Step 1: Check the Stored Wool First

In a flat this is more often the source than the carpet, and it is the easiest thing to check.

• Empty every wardrobe of wool, cashmere and silk and inspect each item
• Look for several small separate holes — the typical beetle pattern on clothing
• Check the wardrobe base, seams and corners for larvae and shed skins
• Check suitcases, under-bed boxes and anything in built-in storage
• Check an airing cupboard for stored blankets and woollens

Items stored unworn since last winter are the classic. Soiled wool — sweat, food residue, body oils — is considerably more attractive than clean.

Step 2: Check Above You

The other common source, and the one people never check.

Carpet beetles feed naturally on keratin from feathers and animal remains. An old bird's nest in a roof void, a nest in a disused chimney, or pigeon roosting on a ledge or flat roof is a self-sustaining source producing adults into the property below.

• If you are top-floor, ask about the roof void
• Check any disused chimney breast
• Look at ledges, balconies and window reveals for pigeon roosting
• In a house, go into the loft and check the eaves
• Tell us or the managing agent what you find — it changes what needs doing

Step 3: Find the Larvae in the Carpet

• Under furniture that has not moved in a year
• Along carpet edges and beneath the gripper at skirtings
• Under rugs, and inside rolled or stored ones
• In the corners behind permanently open doors
• Under built-in storage where you can reach

You are looking for brown bristly larvae, shed skins that look like more larvae, and irregular holes or thinning.

Step 4: Vacuum Properly

• Crevice tool along every skirting, slowly
• Under furniture rather than around it
• Both sides of every rug, and the floor beneath
• Inside wardrobe bases and along seams
• Repeat every few days for several weeks
• Empty into a sealed bag and put it outside

Step 5: Deal With the Textiles

• Hot wash anything washable
• Freeze smaller items that cannot be washed — sealed bag, domestic freezer, a couple of weeks
• Dry clean valuable items that take neither
• Store clean and in sealed containers rather than open wardrobes

What Does Not Work

• Killing the adults on the windowsill. They are not doing the damage and are on their way out
• Mothballs and cedar. Unreliable against an established infestation
• Supermarket sprays alone. Surface treatment; larvae are at the pile base and in the wardrobe
• Shampooing the carpet. Cleans it, does not remove larvae
• Treating rooms while ignoring stored wool or a roof source. The expensive mistake
• Pheromone traps. Less useful than for moths — monitoring at best

Professional Treatment

Treatment reaches the base of the pile, carpet edges and under-furniture areas where larvae actually are, and stays active as further eggs hatch. Tell us if you have found or suspect a source above.

Afterwards

• Keep vacuuming edges and under furniture
• Move furniture periodically instead of leaving it static
• Store wool clean and sealed
• Watch windowsills in spring — adults reappearing is your early warning
• If a nest was removed, make sure the access point was closed

Is It Beetles or Moths?

Beetle larvae are brown and bristly with shed skins; moth larvae smooth and cream with silk webbing. A photograph settles it.

Questions People Ask

Do they bite?

No. Some people react to the larval hairs with an itchy rash, which is different.

Will they eat synthetic carpet?

No. They need keratin from natural animal fibres.

Should I tell my landlord?

If you rent, yes — in writing with photographs. Carpet damage is a common deposit dispute, and a roof-void source is the freeholder's or landlord's to deal with.
