1 Subterranean Termite Control Update Daniel R. Suiter Department of Entomology UGA Griffin Campus Griffin, GA ;

2 Current Issues in the Termite and Pest Control Industry 1.Fipronil (Termidor) patent issues. 2.BASF has two new termite control products: a.Termidor Dry b.Termidor HE 3.Dow AgroSciences has upgraded Sentricon, their termite bait. 4.DuPont registered a new termiticide, called Altriset, in On-going issue with termite inspections and the Georgia Association of Realtors. 6.Non-Termite Issue: Pyrethroid insecticide use restrictions around homes.

3 Current Issues in the Termite and Pest Control Industry 1.Fipronil (Termidor) patent issues. 2.BASF has two new termite control products: a.Termidor Dry b.Termidor HE 3.Dow AgroSciences has upgraded Sentricon, their termite bait. 4.DuPont registered a new termiticide, called Altriset, in On-going issue with termite inspections and the Georgia Association of Realtors. 6.Non-Termite Issue: Pyrethroid insecticide use restrictions around homes.

4 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 TermidorDRY

5 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 TermidorDRY Application options are liberal 1 puff = 0.03 g g in galleries g in voids g in carton nests Caveats

6 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 Termidor ® HE Less Labor Intensive than “Conventional” Soil Treatments

7 (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

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

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

23 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. 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 non- repellent, liquid termiticides. Termite populations in the vicinity of a structure are lessened with baits and non-repellents; termite threat is reduced.

24 Non-Repellent, Liquid Termiticides Termidor 9.1SC (BASF Corporation) 0.06 fipronil Premise 75WP (Bayer Corporation) 0.05 or 0.10% imidacloprid Phantom (BASF Corporation) chlorfenapyr

28 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).

29 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). (B) Crawlspace Side of Wall (A) Outside Liquid Termiticide Use “Conventional” Soil Treatment

30 Crawlspaces Treatment of Piers Trench around piers

31 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.

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

33 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.

34 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). (B) Crawlspace Side of Wall (A) Outside Liquid Termiticide Use “Conventional” Void Treatment Drill through block Drill through brick

35 Answer: 12 gals; How’d I get that? (0.4 gals/ft outside soil) + (0.4 gals/ft inside soil) + (0.2 gals/fit in void) is the equivalent of 1 gal/ft ( ). So, to this 12 ft. wall you’d apply 12 gals. This wall is 12 feet long. How much chemical is needed to treat it?
