Pheromones lure bedbugs into a trap where chemicals immobilise them A cocktail of six different chemicals was needed to make an effective lure Researchers hope to have commercial trap available within the next year Wife of scientist leading the study acted as the host who fed the bedbugs during tests with her own blood She believes she has been bitten 180,000 times in the hunt for the lure

They are among the most dreaded and persistent pests to invade our homes, but groundbreaking research has provided a new way to combat bedbugs.

Scientists have discovered a set of pheromones, the chemical signals given off by insects, that can lure bedbugs into traps.

They have also identified an extra component that can then, crucially, keep the biting insects in the trap and away from their human food.

Bedbug infestations cause misery for millions around the world but scientists have developed a new lure that can trap the insects by mimicking pheromones that the parasites release to signal they are in a 'safe haven'

No more itching! Scientists discover a 'cocktail of chemicals' that lures bedbugs into traps - and keeps them there

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.
