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.

Where 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.

Frequently Asked Questions (FAQs)

Are car­pet beet­les dan­ge­rous for humans?

Yes, typi­cal holes and small beet­les are first indi­ca­ti­ons.
