 Species and Nesting

These pests are the most common wood destroyer that we deal with in Oregon. There are three species of carpenter ants in Oregon and they are: Modoc, Vicinus and Essigi. Carpenter ants will vary in size and color. For instance, the Modoc is all black and will range from ¼" to 1" in length. Vicinus ants are approximately that same size but will have a reddish brown color in the middle section of its body. The Essigi is the smallest of the carpenter ants and range from ⅛" to ¼" inch in size and will also have a reddish brown color in the middle section. It’s important to identify what type of carpenter ant you have because the treatment can vary from species to species. Primary colonies will be located in damp or wet areas in or around your home. If you have had leaks in the bathroom, kitchen or roof, this could be a prime location for a new colony. Tree stumps or RxR ties at the exterior of your home are also great locations for colonies. Modoc and Vicinus will tend to nest in the exterior wall voids or the crawlspace, and the Essigi are most likely to nest in the attic or the roof itself.


The way in which carpenter ants expand their colonies, once the queen has reached maturity, is that she will produce winged reproductive male and female ants which will fly or swarm in the spring time. These kings and queens will mate one time then the new fertilized queens will find a place to start their new colonies. Once she finds a suitable location she will lay a few eggs and care for them until they hatch. Next, these few workers will forage for food, care for the queen and start to excavate for the new colony. This colony will continue to expand and make satellite colonies which is the most common nest found in homes, until this colony's queen reaches maturity which can take from 4-8 years and she will then send off her winged reproductive. Modoc and Vicinus colonies will range in the tens of thousands of workers in the primary and satellite colonies.


Carpenter ants will mostly forage at night but it is still possible to see a few during the day if a colony is in need of food. When carpenters ants forage they leave a scent path which the others can follow, this is how they can travel up to 300 feet, in some cases, from the colony. There are many things to look for when hunting carpenter ants, the first being dead ants in spider webs and also any sawdust or frass that may be as a result of an ant infestation. The biggest misconception is that carpenter ants eat wood and they do not, they just bore it out to make galleries. Now If you think that you have an infestation then please call us.
