Drywood Termite Control

While many west coast homeowners are subject to subterranean termite infestations, residents of Florida are often victims of drywood termites. There are many options for drywood termite control, all with distinct advantages and disadvantages. When facing an infestation, it is important to know the facts about drywood termite control.


Fumigation, (or tenting) is the only method used that insures the complete eradication of all drywood termites in your structure. Before fumigation, your home is covered by a gas-tight tarpaulin, which essentially creates a gas-tight structure for the fumigant to fill. While incredibly effective, there are some draw-backs to this procedure.

The home must be prepared by putting all food and food items into special protective bags, all animals and plants must be removed, and overnight evacuation is necessary. You are not approved to re-enter your home until your home has been aerated and tested for the presence of fumigants. While this process is certainly inconvenient, many people feel it is worth the trouble.

Heat Treatments

When seeking drywood termite control options for small areas, heat treatments may be the answer for you. If your termite infestation has occurred in a small, contained area, such as an attic or bedroom, a heat treatment, administered by a high-output propane heater, this treatment may serve as a more efficient option.

This is a welcomed alternative to tenting for homeowners who are facing a smaller-scale infestation. The disadvantage to this type of treatment is the mandatory removal of any and all heat-sensitive items from the affected area prior to treatment.

Cold Treatments

For homeowners researching options for drywood termite control of small areas such as wall voids, excessive cold may used. With the use of liquid nitrogen, temperatures in the affected areas can drop to a lethal level to the termites, eradicating them without harsher techniques. Some homeowners may resist this option as it requires drilling holes into the wall for the injection of the liquid nitrogen.

Wood Injection

Wood injection, often referred to as drill-and-treat applications, have been used for over 80 years for infestations which are in easily accessible areas, and in cases which are also easily detectable. Small holes are drilled into the infested area, and insecticide is injected through these holes.

This form of Drywood Termite Control is a beneficial choice for small infestations, and is often a choice because of the direct application of insecticide. The disadvantage to this type of treatment is perhaps obvious: the need to drill the wood at the site of the infestation. On occasion, a borate surface spray may be applied with the wood injection treatment.

Borate Surface spray or foam is only effective on unfinished wood, so this type of treatment is rarely sufficient on its own. If the infested area is isolated to an easily removed piece of wood, it may be recommended to simply replace it, thus eradicating the infestation before it has a chance to require more difficult treatment.

Choosing your form of drywood termite control will depend largely on your particular infestation and its severity. Research your options and make an educated decision the first time around to eliminate the need for future treatments.
