This process is commonly used for the treatment of drywood termites and/or bedbugs, using sulfuryl fluoride as the pesticide (sulfuryl fluoride is a naturally occurring gas, used in much higher concentration than found in the natural atmosphere ...
Physical termite barriers are free of pesticides and physically block termite foraging activity. Development of physical barriers to effectively exclude subterranean termites makes it possible to design and build structures with a far lower possibility of termite invasion and damage over the life of the building. Because of their small size (0. ...
Heat is the only other approved method for whole structure treatment for termites in California. [15] Sulfuryl fluoride provides no protection from future infestations, although heavy re-infestation can take several years since drywood termites have slower growing colonies than ground termites.

Workers drape a fumigation tent over Mission San Juan Capistrano in 2005. New research has found that California is the nation's largest emitter of a termite fumigant that is a potent greenhouse gas.

[6] Pathways of exposure to chlordane include ingestion of crops grown in chlordane-contaminated soil, inhalation of air in chlordane-treated homes and from landfills, and ingestion of high-fat foods such as meat ...
