Has anyone had problems with powder post beetles excavating their firewood ? I find major infestations whether the wood is stacked on gravel under a shelter or just stacked outside under a tarp. They don't consume much wood, but it makes a huge mess trying to move it around inside the house. Most of my wood is pecan with a small amount of oak, cherry, and even some pine. The pecan and oak get the beetles. Does anyone know how to prevent this mess ?
