Sweet wormwood (Artemisia annua): Extracts such as leaf juice serve as natural mosquito repellents.
Mosquitoes shy away from sweet wormwood; break off a leaf from the plant and rub on skin for immediate effectiveness.

Native to northeastern Queensland in the Land Down Under, lemon eucalyptus trees (Corymbia citriodora), also known as lemon-scented gum, waft an aroma repugnant to mosquitoes.
An extract from the tree's leaves and twigs serves as an effective repellent and a natural alternative to chemical products such as DEET.

DEET (N,N-diethyl-meta-toluamide), developed by U.S. Army in 1946, is an effective chemical repellent that blocks insects' olfactory receptors and also exudes an odor that mosquitoes dislike.
Health issues such as insomnia, mood swings, seizures, and skin irritations may be experienced via products with concentrations of DEET well in excess of 30 percent.
DEET-based products include Cutter Skinsations, DEET Plus, Off! and Ultrathon; Image no. K7243-10: Photo by Scott Bauer, Public Domain, via USDA Agricultural Research Service (ARS) @ https://www.ars.usda.gov/oc/images/photos/k7243-10/

Mira, I hope that a Wizzley article will follow from whenever you visit the Danube Delta!
No, I don't know what they're using. The Danube Delta is a reservation of biosphere, so I imagine they're careful with what they're using. I do think though that people still carry mosquito sprays when they go. I haven't been there since I was a kid. I do plan to go in the near future though.
Mira, It's probably some form of cosmic justice that so many pests can be discouraged or eliminated by what they apparently perceive as unappealing colors and unpleasant scents! Do you know what has been used if the Danube Delta is having less or no mosquito problems?
So mosquitoes have favorite colors? Never thought about it. And it's too bad that the range is so big. So lemon eucalyptus oil works to repel mosquitoes. Good to know. We have the Danube Delta over here and mosquitoes there are (or used to be) a big problem.
