Our yard is being overrun by garter snakes! We have always had some snakes in the yard but this year they are everywhere and over the weekend we saw MANY, MANY smaller snakes coming from under some plants in our yard (as if they were young snakes leaving a nest). I don't mind having a few snakes around but am worried about them getting into our house or crawl space. Would appreciate more info on them (will they leave the nest and venture off? will they return next year to the same spot?) and some help in getting rid of them. Thanks!
