I cut down up my neighbor's redbud after it fell during a storm, and when the two trunks split these little wood burrowing beetles were scurrying away. I'd hate to try to cut out that section of the tree and burn it unless that was last resort because I got the wood for turning and I'd lose some sections that seem like they would be uniquely figured. I sprayed with some stuff that I got to kill termites in my barn because it said it would kill powder post beetles and such, and then I covered it with a tarp. Think this will work?
