Guernsey has a traditional open air market once per week. Our visitors love it. People dress up in old Guernsey costumes to sell their wares. One of the vendors is a seafood merchant. At this time of year flies can be a problem.
Flies seem to love the seafood more than the UV light hanging high up behind the display.
Other than enclosing the display in a transparent cabinet is there any way of preventing the flies landing on and flying around the seafood. Advice and opinions would be appreciated.
