What do I use for Powder Post Beetles and how much for 2500 square for house.
I had a company drop a tent over my house and Deck to fumigate it for powder post beetles. From what I can tell they are still there, or new ones have taken their place. Does this product kill these things and keep them at bay for a while. If so how much do I need, how often to use it and what climate conditions, is it safe.
We are not very familiar with the process of tenting a home and how it affects the powder post beetles, their larvae thats in the wood, and if it prevents at all or just kills the ones within it. This would be a question you would definitely want to consult with the company that did the treatment on to find out how their treatment was supposed to work for your home. Typically if a customer was not tenting their home and had powder post beetles somewhere within it, you would only treat the wood that has them currently in it with a product like Boracare. Boracare is a wood treatment product that will absorb all the way into the wood and will kill any insects that are currently infesting it as well as last for the life of the wood to protect it from any future wood destroying insects like powder post beetles and termites. Boracare must be applied to raw wood only though so you cannot apply it to any beams or wood that has been painted, stained or finished in any way as it will not soak into the wood. If the wood you need to treat has paint or some finish on it, you would either need to remove it by stripping it or sanding it and apply the Boracare to the raw wood before refinishing it, or use a product like Jecta which is for sealed wood and is drilled and injected into the wood. Even after applying a product like Boracare to all sides of the infested raw wood (ideal situation) you can often still see signs of activity of the powder post beetles for a few years after treatment. This is because the product works through ingestion so as the larvae emerge from the wood (which is whenever they are good and ready) they eat the wood on their way out and ingest it and die. No new adults will be able to leave them in any holes in the wood as again, once they ingest it they will die. Normally tenting is used when the whole home is so infested with Powder Post Beetles that treating with products like Boracare and Jecta would be unreasonable.
