How to Stop Wood Boring Beetles Using the Screwdriver Frass Test

Subscribe to Grandpa Isaac:    / @isaachostettler   This method for finding and treating wood-boring beetle damage uses the Screwdriver Frass Test to identify active infestations in your home's structural timbers. By applying a disodium octaborate tetrahydrate mineral salt solution, you can create a protective barrier that stops larvae from further compromising your home's framing. ✅ Identification: Tap beams with a screwdriver handle and use black paper to catch fine white dust or frass. ✅ Assessment: Use the metal tip to check if the timber is still firm or has become a compromised, hollow shell. ✅ Preparation: Clean away dust and debris to ensure the mineral salt can penetrate the grain of the raw wood. ✅ Treatment: Apply a solution of one pound of borate powder per gallon of water to ensure deep absorption. ✅ Verification: Wait 30 days and re-test with black paper to confirm the reproductive cycle has been successfully broken.

This treatment is only effective on raw, unpainted wood and must not be used on firewood or surfaces that contact food. If a beam is soft, spongy, or sags under pressure, the wood has lost its structural integrity; stop and consult a professional carpenter or structural engineer to determine if reinforcement or replacement is required.
