Consultation on Formic Acid and Its Associated End-use Products, Proposed Re-evaluation Decision PRVD2022-15

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of all products containing formic acid registered for sale and use in Canada, with proposed label updates.

Formic acid is a miticide registered in Canada for the control of tracheal and varroa mites and used for the treatment of honey bee colonies. Treatment of a hive with formic acid results in the diffusion of vapours through the hive, which target and suffocate mites. The commercial end-use product is applied as a liquid formulation poured onto absorbent materials (such as paper and wood pulp), or pads are pre-soaked and placed into honey bee hives. Domestic end-use products are applied to hives as a liquid formulation poured onto absorbent materials/applicator pads, or as pre-formulated slow release pads/gel strips. As a result of the re-evaluation of formic acid, label updates are proposed to meet the current labelling standards.

For a full list of products containing formic acid, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

For more information on the proposed decision open the "Proposed Re-evaluation Decision".
