Insecticides Barriers in Termites Extermination
Only certain insecticides are used for termites extermination purposes.They can be applied before construction of a building, on the foundation soil. They can also be applied after construction by drilling holes in the concrete floor.In both types of chemical application, the purpose is to create an insecticidal barrier that prevents termites from entering the building.
Treating before construction is easier and gives better protection. In the trade these are commonly referred to as pre-treatments or “pre-treats.” Insecticides are applied to the soil as a means of blocking concealed access to a structure by subterranean termites .
Treating after construction is usually done to protect a building against further damage by termites after they have been discovered in an existing building. Holes are drilled in the ground floor along the perimeter of the building, and insecticides are pumped into the ground beneath the floor. Any piers, foundation walls, patios, trees, retaining walls, fences or landscaping timbers that come in contact with your property may require treatment.
The chemical can work in a number of ways, depending on which chemical is used. The longevity of chemical treatments is anywhere between seven (7) and ten (10) years.
Spraying insecticides indoors is not a good way in termites extermination, and it can endanger the health of the occupants. Outdoor poles can be treated by spraying them before burying them or by drenching the soil in which they are buried.
Trees are treated by removing the soil from the base of the tree and allowing the insecticide to seep into the soil. Larger trees require a larger volume of insecticide. Spraying only the tree trunk and surface soil is not a good way of protecting them against termites.
Make sure that all termiticides used by termite exterminator are registered and approved by the pesticides control authority in your country.
