Asian Tiger Mosquito Outbreaks Trigger Control Measures in Belgium and Netherlands

Public health authorities in Belgium have launched targeted inspections and treatments for the Asian tiger mosquito in Melle, according to municipal reports and public health documentation from September 2026. The small, black-and-white insect bites during the daytime and can transmit viruses in rare cases, though officials emphasize that the current risk of local virus transmission remains extremely low.

The coordinated response involves the Instituut voor Tropische Geneeskunde Antwerpen, Sciensano, the local administration of Merelbeke-Melle, and the pest control firm Anticimex, according to municipal information released for September 2026. Teams are conducting house-to-house inspections across several designated streets to locate and manage standing water sources where the insects lay their eggs.

Targeted Streets and Inspection Schedule in Melle

From Tuesday, September 22, 2026, to Monday, September 28, 2026, Anticimex personnel are visiting specific neighborhoods to check gardens and outdoor spaces. The treatment round covers the Brugstraat in its entirety, the Veerweg in its entirety, and specific stretches of the Kloosterstraat, Brusselsesteenweg, and Geraardsbergsesteenweg, alongside properties on Eikerwegel, according to local administrative notices.

Workers knock on residents’ doors to request access to yards, balconies, and patios. They inspect potential breeding sites such as plant pots, saucers, buckets, rain barrels, drinking bowls, parasol bases, and drain pits. Where necessary, staff remove or treat these containers free of charge, according to municipal guidelines.

Identification and Public Health Risk Context

The Asian tiger mosquito is recognized by white stripes on its legs, white tips on its hind legs, and a distinct white stripe running down the back of the head and thorax, as detailed by Sciensano and local authorities. While the insect can occasionally transmit viruses like dengue, chikungunya, and zika, authorities state that the likelihood of virus transmission in Belgium is currently very small.

Officials stress that there is no cause for panic, and residents do not need to stay indoors or alter their daily routines. The primary goal of the intervention is to prevent the establishment and further spread of the species in the region.

Practical Prevention Measures for Residents

Public health guidance encourages property owners to eliminate standing water, which serves as a breeding ground for the insects. Recommended actions include regularly emptying small containers, covering rain barrels tightly with a lid or fine mesh, and refreshing animal drinking water every five days.

Residents who suspect they have spotted a tiger mosquito are asked to photograph the insect and submit a report through the muggensurveillance.be website or its dedicated mobile application, where identification guides are also available.
