Which of the following methods is NOT typically used for bed bug treatment?

Setting traps is not typically used as a method for treating bed bugs. While traps can help monitor bed bug activity or capture individual pests, they are not an effective standalone treatment for eliminating an infestation. Bed bugs are notoriously difficult to eradicate, and effective treatment typically involves methods that directly target their presence and reproductive capacity.

Steam cleaning, thorough crack and crevice treatment, and vacuum cleaning are all validated strategies in managing bed bugs. Steam cleaning uses high temperatures to kill bed bugs and their eggs on contact, making it an effective method for treating infested areas. Thorough crack and crevice treatments often involve applying insecticides in the tiny spaces where bed bugs hide, ensuring that these hidden pests are reached. Vacuuming can remove bed bugs and their eggs from surfaces and is usually an initial step in the treatment process, making it easier for subsequent treatments to be effective.

In summary, traps may serve a purpose in monitoring and understanding the infestation, but they do not contribute sufficiently to the actual elimination process, distinguishing them from the other methods listed.
