(Continued) We are still seeing post beetles in our barn a couple years after applying Boracare. I wasn't sure if they were newly hatched beetles or new adults coming in from the environment. The Boracare was used on posts in an old barn so the wood wasn't sealed in any way after the spray was applied. Is it normal to see beetles year after year despite thorough application of Boracare? Also, what is the best time of year to apply Boracare? We applied in late June/early July but can it be used in the fall with the same success?
BoraCare can be used anytime of year as long as the wood itself is not damp or high in moisture. To ensure your BoraCare application lasts the entire life of the wood, it is recommended to apply a water sealant, stain or paint within 30 days of the application.
The beetle activity you are seeing could be new beetles coming into the barn. We would recommend inspecting the wood inside the barn for any holes or debris to determine if there is activity inside the wood that has been treated.
If reapplication of BoraCare is determined necessary, we would suggest applying a paint, stain or sealant within 30 days to ensure the life of wood protection.
