I have a real problem with squash bugs every year in my vegetable garden. I live in Zone 8a. Since I have applied the kaolin clay and water as prescribed using my pump sprayer, I have noticed a few squash bugs but certainly not the numerous ones I encounter each year. Using this Surround WP as well as picking off the squash bugs, (with my rubber gloves, of course), I have noted a tremendous decrease in this species which wreak havoc on my zucchini, yellow crookneck, cucumber plants, and Israeli melons. I will continue to use this product in the future!
