When it comes to termites, exterminating these pests from your house is only part of the solution. It’s vitally important to eradicate the colony and if you do not, your house may come under attack from termites all over again. There are a number of strategies for dealing with the termite colonies, such as termite baits, chemical barriers and dusts.
Baits are set up near areas of activity to attract termites. The termites ingest the bait product and then return to the nest, and the poison is then spread throughout the colony due to social and feeding habits. This method may be effective but it tends to be slow and is not the best option where there needs to be immediate control. According to the CSIRO, the active elements of baits may include trioxide, hexaflumuron, noviflumuron or chlorfluazuron.
These are usually set up around the building foundations or under the house, and may be the in-soil kind — where the termiticide is placed in the soil; or in-plastic i.e. a plastic sheet containing the chemical. The chemical is undetectable to termites and is carried back to the colony, where it is spread to other termites, consequently having a devastating effect on the colony. The active elements of the termite control chemicals may include bifenthrin, chlropyrifos, deltamethrin, fipronil or imidacloprid.
Termite control dusts work a bit like chemical barriers, in that the product is applied to the termite infested area, and then carried back to the colony. Dusts usually contain arsenic trioxide, fipronil or triflumuron as their active ingredient.
Direct Colony Elimination
If the termite controlling specialized can locate a nest — in a tree or a tree-stump for example — it is possible to destroy the colony directly, either by removing the tree or stump, or by applying a termiticide or arsenic trioxide to the area by a small hole.
Whichever method of termite control is used, it is basic to apply enough of the chemical product to eradicate the whole colony. If a dusting method is used for example, and there is insufficient termite control product transferred back to the nest, the colony may continue to thrive.
Termite control should be always be handled by a pest extermination specialized, who not only has the licence to use termiticides and other termite control chemicals, but who’s qualified and experienced enough to know which method should work the most efficiently on your particular character.
