Bill from Texas writes,

Can Nyguard be mixed with Demand CS?

I am spraying a barn with a large infestation of spiders, ticks, flies, etc, with a one gallon B&G sprayer. Can I mix Nyguard with Demand CS for the best knockdown and control?


Yes, Nyguard IGR can be mixed with Demand CS. However, Nyguard IGR is an insect growth regulator. It is like a birth control for certain pests. It does not help with the knockdown of the pests. You will use 1 fl. oz. of Nyguard IGR with a gallon of water. For a severe infestation, you will use 0.8 fl. oz. of Demand CS.

If you are looking for a product to get a quicker knockdown, we would recommend ExciteR Pyrethrin Concentrate. ExciteR Insecticide with piperonyl butoxide (PBO) was designed with a pyrethroid pesticide to amplify the efficacy on pest insects.

Please let us know if you have any additional questions.
