I had a major infestation of squash bugs that took over my zucchini, squash, and pumpkin beds this year. I've heard that these pests can overwinter in the soil, so I'm looking for effective strategies to keep them from coming back next year. Should I consider skipping planting squash for a few years to cut down on their food source? Would using diatomaceous earth help to manage them?

One simple tip I've learned is to mound the soil around the stems of your plants. A local farmer suggested this to me, saying it suffocates the squash bugs and prevents them from moving up the stem to destroy the plant or lay eggs. It really changed the game for me, even if it sounds too easy! Just remember to stay on top of any powdery mildew by cutting off affected stems as you go.
I've battled squash bugs for over 25 years. Honestly, they're pretty unavoidable, but you can manage them by reducing their overwintering spots. Keep an eye out and actively kill adults and remove eggs. If you're vigilant throughout the season, they become much more manageable. It's all about staying proactive!
From my experience, waiting to plant until after July 1 is crucial. Most squash bugs lay their eggs in May and June. If you plant after July, you’ll give those pests less chance to ruin your crops. Trust me, I’ve tried everything over the years, and this method has worked wonders!
