How to Identify and Get Rid of Flea Beetles
This article says that the flea beetles are repelled by nasturtiums but actually, they seem to be ravaging mine this year.
Yes, nasturtiums can be used as a trap crop; they will take the focus of the flea beetles away from the more valuable crops you are growing.
This totally did NOT work, nor did placing peppermint leaves on the eggplants. I saw more flea beetles after I sprayed than before. I think they loved it. I only have 6 eggplants, so I picked the beetles off and put them in soapy water. That killed them!
Tried this home brew recipe and 5 mins later, flea beetles were back, happy as ever. This treatment totally does not work. Just FYI.
No, cucumber beetles are not generally a problem indoors, unless they’ve hitchhiked on your clothing or a plant that you brought inside. Even then, they are unlikely to reproduce indoors.
hi, We have some mustard grown here, unfortunately, flea beetle left so many holes on them. After that, I found that the hole edge get purple, so it looks like there are so many purple holes on mustard. It's different from holes flea beetle left on other vegetables. Do you know the reason for this?
Some varieties of mustard naturally have a purplish tinge to the leaves, so our guess would be that the tissue immediately surrounding the holes in the leaves starts to die and lose its green chlorophyll, leaving the dark color around the holes. On the other hand, a fungal disease called alternaria leaf spot may cause purplish-black lesions in leaves. Search google for an image of alternaria leaf spot and see if it matches what you’re seeing. If alternaria leaf spot is the culprit, remove heavily affected leaves and avoid planting mustard in the same spot next year.
