How to Use
- Step 1: Determine how much Demand Duo Insecticide to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). For outdoor perimeter applications, use 12.8 fl. oz. to 1 gallon of the diluted Demand Duo solution per 100 sq. ft. For general indoor and outdoor pests, apply 1.1 fl. oz. of product per gallon of water. Refer to the product label for specific application rates and restrictions.
- Step 2: Fill the spray tank with half the amount of water, add the proper amount of product, then pour in the remaining half of the water. Close the tank lid and agitate until the solution is mixed.
- Step 3: Spray the foundation 3 feet up and 3 feet out on adjacent ground for perimeter applications. For spot treatments, adjust the sprayer nozzle to deliver a coarse spray and treat surfaces covering an area no larger than 2 sq. ft.
Where to Use
Demand Duo Insecticide can be used in, on, and around residential, institutional, public, commercial, and industrial buildings.
Do not apply this product, by any application method, to linden, basswood, or Tilia species.
