Kenneth from New Orleans Louisiana writes
Tim-bor Professional can be used in a foaming application (with a foaming concentrate and foaming sprayer) but is best for prevention more than active infestation as it only penetrates up to 1/4 inch into the wood it is applied to when used wet. If you are foaming for active you should drill directly into the wood they are infesting and foam into the gallery where they actively are. Be sure to review the product label for complete instructions.
