How often exactly that you need to treat wtih Demand CS + Archer Multi-Pack will depend on the pest pressure in your area and at what rates you apply the Demand CS. In areas of high pest pressure, you may need to apply as frequently as once every 30 days. However, if you are using the higher rate of 0.8 oz. per 1,000 square feet, then one application may last 60-90 days. Please see the Mosquito Application directions of the Demand CS product label for full details and rates.
Talstar P should be applied no more than once every 28 days for mosquito applications.
We suggest you apply Demand CS + Archer Multi-pack with a hand pump sprayer.
It is not usually required/recommended to use a surfactant with Demand CS + Archer Multi-pack.
Demand CS is diluted at a rate of 0.4 to 0.8 oz per gallon of water and Archer IGR is diluted at a rate of 1 oz per gallon of water. Each gallon of solution will treat approximately 1,000 square feet. So the 2 quarts of Demand CS in the Demand CS + Archer Multi-pack will make from 80 to 160 gallons of solution and the 5 pints of Archer IGR will make up to 80 gallons of solution. You can mix both products in the same gallon of solution and you will have enough to treat an area of 1.5 acres at least one time with both products if you wish to use the IGR in all that area and not just around the perimeter of your home.
