I have a crack in my porch and have seen several hornets come in and out. Will spaying inside the crack without knowing exactly where the nest is kill them?
Tempo 1% dust is one of the most effective products to treat for hornets. If you are seeing hornets coming in and out through cracks you should apply the Tempo 1% Dust with a duster such as the B&G Bulb Duster 1150 and direct the dust into the cracks where you are seeing the insects enter and exit. Be sure to treat in the times of the day when they are less active (earlier morning or later evening).
