It is important to note the difference between application techniques for mosquito control before selecting which product to use. ULV fogging works by compressing the insecticide through a specially designed nozzle. This produces a very fine mist. Applications made in this manner are great for quick knock-down but do not tend to offer any residual control. Misting from a backpack would allow you to use a product with more residual control. This type of application will produce a larger droplet size than “fogging” and will wet surfaces where product is applied. There a many products labeled for each of these application methods. Please contact your local Target Specialty Products’ Location for more information on these products.
