What to do if carpet beetles are found on the bed?

Finding carpet beetle larvae on the bed is unpleasant, but following these steps will eliminate them.

Step 1: Remove and wash bedding

Remove all sheets, duvet covers, and pillowcases:

• Wash in water above 60°C (high heat kills larvae and eggs).
• If hot water is unavailable, tumble dry on high heat for more than 30 minutes.
• Do not shake bedding before washing, to prevent eggs and hairs from scattering.

Step 2: Vacuum the mattress

Use a vacuum cleaner (preferably with HEPA filter) to thoroughly vacuum the mattress:

• Vacuum both sides.
• Focus on seams and edge crevices.
• If there are stains or food residue marks on the mattress, wipe clean with a damp cloth before vacuuming.

Step 3: Check under the bed and bed frame

• Check for food debris and pet hair accumulation under the bed.
• Spray dinotefuran-containing household insecticide in bed frame crevices and behind the headboard.
• Once dry, the film kills larvae that crawl over it.

Step 4: Trace the source

Carpet beetle larvae do not appear on the bed for no reason:

• Check wardrobes for sources (fur/wool items may be infested).
• Check where pets sleep.
• Check nearby carpets for infestation.

Step 5: Maintain prevention

Keep the bedroom clean and dry; do not eat snacks or store food in the bedroom. Vacuum regularly, especially carpets, under beds, and corners.
