More information about our sprays

The Sioux Falls Mosquito Control program uses the product Zenivex E20, mixed with a carrier oil for our spray events. In an effort to bring clarity to the amount of product that is actually being emitted during these events, we have broken it down a bit.

We have our spray equipment droplet tested and calibrated each spring to ensure proper applications as per their label requirements. The mid-level application rate of Zenivex E20 is 0.0627 fluid oz/acre. As the name implies, Zenivex E20 consists of 20% Etofenprox (a type 3 pyrethroid) as its active ingredient. The remaining 80% are inert ingredients and are meant to serve as carriers.

If our application rate is 0.0627 fluid oz/acres, then only 20% is actual pesticide, so – only 0.015 fluid ounces of active ingredient are being applied per acre.

              For comparison purposes, 1 tsp = 0.166 oz

Because a mosquito’s body mass is so small, this minute amount is all that is necessary.
