The family's apartment is in Vitarnja, on the coastal road between Jelsa and Vrboska, which was sprayed with a cocktail of four potent insecticides on the night of July 12th -13th, and again during the night of August 9th. The family's holiday during early August was marked by 'ferocious' mosquito bites, as pictured on their young son's leg. They are not the first to associate the obvious increase in mosquito activity with the programme of blanket anti-insect spraying ('fogging').

"Dear Eco-Hvar, We had a lovely holiday in Jelsa this year, we have been coming to Jelsa since 2004. This year we were struck by the increase in mosquitoes particularly at night. We were frequently woken up in the middle of the night with buzzing in our ears and in the mornings we would be badly bitten. I attach some photos of the bites! We are wondering if the increase in mosquito activity and their aggression could be linked to pesticide usage?" E-mail 19th August 2017.
