While federal law dictates that only pesticides are approved for EPA registration, the EPA oversees the regulation of devices so that they do not make “false or misleading”claims. An Establishment Number is assigned only to those that meet the EPA’s toughest requirements.
In the case of Ladybug, a large collection of peer-reviewed studies conducted in laboratories and universities across the nation validate that steam vapor systems equipped with TANCS® disinfect thousands of times better than chemical disinfectants must meet to qualify as EPA registered. The studies are published in top scientific journals and are listed here: Peer Reviewed Studies
As a result of these studies, the number EPA Est. No. 82121-WA-01 is assigned to Advap and is proudly displayed on each Ladybug steam vapor system. The number tells you in a glance that your Ladybug qualifies as a disinfection device for the EPA.
