Controlling Termites With Chemical Termite Treatments
Termites have the potential to wreak havoc to your house, destroying the foundation of the house as well as other parts. If left unchecked, termites can cause damage running into thousands of dollars in repairs. It, therefore, pays to keep these pests at bay. Moreover, when you notice their presence, you need to take immediate and decisive steps to get rid of them.
Pre-Construction Termite Barriers
Smart home builders are now turning to pre-construction termite barriers in increasing numbers. These are an effective termite treatment measure applied in the pre-construction phase of your building project. Think of it as a cost effective insurance against future termite ingress and potential building repairs in the tens of thousands of dollars. If you’ve seen devastated owners who’ve just learnt of extensive termite damage to the homes, you’ll appreciate that dealing with termites at the pre-construction phase is the only way to go.
Pesticides Approved For Use As Termite Barriers
Termite control should only be conducted with authorised chemicals. Only chemicals approved by the Australian Pesticides and Veterinary Medicine Authority should be used. Herein are the registered termiticides that are approved for use by local experts.
Barrier chemical treatment is a pre-construction or perimeter pesticide treatment that aims to keep termites away from a property.
Repellent termiticides – These products are used to deter termites from getting near your house. The pesticide binds with soil to create a barrier between your house’s foundation and the termite. Additionally, these chemicals do not have a chain reaction – they do not affect other termites other than the termites that come into contact with the barrier.
The chemical that falls under this classification is Bifenthrin, which is a synthetic pyrethroid pesticide. It is the active ingredient in Biflex and it is sold in three concentrates such: 0.25% (three years), 0.05 % (ten years maximum) and 0.1% (at least for ten years).
Non-Repellent Termiticides – These termiticides are used to repel as well as kill termite (in high doses). However, unlike the non-repellent variety of pesticide barrier treatment, they have a chain reaction, when a termite comes into contact with them and goes back to their colonies, other termites are also affected. Such termiticides Imidacloprid found in Premise and Fipronil found Termidor.
Another chemical used in termite barrier treatment is the chlorpyrifos.
Pesticides Approved For Spot Treatment
Spot treatment of termites is when one sprays chemicals on termites that active within their surroundings. The approved termiticides for spot treatment are two, and they are sold in powder form. A puffer device is used to apply the treatment with both termiticides. They include Arsenic Trioxide and Triflumuron, which interrupts the life cycle of the termites. However, in many regards, Triflumuron is the better option as it is less toxic to human beings than the Arsenic Trioxide, which is classified as having high to very high toxicity levels in humans.
Other Approved Termite Treatments
The above termiticides are not the only pesticides approved for treating termite in Australia. There other pesticides that are used for other application scenarios. These includes:
Hexaflumuron – According to the Australian Pesticides and Veterinary Medicines Authority, Hexaflumuron is only approved for termites treatment in a bait matrix system. It is never applied directly to the termites but does affect the life cycle of the termites, thus negating the growth of a colony.
Chlorfluazuron – This is an incest growth-inhibitor also used in a bait matrix system. It possesses no threat to human beings, and it is considered among the least toxic.
Permethrin – This pesticide is meant to control termites in trees. It is used to destroy their colonies.
