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.
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
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.
