How long should I wait between treatments of Tim-bor on my barn walls and floor as I try to kill PowderPost Beetle
The PowderPost Beetles have moved into all floors, walls and ceilings of my 100-year-old barn. I've sprayed everything once. How long should I wait before doing a second spraying?

The rule of thumb on Timbor is 2 applications. The second application whenever the first application has completely dried. Keep in mind that Timbor will only soak about 1/2 inch into wood. Bora Care will penetrate about 2 inches. You may need to use Bora Care on some of the thicker wood, beams, etc. Also, Bora Care only needs 1 application.
