People see the adults on a windowsill in spring, assume a harmless beetle wandered in, and never connect them to the bare patch under the sofa.
In a house with mature trees around it, this is where the source usually is — and it decides whether the treatment lasts.
If you are finding beetles in several upstairs rooms, look up before you count rooms.
Treating four bedrooms while a bird's nest in the eaves keeps producing beetles is a treatment with an expiry date of about eleven months.

View Carpet Beetle Control Stanmore →Larvae moult repeatedly and leave the empty bristly skins behind. Those skins look almost exactly like larvae, which is why people report far more than are present — and why some conclude a treatment has failed.
A live larva moves when disturbed. A shed skin is papery and hollow.
Some people react to carpet beetle larval hairs with an itchy rash that gets mistaken for bites.

Moth larvae are smooth and cream with silk webbing. Beetle larvae are brown, bristly, and leave shed skins.

They mean more nesting birds using the eaves, and an old nest is a self-sustaining source producing adults into the rooms below.
Check the timing — some wild birds and their active nests are legally protected. Wear gloves and a mask, and if you find bat droppings, stop and take specialist advice.
Larvae moult repeatedly and leave empty bristly skins that look very like the larvae themselves.
No. Some people react to the larval hairs with an itchy rash mistaken for bites.
