Injection Treatment

Wood injection or "drill-and-treat" applications have been used since the 1920s to treat drywood termite infestations, which are accessible and detectable. An insecticide is injected into small holes drilled through any wood surface into termite galleries delivering the treatment directly to the pest population. This is the simplest and most direct method of termite treatment.

The amount of drilling required and the effectiveness of this termite treatment depend on the chemical used and the nature of the infestation.

Most chemicals will remain active in the wood after treatment to thwart resurgent colonies.
