We talk a lot about organic gardening, a lot of us garden simply to be able to eat organically grown produce. While there are many organic pest recipes and solutions out there one of the easiest is to put up a bat house and attract bats to your garden. Not only do they eat a lot of mosquitoes according to Wiki answers they also eat “moths, , flies, crickets, grasshoppers, planthoppers, leafhoppers, ants, assassin bugs, spittle bugs, cicadas, dragonflies, termites, stink bugs, and beetles” That is a lot of pests that you would not have to control if the bats were around taking care of them for you. Bats.org has a lot of pdf files on how to attract bats, bat identification and plans for building a bat house. Why not put these little guys to work for you.
