How to Eliminate Termites in Chile

The house we are buying was treated by subterranean termites four years ago, according to the vendor. How can we be sure that the treatment was effective? Does the treatment always kill all the termites? After buying the house, should we have treatment again?

The specialists in pest control have a saying: there are two types of housing: those that have termites and those that will have them.

An effective and early treatment can prevent significant damage. Dealing with subterranean termites is complicated, since those that cause damage are experts in remaining hidden while devouring critical parts of our homes.

The area in the white rectangle is a shelter tube, the most common sign of termite infestation. Termites make these earth-colored pipes as protected tracks from the ground to the wood they feed.

Wood that has been infested may look rotten.

A pre-purchase inspection must be carried out, destroyers of the insect wood. The report and the diagram of the previous treatment should be compared with the current conditions. New signs of damage, or other evidence of reinfestation, certainly conditions additional treatment. Licensed exterminators will not apply chemicals unless there is an active infestation.

Until recently, it was the only method of treatment to inject a chemical into the soil and sometimes into the Foundation. This creates a layer that termites have to pass as they enter or leave the structure. Chlordane was a common termiticide used before 1988 and is considered by industry experts to provide protection for 30 to 40 years. Most recent products have a shorter estimated time of protection, some as little as 5 years.

The most recent treatment is called a prime system. It consists of holes drilled in plastic spikes that are inserted into the ground around the house. Bait (cellulose) is placed inside the ears and then they are monitored. Once there is a hit the inert bait is connected with the termiticide. Many exterminators are skeptical that this new method is completely effective. Some use the system for monitoring only or in conjunction with the injected substance.

After a careful evaluation of the pre-purchase of the house, a pest management plan must be established that involves both the owner and a licensed experience exterminator. Service contracts that include annual inspections are generally available. Some offer a guarantee for the cost of treating future infestations.

Moisture, vegetation and soil around this wooden window frame are inviting for termites to come in for dinner. This owner could subtract the possibilities of infestation by following some of the steps indicated below.

Here are some things that any owner can do to eliminate the common conditions that invite termites inside a buffet:

  • Remove any vegetation, mulch or soil that completely covers the Foundation or comes in contact with any wood surface (siding, basement window frames, etc.).
  • Replace wood that has contact with the ground (roof supports, trellis, steps, fencing walls) with treated materials.
  • Keep stored wood or other wood well away from the structure.
  • Termites need moisture to survive. For this reason they need to have access to the land, unless there is a perpetual source of moisture inside the home. Ensure tracks away from the base of the classification. Further:
    • Maintain the channels regularly and extend the water drops.
    • Take measures to reduce humidity in basements.
    • Immediately repair any roof leaks, flashings, plumbing or plumbing.
