Q. Every year my zucchini plants are infested with grey-colored beetles that destroy my zucchini. How do get rid of the beetles?


Squash Bugs
A. Most likely squash bugs. You can plant late, in June, after their infestation time has passed or you can hand pick them as you see them. You must do this as they appear soon after planting and get rid of them as soon as you see them. Do this for about three weeks and the numbers will be greatly reduced.

Or you can vacuum them with a handheld vacuum cleaner and vacuum the undersides of the leaves. You can use pesticides suitable for squash bugs but be sure to spray the undersides of the leaves. Do not spray plants when in bloom. Spray very early in the am or at sunset when bees are not active.

  1. if, and after you vacuum them, make sure you securely block/cover the end of the hose, otherwise they will crawl out and return to the plant ..

  2. We are trying something in the Children's Gardens on the Las Vegas campus. Ordinary household white flower. They are supposed to eat it and then their insides will gum up and they will die. Will let you know if it worked.

    1. Ordinary household white flower? Did you mean white flour like the cake mix kind?

  3. I've heard the same about corn meal. That didn't work for me two years ago when they decimated my squash plant in about 10 days. If the corn meal did kill any, it didn't kill enough.

  4. I read that a 1/2 tblsp of dish detergent in a gallon of water in a sprayer works well to kill the bugs. I battled them well this last yr. with this.
