We have German roaches in our yard from a used piece of furniture sitting on the curb. I am 100% sure they are German. I am using Cyper WSP monthly on the perimeter of the house but want to get rid of them in the yard as much as possible. I would like an insecticide that will last as long as possible in the elements. I would appreciate knowing application rates for both products (the Nyguard IGR and insecticide) and also how often to apply both (either separately or together). Thank you!
Cyzmic CS is a great option for use in your lawn for German roaches. This can be mixed with Nyguard IGR and sprayed at the same time. The mixing rate is 0.4 fl oz per gallon of water. This will last for approximately 30 days outdoors and can be reapplied every 21 days.
