[8] Rodent mite bites leave multiple groups or individual small itchy papules (around 1–2 mm in diameter)[7] on the skin (papular urticaria).
[7] 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] Bites can be treated with antihistamines and corticosteroids, to relieve the associated itching and allergic reactions.
