Subterranean termites are attracted to the moisture in and around structures. The most recommended action item is to correct moisture issues by adding a sump pump and vapor barrier under a structure. We are skilled in detecting subterranean infestations because termites create shelter tubes out of mud, which allows them to travel safely from the soil to the wood. When we get calls from people who suspect they have termites, they generally see the flying termites first. These are actually called “swarmers “ or reproductive. They are black in color and have equilateral wings. The other commonly seen termite is the worker that is smaller and a transparent white color.
What are the control methods for subterranean termites? In most cases a full perimeter treatment is needed. This means that the perimeter of the structure is treated every foot and in the active area and this can be done by soil injection or trenching. In some cases a localized treatment can be sufficient; this means that only the area where activity is noted will be treated.
