they love weeds, so if you let the weed grow around the sides of the gardens and keep the weed down around your plants............they love bugs...........so my thoughts are if you don't have chicken or ducks to eat them for you.....you could put 2 layers of newspapers down around the plants leaving a 8 inch ring for the plant to breathe....and I use grass that I got from mowing with a bag and for many years had a man how mowed lawns and he would drop off clean grass for me to spread on the newspaper.............that kept the bugs down a lot......you also could spray your plants with 1 teasp liquid hand soap with 1 qt water when the sun passes over.....
