House dust mites can contribute to allergic diseases in dogs just as in humans, and are one of the most common allergens implicated as a trigger in dogs with atopic dermatitis. Indorex® kills these mites and helps  to control them in the home for a full  12 months. However, don’t forget  that the faeces and body fragments  of house dust mites are still thought  to be potent allergens - to both dogs and humans, so regular vacuuming  is essential to effectively reduce their impact.
