Appearance: Swarmers (seen most often) are dark-colored, about 3/8” long, have two pairs of gauzy wings of equal length and have a straight-waist as opposed to an ant’s wasp-like pinched waist. Workers (responsible for damage) are whitish, soft-bodied and are about ¼” in length.
Evidence of: Swarmers (generally seen in Feb., mar. or April), mud-tubes on foundation walls, wood members with excavated tunnels (having dirt-like deposits in them) and sagging walls/floors due to structural damage.
Control method: Exterior bait stations are installed around the perimeter of the structure(s) approx. every 10’ and any interior areas where termites are present, receive localized- treatment. Two-year baiting programs are standard, comprised of an initial installation/treatment followed-up by quarterly visits. Nordstrom Pest recommends a quarterly monitoring service, following the two year baiting program. Pre-construction treatment may be desired in susceptible areas and may actually be required in some instances.
