I am going to place an order for the Viper Cypermethrin and I have 2 questions about the product. Does it have an expiration date/shelf life and what strength do you recommend for kudzu bugs? Thanks, Jeff
In general, most all of our products will last at least 5 years when stored in a cool, dry environment like a closet or basement. Viper is no different. So when purchasing, we recommend not getting more than you expect to use in 3-4 years. This insures it will be fine and yet still allow you to take advantage of the economies of scale (the larger the size, the less it will cost per oz).
Now when treating for kudzu bugs, it’s best to start using it at the rate of 1 oz per gallon of water per 800 sq/ft of surface area being treated. This would be what we call the “cleanout” rate. Once they’re gone and you’re only treating for “maintenance” (to make sure they don’t return), use 1/2 oz per gallon.
