Bed Bug Bully kills some bed bugs, according to research from Rutgers New Jersey Agricultural Experiment Station. A 2013 study determined that 60 percent of bed bugs sprayed with Bed Bug Bully died within 10 days. The natural product's active ingredients include mint, clove, citronella and rosemary oils.
The Rutgers study used laboratory conditions to test how well Bed Bug Bully kills bed bugs. Researchers placed the insects on filter paper in plastic containers before spraying the bugs and transferring them to clean dishes. Researchers believe that bedbug mortality is likely to be lower under normal household conditions.
Outside of the lab, bed bugs tend to hole up in cracks, crevices and other hiding spots. In these cases, the spray does not directly hit the insects. Any significant impact is lost because the natural ingredients of the product have little effect once dry.
