Signs of Carpenter Ants in Your House & What To Do
Published Date: April 7, 2023
Identifying carpenter ants early in your home could become the difference between a structurally compromised and a sturdy home. Carpenter ants can weaken your home’s structural integrity and cost you dearly on home repairs if you don’t act upon it soon. This article enlightens you on the signs of carpenter ants in your house for your quick action.
Carpenter ants are some of the country’s largest and most destructive ant species. They’re fairly large and usually burrow in wood to create their nests, thus creating voids that affect their structural integrity. Read on to understand these species and how to mitigate their damage to your home through early identification.
Easy Ways to Identify Carpenter Ants
Carpenter ants are fairly large and could measure up to 12mm for worker ants and 20mm for the queens. The average size is about 18mm. Their name comes from their unique carpentry when burrowing through the wood to build smooth tunnels for their nests. They rarely nibble on the wood in which they build their nests. Instead, they forage around the house for food.
You may notice worker ants around the house, foraging for food and building their nests. They prefer wet wood because of the ease of burrowing through weakened wooden material. Also, decayed or damaged wood makes brilliant homes for these ants. It’s the perfect habitat to breed their eggs until they mature into larvae and adult ants.
The insulation they tunnel through can sometimes be frass. Looking closely, you may see that the wood has tiny pinholes. Carpenter ants create these tiny holes when they burrow through the wood in order to force the frass out and continue their tunneling.
Some might easily confuse them with the usual household ants. But they’re bigger than regular household ants and often leave around sawdust as they burrow through the wood. Once you spot these ants in your house, you can easily follow their trail to identify their nest.
Carpenter ants have three body parts (head, thorax, and abdomen), usually black and red. Most have a black abdomen, while the head and thorax combine the two colors.
What Does a Carpenter Ant Nest Look Like
Carpenter ants prefer building their nests in decaying or moist hardwoods and trees. They prefer those with holes where they can get in and out easily while foraging or moving around. These types of wood provide steady temperature and humidity, more so when wet, where they can thrive and grow their colony.
As they burrow through the wood and trees, they’ll push out the sawdust or frass, a subtle sign of their nest’s location. Parent colonies that host the queen and the eggs are always in damp areas, probably areas with plumbing issues or near your kitchen sink or basement.
Satellite colonies can thrive even in dry conditions because they only have workers, pupae, and larvae. The smooth tunnels in the wood structure present a comfortable yet artistic way of carving out their habitat within pieces of wood and trees in your home structure. The voids created might harm your home’s structural integrity and strength, costing you money during repairs.
Carpenter Ants vs. Termites
Carpenter ants differ from termites as they don’t feed on wood. They only create tunnels and pave the way for their nests. Termites are more destructive than the former.
However, the appearance and behavior are quite similar except for the waist, antennae, and the wings in winged termites. Winged termites have equal lengths of wings, while carpenter wings have longer front pairs of wings.
Carpenter Ants vs. Black Ants
Black ants differ from carpenter ants in their body shape. The former has two irregular or bumpy nodes between the head and the thorax. While carpenter ants have single round parts as you approach the thorax.
Carpenter ants are larger and have heart-shaped heads. In contrast, black ants are small and have round heads.
Signs of Carpenter Ant Damage & Infestations
Homeowners must be keen to identify ant infestations early enough to deal with them effectively. Failure to curb the infestations early might force you to incur thousands or millions of dollars in repairs or reinstallations of critical areas within the home due to structural damage. Here are some warning signs to watch out for
If you see carpenter ants around your house, then there’s probably an ant’s nest within the home. Seeing large black ants around the house could also indicate the presence of carpenter ants.
Carpenter ants usually leave trails of dust when burrowing through the wood. They push away the sawdust and shavings when creating their nests and tunnels in the wood. Check out for small stashes of sawdust on the floor or wall near wooden structures. Infested structures could include the attic, door frames, chimneys, cabinets, or window sills around the house.
If you notice a swarm of winged carpenter ants around the ceilings and walls, it’s a sure sign of infestation. Colonies of winged or flying ants are a common spectacle during spring when reproducing. They’ll hop onto other nests and colonies to produce new colonies. You must call in experts to identify their nests before they wreck more wood structure damage.
If you commonly find shredded ant wings around the house while cleaning, you might host a large colony of ants. Check out vents or window sills for these wings showing signs of mature ant colonies ready to reproduce. Call pest infestation experts to examine your home for colonies or swarms.
5.Rustling Sounds in Walls:
As the carpenter ant colony grows, they must expand their nest. A large colony of more than 10000 worker ants produces ruffling sounds when working on the nest. If you listen in closely, especially at night when it’s quiet, you might hear shuffling sounds indicating their presence. Move quickly to identify the sound’s source. Let an expert examine and deal with the infestation.
Fecal droppings are a sure sign of ant colonies in your home. You’ll likely be hosting mature worker ants or their pupae which might cause extreme damage if not promptly handled.
Look out for this fecal matter that’s usually bound together with the frass from burrowing around walls, ceilings, or leaderboards. The ants will typically chew and excrete the wood while creating their nest.
Worker ants always stray away from the nest, looking for food. A trail of ants around the house indicates the presence of a colony. Worker ants don’t forage more than 300 feet from their nest. When you see them, know their nest is nearby or within your home. You can easily follow their trail back to the nests to identify the damaged wood and infestation area.
Once ants burrow and tunnel your wooden structures, they’ll leave voids. You have hollow and lighter wooden pieces. When you knock or hit them, they’ll produce an open sound indicating the presence of tunnels (that host their nests).
Regular checkup of the pieces of wood or stumps around the house gives you a good headstart when dealing with carpenter ants. They like living in hollow, decayed, or isolated parts of the wood.
How to Get Rid of Carpenter Ants:
You can use various methods to treat and prevent carpenter ants' infestation. Check out these proven ways to get rid of these ants.
- Set Up a Bait for the Ants: Carpenter ants get attracted to sugary scents and food. Set up a shallow tray or bowl with water. Then, mix sugar and baking soda in a small tin and place them at the center of the bowl. The ants will drown in the water as they follow the sugar scent.Also, you can use color to follow their trail back to the nest. It helps you identify their nest easily. Place a jar of jelly or sweets and allow it to leave a trail as it returns to the nest. Then you can destroy the nest to get rid of them.
- Destroy Their Nest: Destroying their nests prevents further damage to your home. Find out where the nest is and blow or spray in chemicals like boric acid or by removing the wasted wood. However, it might be easier to remove with professional help.
- Clean Up Their Trails: Ensure you clean your house and remove stumps, branches, and other pieces of wood around the house. Ants follow the scent trail they leave behind while foraging for food. Eliminating this scent disrupts their flow. When they can't find their way home, they'll soon disperse, and their numbers will dwindle and die out.Removing wood around your compound eliminates potential breeding and living places. Such wood around the house gives them the perfect environment to set up their habitat. Pools of water with the wood allow them to thrive and grow exponentially.
- Use Insecticides: Chemical treatments are quite effective when killing ants. Consult the pros on which insecticide to use and spray around the house. You don't need to locate the nest for its effectiveness.
- When to Call in the Pros: Call exterminators immediately if you notice carpenter ants or their nests in your home. You can use the mentioned methods of dealing with these pests, like destroying their nests or using insecticides to eliminate them.You'd better call a pro if you didn't do comprehensive work when applying these methods. Pest infestation experts will scan the area for unidentified nests or if you need to destroy the current nest effectively. They'll help you devise preventive measures to keep them off your property.
