Termite Information

Termites

Subterranean termites are the most damaging insects of wood. Their presence is hard to notice and damage usually is found before the termites are seen. Prevent infestations because if they occur they will almost always need professional pest control service.

 

Signs of Infestation

Generally, the first sign of infestation is the presence of swarming termites on the window or near indoor light. If they are found inside the house, it almost always means that they have infested. Other signs that may be found are termite wings on windowsills or in cobwebs, and shelter tubes, which are tunnels constructed by the termites from soil or wood and debris. Usually, wood damage is not found at first, but when it is found it definitely reveals a termite infestation. Anywhere wood touches soil is a possible entry into a home for termites. Examine wood, which sounds dull or hollow when struck by a screwdriver or hammer. Inspect suspected areas with a sharp, pointed tool such as an ice pick to find termite galleries or their damage.

 

Control

Control measures include reducing the potential infestation, preventing termite entry and applying chemicals for remedial treatment.

 

Inspection

Inspect thoroughly to determine if there is an infestation, damage, and/or conditions that could invite a termite attack or the need for remedial control measures. The tools and equipment needed for an inspection include a flashlight, ice pick or sharp-pointed screwdriver, ladder and protective clothing.

 

Prevention

Many termite problems can be prevented. The most important thing to do is deny termites access to food (wood), moisture and shelter. Follow the suggestions below.

  • have at least a 2-inch clearance between the house and planter boxes or soil-filled porches
  • eliminate all wood-to-soil contacts such as trellises, fence posts, stair casings and door facings (they can be put on masonry blocks or on treated wood)
  • separate shrubbery from the house to help make it easier to inspect the foundation line
  • use pressure-treated wood so that rain will not rot it
  • seal openings through the foundation
  • remove wood scraps or stumps from around foundations
  • have at least 12″-18″ clearance between floor beams and the soil underneath

 

Chemical Treatment

Termite treatment often requires specialized equipment. Therefore, it is recommended that you always use the services of a pest control operator because he is familiar with construction principles and practices, has the necessary equipment and knows about subterranean termites.

 

Exterminating Termites

If you think you have a termite infestation in your house, you need to call a structural pest control company to conduct a professional inspection. To find a company, ask friends or coworkers for recommendations, or check the yellow pages. If the inspection finds evidence of dry wood termites, you have several options, depending on the degree of infestation. Fumigation and heating of the entire house are the only options that ensure eradication in the entire structure. If the infestation is contained in a small area, local or spot control may be effective. However, hidden infestations in other part of the structure will not be eradicated.

 

Total (Whole-House) Eradication

For the heat method, pets, plants, and other items that might be damaged by high temperatures must be removed. The house is then covered with tarps, and hot air is blown into the tarp until the inside temperature reaches 140° to 150°F and the temperature of the structural timbers reaches 120°F. The time to complete this procedure varies greatly from one structure to another, depending on factors such as the building’s construction and the weather conditions. The procedure may not be practical for structures that cannot be heated evenly.

 

Local or Spot Control

Local or spot control methods include the use of pesticides, electric current, extreme cold, localized heat, microwave energy, or any combination of these methods. Local or spot control also includes the removal and replacement of infested structural timber. These methods are intended to remove or kill termites only within the specific targeted area, leaving open the possibility of other undetected infestations within the structure. These treatments are NOT designed for whole-house eradication. Any pest control company that claims whole-house results with local or spot control methods is guilty of false advertising and should be reported. Local or spot treatment with pesticides involves drilling and injecting pesticides into infested timbers, as well as the topical application of toxic chemicals. The electric current method involves delivering electric energy to targeted infestations. For the extreme cold method, liquid nitrogen is pumped into wall voids adjacent to suspected infestation sites, reducing the area to -20°F. The localized heat method involves heating infested structural timbers to 120°F. The microwave method kills termites by directing microwaves into termite-infested wood.

 

 

If you see the following signs in your house, you might have termites:

  • 

sawdust-like droppings
  • dirt or mud-like tubes or trails on the structure
  • damaged wood members (like window sills)
  • swarming winged insects within the structure, especially in the spring or fall
