1. Planter's method for controlling large bugs that are too slow to fly away (Japanese beetles, vegetable weevils). Or, use it to store larvae, before tossing them, a much more palatable approach than squishing! Since life cycles of insects are predictable, it requires less time than you would think. Coitus interrruptus gives you a big bang for your bucks, too!
Stir a few drops of dish detergent and a teaspoon of salt in about 1 1/2 cups warm water in a pan, ideally one with a handle. Hold pan underneath the insect(s) and tap into brew. After a couple days, dispose in ground and cover with soil. We have been able to keep the Japanese beetle and vegetable weevil population tolerable by doing this once or twice a day.
