Is cedar oil an effective bed bug treatment?

There is no proof that cedar oil is effective in the treatment of bed bugs, according to the Federal Trade Commission. Manufacturers claiming cedar oil (as well as cinnamon) eradicates bed bugs have even received charges for providing misleading advertising.

Cedarcide Industries claimed their cedar oil-based products prevent and treat infestations of bed bugs as well as lice, marketing it to consumers and commercial clients such as hotels and school districts. Cedarcide also ran afoul of the Federal Trade Commission for claiming that the U.S. government was connected with the product and was willing to endorse it, notes the Federal Trade Commission.
