Control may not be immediate, but if the spray or dust is properly and thoroughly applied, it will leave a residue that will bring about control of either insect in a few weeks. Pressurized household sprays are preferable for home use. Apply the spray around baseboards, door and window casings, bookcases, shelving closets and other storage areas, and places pipes go through walls or floors. Spraying only the warmer parts of the building is usually sufficient to control firebrats. Use insecticides according to the label.
Sprays are less conspicuous than a dust and leave a better residue to provide continuing control.
