Unlike dampwood or subterranean termites, drywood termites don’t need a constant moisture source to flourish. These termites swarm (generally in the spring time) and can fly into any crack or crevice in your home to start their colony. A drywood termite infestation can survive in the attic, sub-area, roof sheathing, rafter tails, and also in windows, windows trim, internal framing, etc.
Drywood termites excrete fecal pellets that resemble saw dust or sand that they push through an exit hole in the wood members. Piles of these pellets are generally how an infestation is discovered. If an infestation is limited, a localized treatment may be effective.
Drywood Termites Treatment
Omega Termite and Pest Control generally uses a product called Termidor Termiticide which we have found to be very effective in treating a localized drywood termite infestation. Orange Oil, which is a reduced risk insecticide, is less toxic than Termidor, but not nearly as effective at eliminating a drywood termite infestation. Termidor is odorless and injected directly into a drywood termite gallery.
It is extremely difficult to determine the full extent of a drywood termite infestation since drywood termites can live in the internal framing and may not be fully detectable. An inspector may find termites that are visible, but may not be able to determine the full extent of the infestation.
A fumigation of the entire home with Vikane gas is often warranted if the infestation extends into inaccessible spaces. The fumigant penetrates deep into all of the wood members of the house and is very effective at eliminating termites -- not only the visible infestation but any hidden drywood termites as well. This process is highly regulated by the State of California and poses little to no risk to the homeowner. Omega Termite and Pest Control has never had a health related complaint as a result of any fumigation we have performed.
