Per the Nyguard IGR product label instructions you can use varying rates. You use anywhere between 4 ml - 12 ml per gal and then apply over 1000 - 1500 sqft. Talstar is mixed at 1 oz/gal and that generally covers 1000 sqft so when mixing with the NyGuard IGR you would want to use 3 ml up to 8 ml with that 1 gallon of Talstar. In general your first application should use the higher rates.
NyGuard EZ1 typically dries within 30 minutes to 1 hour.
Once mixed, NyGuard EZ1 should be used within 24 hours. Unmixed solution should be stored in a termperature controlled environment and out of direct sunlight.
Any leftover solution of NyGuard EZ1 can be poured out outside along the foundation of the home or you can spray along the foundation to help with insects outside. The product does not reconstitute later if the carpet is shampooed so you can dispose of the dirty water as you normally would.
Insect Growth Regulators like Nyguard IGR will not cause non-repellents to become repellent when used per the product label.
NyGuard EZ1 does not kill any roaches so should not be used alone. It will only prevent the young from maturing into reproducing adults.
Nothing can replace a good sanitation system so be sure that the restaurant, especially the kitchen, is being cleaned thoroughly as often as possible. We would still recommend reading over the guide here. Patience is key when it comes to a roach control treatment, be sure to follow the labels when using insecticides to get the best results and eliminating other food sources is important so they can eat the bait. We would recommend mopping with Nibor-D, it has been a tremendous help with restaurant owners.
How to treat for roaches in a restaurant:
When dealing with roaches, treatments should be limited to cracks, crevices and wall voids as this is where roaches spend most of their time. Using a combination of roach bait, insecticide, and an insect growth regulator will usually be needed.
Per the product label: one treatment works for 6 months against hatching cockroaches. Please keep in mind that NyGuard EZ1 does not kill any roaches so it should not be used alone. It will only prevent the young from maturing into reproducing adults. We would recommend using one of our Roach Control Kits instead for the best results.
