Approximately 10-11 hours after spraying the exterior of my home with the Demon insecticide it began to rain. (I sprayed about 6:30 p.m. and it began raining the next morning.) Should that be enough time for the insecticide to "set" or will I need to respray?
As long as Demon WP had time to dry (1-2hours) the rain will not wash it away.
