Asian tiger mosquito activity reported in Chicago and Liechtenstein

Authorities in different regions are reporting increased activity or presence of the Asian tiger mosquito. In the Chicago metropolitan area, mosquito abatement districts have noted a significant rise in activity, specifically highlighting the Asian tiger mosquito. Unlike many native species, this mosquito is particularly active during daylight hours. Officials attribute the population surge to hot and humid weather conditions that favor breeding.

In Balzers, Liechtenstein, the first egg of the Asian tiger mosquito was detected in a trap within an industrial area. Local authorities are installing additional traps to determine if a local population is establishing itself. To prevent spread, officials are treating potential breeding sites with Bti (Bacillus thuringiensis israelensis) to target larvae. While the species can transmit tropical diseases, officials note there is currently no danger to people in the area as no such pathogens are circulating in Liechtenstein.
