A wasp trap at Mosaic Stadium in Regina. (Eric Anderson/CBC) The home of the Saskatchewan Roughriders, Mosaic Stadium, has become a hot spot for wasp activity in recent weeks.

The insects were especially noticed at the most recent home game, when one fan was stung and had to leave to get medical attention.

Players have also been bothered, including Riders wide receiver Rob Bagg.

"I did get stung once, actually," Bagg told CBC News. "It didn't feel very good. It was before practice. I toughed it out, you know, being a big football player."

Cornerback Paul Woldu said he has gone into some animated gyrations during wasp encounters.

"I got one actually caught in my helmet about a week ago which was really funny for everyone else that's watching and not so funny for me as I decided to rip my helmet off," he said.

Traps set out out

Wasp traps have been placed in different parts of the stadium, in an effort to reduce their numbers.

However Russell Eirich, pest control manager for the City of Regina, said the traps won't eliminate the problem.

He said wasps are attracted to an ample food supply at the stadium, found in food litter and spills from sweet beverages.

The source nests, he added, could be quite far from the stadium.

"It won't be one nest, it'll be multiple nests that could be half a mile away," Eirich explained. "To locate an individual nest is virtually impossible."
