We have an infestation of Powder Post Beetles in the rafters of our basement root cellar. We need a liquid to spray up into them and it needs to be strong enough to kill them but safe and as non-toxic as possible. What is your recommendation? Thank you for your response.
Go with the Boracare listed in our Powderpost Beetle Control article. Boracare uses a boron based active which is very safe for use around people and pets. And since the product is absorbed by the wood, there is no way anyone or any pet can get an exposure once the product dries and cures (usually takes 72 hours to fully cure).
Plus, Boracare is odorless and treatments last 5-10 years inside homes so it’s the best option for this situation. Read up on it here:
