I think it was rfs who told me this awhile back, but alot of house fires are started by clogged dryer vent ducts. People never think to clean them.
I usually take my duct off a couple times a year and clean it out. Last year I had a grand ole time. It seems the trap door, on the outside wall of the house, that covers the dryer vent exhaust was an ideal location, according to the hornets, to build their home. They had it plugged up really good.
I was out there with the garden hose, hornet/wasp spray, and a fly swatter doing battle. And they were those real aggressive little buggers too. I had a huge pile of hornet carcasses lying on the ground.... and I only got stung 2-3 times in the process.
