What to do when you find Termites
Do not disturb the Termites or their workings!
The first stage of any Termite treatment should be a thorough inspection of the property in accordance with AS3660 or AS4349!
Colony control treatments are nest destruction techniques. They are used to eliminate Termite nests, using indirect methods such as the use of a toxicant bait, or injection of a termiticide “dust” into the galleries where the termites are currently working. Both methods rely on a “transfer effect” to eliminate the nests, but work in different ways.
All methods rely on the social relationships and grooming habits of the termites transferring the active ingredient back to the nest. Colony Control techniques take a matter of time to work, depending on the time of year, and the species of termite, location, and the system and product used. There is generally a noticeable change within a couple of weeks, but in some instances it can take a number of months. During this time it is important that there is no disturbance to the bait, or treated area, to allow maximum transfer back to the nest.
If Termites are found in a building, a perimeter treatment is recommended. Termite chemical barriers are popular since they can provide an ongoing level of protection for your property.
This involves treating soil around the entire structure to provide a zone that will kill any termites that enter the treated soil. Where the perimeter is soil, it will be Trenched, Treated and Backfilled. This involves digging a trench down to the footings of a building (where applicable). The trench is flooded with termiticide as the soil is backfilled into the trench, creating a chemical soil barrier. Where the perimeter is concrete, you Drill and Inject. The Drill and Inject method involves drilling holes through the concrete and injecting termiticide in each hole. The holes are then resealed.
Richards Pest Control uses Non-Repellent Termiticides, such as Premise (Imidacloprid), and Termidor (Fipronil) to protect your investment. The advantage of a non-repellent termiticide, is that it creates a “treated zone” rather than a chemical barrier. As Termites enter this zone, they will come in contact with the termiticide. If they go deep into the zone, they will contact a high enough dose that they will be killed.
If they enter the zone and do not recieve enough of the termiticide, they will return to the other members of the nest, and provide some transfer to termites that haven’t come into contact with the treated zone. This is known as the “Domino Effect”.
Baiting and Monitoring Systems
Hexaflumuron, a chitin synthesis inhibitor, inhibits the termites’ ability to produce chitin (skin substance). As worker termites feed on the bait material, they transfer the Hexaflumuron throughout the entire colony via a process known as ‘trophallaxis’. Termites shed their skin (moult) a number of times throughout their lives as they grow or as their skin is damaged. When they next moult, the exposure to Hexaflumuron renders them unable to produce chitin. Consequently they die, leading to the elimination of the entire colony.
