Chipmunks: Identification & Lifestyle | Chipmunks Control Services

One of the most common house ants in the United States is called the Carpenter ant, which is in the habit of nesting in wooden buildings. Carpenter ants often confuse them with termites, as their habits and mode of destroying wood are different in many instances. The first step to effective Carpenter Ant control & understanding their nesting behaviour, appearance and prevention methods.

What Are Carpenter Ants?

Carpenter ants are large ants, commonly half the size of an ant. They may be black, red, or both. Carpenter ants do not use wood as food, as do termites. Instead, they excavate it to nest in it. These ants love damp or rotting wood, as it is easier to tunnel.

They are very common in places like window frames, decking, attics or wood beams – especially where these areas have been exposed to some sort of moisture. They can cause serious structural problems, but the perforation of the wood may take time before it is detected, and their behaviour is used to nest.

Carpenter Ant vs. Termite: Spot the Difference

Carpenter ants and termites destroy wood. They do so in completely different ways. You can differentiate between the two of them easily: 

  • Look: Carpenter ants have a narrow waist, bent antennae, and their wings are not the same size. But on the other hand, termites have straight antennae, a thick waist, & their wings are of the same size. 
  • Behaviour: Carpenter ants do not eat wood, while termites consume wood as their food.
  • Nesting: Termites remain deeply set in wooden structures and are therefore harder to see. Carpenter ants normally begin nesting in moist or rotting wood and then relocate to arid regions.

Having such differences will enable the homeowners to make the right move towards Carpenter Ant Control before the situation deteriorates further.

Wood Nesting Habits of Carpenter Ants

Carpenter ants like to nest in soft, moist or decaying wood. In the woods, they excavate smooth tunnels and galleries where their colonies are to be found. So perfectly turned are these tunnels that they frequently appear smooth or rubbed.

Colonies are of two types:

  • Parent colonies are located outside of dead trees, logs, or stumps.
  • Satellite colonies, which are either placed on the wall of the home, roofs or inside beams.

After the satellite colony is built indoors, the ants may grow and reproduce, and this complicates the process of Carpenter Ant Control. The greater the time they spend in your home, the more damage they will inflict on the structure.

Signs of Carpenter Ant Infestation

Early detection of an infestation of carpenter ants would save you big costs in repairs. Look out for these signs:

  • Little heaps of sawdust-like substance (so-called frass) around wood buildings.
  • Scampering or knocking in walls or wooden structures.
  • Huge winged ants that hatch out in the home, particularly in spring or early summer.
  • Wood that sounds hollow when tapped.

When you see any of these signs, you should immediately contact a professional Carpenter Ants treatment to make sure that they are present.

How Carpenter Ants Damage Structures

Carpenter ants do not eat wood like termites; their nesting habits are still able to destroy a home. Their tunnels make the pillars made with wood, surface weak.

The structure may not seem damaged, but over time it may become unstable. That can result in expensive repairs in case it is not done timely manner. House owners in the wet or rainy regions of the United States are particularly vulnerable since ants are attracted to moisture.

Early Carpenter Ant Control is very necessary to avoid the further spreading of the ants and loss of greater damage.

Appearance and Identification

Early prevention is important in identifying carpenter ants. Here’s how to recognise them:

  • Size: Commonly bigger than the common house ants.
  • Colour: Black, red or reddish-black.
  • Shape: Obvious slenderness between the thorax and the abdomen.
  • Wings: The winged carpenter ants are confused with termites except that the front wings are longer than the back wings.

These ants are nocturnal and they forage food, including sweets, meats or pet food. When you see big ants roaming around at night, you will know that you will need Carpenter Ant Treatment in the near future.

Prevention and Control Tips

To prevent carpenter ants near your home, the maintenance habits that are necessary are simple. Here is what you can do:

  1. Get rid of Moisture: Fix leak pipes, roofs and drains. The carpenter ants will be attracted by moist wood.
  2. Seal Entry Points: Small holes, gaps, and openings around the entry points and windows.
  3. Clip Bushes and Trees: Do not have the branches close to your house because ants can use them to enter inside.
  4. Stoke Firewood: Store piles of firewood outside of your house and off the ground.
  5. Periodic Inspection: Handle routine pest checks in a short period of time in order to catch early infestations.

These are excellent preventative measures, though in case of a severe infestation, it is always safe and effective to resort to professional Carpenter Ant Treatment.
