I have a bay window extending out over my deck and I have noticed wasps regularly entering and exiting the ventilation space between the gutter and the shingles. My wife, not a big fan of insects/wasps, told me to get in the attic and do some spraying or else, which I promptly did last fall (she may be small but she can pack a mean bite, wife not wasps). After venturing into the attic and finding a half dozen or so paper wasps nest (all small but some about 2 inches in diameter), I sprayed them all and then returned later to knock down the dead nest. The spring, the wasps are back and the wife is not to happy about it. I ventured up in the attic again to doing some killing and found that a lot of the nest were in the same general location as last fall. Is there anything I can put in the attic to repel the wasps? I read about Sevin dust but am unsure if that would work as a repellent. Any suggestions would be much appreciated.
