The standard method is to take a dust sample and to separate the mites from the dust by means of flotation. The results of mite assessment can be improved using methods based on the natural mobility of the mites; the so-called Mobility Test makes use of the intrinsic movement tendencies of the mites, whereas the Heat Escape Method uses the mobility of the mites in connection with the effects of heat. An example concernig two jackets shows the difference in results of mite assessment when using the conventional method (dust sample and flotation) on the one hand, and the new methods (Mobility Test and Heat Escape Method) on the other. It is shown that the conventional method can only supply relative mite numbers. The new methods also enable the user to monitor more efficiently the use of acaricide agents in mite control. This is demonstrated using the example of two beds and a carpet taken from a children's bedroom. The considerably higher numbers of mites suggest that the risk of the occurence of mite allergens and their penetration into the indoor air is even greater than previously assumed.
