Termite Treatment - Soil/Liquid

Why is a small untreated gap in the treated zone more likely to cause failure with a repellent termiticide than with a non-repellent one?

• Termites detect and are repelled by the treated soil, so they probe until they locate the untreated gap and pass through unharmed ✓
• Repellent termiticides break down faster, so the gap is the only place left with active residue
• Repellents kill on contact at the gap edge, so the gap is irrelevant to performance
• The gap forces termites to ingest more repellent than they otherwise would

A conventional soil/liquid termiticide application around a structure is designed to achieve what primary outcome?

• A pheromone that lures foraging termites away from the structure
• A continuous treated zone in the soil that subterranean termites cannot cross without contacting treated soil ✓
• A fumigant gas that penetrates the wall voids of the entire structure
• A growth-regulating bait matrix distributed at stations around the lot

How does a non-repellent termiticide such as fipronil or imidacloprid control subterranean termites differently from an older repellent pyrethroid?

• Termites detect and avoid the non-repellent zone, so they are walled out before contacting it
• The non-repellent vaporizes into wood voids, while the pyrethroid stays in the soil
• Termites cannot detect the non-repellent treated soil, so they tunnel into it and pick up a lethal dose ✓
• The non-repellent only works in pre-construction applications, never post-construction

For a POST-construction subterranean termite treatment of an existing slab home, which set of application methods is used to establish the treated zone around and beneath the foundation?

• Broadcasting granules across the lawn and watering them in
• Spraying the wood framing inside the wall voids only
• Fogging the crawlspace air with an aerosol insecticide
• Trenching and rodding the soil along the foundation and drilling through the slab to inject beneath it ✓

When mixing and applying a soil termiticide, what governs the dilution and application rate the applicator must use?

• The applicator may use a stronger-than-labeled mix on heavy infestations to ensure a kill
• The rate specified on the product label, which is legally enforceable and must be followed ✓
• Whatever rate the customer requests in the service agreement
• A reduced rate is always acceptable to lower cost as long as the soil is visibly wet
