Carpenter Ants

Camponotus pennsylvanicus

Recognition: Large, upwards of ½" in length. Mainly reddish-brown to black.

Bio: Carpenter ant colonies can grow to as large as 50,000 workers. Colonies will initially establish themselves in moist decaying wood before expanding into dryer, healthier wood. Workers will excavate a gallery large enough to support the colony, leaving behind sawdust and frass. 

Control: As with all pests, Abair Lavery will take the least hazardous approach possible. Where wood is clearly moist, drying out the wood or replacing it may be necessary. An exterior perimeter treatment is highly effective. Where infestations have become severe, an interior treatment using residual liquids or gel baits may be required.


Pharaoh Ants

Monomorium pharoaonis

Recognition:Workers monomorphic/ Roughly 1/16". Queens generally twice the size of the workers. Off white to yellow in color.

Habits: Colonies are generally large with up to several hundred-thousand workers. The colony is subject to a process called "budding" due to the fact each colony will have multiple queens present. Each queen has the ability to branch off and form a separate colony.

Control: As with all pests, Abair Lavery will take the least hazardous approach possible. A thorough inspection will be performed to determine possible colony locations. Because of this ant’s biology, baiting techniques are the only method used. Using dusts and/or liquid sprays will only make the issue worse as repellents cause this particular species to fracture into separate colonies, thus making control more difficult.


Odorous House Ants

Tapinoma Sessile

Recognition: Workers monomorphic measuring roughly 1/12". Body is brown to black.

Habits: Colonies can reach upwards of 100,000 ants, but rarely do so. This ant has habits that are similar to what you find with Pharaoh ants. Each colony will have multiple queens and satellite colonies usually form. This particular ant may change nest locations regularly making treatment difficult.

Control:As with all pests, Abair Lavery will take the least hazardous approach possible. Home owners should make no attempt to control this ant on their own. Liquid applications alone will not solve the issue. This is a sweet feeding ant and complete control may require multiple visits to apply the appropriate baits.
