We currently use Talstar P and treat every 21 days.
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.
