Consultation on methyl nonyl ketone and its associated end-use products, Proposed Re-evaluation Decision PRVD2022-08
Health Canada is consulting Canadians on the proposal to continue registration of methyl nonyl ketone and all associated end-use products registered for sale and use in Canada.
Methyl nonyl ketone is registered in Canada for use as an animal repellent against cats and dogs in a wide range of indoor and outdoor domestic settings such as on furniture, carpets, flowerbeds, lawns, patios and garbage cans. It can be applied as a spray (indoor and outdoor), or by spreading the granular product by hand or with a fertilizer spreader (outdoor). It acts by confusing the animal's sense of smell and discouraging it from visiting the treated area.
When the current label directions are followed, these products were shown to have value in providing a pest management solution, and potential risks to human health (residential and bystander) and the environment (aquatic and terrestrial organisms and their habitats) are considered to be acceptable. Based on the current use pattern, occupational and dietary exposure are not expected. As a result of the re-evaluation of methyl nonyl ketone, no additional risk mitigation measures are proposed by Health Canada.
For a full list of products containing methyl nonyl ketone, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.
