Sample questions
A customer asks why a borate product such as Bora-Care or Tim-bor (disodium octaborate tetrahydrate) cannot simply be sprayed into the soil around the foundation to replace a conventional soil-applied termiticide. What is the correct explanation of how borate wood-treatment products function?
- They are wood treatments that protect the wood itself and are not formulated or labeled to be applied to soil as a continuous termiticide barrier ✓
- They form a long-lasting repellent chemical barrier in the soil that is more durable than non-repellent liquids
- They volatilize through the soil as a fumigant to kill the entire subterranean colony
- They are bait toxicants designed to be carried back to the colony by foraging workers in the soil
