Tiger mosquitoes can transmit tropical diseases such as dengue fever, with symptoms such as fever, chills, headache, and pain behind the eyes. Tiger mosquitoes that are not infected with viruses also cause a lot of inconvenience. This species bites during the day, so mosquito nets provide no protection.

Tiger mosquitoes recently appeared in a shopping complex in Weert, and the Dutch Consumer Products and Food Safety Authority will start a major control campaign this week. In such a procedure, mosquito fighters go from door to door, looking for places with standing water; Mosquitoes can already breed in a layer of water in a roof gutter or in a fallen soft drink bottle cap. If the water cannot be removed, treatment with granules kills the larvae. Mosquito traps with attractants and sewer inspections should provide more information about mosquito infestations.

If the mosquito then breeds, it will be a while before the nuisance starts and people sound the alarm. And then there are often hundreds of mosquitoes already.

A warming climate also works in favor of the mosquito, which feels more comfortable in warmer temperatures. Koenraadt: “We are at a critical stage, because the Netherlands is getting warmer in winter so that mosquitoes can survive. And if a mosquito bites an infected person, the evolution of the virus in the mosquito’s body also accelerates at higher temperatures.”
