Poultry red mites (PRMs), Dermanyssus gallinae, are one of the most harmful ectoparasites of laying hens. Because of their public health impact, safe, effective methods to eradicate PRMs are greatly needed. Carbon dioxide (CO2 ) was shown to eradicate phytophagous mites; however, there is no evidence that PRMs can be eradicated by CO2. Thus, the efficacy of CO2, applied by direct-spraying and dry ice-generated exposure, for eradicating PRMs was investigated. Both treatments eradicated > 85% of PRMs within 24 h and 100% of PRMs by 120 h of post-treatment. Therefore, these novel approaches may be useful for eradicating PRMs in clinical settings.
