  1. Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences University of Missouri Kansas IPM Education October 2005

  2. Termite Control Tactics • Possible Strategies • Physical • Cultural • Biological • Chemical • Wood Treatments • Soil Barriers • Baits Kansas IPM Education October 2005

  3. Cultural Controls • Avoid wood-to-soil contact • Log piles against structures • Construction debris • Backfill/front stoop shouldn’t contain wood • Moisture management • Drainage away from foundation • Gutters, downspouts well-maintained Kansas IPM Education October 2005

  4. Physical Control • Barriers to tunneling • Sand, basalt, granite, glass, etc. • Grain size of 2.0-2.8 mm. • 20cm thick. • Stainless Steel Mesh • Termi-Mesh • Thick rubber mats • Pre-construction only Kansas IPM Education October 2005

  5. Biological Controls • Nematodes (Steinernema) • Not effective against subterranean termites in field trials • Fungi (Metarhizium) • More successful than nematodes • Bio-Blast (Paragon Professional) • applied as a dust/WP • Bacteria (Bacillus) • Has been studied, but not currently used Kansas IPM Education October 2005

  6. Chemical Controls • Wood Treatments • Reduce feeding on structural wood • Pressure treatments or spray-on • Products • BoraCare/Jecta (Nisus) www.nisuscorp.com • disodium octaborate tetrahydrate • Tim-bor (U.S. Borax) www.borax.com • disodium octaborate tetrahydrate Kansas IPM Education October 2005

  7. Chemical Controls • Chemical Barriers • Applied to soil around structures • 4gal./10ft./1ft.depth • Restricted-use chemicals only • Repellent vs. Non-repellent? Kansas IPM Education October 2005

  8. Why Soil Barriers? • To protect areas of the structure where termites are likely to enter. Kansas IPM Education October 2005

  17. Subterranean Termite Control • Repellent vs. Non-repellents? • Repellent (Pyrethroids) • Termites detect and move away from treated soil • No mortality • Non-repellent (Various) • Termites don’t detect treated soil and enter • Mortality results Kansas IPM Education October 2005

  28. Termidor PerimeterPLUS label • Exterior perimeter • MUST Trench/rod along foundation wall • MUST Drill/rod adjoining slabs/patios • PLUS • MUST treat active sites indoors (+2ft in at least two directions). • MAY treat susceptible areas • Original label directions for spot/partial/full treatments still valid Kansas IPM Education October 2005

  30. Chemical Controls • Managing Reticulitermes Using Baits • Just ‘killing the queen’ doesn’t work • Centers of activity change in habitat • Splitting colonies can occur using soil termiticides • Termite baits seek to address colony networks Kansas IPM Education October 2005

  31. Kansas IPM Education October 2005

  32. Why Baiting? • To reduce the number of subterranean termites in the vicinity of a structure. Kansas IPM Education October 2005

  33. Baiting Methods Four basic methods have been examined: • Monitoring stations followed by consumable bait when termites are located • Consumable bait in stations prior to detection • Consumable bait at the site of infestation • Trapping followed by groomable coating applications and release back into station Kansas IPM Education October 2005

  34. Typical Baiting Sequence In: Termites: Biology and Pest Management MJ Pearce. 1997. Kansas IPM Education October 2005

  35. Baiting Strategies • Areas where foraging is likely • Temperature and moisture consistent • Food sources nearby • Active sites are best • Do not want to disrupt foraging/feeding • Distance between stations • Clustered stations Kansas IPM Education October 2005

  36. Baiting Systems • Design considerations • Disturbance at station • Monitor integrity/acceptance • Type of active ingredient • Palatability of active ingredient • Metabolism of active ingredient • Bait matrix Kansas IPM Education October 2005

  37. Commercial Baits • Sentricon (noviflumeron) • Firstline (sulfluramid) • Exterra (diflubenzuron) • Subterfuge (hydramethylnon) • Advance (diflubenzuron) • Terminate (sulfluramid) Kansas IPM Education October 2005
