European Fire Ants fact sheet
European Fire Ants were discovered at VanDusen Garden a few years ago and some areas along the Arbutus corridor are already infested. These ants are aggressive and can deliver a painful sting when disturbed, though this rarely leads to allergic reaction needing medical treatment. They establish and spread colonies rapidly, and do not have obvious mounded nests, which makes them difficult to control.
European Fire Ants can be easily transferred through the movement of infested garden material. To help prevent the spread of these ants, avoid sharing soil, mulch or plants with others. As well, be sure to check newly purchased plants and soil before introducing them to your garden.
Please take a moment to read this fact sheet produced by VanDusen Botanical Garden, Bloedel Conservatory and Vancouver Parks and Recreation which gives detailed information on how to identify and prevent further spread of European Fire Ants.
