Hard to believe, but yes, in parts of Florida, monkeys are a pest. "They're not native of course, but there are areas where you've got groups of them and you don't want one of them getting into your yard or your house," says Harrison. "They might seem like a lot of fun, but they can break a lot of stuff."
To prevent a monkey raid--or to make your property less homey to more common pests like rats and possums, make sure to pick any ripe fruit from your trees as soon as possible and clean up fallen fruit regularly; don't let pet food stay out all night and keep garbage containers tightly closed. "Much of pest control is about making the creature look for food and shelter elsewhere," says Harrison.
