Eddie from Chula Vista, Ca writes,

When boring holes in wood to inject Boracare what diameter hole should be drilled?


Application Technique: Injection holes (typically 7/64" or 1/8" in diameter) should be drilled in the area of suspected or known infestation. Drill the holes through the widest dimension of the wood that is available. Holes should extend approximately 3/4 of the way into the beam. If the widest surface is not accessible, holes can be drilled approximately 8-10 inches apart into a narrower surface. Press and hold the injection tip firmly into each hole and inject Boracare until runoff is observed from other holes, galleries, kick-out holes, etc. You may get splash back if the wood is solid. Release the trigger, wait briefly and withdraw the injection tip. Excess solution can be absorbed with paper towels and disposed of in ordinary trash. The holes should be in a diamond pattern and be spaced approximately 4-6 inches across the grain and 12-16 inches along the grain (Figure 1). When possible, the wood should be treated one diamond length pattern beyond the immediate area of visible infestation.
