As the detection of the extent of damage caused by dry wood termites is difficult, experts do not recommend the-counter remedies for the treatment against termites, dry wood. These termites live inside wood and show a wide dispersion. Usually, the extent of feeding damage, the number of shed wings and feces, and the number of kick-out holes gives an idea of the severity of the infestation. fecal pellets of dry wood termites are hexagonal, and kick-out holes are usually the size of a BB. Termites use the hole to push their pellets.

control methods against dry wood termites are classified into two types: unstructured and localized or spot treatments. Trafficking treatment throughout the structure of treatment of all structure-infected with both visible and invisible parts and is much more effective. Spot treatment, as its name suggests, deals with a particular area infested, which is more restrictive.
Treatment throughout Structure

If properly applied simultaneously, it is possible to achieve high levels of efficiency with fumigants. In about three hours, termites will be killed. A Pest Control, which requires monitoring of gas lines to be installed inside the structure infection, the success rate was the highest. Fumigation unguarded not have the same success rate as it may not be enough gas concentration to kill infestations.

Problems

* The difficulty of installing tarpaulins
* Determine the appropriate dosage of fumigant
* Emergency food
* The lack of residual control (long-term protection against termite attacks)
* The evacuation of the building for 3-4 days during treatment and, later, in a breakdown
* The availability of roofs damaged by the use of tarpaulins

Heat treatment

In the method of heat, made the structure is heated to a minimum of 120 ° F, and the heat is maintained for at least 33 minutes. With this method, the entire structure can be processed without the use of chemicals. The structure must be evacuated for a few hours, rather than the few days required with other fumigants. huge buildings, such as condominiums and apartments, can be treated in stages, instead of once. The method of heat is used for spot treatment as well.

Problems

* Sometimes a problem may arise to raise the temperature of the inner core of the large structural beams infested
* The damage to heat sensitive components, such as plastics, electric plugs and cables
* No residual control

Spot treatment

There are chemicals and non-chemical treatment available, such as aerosols, liquid and dust insecticides. For liquids and methods of dust to be practical, termites must touch or ingest the insecticide. Spot treatments should be applied only by certified applicators. Some of these treatments showed 13% to 100% effective in eliminating termites. Treatment with liquid nitrogen is an effective method of treatment instead. It causes a sudden drop in temperatures, which kills termites.

Problems

* Liquid nitrogen has no residual activity when used alone.
* Small amounts of damage occur that holes must be drilled for inserts chemicals.

Microwave Devices

microwave devices used for spot treatment to kill termites in the wood itself. They leave no chemical residue.

Problems

* Accuracy of detection is essential to the success of these devices.
* They can damage the surface or inside of the wooden planks.
