Canada to end some propoxur uses
The Canadian Pest Management Regulatory Agency (PMRA) is to phase out certain uses of the insecticide, propoxur, because they are no longer supported by registrants or because risks to human health have been identified. They include control of biting flies, use in pet collars, all indoor uses of domestic class products except bait trays, and indoor uses of commercial class products in residential areas. The insecticide will still be allowed for use as a crack and crevice treatment, outdoor uses of domestic and commercial products, and in bait trays. Excluding fumigants, there are few alternative active ingredients to propoxur approved in Canada for broad-spectrum control of structural pests, the PMRA notes.
