Answers:    I don't close to insectacide in the garde where on earth food is grown.
You might try making a tea of chewing tobaco and mouth wash, 50/50 mix and put this liquid in a spray bottle and spray it on the plants.
Soapy sea if you do not want to use common insecticides. Put a roomy squirt of dish soap in a spray bottle near water. Spray anywhere where on earth there are insects and they should die. Repeat till adjectives are gone. Also works for ants, wasps, box elder bug, aphids and many other insects. It works by with alacrity suffocating the bugs.
