Spesies of house dust mite which has been proven to be related with the incidence of allergies are Dermatophagoides pteronyssinus and Dermatophagoides farinae. The purpose of this study is to describe the density of house dust mites species in residence houses in Kelurahan Jati. The study was a descriptive study with 96 samples taken from two habitats, namely beds and carpets in 48 homes that have been selected randomly. House dust mites were identified using a light microscope with magnification of 40 times. The results showed that 56 of 96 samples were positive of house dust mites. This study showed that Dermatophagoides pteronyssinus was the most commonly found spesies of house dust mite (71 mites) with the highest density in the bed (6.88 mites/ gram of dust). Species Dermatophagoides farinae only found as many as 5 mites with the highest density in the carpet (0.46 mites/ gram of dust).
