Starting August 1, 2020, all pesticides containing the active ingredient carbaryl will be designated as restricted materials in California, except for baits labeled only for agricultural use.
After August 1, 2020 it will be unlawful to possess or use carbaryl products without an appropriate pesticide applicator license and permit. This includes home gardeners and maintenance gardeners (if they are not licensed to apply pesticides). There will not be a sell-through period for existing products on retail shelves following the effective date.
Consumers should contact their state or local hazardous waste disposal program or local solid waste collection service for proper disposal of unused products and containers. It is illegal to dispose of carbaryl products in sinks, toilets, storm drains or any body of water.
