Consultation on (Z)-9-tricosene and its associated end-use products, Proposed Re-evaluation Decision PRVD2022-07
Health Canada is consulting Canadians on the proposal to continue registration of (Z)-9-tricosene and all associated end-use products registered for sale and use in Canada.
(Z)-9-tricosene, also known as muscalure, is used for the control of flies and acts as a fly attractant. It is a semiochemical that is produced by the female house fly, Musca domestica. (Z)-9-tricosene commercial end-use products are registered for use in and around animal/livestock housing or in residential/commercial structures and inside transport vehicles. The commercial class end-use products are co-formulated with conventional insecticides and are available as bait stations, sprays or brushable paint. The domestic class end-use product is not co-formulated with any other insecticide and is registered for outdoor use around residential and farm buildings to reduce fly populations using physical traps.
(Z)-9-tricosene has a non-toxic mode of action and has value in providing a pest management solution. Based on the current use pattern of (Z)-9-tricosene, dietary exposure is not anticipated. The potential risks to human health (occupational, residential, and bystander) and environment (terrestrial and aquatic organisms) are considered to be acceptable when products containing (Z) 9-tricosene are used according to label directions. As a result of re-evaluation, no additional mitigation measures are proposed.
For a full list of products containing (Z)-9-tricosene, 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”.
