Drywood Termite Control

Control measures include reducing the potential for drywood termite infestations, preventing termite entry, removal of infested wood and applying chemicals for remedial treatment.

Inspection

Thorough inspections are necessary to confirm termite infestations, assess the extent of damage and determine whether remedial control measures are necessary. Reliable insect identification is imperative.

When inspecting for drywood termites, carefully examine the exterior of the house, particularly the eaves (1) or any wooden siding (2) or exterior trim (3). Carefully check corners or under the eaves for spider webs that may contain fecal pellets. Check window and doorframes (4), sills, roof eaves and exposed ends of rafters (5). Examine and sound porch roofs (6) and supports (7), stair carriages and trellises. Open any exterior electrical meter or fuse boxes set into walls and examine them for fecal pellets. Sound and probe wooden roof shingles (8) and any projection to the roof such as dormers, cornices or wood trim. The ends of shingles at roof eaves are the most common places for infestation.

Indoors, carefully examine your home in a room-by-room basis, overlooking no area. Examine door and window frames and trim for damage. Closely examine the baseboards on the perimeter walls, particularly if you have wood flooring. Check windowsills for fecal pellets or discarded wings. Exposed beams and wooden paneling should be examined thoroughly, as well as places that are continually warm such as near water heaters and furnaces. Drywood termite damage seldom can be observed on the wood surface; however, sometimes painted wooden surfaces will look blistered if termites have tunneled close to the surface. A sign of advanced infestation is surface blistering that can be probed with a sharp screwdriver.

Treatment

There are several alternatives for dealing with drywood termite infestations or damage, depending on the extent of the problem. This places great importance on an extremely accurate inspection of the structure.

No Control

Where the infestation is slight or damage is cosmetic and limited to one or two small areas, you may choose not to use any control measures. Drywood termite colonies often develop slowly; therefore, the costs incurred with some control measures may not be warranted. But if you choose not to control, be sure to maintain a monitoring program so you’ll know when and if control becomes necessary.

Wood Replacement. Where the infestation is limited, remove and replace damaged wood, preferably with pressure-treated or Bora-Care wood that will protect against both termites and wood decay. Or it may be more practical to have a pest control operator apply special formulations of wood preservatives. They penetrate fairly deeply into unpainted wood surfaces, particularly cut ends and structural joints. Certain precautions are necessary to protect ceilings and painted surfaces from staining.

Localized Treatments

There are many localized/spot treatment methods available for the removal and further prevention of drywood termites. One option is injecting an aerosol insecticide, such as Invader HPX or PT-565. Foaming the gallery with the Chapin Foamer and Timbor or Premise 2 is a very common practice for professionals. Another treatment method is to apply a dust into the gallery using Borid Turbo or Timbor. Injecting the gallery with Jecta after one of these initial treatment methods will completely eliminate the colony and protect the surrounding wood for years to come. After treatment of the existing gallery, application of Bora-Care, Jecta or Impel Rods will prevent any further infestation for the life of the home.

Treating as many wood members with Timbor or Bora-Care, especially in critical areas will ensure that there is no future infestation of drywood termites.

Our Drywood Termite Kit, will help you knock out the colony and protect the wood from re-infestation.
