Carpet Moths

The carpet moth also known as the clothes moth and webbing clothes moth. The brown / beige adults are around 14-18mm and only have a small wing span. They like to find a dark quiet area to lay their eggs and generally you don’t notice the moths until after the damage has started.

Carpet Moth

A single female can lay around 100-150 eggs which will then can hatch five days later. It is then in this larvae form that they cause the most damage. The small larvae will eat the wool, fibres, pollen, hair and other natural fibres in found your carpet.
