Why Ants Are Still Active Inside Florida Homes in Winter
At Clements Pest Control, we often get the same question from Florida homeowners each winter:
“Why are ants still crawling around my house when it’s cold outside?”
If you’re seeing these tiny intruders during the cooler months, don’t worry — you’re not alone. Let’s uncover why ants remain active in Florida homes during winter and what you can do about it.
Warm Winters, Busy Ants
Unlike northern states, Florida rarely experiences the deep freezes that drive ants into dormancy. Instead, our mild winters allow species like ghost ants, Argentine ants, and carpenter ants to stay active year-round.
Your warm, humid home offers the perfect shelter — complete with food, moisture, and cozy hiding spots.
Why Ants Invade Your Florida Home in Winter
Even in winter, your home offers ants three things they love:
Warmth: Indoor heating makes your space more comfortable than the outdoors.
Moisture: Leaky pipes, steamy bathrooms, and kitchen sinks keep them hydrated.
Food: Crumbs, pet food, and unsealed containers become buffet lines for ants.
Florida homes, especially older builds, often have tiny cracks or entry points around doors, windows, and foundations — an open invitation for ant colonies.
Watch Out for Carpenter Ants
Some of the most destructive winter invaders are carpenter ants. While they don’t eat wood, they tunnel through it, weakening your home’s structure from the inside.
What You Can Do
Ants in Florida don’t take the season off, which means your pest control shouldn’t either. Here's how to protect your home:
Seal cracks and entry points
Store food securely
Repair leaks and reduce moisture buildup
Schedule seasonal pest control. even in winter
