Formulated with a concern for the environment, Tim-bor is used for the control of carpenter ants, drywood termites, wood decay fungi and wood boring beetles. As water soluable borate powder, Tim-bor diffuses into the wood and acts as a wood insecticide, fungicide and preservative. Tim-bor won't break down over time like most organic compounds, therefore offering longer lasting protection. Best of all, Tim-bor is easy to mix, virutally odorless and has no known resistance.
