Pressurized Cans (Aerosols)
This type of sprayer consists of a sealed container of compressed gas and
pesticides. The pesticide is driven through an aerosol-producing nozzle when
the valve is activated. Pressurized cans usually have a capacity of less than
one quart (one liter) and are not reusable. Larger reusable cylinders are avail-
able for structural pest control and for some greenhouse uses.
