termiticides

Termiticides are pesticides formulated to kill or deter termites and to create a protective barrier around structures or in termite-infested areas. They are used to prevent termite entry, reduce infestation risk, and limit structural damage caused by subterranean, drywood, and dampwood termites. Termite control programs typically involve site assessment, selection of a termiticide strategy, and subsequent monitoring.

Liquid soil-applied termiticides are applied around the foundation or beneath slabs to form a chemical barrier or zones where termites forage. Non-repellent formulations allow termites to move through treated soil and transfer the toxicant within the colony, while repellent products create a deterrent effect. Bait systems place stations with slow-acting toxicants or growth inhibitors at intervals; foraging termites carry material back to the colony, potentially eliminating it over time.

Effectiveness depends on correct product choice, thorough application, termite species, and site conditions. Barrier treatments can last several years in favorable soils, but may require reapplication after damage or structural changes. Baiting programs typically take months to years to achieve colony decline and may not immediately stop existing infestations. Regular inspection is essential for long-term control.

Safety and regulatory considerations vary by country. In many regions termiticides are restricted-use pesticides requiring licensed applicators. Labels specify application methods, timing, and protective equipment. Environmental concerns include impacts on non-target organisms and aquatic ecosystems, and care must be taken to prevent runoff and soil contamination. Alternatives to chemical termiticides include physical barriers and moisture management.
