I feed squirrels in my backyard. I don't see them I think my neighbor did something. He hates me for some reason but when I came home the food wasn't eaten. I think he used some type of air gun but their nests are close. I would think they'd still come back. Can we kill them?
By "them" I assume you mean, "Can we kill squirrels?" Our native tree squirrels are protected animals. Many towns around Idaho have non-native fox squirrels or gray squirrels living within city limits. The non-native squirrels are not protected under Idaho law.
