If you’ve spotted ants in your home, you may wonder whether you’re dealing with black ants or carpenter ants. While both are common household pests, the differences between them are crucial because carpenter ants can cause significant structural damage to your home.
In this blog, we will find out the key distinctions between black ants and carpenter ants, their behaviors, and how to handle an infestation.
Common indicators of carpenter ant damage include hollow-sounding wood, which happens when tapping on beams, floors, or walls produces an echo due to internal cavities. Their nests consist of smooth, polished tunnels within the wood, distinctly different from the rough, soil-filled tunnels made by termites. You might also spot warped or uneven floors if ants have established nests underneath them..

Carpenter Ants vs. Black Ants
While carpenter ants and black ants may appear similar, they have distinct differences in size, behavior, and the type of damage they cause. Knowing how to tell them apart is essential for effective pest control, as carpenter ants pose a greater risk to your home’s structure than black ants. Here’s a closer look at their key differences:Carpenter Ants
-
Size: Larger than black ants, carpenter ants range from 0.25 to 0.5 inches in length. -
Color: Typically black, but some species appear reddish or orange.
-
Behavior: Carpenter ants excavate wood to create nests, which can weaken the home’s structure.
-
Damage: Carpenter ants do not feed on wood. They hollow it out, leaving smooth tunnels and galleries that may compromise wooden structures.
Black Ants
-
Size: Smaller than carpenter ants, black ants range from 0.1 to 0.3 inches in length.
-
Color: Typically black or very dark brown.
-
Behavior: Black ants search for food and prefer sugary substances. They do not excavate wood or cause structural damage.
-
Damage: Black ants are a nuisance pest but do not cause structural damage to your home.
Do Carpenter Ants Bite?
Carpenter ants are capable of biting, but they typically do so only when they feel threatened. Their bites are not venomous but may cause mild irritation, redness, or swelling for some individuals. During a bite, carpenter ants may also release formic acid, which can intensify the irritation on the skin. While carpenter ant bites are generally harmless to humans, the real concern lies in their ability to damage a home’s structure. Carpenter ants hollow out wooden beams, floors, and walls to create their nests, potentially compromising the integrity of the affected wood over time.What Damage Do Carpenter Ants Cause?
Carpenter ants can be considered a huge threat to homes as they excavate wooden beams, joists, and walls to create nesting galleries. Unlike termites, they don’t consume wood but carve through it, gradually compromising the strength of wooden structures. Over time, this can weaken key support elements like beams and floors, increasing the risk of warping, sagging, or collapsing.

How to Get Rid of Black Ants?
Black ants are more of a nuisance than a threat, but they can be difficult to get rid of. Here are some effective DIY methods for black ant control:Tips to Prevent and Control Black Ants
- Seal Entry Points: Inspect your home for entry points like cracks in walls, gaps around windows, and door frames.
- Clean Up Food Sources: Black ants are attracted to food. Clean up crumbs, spills, and trash regularly, especially in kitchens and dining areas.
- Use Ant Baits: Place ant bait traps in areas where you see black ants. The ants may take the poisoned bait back to the colony, eventually killing the queen and other ants.
- Natural Remedies: Natural repellents like vinegar, lemon juice, and cinnamon can help deter black ants. Spray these substances along entry points and areas where ants are active.
How to Get Rid of Carpenter Ants?
Unlike black ants, carpenter ants pose a structural threat. To protect your home, you must act quickly if you spot them. Here’s how to control a carpenter ant infestation on your own:Steps to Eliminate Carpenter Ants
-
Locate the Nest: Look for frass (wood shavings), hollow-sounding wood, or rustling noises behind walls. Carpenter ants often nest in moist or water-damaged wood.
-
Seal Cracks and Gaps: Use caulk to seal cracks in your home’s foundation, windows, doors, and other entry points to prevent ants.
-
Remove Moisture Sources: Fix plumbing leaks, improve ventilation, and eliminate excess moisture in basements, crawl spaces, and attics to deter ants.
-
Use Ant Bait and Pesticides: Bait traps kill colonies by targeting nests. Spray pesticides around entry points and areas where carpenter ants are seen.
