Structural fumigation is a treatment technique used to control drywood termite infestations in a home. This treatment method should be used only when the infestation is too extensive, too difficult to locate or too difficult to access with more targeted methods.
If your pest control professional discovers signs of drywood termites in your home during an annual termite inspection, he or she can discuss options for controlling the infestation, including structural fumigation.
Unlike annual termite inspections, you do not need to fumigate for termites yearly or at any other scheduled interval after the active colonies have been controlled. However, after fumigation, it is important to continue to receive annual inspections to identify signs of infestations as soon as possible. Fumigation leaves no residue that can help prevent future reinfestation by drywood termites.
Tips to Prevent Drywood Termite Infestations
A drywood termite infestation begins with a king and queen that slip into a crack in the wood of a home, excavate a little “nuptial” nest and seal themselves inside. To help prevent an infestation, you can use protective wood treatments and regular home maintenance, including the following activities:
- Seal all cracks, crevices and joints on the exterior of your home.
- Add a fresh coat of paint to exterior wood when it begins to peel or bubble.
- Keep screens on attic and foundation vents.
- Get rid of any materials that might house termites in your yard, including dead trees and lumber. Store firewood far away from your home to avoid easy access.
