Carpet beetles
How to effectively eliminate the pest
How to recognize carpet beetles? What damage do they cause? And how do you get rid of them? Learn everything about typical signs, hiding places, home remedies, professional control, and the advantages of the Thermo-bug® method here.
What is the carpet beetle?
The carpet beetle (Anthrenus verbasci) belongs to the family of skin beetles and is a widespread pest in households, museums and food processing plants. It is best known for the damage its larvae can cause to textiles, leather, furs and supplies.
Although the adult beetles mainly feed on pollen and are harmless to humans, the larvae are very voracious and can cause considerable material damage. Carpet beetle infestations are often underestimated because the small beetles and larvae often go unnoticed until the damage is visible.
How does the carpet beetle spread?
To effectively control the carpet beetle, it is important to understand how it spreads:
Transport through textiles and furs
Larvae and eggs are often introduced through brought-in second-hand goods.
Flight-capable beetles
Adult beetles can fly and thus easily move from outside into the house or building.
Hidden eggs
Females lay eggs in hard-to-reach places, often in cracks and corners.
Food search
Larvae seek food sources such as animal fibers, so carpets, upholstery and clothing are particularly at risk.
How to recognize a carpet beetle infestation?
Early detection is crucial to avoid long-term damage from carpet beetles. The following signs indicate an infestation:
Found larval skins
Larval skins on carpets, furniture or in cracks indicate an active infestation.
Small holes in textiles
Visible holes in wool clothing, furs or carpets are typical damage.
Small, roundish beetles
Adult carpet beetles are approx. 3 mm in size, brown-black patterned and fly occasionally.
Dusty deposits
Finest residues of larvae can be visible as dust in corners or under furniture.

Get Pests Identified NowWhere does the carpet beetle hide?
The carpet beetle uses various hiding places to protect itself from discovery. Typical hiding places are:
Between carpet fibers and upholstery
Here larvae find protection and food.
In wardrobes and under garments
Especially where animal fibers are stored.
In cracks and joints of furniture
Small crevices offer retreat possibilities.
Behind baseboards and pictures
Hidden areas that are rarely cleaned.
In storage rooms, especially with animal products
Larvae also feed on animal foods.
What effects does a carpet beetle infestation have?
The damage caused by carpet beetles is primarily of a material nature, but can also have health aspects:
Damage to textiles
Clothing made of wool, silk, leather and fur is eaten by the larvae.
Destruction of upholstered furniture and carpets
Fibers and upholstery materials are destroyed.
Contamination of supplies
Food can be contaminated by beetles and larvae.
Allergic reactions
Larval hairs can trigger skin irritation or respiratory allergies in sensitive individuals.
How to prevent a carpet beetle infestation?
Preventive measures are essential to keep carpet beetles away or prevent re-settlement:
Regular vacuuming
Thoroughly clean carpets, upholstery and hard-to-reach areas in particular.
Protect textiles
Store sensitive clothing airtight and dark.
Ventilate rooms well and keep them dry
Moisture promotes pests and their development.
Use of lavender, cedar wood
or other natural repellents.
Beetle traps with pheromones
for monitoring and early detection.
Is a carpet beetle infestation notifiable?
A carpet beetle infestation is generally not notifiable, especially in private apartments and houses. But: Tenants are obliged to inform their landlord about an infestation so that control measures can be initiated.
However, exceptions apply to food processing plants, where an infestation must be reported immediately in accordance with the Infection Protection Act. In these establishments, it is mandatory to immediately commission a specialist company to control the infestation and provide proof of the measures taken in order to avoid health risks.
How to control carpet beetles?
Control depends on the extent of the infestation. Minor infestations can often be treated with home remedies, while severe or deep-seated infestations require professional methods.
Home remedies
Vinegar water
Wiping infested surfaces to remove eggs and larvae.
Exposure to cold or heat
Freeze clothing and small textiles in the freezer or wash at at least 60 °C.
Natural fragrances
Use of lavender, cedar wood or clove oil as a repellent.
Professional control
Insecticide treatments
Special preparations for the targeted control of larvae and beetles.
Laying out pheromone traps
for monitoring and reduction of the population.
