ( Long Island, NY)

I have cleared away all the

I have cleared away all the vines & rot. Nothing but dirt now until next Spring. Is there something to treat the soil with now to rid it of the squash bugs?

Fall clean-up is the best

Fall clean-up is the best thing you can do. Wish for a cold winter as freezing temperatures are helpful in destroying the bug populations. Next season be on the lookout for any early bugs and remove them. Spread diatomaceous earth around the base of new plants next spring when the nymphs hatch.

This is definitely my summer

This is definitely my summer squash culprit!! I still have a few flowers on my squash plants but they look very sickly. Would it be worth trying to save them or should I just go ahead and pull them out?

The worth of trying to save

The worth of trying to save your squash plants is something only you can decide.
But consider: What's in harm in letting the plants keep on keeping on? Sometimes plants have enough strength to produce a few fruits, even when over run with these pests.
You could try a few of the solutions posted here (if you have not already), and see if you are able to salvage any of this plant's harvest.

Once the bugs have overrun

Once the bugs have overrun the plant, it is best to pull up the plant carefully and dispose in a large plastic bag. Seal it and put in the garbage.

Here's an easy method to rid

Here's an easy method to rid the squash of those nasty buggers once they have hatched: add a little water in your wet/dry vac, add a tiny bit of soap, and suck the pests off the vine and surrounding area. The soap will drown them fast and doing this daily or so will easily keep them in check! Thanks to my gardening friend, Master Gardener Cindy Rentchsler from Chino Valley, AZ for this awesome tip!

Farmer John is right on!

Farmer John is right on! Vacuuming squash bugs is a safe and excellent way to get rid them. When I find them I vacuum them off with my Dust Buster and dump them into a plastic pail with soapy water and they die very quickly. Works fast with no pesticides.

Rather than using pesticides,

Rather than using pesticides, mix a good dose of dish soap with water in a spray bottle (I use no particular ratio - just enough to make good suds), and spray directly onto the bugs. It only takes a few minutes and they'll be dead in their tracks.

would that work for broad

would that work for broad coverage over the whole garden , through a hose sprayer ? and will they move throughout all my
plants or are they particular to squash , cucumbers ? I have corn and bell peppers , watermelon and strawberries . My brussel sprouts and canteloupe seem only partially nibbled . . . ?

Do you have a problem burning

Do you have a problem burning your plants? I tried this one year and everywhere the soap a pray went, it burned the leaves, causing harm to the plants.

spray organic soap onto bugs

spray organic soap onto bugs in afternoon, then rinse plants in morning.
