Florida Carpenter Ant Infestation

Florida Carpenter Ant Infestations

The Florida carpenter ant is one of the ants homeowners here deal with most. Locals often call it the bull ant or sugar ant, and it is easy to spot thanks to its orange front half and black rear. Colonies usually start outdoors in trees, stumps, palm boots, landscape timbers or under mulch. From there, workers find their way inside through gaps around doors, windows and vents, and through the openings where pipes and wires enter the walls. Once inside, they head for places with a moisture problem: a wall void next to a leaking pipe, damp attic insulation, the hollow space behind a window frame or a soaked subfloor.

Many people first notice them when winged queens and males leave the nest to mate. These flights happen mostly in late spring and early summer, and the winged ants tend to gather on windowsills and around sliding glass doors. A cluster of winged ants indoors is a good sign that a nest is close by.

What Do Florida Carpenter Ants Eat?

Their main food is honeydew, the sugary liquid made by aphids, scale insects and mealybugs on shrubs and trees. They also take nectar, ripe fruit and both live and dead insects. Indoors, they look for sugar, syrup, pet food, grease and crumbs, and during dry spells they come in for water. Most activity happens after dark. Workers get moving around dusk and keep at it through the night, so you may see only a stray ant or two during the day while dozens use the same route at night. Their trails are loose and scattered rather than neat lines, and they like to follow edges such as baseboards, pipes and wires.

Where Do Florida Carpenter Ants Nest?

Despite the name, these ants do not eat wood. They prefer ready-made spaces: hollow doors, wall and ceiling voids, gaps behind trim, pockets under insulation and wood that has already started to rot. They can hollow out soft, decayed wood, but they seldom tunnel through sound, dry lumber the way some northern carpenter ants do. Finding them inside usually points to a leak, poor drainage or wood that stays wet. A large colony may also spread into several satellite nests in different parts of the house. Fixing the moisture problem matters as much as treating the ants, since wet, rotting wood leads to costly repairs of its own.
