The Aprehend biopesticide developed by Penn State researchers contains Beauveria bassiana, a natural and indigenous fungus that causes disease in insects but is harmless to humans. When a bedbug crosses a sprayed barrier, it picks up the fungal spores, which germinate and colonize the body, killing the bedbug in four to seven days.
