Insect Growth Regulators (IGRs) are ideal for use against insects like cockroaches that are notorious for developing insecticide resistance. When baiting for cockroaches, incorporate an IGR like NyGuardⓇ Insect Growth Regulator into your program and apply near or into suspected harbourage areas, behind appliances, under sinks and cabinets, etc. The IGR will interrupt the life cycle of cockroaches, resulting in enhanced control. While customers may see adult cockroaches that look abnormal (twisted wings) following treatment, these insects will be incapable of reproducing.
