Hi, Crickets and grasshoppers can be very difficult to control, especially in their adult form when they are almost impenetrable to insecticides. It's best to catch them in their younger nymph phases. The good thing, though, is that their populations tend to go up and down, depending on weather conditions so some years you may not have any to deal with at all. Now, there is a chemical control sold by the Ortho company that can control crickets and you can find it at most garden centers. However, if you want to try an organic method you could try a rotenone/pyrethrim based insecticide which is made with natural ingredients. I used it once for grasshoppers and had some luck with it, but it wasn't completely effective like a chemical control would be. You can buy that, and other organic products, from Gardens Alive at www.gardensalive.com
