Is there likely to be a problem with mosquitoes or wasps in August? We often visit the greek isands at this time of year but each place and visit has been different.
A couple of years ago in Corfu the wasps really were intrusive, they would hover around almost every meal we had, despite the waiters bringing out burning coffee to deter them. My sister was stung as she accidentally put her hand down on one. On a different holiday, my son had a bad reaction to a mosquito bite in Corfu and all of his mates were bitten despite using anti mosie products.
I will be taking our usual plug-in and mosie spray but just wondered how bad the mosie situation is in this part of Crete in August- and although I can live with spotting the occasional wasp, I'm hoping they won't be out in force as they were in Corfu the last time we were there.
