What eats dust mites

How do house dust mites live and feed?

Dust mites thrive best at temperatures between 25 and 30 degrees Celsius and at a relative humidity of 65 to 80 percent.

They need more moisture when the temperature rises in the surrounding area, but they can also survive in fluctuating humidity and temperature values ​​if there is sufficient moisture available for at least a few hours a day (such as in bed). Mites can therefore also exist in a wide area outside of their ideal environmental conditions, even if this means that they are only able to reproduce to a limited extent (Ehrnsberger 1992).

House dust mites live in close association with humans and animals, because they feed on flakes of skin, but also on mold. That is the reason why they feel so comfortable in our surroundings and why they settle in beds in particular. Here there is an abundance of warmth, moisture and food.

If animals live in the house, the living conditions of the house dust mites are even better through the additional supply of moisture and "food" (Ehrnsberger 1992).

Allergologically relevant concentrations of house dust mites can also be found in chicken coops (Franz 2010).

Molds have similar habitat requirements as house dust mites, and they serve them as food. This means that if the living conditions for mold deteriorate, this also harms the mites and vice versa (Brunekreef 1997).

Because they have suction feet, dust mites can hold onto coarse and fiber-rich material. In doing so, they oppose some cleaning procedures (Jung 1996).
