I've noticed for several weeks that a wasp-like insect is boring holes in my wood. The only species it is working on is the hedge, which was split and stacked last November. They bore a hole about 1/4" across and burrow into the wood. I tried to get a picture but, being wasps, they wood not land long enough to capture them digitally. They are about half the size of the typical wasp and are dark blue to black in color. I plan to spray anyway, as the are producing alot of fine sawdust. Very curious as to why the hedge only.
