Good sleuthing. Yes, small,Good sleuthing. Yes, small, reddish-brownish eggs on the underside of leaves in evenly spaced groups indicate squash bugs. Frankly, this is the most loathsome of pests and there is not a lot you can do once your plants are attacked. Control in organic gardening is done before seeds are even planted by removing overwintering sites with post-harvest tillage, removing and even burning all vines and debris, cover cropping, rotating crops, using tightly secured row covers until flowering starts, planting resistant types (e.g, 'Butternut'), interplanting buckwheat to attract a predator fly, companion planting with bug-repellant flowers (e.g., marigolds, nasturiums), and planting nearby "trap" crops of plants that squash bugs prefer (e.g., Hubbard). If you catch the pest early --on just a few vines--hand pick the pests and crush the eggs daily. Some organic gardeners say using diatomaceous earth (DE) slows them down. Others say to spray with Neem oil, a natural pesticide; spray on all leaf and stem surfaces. One expert gardener recommends Bayer Advanced Fruit & Vegetable Insect Control. Ask your local garden center about these products and follow directions very carefully. One of our readers says to put the squash bugs in a blender, add some water, wait a day, and spray THAT on the pests and it works. Warning: they are very smelly! Now, Sevin is a chemical. I believe it's for the base of the plant, below the flowers, but follow the directions very carefully. Note that Sevin is extremely toxic to honeybees (our dear pollinators). Many farmers use pesticides and will tell you timing is critical. Application must happen early during maximum egg hatch. Otherwise, it may be back to those preventative controls.
