Boracare (Bora Care) is an odorless liquid borate based insecticide-termiticide-fungicide that diffuses deeply into wood. Boracare as a termite killer is not applied to the soil, but used as a treatment of cellouse material (wood based material) directly. Boracare penetrates untreated wood to kill insects such as Powderpost Beetles, Carpenter Ants, and Termites. Boracare with Borate salts work by taking advantage of a unique feature in the biology of termites, ants and other insects. If ingested by ants, beetles or termites, the insect becomes unable to extract nutrition from its food and starves to death. And because of this unique mode of action, insects cannot develop a resistance. Bora Care is mixed 1:1 to 2:1 depending on insect and thickness of wood. It also has a label against Decay Fungi, but to prevent mold, use the Boracare with Mold-Care.
BoraCare is a liquid borate in a glycol solution, allowing a deeper penetration than another borate such as Timbor. BoraCare will last for the life of the wood, so retreatment is not necessary.
A handy tool when applying Boracare is to use a tempory marking dye such as AlG Super Marking Dye that will help you monitor spray applications.
