They target all natural fabrics – cotton, linen, silk, wool.
The larvae (grubs) do the damage and they feed on any bits of sweat, dead skin and food stains, creating holes, so it’s vital that everything is spotlessly clean before it’s put away.

Make sure too that you clean carpets and floors (especially under furniture and along skirting boards.) Empty your vacuum bag or canister straight away
