NyGuard IGR and NyGuard EZ1 IGR use the same active ingredient, have the same mode of action and can be used for the same pests and use sites. However, NyGuard EZ1 IGR is a different diluted formula for 1 ounce single dose easy mixing.

Yes, NyGuard IGR can be used in conjunction with an adulticide insecticide as directed on the label. Always read and follow the label instructions.
