William from Margate, Florida writes

What happens if I use a non-repellent and an IGR, such as NyGuard IGR, on roaches?

Why do they scatter if it is a flushing agent? Do NyGuard and Alpine WSG act like a flushing agent when mixed?


NyGuard IGR and Alpine WSG are not considered flushing agents. Alpine WSG (water-soluble granule) is a non-pyrethroid, non-repellent broad-spectrum insecticide that uses the active ingredient Dinotefuran. NyGuard IGR is an Insect Growth Regulator which is like a kind of birth control for insects. It will stop the roaches from being able to reproduce and mature further into their lifecycles. The combination of an insecticide and an IGR is recommended when dealing with pests like roaches. Nyguard IGR can be added to Alpine WSG with no negative side effects. For more information on treating roaches, please review our article on How to Get Rid of Roaches for more helpful tips.
