Poisons, for this reason none are used around my property as I have rescue cats and wildlife living in the woods around me, do not want to poison them. Between my cats that go out in am after dawn, (never between dusk and dawn as that is hen larger predators are active as are their prey) , coyote, hawks, owls and feral cats I have no nouse, rat problems. If they do get inside during rainy, cold, hot days, the cats make quick work of them. Plus there is a ring neck and black snake in my basement, they got in by accident. Conservation said unless afraid of snakes, let them be, they will kep bugs, rodents down. So as far as I know, they are still there, catching roaches, mice, etc. for me.
