The water that Boracare is mixed with will eventually evaporate, and it will dry. You could also wash the product off the tarp and reuse it.
Boracare is too thick of a product to be used in any type of fogger. It can be foamed into wall voids or sprayed or painted directly onto raw untreated wood only. If you cannot directly access the wood that needs to be treated, foaming is the best solution, although it will only penetrate into wood that it is directly contacting.
When treating an active infestation, Bora Care should be used at a 1:1 ratio on raw wood. It appears that the product may not have been applied at the correct rate to get control of the active infestation. Please be sure to review the product label for more information and complete application instructions. Also, please take a moment to review our Powderpost Beetles article here for more information on this pest. Boracare will last for the life of the wood but will only kill the beetles that are active and feed on the wood so you can still see activity as they can lay dormant for years until conditions are right for the young to hatch and become active.
When you apply Bora-Care, it is best to allow it to fully dry before being in the same room as the treated wood.
Drying times after Bora-Care can vary depending on the thickness of the lumber, humidty and air temperatures. It’s recommended to allow 72 hours for the Boracare to completely dry before sanding, painting or staining the wood. Once the application has completely absorbed throughout the wood and dried, there should not be any sticky residue left on the surface. Lumber that is greater than 10 inches thick do require 2 applications or if only 1 or 2 surfaces of the wood can be treated.
Please refer to the Lumber Bulletin and the Bora-Care Total Wood Preservative for Use Prior to Installation of Lumber Section on page 13 of the product label for more information.
Boracare can be used on ANY raw wood that is not painted, stained, or sealed. Since it dries on clear, there should be no problem with stain, paint, or seal when you are done or while applying a clear coat finish. Please view the full product label for more information.
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.
Bora-Care should be applied uniformly and evenly on all sides of raw wood either by spraying or painting on as directed on the label.
Bora-Care does not remove moisture. It is labeled to treat raw wood for the following: Wood Destroying Fungus, Termite Control and wood-destroying insects such as termites, carpenter ants, powderpost beetles, etc.
