Currently residing in SW France Recently have had to replace 4 light fittings in upstairs rooms which appear to have been chewed through! After only 1 month-same has happened to landing light. String of dragon fly lights on tree in garden has suffered same fate! Am baffled-attic recently renovated( ie 6yrs ago), into rooms therefore very little roof space left. No noises or smells whilst I've been here for last 8 weeks. Any ideas anyone please??
