Objective To investigate the cause of dermatitis cases in a urban area of Beijing in 2016. Methods Specimen identification, field investigation and literature retrieval were performed to find the cause of dermatitis so that the proposal for the patients was put forward. Results The typical symptoms included skin red papules and itch. Some small red bugs were collected from the bed by the patients and the specimens were identified as chicken mite Dermanyssus gallinae. The mites disappeared after the patients sprayed pyrethroid insecticide aerosol in their apartment. We checked the apartment and found no rodent infestation and pet activities. Instead, sparrows and pigeons were seen on the windowsill frequently. There have been six dermatitis case reports infested by D. gallinae in China so far. All mites in the case reports were introduced by chickens or sparrows. Conclusion Based on the investigation results, we speculated that the birds on the windowsill carried the chicken mites into the patient's apartment which caused the dermatitis.
