A Florida man says he’s got a serious monkey problem.

Brian Pritchard of Ocala says troops of rhesus monkeys swarm his property at least two times a day to swipe food in a feeder meant for deer. He initially set up cameras around his property to photograph the deer but instead captured pictures of dozens of monkeys taking over his backyard. Pritchard said as many as 50 monkeys have been present at a time.

The primates have easily eaten 250 pounds of food in recent days.

Officials believe the monkeys most likely came from Silver Springs State Park about four miles away. The park recently shut down two areas because of the increased monkey presence. It’s estimated that 200 monkeys live in the park, but many are seen beyond its boundaries.

Reportedly, the monkeys appear to be organized and aggressive.
