@droolinggardener: Alas, there's no easy cure for squash bugs, but your army grew the year before it appeared and you can adopt practice that will shrink the army next year. Keep your garden free of debris, meaning stuff the adult bugs can hide under at night (stray pieces of wood, stalks, fallen leaves in heaps). Also, the reverse. In the evening lay a board beside the plants. The bugs will gather under the board for the night. Come out early each morning, lift the board and crush the bugs. Another method. Inspect the under side of leaves early in the season to spot the eggs, which are tiny and orange and usually in clusters, which is handy because the remedy is to rub them off. I use my thumb with my fingers behind the leaf for support and roll the eggs aways so the fall to the ground. You'll be suprised how many clusters you find and how fast the bugs hatch, which is why you have to start early. When the bug are young and tiny you can roll them away too and you'll crush most them as you do. If you repeat this regime every spring the army will grow smaller and stay small.
An organic soap spray such as Safer's kills the young bugs. Time the spray for the few days when the baby bugs are emerging from the eggs and youspray the top and the bottom of the leaves. If your eyes are sharp and you get close to leave you will see the young bugs walking around. Time to spray.
Some squashes resist the bugs fairly well: try Butternut, Royal Acorn, or Sweet Cheese.
Hope this helps. Good luck!
