The islands in the Cyclades and Dodecanese groups are most quite dry, in fact even arid. Islands like Santorini do not have a natural water source – no river, lake, or dam, so mosquitoes are quite uncommon.
Generally speaking, there are mosquitos in Greece. The good thing is that they aren't everywhere. Expect to get bitten more times if you are next to a river, a stream or a swamp... They tend to be present at places with water.
He explains that in the temperate zone, where Greece belongs, active transmission is mainly in July, August and September. This is the epizootic phase, during which infected mosquitoes that have picked up the pathogen from birds will bite humans.
These insects are most active during the late spring, summer, and early fall months. They particularly like to be active during the evening hours and when it is humid outside. Mosquitoes can bite at any time of the day, but you and your family are at higher risk during these times.
“It's not that they don't contain mosquito repellents,” says Immo Hansen, PhD, a co-author of the study and professor of biology at New Mexico State University. But “wearing a bracelet to protect your whole body from mosquitoes,” he says, is just not enough protection.
