Trappers say its become a year-round problem and they take about 3,000 to 4,000 calls a year.
Rats can easily squeeze their way into a tiny hole in a roof.
"Anything over a half inch, the rats can flex their skeletal system and get into the attic space," said Brian Payne with First Coast Wildlife Services.
Payne said rats are usually the first rodent that gets into attics and he said they pave the way for other animals such as raccoons to get in as well.
