4-Aminopyridine is a repellent used for the control of feral pigeons, sparrows, and certain blackbirds and cowbirds, in, on, or in the area of structures, nesting and roosting sites. The products are registered as restricted class and are for use by, or under the supervision of, government agencies and pest control operators only. Currently, one technical grade active ingredient and three restricted class end-use products are registered in Canada (Appendix I). The products are formulated as impregnated whole corn, corn chops or mixed grain.
After a re-evaluation of 4-aminopyridine, Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act and Regulations, is granting continued registration of products containing 4-aminopyridine for sale and use in Canada. An evaluation of available scientific information found that products containing 4-aminopyridine do not present unacceptable risks to human health or the environment when used according to the conditions of registration, which include amended label directions. Label amendments are required for all end-use products as summarized below and listed in Appendix II. No additional data are requested at this time.
- Add personal protective equipment for handlers removing unused bait and dead birds.
- List both the common names and the scientific names of target birds.
- Revise wording with respect to pre-baiting to refer to "non-target bird species" rather than "desirable or protected bird species".
The PMRA's pesticide re-evaluation program considers potential risks, as well as value, of pesticide products to ensure they meet modern standards established to protect human health and the environment. This re-evaluation decisionFootnote 1 was proposed in the consultation document, Proposed Re-evaluation Decision PRVD2016-08, 4-Aminopyridine. This decision is consistent with the proposed re-evaluation decision stated in PRVD2016-08. A reference list for all data used as the basis for the re-evaluation decision is also included in PRVD2016-08.
One comment was received during the consultation process. This comment did not refer to the pest control use of 4-aminopyridine, but to its use as a human therapeutic drug. The comment has no bearing on the re-evaluation decision on the pest control use of 4-aminopyridine, and therefore is not discussed in this document.
To comply with the re-evaluation decision, the required label amendments must be implemented on all product labels sold by registrants no later than 24 months after the publication date of this decision document.
Any person may file a notice of objectionFootnote 2 regarding this decision on 4-aminopyridine within 60 days from the date of publication of this Re-evaluation Decision. For more information regarding the basis for objecting (which must be based on scientific grounds), please refer to the Pesticides and Pest Management portion of Health Canada's website (Request a Reconsideration of Decision) or contact the PMRA's Pest Management Information Service.
