Southern Ag Natural Pyrethrin Concentrate is labeled to be used as a space spray for mosquitoes. Be aware it will only kill the insects that are out in the open at the time you spray. The instructions are as follows: Dilute at a rate of 1 part concentrate to 19 parts water or oil. Apply with mechanical or compressed air equipment (non-thermal) adjusted to deliver a fine mist. Close doors and windows and shut off ventilating system. Spray direct at an upward angle distributing it uniformly through the entire area at a rate of 1 ounce per 1,000 cubic feet of space. Keep area closed for at least 10 minutes. Ventilate and sweep up and destroy dead and fallen insects before reoccupying.
