Do it Yourself Drywood Termite Control

Drywood termites are different from the more familiar damp wood termites. Unlike the damp wood termites, which live in moist soil conditions and need a connection to the soil, drywood termites need very little water, do not live in the soil and can live in harsh climates. According to Do It Yourself Termite Control, they infest dry and non-rotting wood common in building structural supports, and they are often found in attics. The most common habitat for the termites is subtropical and coastal regions like California, Florida and Texas. When an infestation occurs, there are several treatment options.

Drywood termites do not eat rotting wood; instead, they eat dry woods.
  1. Find out whether the termites are drywood termites or damp wood termites. Look for galleries in wood, pellet droppings and wings that are shed--all common signs of drywood termites. Examine pellets; drywood termites have flattened and depressed regions on the pellets while damp wood termites do not.

  2. Use a liquid aerosol on a limited infestation. Inject the liquid aerosol into the wood with the needle that comes with the aerosol. The result is rotting wood and weaknesses in the wood. The drywood termites do not eat rotten wood, so they will either leave or they be poisoned before the rot takes root.

  3. Drill a few holes in the wood and then pour aerosol dust into the wood. Aerosol dust will kill the termites, but the dust does not start rotting the wood. Instead, holes are drilled into the wood and then the dust is poured onto the food source to kill the termites. Aerosol dust works best on small and limited infestations.

  4. Apply heat to the wood. Depending on the wood, heating methods will differ. Use a heater to bring the wood up to a lethal heat in a localized area. Heating the wood is limited because if the wood does not reach 120 degrees Fahrenheit, is not heated completely through or some wood is missed, the termites will survive. Heating is best for small infestations that have not yet spread to the house because heating all of the wood in the house to lethal temperatures is not practical.


  • Large infestations that are no longer localized to one small area require fumigation. In the case of fumigation, a professional should exterminate the termites.
