Active termites within the wood
Boracare works by ingestion. Boracare will not be carried back to the colony. You can inject a product with a transfer effect such as Premise Foam directly into the wood to kill the existing termites and also the termites back at the colony. After 90 days you can then treat the wood with Boracare to protect it from future infestations.
