Which, in your opinion is more a effective IGR?
Archer Igr and Nyguard Igr are both very effective IGRs. The biggest differences between the two is the ability to hold up to sunlight outdoors. Archer is photostable for 14 days where as the NyGuard is photostable for 4-6 months. NyGuard also has a wider range of pests that are covered by its ability to sterilize and inhibit the reproductive cycles.
