Termidor. DRY • Cellulose-based formulation (0. 5% ai) that termites can consume • Small amounts (grams) applied directly into galleries and active sites • Option of treating many off-structure sites • Controls subterranean and drywood termites • Easy and efficient bulb dispenser

Termidor. DRY Caveats Application options are liberal 1 puff = 0. 03 g 0. 1 -1 g in galleries 0. 2 -2 g in voids 0. 3 -3 g in carton nests • Not a stand-alone termite treatment – Use as part of a “defined” treatment in GA • Not a void treatment – Designed to be applied to active galleries

Termidor® HE Less Labor Intensive than “Conventional” Soil Treatments • 0. 125% (versus 0. 06% now); same amount of chemical used--i. e. , 2 -fold concentration but half as much used!) • 2 gal per 10 feet (versus 4 gals per 10 now); use of 50% less water • 2”x 4” trench (versus larger trench now); almost 80% less soil removed from trench • 2 foot maximum treatment depth (versus 4 feet now) • 18” drill & rod spacing (versus 12 inch now); 30% less drilling of holes in concrete • Termidor HE is not yet registered in GA

(1) Treat soil at 4 gals/10 feet (drill [12 inches] attached slabs) per foot of depth up to 4 feet. AND (2) Treat voids at 2 gals/10 feet; drill (12 inches) into voids. Liquid Termiticide Use “Conventional” Soil Treatment

Subterranean Termite Shelter Tubes • Protect termites from predators • Maintain high humidity inside the tube

Some things Homeowners Should Do and Not Do to Avoid Termite Infestations Yes! No! No! Yes! No!

Products Used to Control Termites A New Era in Termite Control • Before 1995 termite control was defensive. The wood inside a structure was protected with repellent, liquid termiticides. ü Termite populations in the vicinity of the structure are not lessened with repellent products; termite threat remains. • Beginning in 1995, termite control became offensive. The wood inside a structure is protected with baits and nonrepellent, liquid termiticides. ü Termite populations in the vicinity of a structure are lessened with baits and non-repellents; termite threat is reduced.

Liquid Termiticide Use ”Conventional” Soil Treatment • Dig a trench in the soil around (a) outside foundation walls, (b) inside wall in crawlspace, and (c) piers/pillars in the crawlspace. • Fill the trench with termiticide at a rate of 4 gals per 10 linear feet per foot of depth to the top of the footer (maximum treatment depth is 4 feet). • NOTE: This rate of application is equivalent to 0. 4 gals per linear foot (or 0. 8, or 1. 2, or 1. 6 depending on footer depth).

Dig a trench in the soil, and fill with termiticide at a rate of 4 gals per 10 linear feet per foot of depth to the top of the footer (or 4 ft. max). (A) Outside Liquid Termiticide Use “Conventional” Soil Treatment (B) Crawlspace Side of Wall

Crawlspaces Treatment of Piers Trench around piers

Liquid Termiticide Use Treating the Soil That’s Under Concrete Slabs • Wherever a trench cannot be dug along a foundation wall, because concrete is in the way, the concrete must be drilled every 12 inches and the termiticide then injected through each hole into the sub-slab soil. • The rate is the same as if concrete were not present (4 gals per 10 linear feet per foot of depth to the top of footer or 4 feet). • NOTE: If the holes are 12 inches apart (per State Regulation), each hole receives 0. 40 gals.

Liquid Termiticide Use Treating the Soil That’s Under Concrete Slabs Special Treatment Option: Foaming in Voids

Liquid Termiticide Use ”Conventional” Treatment of Masonry Voids • Drill holes in concrete block/brick wall and pier voids so that termiticide can be injected into the masonry void. • Rate of application is 2 gals per 10 linear feet of wall. • NOTE: If the holes are 12 inches apart (per State Regulation), each hole receives 0. 2 gals.

Drill holes in brick/block every 12 inches and inject termiticide at a rate of 2 gals per 10 linear feet (or 0. 2 gals per hole). Drill through brick Drill through block Liquid Termiticide Use “Conventional” Void Treatment (A) Outside (B) Crawlspace Side of Wall
