I have always had good luck with snap traps. They are about a dollar each, you can buy a half dozen and bait them with peanut butter. You'll probably start catching mice within a day of setting the traps.

D-con is a problem because it travels up the food chain - so any predator (cat, raptor) that eats a poisoned mouse will be poisoned.

Cats are good. Traps are good.

Can you use it to make a nice hot pile and decompose some browns, like, say, shredded junk mail or leftover autumn leaves? Should go pretty quick.

Whatever you do don't use the glue traps. They're just horrible. We used one once and seeing that first mouse dragging the trap across the room with one foot that wasn't stuck to the trap proved to me I wanted nothing to do with 'em. They should be banned, most inhumane traps ever made.

Cats and/or dogs. I think Terriers like chasing mice.

We, and all our neighbors, have had rodents like crazy this year- little gray field mousey things (maybe voles), chipmunks, and I don't know what else. They dug up all my new plants for months in early spring. I tried a havahart for weeks and caught nothing. The only thing I caught with the snap trap was a cardinal which was beheaded. I finally used D-Con and have seen no rodents and had no more garden damage. Neither have the neighbors.

I put the D-Con under upside-down flower pots, staked so they couldn't easily be removed by other animals. Worked great.

I have lived here 24 years and never had rodents before. I'm thinking it might be due to the drought; We now have over a 7" rain deficit.
