If the freaks come out at night, then the creatures come out in the cold.

Low temps have Miamians bundling up and rats and mice running into your homes for a piece of the warmth.

"Within a night or two, boom, you get 'em!" said Lance McDonald of Terminix, as he shows off how a standard mouse trap works, a la the Tom and Jerry cartoons.

A bone-chilling snap ensued, as the trap fired and steel hit wood.

"Holy mackerel, snapped 'em good!", McDonald said. You can tell he's the kind of guy who enjoys his job.

McDonald told us cold weather draws new customers to pest control companies, with almost all the new customers over the last two weeks complaining about rats and mice. Why? Because the cold air ushers the unwanted, creepy critters inside.

"It's like you and me. We get cold we put on a jacket. Same thing with them, they're gonna find someplace warm to go," McDonald said.

Makes sense, in a creepy kind of way.

But pest control companies aren't the only ones raking in the cold, hard cash during this climate freeze.

Good luck finding a space heater in South Florida these days. Pretty much every store, including Home Depot, is sold out. They've got plenty of portable air conditioner units at the Miramar store, but the shelf for space heaters is empty.

"We've probably sold about 15-thousand dollars worth just in our store alone, " Home Depot store manager Charlcina Paul said. "Apparently we weren't expecting it to be so cold, we had some on Monday and by Tuesday-Wednesday, we were completely out."

If you've got a space heater, be careful with it. We saw wiring completely fried at a Pembroke Park trailer park, done in by a space heater overloading the circuits, and the same thing happened in another trailer just around the corner. In that one, an elderly woman and her home health aide were using three space heaters simultaneously.

"These units overloaded the circuitry to the mobile home and it resulted in sparking and smoke coming from one of the outlets," said Mike Jachles of the Broward Sheriff Fire-Rescue department.

The key is to make sure not to plug your space heater into an outlet that can't handle the power load, and make sure you don't leave it on too long, or when you sleep, or when it's unsupervised.

Now back to the rats: they can squeeze into your home through an opening the size of a quarter. So it's best to inspect your house for weak spots, for unintentional welcome signs to furry invaders.

Or you can count on adding the snap of a mouse trap to your cold snap.
