Spring is right around the corner and wow....I've got one mess of a lawn to deal with this year. Late last summer and fall the moles, racoons and skunks tore my lawn up something fierce, both front and back yards. I've had semi-bad years before with these pest's, but last year was the worst ever. Fact is the moles are out already. Yesterday was the first time that I took a walk in my backyard since the snow melted and I could feel thier tunnels all over under my feet. It's bad. I know they're all looking for grubs and obviously I've got to get rid of them. But I'm leary of putting harsh chemicals down because our water comes from wells. I've been holding off but this year I've got to do something. Any recommendations for killing the grubs without reaking havoc on our water supply? Thanks.
