Centerfire 75 WSP is a non-repellent termiticide that offershigh performance, affordability and excellent value. Centerfire 75WSP cannot be detected by termites, so they tunnel into the treatedzone and become exposed to the active ingredient, imidacloprid.

Centerfire 75 WSP is the best-valued non-repellent termiticideon the market and can be applied at the lowest rate currentlyavailable on the market today. Centerfire 75 WSP is a post-patentequivalent to Premise 75 WP

Centerfire 75 WSP will provide a professional-grade, long-lasting and effective termite control. Centerfire 75 WSP can be used to do an in-ground perimeter treatment around a home's foundation to prevent termite infestation or for treating localized areas of known subterranean termite activity. It is also excellent for controlling drywood and dampwood termites, borers and other wood-infesting insects in and around basements, attics, crawl spaces, voids, and damaged wood piles.

Centerfire 75 WSP works differently from other termiticide products that are designed to simply repel or keep termites away from the treated soil area without killing them. Centerfire 75 WSP creates an undetectable “Treated Zone®” around the home, where termites unknowingly eat treated cellulose or tunnel into treated soil. The exposed termites then remain unaffected for a few days, before sudden death occurs. In the meantime, the exposed termites are able to spread the Centerfire 75 WSP chemical to unexposed termites by physical contact when they feed or groom the other termites, resulting in a domino death effect which wipes out more of the colony.


- Before beginning a treatment, determine the location of underground utility lines, the main water line shut-off valve, and if there is radiant heat or sub-slab air ducts.

- In heavy clay soils, rod holes should be spaced 3-4 inches apart. In lighter and sandy soils, rod holes can be spaced 6-8 inches apart.

- Where the soil is heavy, Centerfire 75 WSP can be applied by reducing hole spacing, or by increasing the concentrations of Centerfire 75 WSP two-fold in half the volume.

- Houses that have large settlement voids or sand fill should be treated by long rodding underneath the slab.

- Technicians should determine if air ducts in slabs are a perimeter system or a radial system before drilling and treating. Perimeter systems that run along the foundation can complicate treatment.

- Foaming void areas is an effective way to obtain complete coverage.

- Do not treat soil beneath structures that contain cisterns or wells. Consult state and local specifications for recommended distances of wells from the treated area.
