For rats I created my own dead fall traps; nothing humane about that: it crushes them! In my ‘shop’ shed I put out poison baits; I don’t know what happened to the rats and I don’t care; they are gone! ¯\_🤨_/¯
I always worry about the poison under the house because I worry that it might make its way to my dog’s fenced yard but so far it hasn’t. Of all the troublesome wildlife, rats are overall the most dangerous in terms of carrying diseases, destroying property, and even harming humans. The rat I cornered in the house that one time actually bowed it’s back and growled at me....right before my husband shot it dead.
