Changes to the registration of abamectin pesticides

All pesticides used in Canada must be registered under the Pest Control Products Act. Pesticides are re-evaluated to ensure that they continue to meet health and environmental requirements. Re-evaluation may result in the revocation of a product or product uses. Health Canada may also request changes to a product's label, including mitigation measures, use sites and application methods.

Abamectin is an acaricide/insecticide used on a wide range of outdoor field-grown fruit and vegetable crops, outdoor ornamentals, and greenhouse vegetables and ornamentals. It is also used for indoor or outdoor structures to control cockroaches and ants. Highlights of the re-evaluation decision regarding agricultural and horticultural uses of the active ingredient abamectin, published on July 31, 2025, are summarized below.

Read and follow the label

All pesticides registered in Canada have a Health Canada-approved label with a registration number. Read the pesticide label carefully, as it contains specific information on how to use it.

To find the most up-to-date label, use the Health Canada online label search tool, or search for "Health Canada pesticide labels" using your favourite search engine.

Users must follow the instructions on the updated labels.

Using a pesticide contrary to the label directions is a violation of the Pest Control Products Act.
