No, NyGuard IGR Concentrate is rainfast after about 6 hours therefore if it lightly rained 2 days later, the application should be fine. Typically, NyGuard IGR will hold up for a couple months in outdoor elements between treatments. IGR’s should be mixed with an insecticide for complete control of the insects as IGR’s only stop the reproductive cycle of insects, it does not kill them. The insecticide, depending on the product would need to be reapplied approx every 30 days. Refer to the insecticide product label for retreatment intervals.
