BARRIER PREVENTING WOOD PEST ACCESS TO WOODEN STRUCTURES |
摘要 |
A method and device are disclosed which prevent the intrusion of insects (termits, ants) into wood structures by using a barrier comprising a polymer (preferably a polyurethane) having incorporated therein a pesticide (pyrethroid or oganophosphate insecticide). The insecticidal agent may be incorporated into the polymer by itself or in association with a carrier (preferably carbon black or activated carbon) as a bound friable mix. The barrier is placed between the wood structure (e.g. a wall or windowsill) and a non-wood structural portion such as soil. In the disclosed method the barrier maintains a minimal effective level of insecticide for a predetermined period of time.
