Jim writes,

Can Permethrin SFR be used to refill the commonly sold mosquito treatment agents that attach to a garden hose?

If so, how much product would you put into the bottle before topping of with water?


Hose end sprayers are all calibrated differently. For instance, the particular sprayer you have may be calibrated to spray 1 ounce of product per 1 gallon of water but another brand may be calibrated to spray 3 ounces of product per gallon of water. The problem with pre-filled hose end sprayers is that you have no way of knowing how it is calibrated. We recommend that you purchase a new hose end sprayer that is adjustable. We have a great model available on our website called the Chapin Liquid Hose End Sprayer Model 6005. Permethrin SFR is only labeled for mosquito control on livestock premises. A better product for mosquito control outdoors is Talstar P. Talstar P is gentle on vegetation where you will be spraying for mosquitoes and it will last up to one month for mosquito control. When using Talstar for mosquito control, you will use 1 oz of product per gallon of water.
