Preventive Controls Clause Samples

Preventive Controls. Inject soil with a registered termiticide (chlorpyrifos and other chemicals can be used) prior to laying the foundation • Eliminate direct contact between soil and wood. • Store wood piles as far from structure as practical. • Remove all cellulose debris from under structure. • Use termite baiting with monthly monitoring. Prevention for Drywood and Subterranean Termites • Monitor structure periodically to detect termite presence or conditions that can lead to infestation. • Reduce moisture level of wood in structure by: • fixing leaks, gutters, drains, downspouts, etc. • improving drainage around structure • improving ventilation • changing irrigation and landscape practices that cause water damage to structure or increase water collection near structure • Eliminate direct contact between soil and wood. • Replace damaged wood with borate treated wood. • Replace wood with aluminum, concrete, or vinyl in areas most vulnerable to moisture. • Remove stumps and other wood debris from under and around the structure. • Store wood piles as far from structure as practical. • Plant trees and shrubs away from buildings to insure proper air circulation and reduce moisture retention in building. • Screen vents. • Maintain buildings in good repair. Physical controls • Fumigate with heat. This is usually as a spot treatment because whole house treatments are expensive. • Microwaves • Liquid Nitrogen • Treat wall voids with desiccating dusts such as silica gel. Least hazardous chemical controls • Borate-based wood treatments Physical controls • Use pre-construction barriers such as stainless steel mesh and sand. • Treat wall voids with desiccating dust such as silica aerogel. Reduced-risk chemical controls • Borate based wood treatments • Termite baits with the following active ingredients: (Note: to be effective, termite bait stations must be closely monitored) • Diflubenzuron • Hexaflumuron • Sulfluramid
