Pesticides expert witness Allan Snyder; ACGIH, AIHA, SPCI, of AFC Forensic Consulting writes on the treatment and control of termites:
Treatment and control techniques vary depending on the species causing an infestation.
• Multiple colonies of the same species of termite or more than one species of termite can infest a building.
• Subterranean, and less frequently, dampwood termites can have nests at or near ground level, so control methods for these can be similar.
• Drywood termites nest above ground and require different treatment methods than dampwood and subterranean termites.
Control methods include:
• Excluding termites from the building by physical and chemical means • Using mechanical and chemical methods to destroy existing colonies.
