Arthropod communities of laying hen houses: An integrative pilot study toward conservation biocontrol of the poultry red mite Dermanyssus gallinae

•Multidisciplinary community- and species-level investigation toward a new biocontrol area.•A robust method for exploring mesostigmatid mite communities in manure is provided.•The poultry-farm’s arthropodofauna encompasses interesting predatory species.•Extreme sensitivity to pyrethroid raises the question of unintended effects of treatments.•Effects of region- and local scale factors make conservation biocontrol in poultry farms promising.
