What kind of homemade insecticide do I use for cucumber beetles and stink bugs?
Try spraying a solution of garlic in water. May want to add some hot pepper. Try filtering it before spraying. I've had trouble with clogs.
Diatomaceous earth dusted on the plant may also work if there's no rain in the forcast. Use a mask or dust standing upwind.
If you don't have too many plant, hand picking really does knock em down fast.
