I was going through lots of food from ground squirrels. My feed store sold me a squirrelinator. The first day I caught 15. I have caught no less than 8 every day since. No wonder my feed bill was so high. If you have a problem with ground squirrels, get one of these. They sell them on line.
They say you can relocate them, or put them in a water pan that comes with it. I have not had to do that. The seem to die easy. I think they fight or the heat kills them.
