Many homeowners assume pest problems disappear in winter—but in Southwest Florida, that’s rarely the case. Thanks to our mild temperatures, ants remain active year-round, and winter often brings an increase in indoor ant activity rather than a break from it.
Understanding why ants show up in winter—and what to do about it—can help protect your home before infestations grow worse.
Why Ants Are Active During Winter in Southwest Florida
Unlike colder climates where ants go dormant, Southwest Florida winters are warm enough for colonies to stay alive and functioning. As temperatures cool slightly, ants often relocate closer to structures or move indoors to find:
Warmth
Food sources
Moisture
This is why homeowners frequently notice ants in kitchens, bathrooms, along baseboards, near windows and doors, and around patios or pool decks during winter months.
Common Ant Species Seen in Winter
Several ant species remain active in Southwest Florida throughout the winter, including:
Ghost ants, commonly found indoors near sinks and kitchens
Sugar ants, attracted to food spills and crumbs
Fire ants, which remain active outdoors and can become more aggressive as conditions change
Each species behaves differently, which is why proper identification is key to effective control.
Why Winter Ant Problems Shouldn’t Be Ignored
Seeing ants in winter is often a sign that a colony is relocating or expanding, not disappearing. Without professional treatment, colonies can grow and spread quickly. By the time spring arrives, homeowners may face:
Larger infestations
More frequent indoor activity
Increased risk of repeated treatments
Addressing ant problems early helps prevent long-term issues and reduces the chance of costly infestations later in the year.
