What is Florida Carpenter Ant?
Florida Carpenter Ants (Camponotus floridanus) are one of the most common wood-nesting pests found in Florida homes. Although they do not eat wood like termites, Florida carpenter ants excavate galleries inside damp or decaying wood, which can lead to structural damage over time. This ant is a large, reddish-brown and black ant species commonly found throughout Florida and the southeastern United States. While they do not sting, Florida carpenter ants can bite and spray formic acid, causing irritation.
What Do Florida Carpenter Ants Look Like?
The Florida Carpenter Ant is one of over 900 species in the Camponotus genus, known for its ability to excavate nests in wood. These ants do not eat wood but tunnel through damp or decaying wood, often nesting in attics, wall voids, and wooden structures around homes. Some Camponotus species nest in soil or preformed cavities, but Florida carpenter ants are commonly found in trees, logs, and structural voids. They are one of the largest ant species in South Florida, with workers ranging from 6 to 11 mm and winged reproductives reaching up to 20 mm. Their reddish-brown and black coloration makes them easy to spot as they forage or fly indoors and outdoors, especially at night.
Biology of Florida Carpenter Ants
The Florida Carpenter Ant thrives in warm, humid environments, nesting in damp or decaying wood, attics, wall voids, and outdoor structures. Unlike termites, they do not eat wood but hollow it out to create tunnels for their colonies. These ants are most active at night, foraging for sweets, proteins, and other food sources around homes. Florida Carpenter Ant colonies will have only one queen, but will make over a dozen nearby satellite nests. Often the main nest will be in a nearby tree but we will find several satellite nests in the customer’s home. Colonies can grow into the thousands, with winged reproductives swarming in spring and summer, often invading homes. Professional pest control in South Florida is essential to eliminate nests and prevent structural damage caused by these invasive ants.
Behaviors, Dangers and Habits of Florida Carpenter Ants
Florida Carpenter Ants are nocturnal foragers, often seen trailing along walls, ceilings, and outdoor structures in search of sweets and proteins. They establish large colonies in damp or decaying wood, nesting in attics, wall voids, tree stumps, and wooden decks, making homes and businesses in South Florida highly susceptible to infestations. While they do not sting, these ants can bite and spray formic acid, causing skin irritation. Their tunneling weakens wooden structures over time, leading to potential damage if left untreated. According to the University of Florida IFAS Extension, Florida carpenter ants commonly nest in moisture-damaged wood inside structures. Swarms of winged reproductives appear in spring and summer, signaling an active colony nearby. Without proper pest control, these ants can quickly expand their nests, making infestations harder to eliminate.
5 Ways To Prevent Florida Carpenter Ants in Your Yard
Eliminate Moisture and Rotting Wood
Florida Carpenter Ants prefer damp, decaying wood for nesting. Fix leaks, improve ventilation in attics and crawl spaces, and remove rotting wood around your home.
Seal Entry Points
These ants can enter through small cracks, gaps in siding, and openings around windows and doors. Use caulk, weather stripping, and sealants to block potential entryways.
Trim Trees and Shrubs
Carpenter ants use branches and overgrown vegetation to access homes. Keep trees, shrubs, and bushes trimmed away from your home’s exterior to prevent easy access.
Store Food Properly and Keep Surfaces Clean
These ants forage for sweets, proteins, and greasy foods. Store food in sealed containers, wipe down counters, and remove crumbs to eliminate food sources.
Use Professional Pest Control
Since these ants can have hidden satellite nests, professional pest control services are the most effective solution for complete elimination.

5 Ways To Keep Florida Carpenter Ants Out Of Your Home
Following these tips can help prevent Florida Carpenter Ants from becoming a problem.
Store Food Properly
Ants are highly attracted to food inside the home. Keep food stored in airtight containers, clean up crumbs or spills immediately, and regularly empty trash bins with food waste.
Clean Regularly
Ants are resourceful and will find even the smallest bits of food. Regularly sweep, and wipe down countertops, especially in the kitchen and dining areas, to remove potential food sources. Pay attention to corners and crevices.
Reduce Moisture
Fix leaks and eliminate damp areas to remove the moisture that Florida Carpenter Ants seek out. Repair dripping faucets, leaky roofs, or poor drainage, and replace any damp or rotting wood.
Don’t Leave Pet Food Out Overnight
If you have pets, avoid leaving their food out overnight. Ants are attracted to pet food, so clean up any leftover food, or place pet dishes in a shallow tray of water to create a barrier.

Frequently Asked Questions
Are Florida carpenter ants dangerous to homes?
Florida carpenter ants do not eat wood, but they excavate damp or decaying wood to build nests. Over time, this can cause structural damage if infestations are left untreated.
How can I tell Florida carpenter ants from termites?
Carpenter ants have elbowed antennae, a narrow waist, and larger bodies. Termites have straight antennae, thick waists, and lighter-colored bodies. Carpenter ants also leave wood shavings, while termites leave mud tubes.
Where do Florida carpenter ants usually nest?
They nest in moisture-damaged wood, wall voids, attic beams, window frames, and sometimes outdoors in tree stumps or landscape timbers.
Why are Florida carpenter ants common in humid areas?
They prefer damp environments. Florida’s humidity and frequent rain create ideal conditions for moisture-damaged wood, which attracts carpenter ants.
Do Florida carpenter ants bite?
Yes, they can bite if handled, but they are not aggressive and rarely bite humans indoors.
Will spraying kill a Florida carpenter ant infestation?
Surface sprays may kill visible ants but usually fail to eliminate the nest. Effective control requires locating and treating the nesting site.
How do I prevent Florida carpenter ants from entering my home?
Reduce moisture problems, repair wood damage, trim vegetation away from the structure, and schedule professional inspections.
Should I call a professional for Florida carpenter ant control?
Yes. Professional inspection and targeted treatment are the most reliable ways to eliminate carpenter ant nests and prevent recurring infestations.
