Rodent mite bites leave multiple groups or individual small itchy papules (around 1–2 mm in diameter)[7] on the skin (papular urticaria).[9][10] These are found mostly "on the upper extremities, neck, upper trunk and face".[7]
Diagnosis
Diagnosis requires species identification of the parasite, which will be likely to be found in the environment of its host rather than on the host's skin.[10] Rodent mites are very small, for O. bacoti "female mites reach a size between 0.75 and 1.40 mm, males are a little smaller".[7]
Treatment
The original rodent host of the mites must be located and eradicated,[11] and their nests removed.[12] Steps should also be taken to prevent future infestations, such as by blocking the rodents means of entry into the building. The patient's environment should then be treated,[10] using both non-residual and residual insecticides, mites crawling in the open can be removed by vacuuming or with a cloth moistened with alcohol.[12]
