Luxembourg is low on bites and disease. The tiger mosquito was reported in the capital in 2026.
- No CDC travel notice for mosquito-borne disease
No dengue, chikungunya, West Nile or malaria has been reported, and CDC lists no insect-borne disease for Luxembourg. A day-biting tiger mosquito was reported in Luxembourg City's Bonnevoie district in September 2026, and forest hikes in the Mullerthal call for a tick check.
A few. No mosquito-borne disease has been reported in Luxembourg, CDC lists no insect-borne disease for it, and bites tend to be occasional, on summer evenings by the rivers or on a city terrace. The one change to know about is the day-biting tiger mosquito, which was reported in Luxembourg City in 2026.
The tiger mosquito, reported in the capital
Government notices first reported the tiger mosquito in Luxembourg in 2022, at two sites in Roeser, and reported its eggs in Mamer in July 2023. In September 2026 the Health Directorate reported it in Luxembourg City's Bonnevoie district and said sightings there went back to 2023. On its April 2026 map, the European Centre for Disease Prevention and Control (ECDC) does not list Luxembourg among the countries where the species is established. The same map records a new introduction of Aedes aegypti, another day-biting species, in Luxembourg.
No locally acquired dengue or chikungunya has been reported in Luxembourg. In 2026, ECDC listed local dengue only in Italy and France, and local chikungunya only in France and Italy. Tiger mosquitoes bite by day, with peaks in the morning and late afternoon, so if you're staying in or near Bonnevoie, a coat of repellent before a walk or a terrace lunch covers them.
River evenings and forest trails
Native mosquitoes tend to come out at dusk near the Alzette in Luxembourg City, along the Moselle in Remich, Schengen and Grevenmacher, and by the Sauer. A small spray for a riverside dinner or a wine-village evening is usually enough. Luxembourg does not appear in ECDC's West Nile tables for 2024–2026 or in its season summaries for earlier years.
On the Mullerthal Trail and other woodland hikes, check for ticks. A nationwide survey of 1,394 ticks from 33 sites, published in 2010, found the Lyme disease bacterium in 11.3% of them, with higher rates at more urban sites, and no tick-borne encephalitis virus. ECDC recorded no TBE cases in Luxembourg from 2018 to 2022, and CDC's Luxembourg page lists no TBE vaccine. Wear long trousers, use repellent or permethrin-treated clothing, and check for ticks each evening. Our protection guide has the full routine.
Where you're going
How the main stops compare for a June–September trip.
Luxembourg City: Grund, Pfaffenthal & Kirchberg
No mosquito-borne disease. The tiger mosquito was reported in the Bonnevoie district in 2026, so a small spray for daytime walks and evening terraces covers a city stay.
The Moselle: Remich, Schengen & Grevenmacher
Riverside wine villages with no disease risk. Expect the odd mosquito at a riverside dinner or tasting at dusk.
The Mullerthal & Echternach
Forest and sandstone trails where about one tick in nine carried the Lyme disease bacterium in a 2010 survey. Long trousers, repellent and a tick check each evening.

The Luxembourg kit
- Picaridin 20% travel sprays: odorless for terraces, Moselle evenings and daytime walks around Bonnevoie. The 3.4 oz size rides in a carry-on.
- Permethrin for hiking pants and socks if the Mullerthal Trail is on the plan. Treat them at home before you fly. It goes on clothing, never on skin.
As on any trip, a fever during or after it, including in the weeks after a tick bite, means a doctor visit, and you tell them where you were.
Traveler questions
Are there mosquitoes in Luxembourg?
A few. Bites tend to be occasional, on summer evenings by the Alzette, the Moselle and the Sauer or on a city terrace, and no mosquito-borne disease has been reported in the country. A small spray for evenings out is enough for most trips.
Is the tiger mosquito in Luxembourg City a disease risk?
Not so far. The Health Directorate reported it in the Bonnevoie district in September 2026, and the European Centre for Disease Prevention and Control does not yet list Luxembourg among the countries where it is established. No locally acquired dengue or chikungunya has been reported in Luxembourg. The tiger mosquito bites by day, so if you stay in or near Bonnevoie, put repellent on before a walk or a terrace lunch.
Do I need vaccines or malaria pills for Luxembourg?
No. Luxembourg is on WHO's list of malaria-free countries, and CDC recommends no malaria medicine for it. The yellow fever vaccine is neither recommended nor required. CDC's Luxembourg page lists no tick-borne encephalitis vaccine, and ECDC recorded no TBE cases in Luxembourg from 2018 to 2022.
Are there ticks on the Mullerthal Trail?
Yes. A nationwide survey of 1,394 ticks published in 2010 found the Lyme disease bacterium in 11.3% of them and no TBE virus. Wear long trousers, use repellent or permethrin-treated clothing, and check for ticks each evening after a hike.
