How much area the gallon of Pyrocide 300 (3% Pyrethrum Fogging Concentrate) will cover depends on the rate used and the pest and area you are treating for. Complete intructions and rates are on the product label.
The product label for Pyrocide 300 indicates to apply at the rate of 1 fluid ounce of concentrate per 1,000 cubic feet of space, filling the room with mist. Vacate treated area and ventilate before re-entry. When mixing add the concentrate first, then dilute with oil, then agitate.
