Will boric acid kill mice which have housed themselves outside in our window wells? I thought I could sprinkle it down inside the window well, as I see them running around on the rocks!

You must be thinking of borax (a powder) as opposed to boric acid (usually a liquid)? I have never heard of either of them having much effect on animals. Borax does affect insects. I would keep looking for a better solution. (09/28/2010)

I have a plastic container of Boric Acid called Roach Away made by Enoz. The ingredients are "active Ingredient Boric Acid 99% and Inert Ingredients 1%." I think the Inert ingredients are probably to keep the powder from becoming one big hard lump due to humidity. We bought it in 1996 at a hardware store in Tennessee when we rented a motor home in Winston Salem NC that had cockroaches. We sprinkled the Boric Acid powder under and behind everything in the Motor Home and never saw another Cockroach.
My container which is still about 3/4 full is still mostly a powder. Does have a few tiny lumps in it. There is a "keep out of reach of children" caution on it. With a Statement of practical treatment which says immediately contact poison control center or physician if swallowed. If eye contact occurs flush eyes with plenty of water. Get medical attention if irritation persists. It is Manufactured by Wilbert Home Products Inc 404 Park Avenue St Louis Mo 83110.
We use humane traps for mice, and release them in the woods behind our house. Our children always had gerbils when they were young and mice remind us too much of the gerbils so I think that is the reason we can't bring ourselves to kill them. (09/29/2010)
