We had problems with groundhogs eating our garden and causing destruction to the foundation of the house and garage. Tried a live trap, and trapped one ground hog, however the second managed to pry a corner away and escaped. This one could not be trapped with a live trap. I used the 220 trap and placed it in front of his hole, and the next morning - there he was. It was quick and painless, no blood. I am very satisfied with this product.
