Regine Gries has been bitten by more than 1,000 bedbugs each week for the last five year and she allowed it to happen.

In fact, Gries welcomed the 180,000 bites.

Now her literal blood sacrifice has paid off. She and her husband Gerhard, both biologists at Simon Fraser University in Vancouver British Columbia, say they have figured out how to attract and repel the bloodsucking parasites.

It turns out bedbugs communicate by odor. The researchers have been able to identify that histamine effectively repelled the creepy creatures.

They also discovered five odors that attract bedbugs and could be used to draw them into death traps.

That’s where Regine Gries blood comes back into the story. She sacrificed her own skin night after night as part of the experimentation process to feed the bugs they were using in their research.

But her blood, sweat and probably tears may all have been worth it for people plagued by the beasts.

A Victoria British Columbia company, Contech Enterprises, is now developing what is being called the first affordable bait and trap for detecting and monitoring infestations.

Contech expects it to be commercially available next year.
