A backpack mist blower carries a 3.7 to 4 gallon chemical tank above a gas engine and fan, and blows the spray out as a fine mist that reaches 25 to 50 ft and wraps around leaves. It covers far more ground per hour than a pump sprayer, which is why mosquito control services and orchards use them. Airflow and reach are what separate them. Several also dust powders or spread granules, and some double as a leaf blower with the tank empty. They are loud two-stroke machines that run on mixed fuel and call for hearing protection along with whatever protective gear the chemical label requires.
