The gel-pack formulation of formic acid is expected to minimize the potential for dermal, eye and inhalation exposure for pesticide applicators. However, because of the corrosive nature of formic acid, and potential for eye, skin, and mucosal irritation, the Agency is requiring stringent precautionary labeling. Exposure and attendant risks are expected to be negligible for applicators when they wear appropriate personal protective equipment and follow directions for use. EPA has also examined the potential for formic acid residues to appear in honey and beeswax. When the product is used as directed, residues above those found naturally are not expected.
Formic acid is approved for use as a pesticide solely within honeybee hives.
Because of this limited use, the Agency does not expect environmental residues to occur outside the hive. FOR-MITE TM is the only registered pesticide product containing formic acid as an active ingredient. Contact the Regulatory Action Leader listed above for further information.
