Subterranean Termites

Trenching, rodding and treating the soil beneath the house or around the house.

Treatment for Subterranean Termites

  • Create a chemical barrier to prevent termites from accessing your home through the soil. This can be done by either trenching, rodding or drilling and treating.
  • Treating the infested areas will eliminate the termite colonies. Treating the entire perimeter of the home will protect the entire structure.
  • Drilling is only necessary if there is concrete over the infested soil. Once a hole is made, the chemical is then injected into the soil and then sealed.

Drilling & Treating infested areas for elimination and all the perimeter of the house for protection.

Tips to prevent Subterranean Infestation

  • Subterranean termites require moist environments.
  • To prevent termites from finding a food source, there should be no contact of building woodwork with the soil or fill. Exterior woodwork should be a minimum of 6 inches above the ground, and beams in crawl spaces at least 18 inches above the ground, to provide ample space for future inspections.
  • Ventilation openings in foundations should be designed to prevent dead air pockets
  • Landscape plants and irrigation should not be placed within 2 feet of the foundation.
  • Annual inspections should consist of searching for mud tubes, winged adults, shed wings, or wood damage to discover evidence of an active termite infestation.
  • Any wood that contacts the soil, such as fence posts, poles, and general foundation structures, should be commercially pressure treated, and should not be attached to the house.
  • Eliminate leaks and moisture from the home in general.

Subterranean Termites

Subterranean termites are the most destructive of the three species and infest wood from underground. This species of termites can not be eliminated with fumigation, spot treatment or heat treatment because their colonies are built in the ground.

The only way to eliminate Subterranean Termites is by applying insecticides to the soil around and under the building.

Subterranean Tubes

Subterranean termites live within the wood and underground, which makes them often difficult to detect. A good way to determine if there is a subterranean termite infestation is to look for winged reproductive (or swarmers), shed wings, mud tubes, and wood damage.

To protect themselves from drying out and predators, subterranean termites build mud tubes. Houses should be inspected at least once a year for evidence of tubes. Cracks in concrete foundations and open voids in concrete block foundations are also hidden avenues for termite entry into structures. Aside from wood damage, subterranean termites can damage building insulation.

The best way to eliminate and control subterranean termite infestation is with a combination of methods. It starts with a professional inspection following with chemical application and habitat modification such as eliminating any moisture condition, removing infested or damaged wood and eliminating any cellulose-based products from the ground area.

Pest management professionals are provided special training because of the hazards involved in applying insecticides to the soil around and under buildings. Applications in the wrong place can cause insecticide contamination of heating ducts and/or damage to radiant heat pipes or plumbing used for water or sewage under the treated building. Soil type, weather, and application techniques influence the mobility of insecticides in the soil; soil-applied insecticides must not leach through the soil profile to contaminate groundwater or run off to contaminate surface water.
