Carpenter ants are more than just a nuisance; they can be a serious threat to the structural integrity of your home. Unlike termites, which consume wood, carpenter ants excavate it to build their nests, creating smooth tunnels that can weaken beams, joists, and other critical parts of your property over time. Understanding the signs of an infestation, how to eliminate it, and how to prevent it can save you time, money, and stress.
Whether you’ve seen a few large black ants crawling around or heard strange rustling in your walls, here’s what you need to know.
What Are Carpenter Ants?
Carpenter ants are one of the largest ant species found in Florida homes. They’re typically black or dark red. These ants are most active at night and often seek out damp or decaying wood for nesting. Although they don’t eat wood, their nesting behavior can cause substantial damage if left untreated.
They’re commonly found in bathrooms, kitchens, attics, wall voids, and areas around windows, especially where moisture problems exist.
How to Spot a Carpenter Ant Infestation
Knowing what to look for is the first step in preventing significant damage. Here are common signs that you may have carpenter ants:
1. Presence of Large Ants Indoors
If you’re spotting large black ants inside your home, especially during the spring and summer, there’s a strong chance they could be carpenter ants. These ants are particularly active at night and may be foraging for food.
2. Sawdust Piles (Frass)
Carpenter ants excavate wood to build their nests, leaving behind small piles of sawdust, often mixed with dead ant body parts. These piles, known as frass, are typically found near baseboards, window sills, or anywhere wood structures may be present.
3. Rustling Sounds in Walls
In quiet environments, you may hear faint rustling or crinkling noises inside the walls. This sound is produced by carpenter ants moving or chewing through wood to expand their nests.
4. Winged Ants Inside Your Home
Winged carpenter ants (swarmers) emerge during mating season. If you spot them indoors, there is likely a nest inside your home.
5. Hollow-Sounding Wood
Tapping on structural wood that sounds hollow or crumbles easily may be a sign of an active infestation.
How to Get Rid of Carpenter Ants
If you suspect a carpenter ant infestation, it’s essential to act quickly. For comprehensive advice and expert help, visit our how to get rid of carpenter ants page.
1. Locate the Nest
Finding the main nest is key. Carpenter ants often have satellite nests, so it’s important to identify and eliminate both the parent and satellite colonies.
2. Use a Professional-Grade Carpenter Ant Killer
DIY solutions are rarely effective against carpenter ants. Instead, rely on professional products and application methods that target ants at the source. For trusted treatment options, check out our recommendations for carpenter ant killer.
3. Seal Entry Points
Prevent ants from entering by sealing cracks, gaps around windows and doors, and openings around plumbing or wiring.
4. Reduce Moisture
Repair leaky pipes, roofs, or vents and ensure proper ventilation in attics and crawl spaces. Carpenter ants thrive in damp conditions.
5. Remove Damaged Wood
Replace any soft, rotting, or moisture-damaged wood to eliminate ideal nesting areas.
How to Prevent Carpenter Ants from Returning
Once the infestation is under control, prevention becomes your best defense. Consider the following tips to keep your home protected:
Regular Inspections
Have a trained technician inspect your property for early signs of pest activity. Routine checks can catch issues before they become major problems.
Routine Pest Control Treatments
Preventative treatments create a protective barrier around your home. For those in Florida, pest control Sun City Center FL plans are available to provide long-term protection.
Keep Firewood and Mulch Away from the Home
Carpenter ants love to nest in damp wood. Store firewood off the ground and away from your foundation, and avoid using excessive mulch near your home.
Maintain Landscaping
Keep shrubs and tree branches trimmed and away from the home. Overhanging branches can act as highways for ants.
Store Food Properly
Carpenter ants are attracted to sweets and proteins. Keep food sealed and clean up crumbs and spills promptly.
