VANCOUVER -- Enduring 180,000 bites is the scientific price a British Columbia biologist had to pay so her team of researchers could suck a little life out of the worldwide bedbug epidemic.

A team of biologists, a chemist and students from Simon Fraser University in Burnaby, B.C., announced Monday that they have identified a set of chemicals that can lure bedbugs into traps and keep them there.

The findings are significant because the pests, which were once thought eradicated in industrial countries, have reappeared over the past two decades, infesting everything from low-income housing to pricey hotels and causing health concerns, too.

Biologist Regine Gries, who with her husband Prof. Gerhard Gries, form part of the team, said she was initially a little reluctant and disgusted to act as a host so the pests could feed and scientists could gather and analyze the bugs skin and feces.

She said she got over those feelings because she, unlike others, was resistant to the bites.

"I calmed myself down thinking when human beings were still living in caves, they were probably bitten by bedbugs, by fleas, by mice and who knows what, all these insects associated with humans," she said. "So I think humans can endure this, and I'm lucky enough that I have no side effects, that I just can handle it."

Not only can bedbug bites cause rashes and itching, but a recent study linked them to Chagas, a disease that can cause serious heart and digestive problems in those who are infected, said SFU Chemistry Prof. Robert Britton, who is also a team member.

The team is now working with a company based out of Victoria, B.C., to develop the first effective and affordable trap to detect and monitor infestations.

The discoveries were made in three separate phases and began when the Gries and their students began the research about eight years ago.

Scientist endures 180,000 bed bug bites to help develop trap

VANCOUVER -- A British Columbia biologist has endured 180,000 bites with the intention of sucking the life out of the worldwide bedbug epidemic.

Once thought eradicated in industrial countries, the pests have reappeared over the past two decades, infesting everything from low-income housing to pricey hotels.

A team from Simon Fraser University in Burnaby, B.C., including biologists, a chemist and students, has now identified a set of chemical attractants that lure the bedbugs into traps and keep them there.

But those findings required biologist Regine (reh-GINA') Gries, who is immune to the bites, to act as a host so the pests could feed while scientists gathered skin and feces from the bugs to analyze.

The team is now working with a company based out of Victoria, B.C., to develop the first effective and affordable trap to detect and monitor infestations.

SFU Prof. Gerhard Gries, the husband of Regine, says the trap will help landlords, tenants and pest-control professionals to determine whether a premise has a bedbug problem.
