But whether the one or another (as well as the carpet beetle) from this family remains quite the same, because all are among the material pests in the household.

Their larvae feed on textiles, wool fabrics, mattresses, upholstery, feathers, carpets and some more – making them unusable for us.

There are already several one should look for where more beetles and especially larvae can be found:

Targeted here

• 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
• 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.
