Which of the following is NOT a common species of flea infesting homes?

The answer indicating the Dog Flea is not a common species of flea infesting homes is correct because the term "Dog Flea" commonly refers to a specific flea species known as Ctenocephalides canis. In many regions, the primary fleas encountered in homes are the Cat Flea (Ctenocephalides felis) and sometimes Pulex irritans, which is known as the human flea.

While the Dog Flea does exist, it is less commonly found in domestic environments compared to the Cat Flea, which has adapted to living with both cats and dogs. The concept of Ceratophyllidae pertains to the family of fleas, which includes various species but is more general in nature and does not specifically reference a common household pest.

This distinction underscores the importance of understanding which species are prevalent in residential settings, as it can affect pest control strategies. Recognizing that the Cat Flea and other species like Pulex irritans are more frequently associated with infestations helps pest control technicians effectively address and manage pest problems in homes.
