Warmer Winters Lead to Year-Round Mosquito Activity
The Aedes aegypti mosquito, which first appeared in Madeira in 2005, has expanded its range over the years. While the mosquito traditionally thrives in warmer, low-altitude areas near the sea, recent years have seen it move into higher-altitude regions, where it was previously rare or absent. Experts attribute this change to milder winters, which allow the species to remain active throughout the year.
Traps and Public Awareness Campaigns in Place
To monitor and control the spread, local authorities have set up 26 traps across the city. At the same time, they have launched awareness campaigns targeting both businesses and residents. Over 1,700 commercial establishments have been visited, with officials sharing practical advice on reducing mosquito breeding grounds. Restaurants, in particular, have been urged to address water buildup in equipment like refrigerator trays, which can serve as mosquito habitats.
Simple Measures Can Help Control Mosquito Breeding
Residents are also being educated on steps to prevent mosquito proliferation at home. Leaflets distributed to households explain how standing water in drains, such as those in bathrooms or balconies, can attract mosquitoes. Authorities recommend sprinkling salt into these drains as an easy and effective measure to prevent mosquito breeding.
Higher Regions See Increasing Mosquito Presence
The arrival of Aedes aegypti in Madeira’s higher-altitude areas is a new challenge for public health efforts. While lower-altitude regions remain the most affected due to their warmer temperatures, the past three years have shown a gradual increase in mosquito activity in cooler, higher locations. Local officials continue to adapt their strategies to tackle this growing concern.
