We spent a week around Ft William area last week which included 4 munro days & a 20 mile cycle day along the GGW.
Used to use Skin So Soft but it's never worked, so on recommendation, we used Sainsburys extra strength insect repellent (which is 50% deet).
Between my wife & myself, we only suffered 4 clegg bites & 5 midge bites.
Know what I'll be using from now.
