When you see the presence of some foraging ants in your home; 1 or 2 winged "queens" during the swarming season does NOT mean you have an infestation in your home.

Foraging ants have been observed entering homes along phone lines, tree branches and even trails in the ground. This can indicate the house is a nesting area. If ants are coming in, there may be a nest outside the house and eventually there maybe a satellite colonie(s) established at some portion(s) of the house. It is important to make sure they are not moisture ants, termites or yellow jackets. Some, like carpenter ants, are important because they damage building materials. And some ants only become pests when they enter homes in search of food and water.
The Evidence Of Carpenter Ants:

An occasional ant may scout out looking for food sources, and this may not indicate the presence of a nest, however continuous / numerous ants are a sign of likely nesting that is likely occurring.

Sawdust: when accumulating in piles or caught in spider webbing has a very finely shredded appearance. (IMPORTANT NOTE: Not to be confused with small sawdust from construction activity).
The Common Type Of House That Has Carpenter Ants:

Wood Frame
Houses with crawlspaces
Cedar or plywood siding
Moderately to gently sloping roofs
Houses from 5-25 years of age
Houses with vegetation close and around the house.
Houses located near the edge of a forest are more prone, due to already established nests in trees and forest vegetation areas

Most Likely Nests Locations In Order Of Frequency:

Outside walls and voids-35%
Attics- 21%
Ceilings- 19%
Crawlspaces- 19%

What Do Carpenter Ants Eat?

Carpenter ants do not eat solid foods, as they have a very small and narrow food pipe.
Mostly carpenter ants gather aphid honeydew or tree sap.Candy residue, syrup, soda pop, apples, raisins, once soggy.

Managing Carpenter Ants:

Finding the parent colony in the landscape around the house is critical for BEST control results!!.
Many Pest Control specialists will drill and inject the entire house, and feel that they can do this at a lower cost than to locate and treat the nest areas.
Other Pest control specialists are of the opinion they can starve out the ants by spraying only the perimeter, (attic, crawlspace and foundation areas), at monthly intervals for a year.
