Well for the past 4 weeks I have been battling "yellow jackets" that made a nest "behind" the wood trim molding around my front door entry way. I sprayed the area over & over again for the last 3 weeks, using up "3" cans of wasp/yellow jacket spray, to no avail! A week ago, I even bought a yellow jacket "trap lure", that is supposed to lure them in & kill them, & hung it 12" away from the nest area, again to no avail.
I read somewhere that yellow jackets die off in the cold weather.
Does anyone know if in fact yellow jackets really die off in the cold weather?
