NyGuard IGR gets to the root cause of chronic insect infestations - the eggs, larvae or nymphs - and prevents them from maturing into reproductive adults thereby controlling future infestations. NyGuard IGR will cause morphological anomalies or changes and disrupt the expected insects' state of development, leading to sterility or death. When adults are present, NyGuard is commonly used in combination with a non-IGR insecticide. This method results in rapid eradication of adults and deposits a base level of NyGuard IGR. Since this product has a long residual, it remains in place for up to seven (7) months to actively disrupt the development of any immature stages that have yet to appear, or which were not susceptible to the insecticide product used to control adult insects.


  • NyGuard IGR has the broadest spectrum of insects on its label.
  • NyGuard IGR is 10 times more active than Gentrol.
  • NyGuard IGR is effective both indoors and outdoors.
  • NyGuard IGR may be used in food and non-food areas.
  • NyGuard IGR keeps working for seven months.


Apply NyGuard as a diluted spray or ULV/fogger to prevent eggs, larvae and nymphs from maturing into reproductive adults. Apply NyGuard in combination with a non-IGR adulticide to knockdown and kill existing adult populations while breaking the cycle of your toughest insect pests.
