Unlike other termites, the Drywood termite does not need the moisture found in soil to survive. Instead it establishes its nest completely above ground in dry, undecayed wood.
Know Your Enemy!
Signs of Drywood Termite Infestation:
1. Shed wings
2. Ejected wood pellets
3. Galleries inside wood
4. Piles of fecal pellets outside wood galleries which are elongated (approx .03" long) and round on the ends, with six flattened surfaces
(More detailed instructions for home inspection are available at Do Your Own Termite Inspection at Home. This article specifies Subterranean termite inspection, but its methods work for Drywood Termites as well.)
Recommended Treatments for Drywood Termite Control:
1. Structural fumigation (for severe infestations) can be very effective, but must be performed by a certified pest control operator. The entire structure or building is tightly covered with a special cover, after which a sulfuryl fluoride or methyl bromide gas is fumigated.
2. Spot Treatments. Spot treatments of infested wood may be accomplished by drilling a hole directly through the infested timbers and into the termite gallery using a 1/2" drill, or smaller depending on timber size. An appropriate liquid, such as Boracare or Timbor may then be injected into the galleries. Dusts should always be injected in small amounts, as too much will cause the termites to damn off the gallery and move elsewhere.
3. Wood Treatments. Treat infested wood directly with a insecticide borate preservative such as Timbor or Boracare. These products are also a great preventative treatment for wood that is not yet infested. You can find out more about wood treatments at the following link: How To use Timbor, and by closely following the instructions found on the product label.
4. Infested Furniture- You will have great success using a wood insecticide and preservative such as Boracare or Timbor. If the furniture is painted, sealed, or varnished, it will need to be stripped bare before using these products. The chemical that you choose should be sprayed directly to the infested surface and allowed to penetrate the wood. (Always read the product label for specific instruction before application). The treatment should kill all active termites or beetles and last the life of the wood.
