Do you know what's in your walls? |
Liquid Chemical Barriers work by killing or repelling subterranean termites before they enter the structure. The termites are killed before they enter the structure and/or killed upon leaving the structure to return to the colony. In some cases, when using a repellent chemical such as Masterline Permethrin Plus C, the termites will stay away from the chemical because they have a sense for it and it repels them away from the treated area.
If termites are in the structure and a repellent chemical is used, the termites will go up inside the walls and either remain there and attempt to organize a secondary colony or they will attempt to find a new way out of the structure. This is very seldom successful for the blind subterranean termite workers and is usually the case, in the absence of moisture, they are simply trapped inside the wall, cannot organize a new colony and eventually dehydrate (dry up) and die. It is common in homes that have had chemical treatments performed to find thousands of dead dehydrated termites in walls where the termites were trapped and could not get out.
