Poultry red mite (PRM) is most important ectoparasite of poultry due to its harmful effects. This study aims to determine the prevalence of PRM in small free range farms and backyards of poultry breeding and to reveal the correlation between the condition and location of hen-houses with the prevalence of PRM. Analyses were carried out between on August 25th – September 30th in a total of 10 districts and 124 villages in Çanakkale, Turkey. The districts and villages visited in the region were divided into 5 different locations based on their geographical structure and analyses were performed for these locations. In total, 355 coops were surveyed, and the presence of red mite and the conditions of poultry houses were recorded. It was found out that the infestation rate of red mite was 72.39% in the province of Çanakkale. According to location prevalence, the highest infestation rate was detected in Location 3 (81.25%) which is situated in the higher parts of the region. The study observed that the presence of perch, location, air conditioning, height and roof materials of the coops significantly affected the infestation rate (P < 0.05). The probability of incidence of mites was higher in the hen-houses higher than 0.60m and with better ventilation and perches. The lowest infestation rate was found in the coops with a galvanized roof, compared to those with the roofs made from tiles, woods or asbestos (P < 0.05). In conclusion, the findings highlighted that geographical and coop conditions should be considered as a point of control for red mites.
