Xterm is the trusted non-invasive and environmentally friendly defence against termite infestations. With our Above Ground System (Xterm Bait Station) and In Ground System (Xterm IG Bait System) termites are baited and their colonies eliminated, without drilling into a building’s structure, while Wazary 10FL, our repellent termiticide is effective and odourless, and approved by Singapore’s National Environmental Agency (NEA) in water catchment areas.

Wazary® 10FL is a repellent termiticide, and it’s one of the most active ones yet invented. Many years of use in countries throughout the world, have shown that Wazary® 10FL forms one of the most active termiticide barriers on the market. To obtain at least 5 year protection, global field trials have indicated that dilutions of 1 : 40 (0.25% as a.i.) are recommended. Lower dilutions of 1 : 80 (0.125% as a.i.) have been shown to work for up to 3 years.

Wazary® 10FL is a water-based flowable (suspension) concentrate, which greatly reduces the hazards associated with the more common oil-based formulations. The formulation has the added advantage of being virtually odourless even in its concentrated form, ensuring no customer complaints of malodour following application.

The main active isomer content of Wazary® 10FL has been determined to have a Koc value of 630,597 and is classified as “very strongly” adsorbed from water into organic material in the soil. This indicates that the active binds to soil better than other commercially available termiticide treatments, in effect making the soil an anti-termite barrier, and greatly extending the residual life of the product.

Using USA Environmental Protection Agency assessments on soil leaching, 90% of applied Wazary® 10FL was found to tightly bind in the top 3cm of soil. Less than 2% ever enters the leaching water, and most of this reabsorbs again. The soil adsorption was found to be irreversible.

Wazary® 10FL is approved by Singapore’s National Environmental Agency (NEA) for use in water catchment areas.

Wazary® 10FL applications at dilutions as high as 1 : 2000 (Note: normal dilution is between 1 : 40 and 1 : 80) have been shown to provide at least 75% protection from termite penetration, explaining the product’s excellent long term residual action.

Much has been said about the relative benefits of repellent and non-repellent termiticides. With most new product arrivals being non-repellent, the argument has recently been biased towards non-repellents. It should be remembered that thorough applications of the best available repellent and non-repellent products will provide similar excellent levels of protection. In fact with its extremely high Koc value (soil binding capacity), Wazary® 10FL often gives the longest residual effect, whilst many non-repellent products suffer from activity loss after a few years due to leaching from the point of application.

Professor B. T. Forschler, looked at soil termiticide efficacy and discovered results with seven different formulated termiticides which indicated that the moniker repellent or non-repellent are a function of concentration, not the purview of any particular class of chemistries.*

In other words, any termiticide is repellent at “high” concentrations and all termiticides are non-repellent at “low” concentrations …”**

In addition, similar studies conducted by Professor C.Y. Lee, found that repellent or non-repellent characteristics of termiticides were dependent on the concentrations of termiticides used.***

Test Method (Repellency Test)

A wet filter paper was placed in a Petri dish. One half of the surface of filter paper was covered with 5g of soil treated with Wazary® 10FL and the other half was covered with 5g of untreated soil. Treated and untreated soils were separated by 5mm as figure shown below.

Twenty Formosan subterranean termites were released in the centre part, between the treated and untreated soil. The results are shown in the table below.

Repellency (%) of Wazary® 10FL

Field test of Wazary® 10FL on subterranean termites conducted by the Royal Forest Department, Thailand showed that if applied at 1:40, Wazary® 10FL gives 6 years protection.

Average damage for the Control replicates over this same period was 85.4%.

*Data was non-reflective of actual protection efficacy as one of the replicates was damaged.

For long-term protection, Wazary® 10FL should be diluted at the rate of 1 part : 40 parts water and applied according to label recommendations. For shorter term control, dilutions of 1 part : 80 parts water may be considered.

Treatment Applications

Wazary® 10FL should be shaken before use.

Pre-construction Treatment

For floor slabs porch floors and entrance platforms, apply diluted Wazary® 10FL at the rate of 4 litres per square metre or 7 litres per square metre if fill is washed gravel or other coarse material. On hollow block foundations, or voids in masonry, apply solution at the rate of 7 litres per three linear meters. In crawl spaces, apply the solution at the rate of 5 litres per linear meter per 30cm of depth from grade to bottom of foundation. Apply the solution on both sides of the foundation with special attention around pipes and piers.

Post-construction Treatment

Apply the solution at the rate of 5 litres per linear metre to trenches dug to the base of the foundation of the building being treated, or via drill holes spaced at 30cm intervals in flooring slabs. Excavated soil should be treated and used as a backfill as well as the soil under and around porches. To avoid exposure of treated soil to direct sunlight, exposed areas may be covered with a thin layer of untreated soil.

Remedial & Spot Treatments

If there is evidence of termite re-infestation after the initial treatment resulting from disruption of the chemical barrier that can arise due to human activity such as excavation, construction and landscaping, or simply following an incomplete initial treatment, retreatment should be made in these areas in accordance with the application techniques described within the Post-construction section.
