ditto. solved my problem. don't know where they went, never saw any bodies, but they're gone and that's what countsPoison. Put it in some sort of bait box that nothing else can get into. We have a wooden box with a small hole in the end that we put the bait under, and weight it down with a rock. Rats are the only thing that can get into the bait. We have never seen dead or dying rats, nor have I ever had a chicken, cat or dog kill or eat a poisoned rat.
