I have wood shingle siding. Instead of putting it up normally, the builder has strips of wood (about 1/2 inch) under the butt end of the shingle, so they stick out further than usual. Don't know if this was an attemp to look like (more expensive) shakes or who knows what else. (1953 house)
There are many, many gaps in these wood strips: maybe that is to allow moisture to get out? Best I can tell, there is no wall insulation and no sheething under the shingles. (From identical neighboring houses, I've seen sort of a paper barrier. Maybe those strips are meant to be nailers?
Anyway, the wasps have decided this year that they would go up through the gaps in the strips and hang out under the shingles. Problem is, there is no way to spray up in there. I've sprayed a bunch of times but they're back around the next day.
I was thinking of using a hose connected to a funnel, which I could put over a small charcoal fire (may 3 or 4 briquets). Then push the hose a little way up one of the gaps in the strips. The big question in my mind: is carbon monoxide heavier or lighter than air?
Any other ideas? I've managed to get rid of most of the other wasps around, but this bunch has found themselves a good spot.
Thanks Bill
