How do they work?
Termite chemical barriers or treated zones (using liquid termiticides – termite chemicals) provide a replenishable force field around your property. Treated zones stop subterranean termites gaining concealed access into your property. There are basically 2 major groups of termiticides to choose from in the market today. It is really important that you select the best termite chemical for you needs.
Why is a termite chemical barrier system important?
Proactive precaution is the best form of defense against the attack of subterranean termites. It’s a lot more expensive to repair damage later than to properly protect yourself in the first place.
How is it done?
This option involves treating soil around the entire structure to provide a zone that will kill any termites that enter the treated soil. Depending on the termite chemical (termiticide) used; the chemical soil barrier (treated zone) can also affect / eliminate the entire termite colony.
Treating open soil and garden areas involves a process called Trench, Treat, Backfill, (digging up the soil down to the footings and around piers/stumps, treating the soil and backfilling).
Treating soil under pavers will require the pavers to be lifted.
Treating soil under concrete and tiles can be performed using 2 different methods:
Drill & Inject
Cutting and Re-capping
Drill and Inject
This method involves drilling holes every 150mm-200mm apart through the concrete/tiles and injecting a quantity of termiticide in each hole. The holes are resealed. This method is not as effective as cutting and re-capping since the soil being treated in unseen.
Cutting and Re-Capping:
This method involves cutting the concrete along the perimeter of the structure and then treating the soil using the Trench, Treat, Backfill method. The concrete can be re-capped using new concrete or pavers (to make it easier for future treatments).
If the soil is not of a good enough quality to hold the termiticide, soil replacement may be necessary. This option is designed to provide a much higher level of protection against future termite attack.
What else should I know?
Installation of the termite chemical soil barrier system may involve some property alterations (e.g. moving hot water systems and air conditions systems temporarily, drilling, cutting/removal of concrete etc). This will vary according to the unique property situations. Treated Zones need to periodically replenish. We can arrange systems that make this easy to do in the future.
