Carpenter Ants, Carpenter Ants….HELP!

Nesting Behavior: Carpenter ants in the East generally have smaller parent nests in deciduous trees. Satellites in Structures: Carpenter ants are attracted to the soft, easy-to-chew wood used to build most houses, making structures ideal for satellite colonies. These usually are found in the attic, crawl space or subfloor where ants have access to the outside. The presence of winged ants indoors in early spring is a good indication that the structure has a satellite colony.Workers Move In: All Carpenter ant workers come from the parent colony. They move into the satellite colony in summer and, once established, may stay there for a long period. The satellite colony must have worker reinforcements from the parent colony or it will die out.Reproductives Move Out: Satellite colonies commonly contain winged male and female reproductives. These ants do not add to the satellite colony population; they will fly off to start the next colony. Satellite colonies usually do not contain a queen and do not reproduce unless workers are reproducing males.Food Preferences: Carpenter ants don’t eat wood, they nest in it. They are omnivores, feasting on caterpillars, honeydew and their favorite — aphids and other hemopterans. Occasionally, warm indoor temperatures will interrupt the ants’ winter dormancy, and homeowners will find them seeking moisture in sinks or getting an early spring sugar fix on donuts or fruit.Vegetation Must Go: Carpenter antsmust go outside to feed, so PMPs should inspect vegetation and ensure none touches the structure. This includes branches that may scrape the roof during heavy snow or rain. Check the Wires: The ants also will walk wires into structures, so carefully inspect cable/Internet lines. Some lines go through trees, making for a perfect way in and out.Keep Wood Dry: Moisture weakens wood siding — which, in turn, attracts Carpenter ants — so take steps to keep it dry. Grade the foundation so water runs away from the structure, and keep the area clear so snow build up and splashing rain won’t compromise the siding. Never let wood come in contact with the soil.Pay Attention to Birds: Woodpeckers drum in the spring to call for mates, but they also peck holes in houses to get to carpenter ants — a chief food source. If a homeowner has woodpecker issues year round, consider removing the siding in key spots: You may uncover an ant problem.Get the History: Buried wood is highly conducive to carpenter ants, so interview clients about their yards. Are stumps or timbers buried on the property? What’s under the bark and landscape plastic in the flower beds? They may not know but it’s worth asking.
