If you want to mix up two gallons of Talstar/Nyguard you will need to add 2 fl oz of Talstar and 6ml of Nyguard in 2 gallons of water and you will need to spray this over a 2,000 sq ft area. Please note that Talstar cannot be broadcast sprayed over carpets and furniture indoors.
You can re enter after the NyGuard IGR treated area has dried. Normally about 2 hours. Like with most insecticides when applied per label it is safe for children and pets to be around after it dried.
NyGuard IGR is safe for pets to be around after it has dried.
NyGuard IGR should be diluted with water and applied with a hand pump sprayer. For both fleas and cockroaches, it is recommend to use an adulticide (insecticide) along with the NyGuard: NyGuard will not kill existing adult insects; it will only affect immature stages. An insecticide like Onslaught Insecticide would be great to use with NyGuard for roaches and fleas. You would use 0.5 to 1.0 fl. oz. of Onslaught with 8 mL of NyGuard IGR per gallon of water and apply as a broadcast spray in areas with fleas, such as carpets. For roaches, treats cracks and crevices where these insects hide or are likely to travel. Please see our Treatment Guides for these pests for more tips and information:
No, vacuuming would not affect the the residual of Nyguard IGR or any insecticide once it has been applied and dried. Please let us know if we can be of any further assistance.
NyGuard IGR should be mixed with a liquid concentrate such as Onslaught that can be applied indoors for eradicating the fleas. You can mix the two products together with water and apply once every two weeks (minimum of 2 applications). Please take a few moments to review our treatment article on How to Get Rid of Fleas. Please let us know if you need anything else.
We recommend only mixing NyGuard IGR when you are ready to treat and mix only what is needed. Once it has been mixed with water, the solution must be used or discarded within 24 hours. Before mixing, the shelf lilfe is 3-5 years from the date of purchase if stored at room temperature.
