Non-Native and Invasive Pests

There are many non-native, invasive pests that threaten British Columbia's economy, including the agriculture and forest industries, and the environment. Prevention, early detection, control or eradication of these pests is key to preventing their establishment in B.C. Commercial producers and home gardeners alike should be vigilant to help keep B.C. free of these potentially damaging pests. To help in this effort, report suspected finds of new invasive pests or diseases to your nearest Ministry of Agriculture office, or a regional office of the Canadian Food Inspection Agency. Report invasive plants to the B.C. Ministry of Forests, Lands and Natural Resource Operations, Invasive Plant Program.

The following links provide more information on serious pests that have either not been detected in B.C. (e.g. Plum Pox Virus), or are present but not widely distributed or under official control programs (e.g. gypsy moth). Also refer to the factsheets Invasive Alien Species - No Rest from New Pests (PDF, 654 KB) and Invasives - Prevention and Early Detection (PDF, 465 KB) for more information on the threat of non-native pests, and the factsheet Biosecurity Guidelines for information on protecting farms from introduction and spread of plant pests and diseases.
