How long do you have to wait after spraying Demon before it gets wet (if it rains)?
Demon should be applied when it is dry and should also be applied when it is not going to rain for about 4 hours or longer if possible. Once an insecticide has sufficient time to dry, usually at least 2 to 3 hours, it is considered ready for rain.
