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 BC. Commercial producers and home gardeners alike should be vigilant to help keep BC free of these potentially damaging pests. To help in this effort, report suspected finds to your nearest BCMAL office, or a regional office of the Canadian Food Inspection Agency.

The following links provide more information on serious pests that have either not been detected in BC (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 and Invasives - Prevention and Early Detection 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.
