Climate Warming Brings New Ticks and Mosquitoes to Denmark

Danish health researchers issued a warning on July 31, 2026. Warmer weather is pushing new tick and mosquito species north. These insects come from Southern Europe. They can carry new health risks.

• Date of warning: July 31, 2026.
• Main threat: Southern European mosquitoes and ticks migrating north.
• High-risk areas: Municipal parks, nature reserves, and summer cottages.
• Protection steps: Wear long sleeves and pants, and apply insect repellent.
• After outdoors: Check your skin for ticks and call a doctor if ill.

The new species could spread diseases not common in Denmark. Higher summer temperatures make it easier for them to survive. Researchers say climate change is driving this migration.

This change affects daily outdoor life in Copenhagen. Local parks like Amager Fælled see heavy summer use. Many residents also visit summer cottages across Denmark. Insect bites can happen in tall grass and woods.

You should protect yourself during outdoor trips. Wear long clothing in green areas. Use insect repellent on exposed skin. Check your body for ticks after coming home. Contact your local doctor if you feel sick after a bite.
