The massive gator, measuring 10 feet, 11 inches long and weighing 550 pounds, tore through the screen around the Deep Creek family’s lanai, the Charlotte County Sheriff's Office said.
"Water Safety Month, Tip #37: Always check your pool before diving in!" the sheriff’s office said in a Facebook post.
The sheriff’s office shared photos of the visiting gator "taking a dip" in the "nice, cool water."
Deputies and an alligator trapper from the Florida Fish and Wildlife Conservation Commission (FWC) worked together to wrangle the wayward gator.
It wasn’t immediately clear where officials brought the gator after interrupting its swim.
"If you see an alligator leave it alone, give it its distance," Dan Costell, associate curator for reptiles and fish at Zoo Tampa at Lowry Park, told FOX13 Tampa.
The FWC said that alligator mating season typically occurs in May or June, while hatching happens from August through September.
