armor guard before afterfive star Paul P in TN (1/3/17) - "Powder Post Beetles dead! I built a porch on my home 3 years ago. On the porch, I built cabinets using old barn wood that I had heated to kill bugs. A year or two later, I started seeing little piles of sawdust on my counter tops. Sunday, I mixed up some Armor Guard and water and put it into a Cajun Injector that I use to marinade meat and injected the solution into those tiny holes. It really went into the wood well in some areas. I really did not expect a very good result, but you can see by the pictures that I killed the crud out of those little buggers in less than 24 hours. I guess by injecting the solution I got it right to their food source, they ate it, and died!"




five star R Walker in MN (08/3/14) - "Armor Guard is a fantastic borate product. I had a higher coverage rate than I expected on my cabin at an affordable price!"

five star D Clausen in TN (06/14/14) - "My wife and I knew we needed to apply a preservative, but we were crunched for time. We only had a couple of days to get the job done and using the Armor Guard we were able to start staining the following day. We sleep better knowing that we have some type of protection on the logs."
