Here in Central Indiana, there is one thing that is a near-certainty for every garden: the inevitable infestation of the squash bug. Each year it never fails: your summer squash plants are gigantic and producing like crazy. And then one day, you might notice a handful bugs. The next: a few more.
The next day? Your once-beautiful squash plant is crawling with bugs, and the entire plant has died, apparently overnight. Not only can they do a crazy amount of damage to squash plants, but they can also attack other cucurbit varieties (cucumbers, melons, and pumpkins).

So what can you do about these evil little jerks? We decided to take a very scientific survey* to find out what area organic farmers and gardeners do to beat squash bugs into submission. Since this issue will likely befall your garden at some point, we thought we’d share everyone’s feedback here for future reference. Enjoy, and may your squash plants live long and prosper!
Tips for maintaining your squash plants – and sanity – against squash bugs, straight from Central Indiana farmers and gardeners:
- “So far its daily physical intervention, inspecting leaves, removing eggs, and adults, and treating with Diatomaceous earth around base of plants where they hide. Dr. Bronner’s castile soap with peppermint will work mixed with water and sprayed directly on insects. You can also use floating row covers early in season (you will have to pollinate yourself).”
- “I pull all leaves with eggs or midges on them and throw them in the trash. The chickens seem uninterested. I second, or third, the drowning them in soapy water method. Hand picking seems the best way.”
- “I recently purchased a book called “The Wildlife-Friendly Vegetable Gardener.” The author, Tammi Hartung, is great and one of the ways she suggests repelling squash bugs is to sprinkle black pepper around the plants. I haven’t done this yet but did spray the plant with neem oil mixed with dish soap. That has helped.”
- “I have a spray bottle filled with soapy water and cayenne pepper and spray the leaves. So far it’s kept them off this year. If I find one I just squish it. Same with the eggs.”
- “Transplant as early as possible is my tip. Squash bugs are inevitable.”
