That's it really. We live in France and have rented our house out. The tenants have just told us that there are moths and the carpets (which are not even 4 years old) are almost threadbare in places.
Is there anything I can advise them to do to get rid of them? Or do we have to remove (and then replace) the carpets? They are fitted all over the first floor (3 bedrooms) and stairs, except for in the bathroom, so we'd rather not do this if we don't have to.
