Are Bug Bombs Safe?
The EPA says the aerosol propellants in total release foggers, often called bug bombs, typically are flammable, so improper use may cause a fire or explosion, and that failing to leave during fogging or reentering without airing out may result in illness. It says accidents are most likely when large amounts of fogger material reach an ignition source such as a flame, a pilot light or a spark from an appliance that cycles on and off, and recommends placing foggers six feet or farther from all ignition sources.
Injuries are common enough to track. A CDC report identified 466 fogger-related illnesses or injuries from 2001 to 2006, often from failing to leave before the fogger discharged, reentering too soon, using too many foggers for the space or not warning others, and said foggers pose a risk of acute, usually temporary health effects for users and bystanders. After the EPA called in March 2010 for label changes to address the most common causes of exposure incidents, due by September 30, 2011, a 2018 CDC report counted 3,222 acute cases in 10 states from 2007 to 2015 and found no statistically significant drop in the first 3 years after the new labels took effect.
The CDC says more comprehensive strategies are needed to reduce these illnesses, including promoting integrated pest management and finding better ways to get users to read and follow label instructions.
