Carpenter Ants

Carpenter ants are 1/8 to ½ inch long. Carpenter ants are easily distinguishable due to their wings. They can produce sawdust inside the home causing damage to structural boards to your property.  If you find these ants in your home, you need the help of an experienced St. Louis Ant Exterminator right away.


Most Carpenter ants establish their nest in decayed wood, later expanding into sound wood. Trees, wall voids, insulation, and moisture issues will attract these pests to your property. They will feed on insect honeydew, plant and fruit juices, insects, and other arthropods. Inside food sources could be sweets, eggs, meats, cakes, and grease. Worker carpenter ants will forage up to 300 feet from their nest. Often, workers are found inside the home in kitchen, baths, or other sources of moisture. They begin trailing just like small ants, however they are primarily on the move from dusk until dawn. Overhead utility lines will lead them right into your home and into soffits, gutter lines, and attics.

Damage and Signs of Infestation:

Exterior indication of the presence of Carpenter Ants can include wood shavings found around tree bases or pieces of insect parts found mixed with insulation being kicked out of cracks & crevices. Windows or doors missing caulk can allow them access inside the walls of the home. Once inside, the ants will continue to forage around seeking moisture to keep their colony thriving. An experienced St. Louis Ant Exterminator can help identify signs of Carpenter Ants and find their entry point into your home.


Inspection is the key to successful control. Treatment for these insects needs to be reapplied in order to make sure these ants don’t return to your home. Areas to be treated will be attics, pipe chases, window frames, entry points, and exterior bases of trees. With Carpenter Ant control the St Louis Exterminator needs to turn their backs from the property. We call that ‘thinking like an ant’. Locating trailing will often bring the exterminator into the nesting site. Nests located inside wall voids need to be drilled and treated with a dust or aerosol product. Bait can be placed out for the foraging ants as well. A full perimeter liquid treatment around all areas, wood piles, stumps, windows, doors, foundation, cracks & crevices is generally recommended.
