First, though, let's talk about the study. A team at the Ohio State University, led by entomologist Susan Jones, tested five populations of adult virgin female bed bugs on the ActiveGuard fabric. The researchers weighed the bugs, put them in a petri dish with either treated or untreated fabric (the latter as a control), kept them on the fabric for one or 10 minutes, and then took them off and offered them blood from an artificial feeder for half an hour. The researchers then weighed the bugs to see how much blood they'd eaten and put them into an enclosure with a male and watched to confirm whether they'd get busy with some traumatic insemination. Then, the researchers monitored the females to see if they'd lay any eggs.
