If you discover where the wasps are nesting, they are most vunerable after dark and in the early morning hours. They roost overnight and need to warm up before their intense daily activities begin. The best time to spray a nest site is when all the members have returned to roost, and especially early in the mornings before they've had a chance to warm up. I have several bird houses that must be cleared on occasion because of the aggressively territorial buggers. Raid Ant & Roach in the red can works well for this - once the wasps are cleared out, the house must be cleaned of residue before making it available to the birds again. Bob Santangelo Wheat Ridge
