Invasive insects and spiders
Invasive insects and spiders are insects and spiders from one part of the world that are transported or migrate beyond their natural range and become established in a new area where they can cause potential harm to native ecosystems.
There are 5 priority categories for insects and spiders which determine the province's response. They are:
- Early detection and rapid response (EDRR)
- Provincial containment
- Regional containment/control
The insects and spiders on this page are organized into these categories.
Species is high risk to B.C. and is new to the Province. Management objective is eradication.
Asian long-horned beetle (PDF, 996KB)
Asian Giant Hornet (PDF, 331KB)
Gypsy moths(Asian and European)
Species is high risk with limited extent in B.C. but significant potential to spread. Management objective is to prevent further expansion into new areas with the ultimate goal of reducing the overall extent.
Apple maggot (PDF, 528KB)
Species is high risk and well established, or medium risk with high potential for spread. Management objective is to prevent further expansion into new areas within the region through establishment of containment lines and identification of occurrences outside the line to control.

Tropical stinging ant
Species is more widespread but may be of concern in specific situations with certain high values - e.g., conservation lands, specific agriculture crops. Management objective is to reduce the invasive species impacts locally or regionally, where resources are available.
