anyone that grows organic is going to appreciate this. last year aphids, earwigs, and a bunch of other nasties were totally invading my yard, and killing my plants. as I grow organic pesticide is outta the ?. I found ARBICO, this company sells beneficial insects. I bought three praying manti egg cases. they were really inexpensive as well. I put one in my yard and my neighbors on both sides were thankful for the one I gave them. within a couple of weeks I couldnt look at one of my plants without seeing a little manti happily munching aphids etc. the bonus was that they lived out their life cyles and layed their own egg cases. now I have an ongoing population of manti!! I even bring the babies i find inside and turn em loose on my bonsai and houseplants. also consider ladybugs these ferocious predators are the toughest bug you can imagine they eat every bug you dislike. only problem with lady bugs is that when they have eaten every nasty bug in your yard they fly off to find more food. some hang around and I see more of them this year than I did last year. anyways this works well give it a try you won't be sorry....
