Which exactly from this family (Pelzkäfer, Wollkraut blossom beetle…) remains quite the same, because all are among the material pests in the household.

These larvae eat textiles, wool fabrics, mattresses, upholstery, feathers, carpets, foods and some more – make them unusable for us.

• You should find out where to find more, possibly living: in bed, bed frame, mattress, pillows and blankets
• on and under carpets, also edges and strips
• in the wardrobe, also in the edges, corners and ridges
• on garments, furs and other woolen fabrics
• shelves and shelves for food, also the edges, corners
• Dry food for pets
• dry food, such as cookies, dry meat…

Wash infested textiles at least 60° or freeze for a few days, dispose of infested food outside the house.

Soils suck very well, here also the edges and strips do not forget, because these larvae are masters in hiding.
