B.C. to tackle fire ant invasion

British Columbia'sgrowing population of European fire ants is getting more attention from municipalities inthe Metro Vancouver area.

The Invasive Species Council of B.C. will meet with experts on Tuesdayto develop a strategy for tackling the invasive ant species, which has been inB.C.'s southern coastfor a few years.

Thethin, red ants have been found around Chilliwack, North Vancouver, Victoria and Burnaby and, unlikenative fire ants, can be aggressive.

Althoughonly four millimetres long, the ants are known to swarm and sting people and pets if disturbed, causing swelling and in some cases, emergency treatment.

Abdul Majid, president oftheBurnaby and Region Allotment Gardens Association,said his group's members are now fighting European fire antsin almost 200 community garden plots.

"We have started giving out traps and baits to our members," he said.

"We can see the spread. It's quite prevalent," Majid said.

Rob Higgins, an entomologist,has been tracking the spread of the European fire ant for more than a year.

He said thisinvasive species is aggressive, and tends to form multiple colonies close together, which can make it hard for people to use their yards, gardens or even parks.

"They kind of move sort of a dense nest profile slowly forward on the landscape but they don't like to cross paved roads.

"So you get really intense heavy infestations on one city block, but immediately across the street the residents will be completely unaware that there is a problem," he said.

Higgins said he is concerned that the behaviour of the colonies is changing for the worse.

"Now that these ant colonies, which were probably introduced a number of years ago, are starting to get large, they are becoming more aggressive," Higgins said.

Higgins said he is planning on touring the Lower Mainland to investigate other possible colonies.
