Carpenter ants are one of the most commonly identified types of ants in North America. They are social insects that live in colonies and build elaborate nesting sites in wood. Carpenter ants can cause damage to wooden structures as they enlarge their nests. Knowing the signs of an infestation and how to control them is important for protecting your property.
Carpenter ants are quite large in size, usually between 5 and 25 mm (1/4 to 1 inch) in length depending on the species. They can range in color from black to red and black, to yellow and black.
Carpenter ants are often described as having a solid black waist between the thorax and abdomen. This characteristic allows them to be easily distinguished from other ant species. Carpenter ants also move slowly and can often be found moving across walls or along branches outdoors.
Carpenter ants build their nests in moist, soft wood, taking advantage of any existing cracks or crevices. The most common nesting sites for carpenter ants are found in roof eaves and around windows. They can also be found in exterior walls, attics, and crawl spaces.
It is estimated that carpenter ants cause around $5 billion in damages in the United States every year. Even though they don’t actually eat wood, they can significantly weaken wooden structures by excavating gallery systems in order to build their nests.
In order to determine whether or not your home or property is infested with carpenter ants, look out for the following signs:
- Presence of sawdust or small piles of wood chips around the affected area.
- Rustling or tapping noises coming from walls or ceilings.
- Presence of large, winged ants in or around your home.
- Sightings of carpenter ants in the daytime.
Experts suggest that the most effective way to control a carpenter ant infestation is to locate and remove the ant colony. This can be difficult as ant colonies can have multiple nests. However, certain chemical treatments and insecticides can also be used to eliminate the infestation. It is important to keep wood surfaces around your home dry, as well as replace any weak or rotten wood.
Prevention Measures
Implementing preventive measures is the best way to avoid an infestation of carpenter ants at your home or property. Here are some tips to help you prevent carpenter ants:
- Regularly inspect your home for cracks or openings in the walls or roofs, and seal any findings.
- Maintain good drainage around your home to prevent water-logging.
- Maintain a clean and tidy environment around your home, this includes regularly disposing of any accumulated scrap or junk, like old stumps and logs.
- Trim any trees and shrubs around your home regularly, to prevent any ant nests from forming.
- Keep wooden surfaces and furniture dry, to prevent moist wood from developing.
Carpenter Ant vs Termite
Carpenter ants and termites can often be confused, as both these insects cause damage to wooden structures. The most obvious difference is their size, as carpenter ants are usually 5-25 mm in length, while termites can grow up to 35 mm in length.
Termites have a stockier body and straight antennae, while carpenter ants have a thin waist and elbowed antennae. Carpenter ants do not actually eat the wood, instead they excavate the wood in order to build their nests. Termites however eat the wood, digesting the cellulose to obtain nutrition.
The Life Cycle Of Carpenter Ants
Carpenter ants live in complex colonies and have a complex life cycle. The members of the colony are divided into castes, including workers, soldiers, and reproductive individuals. The queen ant lays eggs which are then incubated and cared for by the worker ants. After hatching, the pupate develops into an adult ant and the life cycle is complete.
The reproductive individuals of the colony are the swarmers or alates, which possess wings and are capable of flight. Swarmers are usually observed during the spring or summer and are responsible for mating and starting new colonies.
Management and Control
If you suspect that your home or property may be infested with carpenter ants, it is important to contact a professional pest control expert. An experienced pest control expert will be able to identify the infestation and determine the best treatment for the situation.
For an infestation that is limited to one area, you may be able to treat the problem yourself with an insecticide or other pest control product. However, for an infestation that has spread throughout the structure, it is best to consult with a professional. Professional services can also help in preventing future infestations and protecting your property from any type of damage.
Health Risks
Carpenter ants do not directly cause any human health problems, but they can spread germs and diseases like salmonella and E. coli. This is why it is important to address an infestation as soon as possible to prevent any serious health risks.
Carpenter ants also produce some allergens that can trigger allergic reactions in humans, such as sneezing, coughing, and watery eyes. Some people may be particularly sensitive to carpenter ant allergens and should take precautions to avoid further exposure.
Cost Of Treatment
The cost of treating an infestation of carpenter ants can vary depending on the severity of the infestation and the size of the affected area. For example, a small infestation may require only a single chemical treatment at a cost of around $100. A large infestation may require multiple treatments and can cost up to several hundred dollars.
In addition to the cost of the chemical treatment, there may also be additional fees for pest control services, such as inspection or removal of the nest. It is important to research local professionals and compare their prices and services before deciding on a pest control company.
