A physical barrier that stops mosquito breeding in catch basins
Developed by the University of Copenhagen (patent pending)
Catch basins beneath our streets are hidden breeding sites for the Asian tiger mosquito, which is now establishing itself in European cities. Repeated treatments cannot keep up.
ZikaSeal is a physical barrier that blocks mosquito access without chemicals. Its stainless steel mounting unit is installed once and stays in place for years; the barrier insert in it is inspected and replaced when needed.

Independently tested by EID Méditerranée, Montpellier, report June 2026. The full report is available on Our solution.
The study did not assess whether the device stays watertight over time, or whether it affects the drain’s absorption capacity under heavy rain.
Monaco and Graz.
The two pilot cities of our ESA Kick-Start project, which ran from March to August 2026 and is completed. It developed a satellite-based map of where tiger mosquitoes are likely to breed in a city’s drains, so barriers go where they matter most. ZikaSeal barriers have also been installed in Graz.

A one-time installation with minimal maintenance reduces long-term costs compared with recurring treatments.
