Squash bugs wreck my plants every year. I’d rather not spray a bunch of harsh stuff, especially near food we eat. What actually works to keep them under control?
Oh, squash bugs — every squash grower’s nemesis. The good news is you’ve got some solid options that don’t involve anything harsh.
Start with eggs. That’s where you win or lose the battle. Flip your leaves over every few days and look for clusters of bronze-colored eggs, usually laid in a tidy group on the underside. Scrape them off into a bucket of soapy water. Takes a few minutes but it makes a real dent.
Trap them. Lay a piece of cardboard or a board near your plants at night — squash bugs like to congregate under cover in the dark. In the morning, flip it over and drop them in soapy water. Old-timers swore by this, and it works.
Companion planting helps. Nasturtiums and dill planted nearby seem to confuse or deter them somewhat. Not a silver bullet, but worth doing since you’re planting those areas anyway.
Mulch strategically. Heavy mulch gives bugs more hiding spots, so during squash bug season I pull mulch back a bit from the base of the plants. Makes it easier to spot them too.
Keep the plants healthy. Strong, vigorous plants handle pressure a lot better than stressed ones. Consistent watering and some compost worked in before planting goes a long way.
Diatomaceous earth sprinkled around the base can slow them down — food-grade, totally safe near edibles. Reapply after rain.
Honestly, regular scouting — every couple of days in peak summer — is the biggest factor. Catch them early and you can stay ahead of it. Let them get established and it’s a whole different fight.
What variety of squash are you growing? Some are a bit more resistant than others, and that might be worth knowing for next season.
