The tiger mosquito is not only annoying because it is diurnal and bites aggressively, it is also a possible vector for a variety of pathogens (such as dengue, ZIKA and chikungunya viruses).
In order to detect the spread of these insects and the presence of pathogens in the gels in good time, there have been corresponding monitoring programs in Upper Austria for several years in collaboration with AGES and the University of Veterinary Medicine Vienna. This summer, tiger mosquitoes were repeatedly detected, especially in the central area of Linz. Tiger mosquitoes are imported to Austria via international transport and can become native to us if conditions are favorable.
“In Upper Austria, the risk of becoming infected with an exotic pathogen through the bite of a jellyfish is still classified as very low,” says the Upper Austrian State Medical Directorate.
How you can prevent the spread now in winter
Simple but effective measures can reduce the chances of tiger mosquitoes surviving the winter in Upper Austria.
Tiger mosquito eggs can survive the winter. They stick to the edge of various containers in which water could previously collect (garden furniture, flower pot saucers, bird baths, watering cans, etc.) and they survive even if the respective container dries out.
“In order to prevent the eggs from overwintering and larvae from hatching in the spring, it is therefore particularly important to use all possible Containers should be cleaned thoroughly in the fall. To do this, they should not only be rinsed, but also wiped and, above all, stored in a dry place,” is the recommendation of the experts from the State Health Directorate.
Avoid breeding sites all year round
- Empty small water containers at least once a week (bird baths, flower coasters, paddling pools, toys, etc.).
- Avoid so-called small water points in your garden or on your balcony by removing them, covering them or filling them with sand. Small water points include umbrella stands, fence pipes or decorative elements.
- Avoid other forms of water accumulation: To do this, store objects such as watering cans, tires, empty flower boxes, ashtrays, sand toys, etc. under a roof or turn the objects over so that no water can accumulate in them.
- Close rain barrels tightly or cover them with fine-mesh insect screens.
- Avoid clogged gutters and dripping faucets.
