NVWA carries out follow-up treatment to combat Asian tiger mosquito
The Dutch Food and Consumer Product Safety Authority (NVWA) will once again carry out control measures this spring to combat the Asian tiger mosquito in our municipality. Last year, tiger mosquitoes were found within a 500-metre radius of several addresses. Since the eggs of this mosquito can survive the winter, the mosquito may still be present. The NVWA states: “Because the eggs of the mosquito can survive the winter, it is possible that the tiger mosquito is still present.”
With these measures, the NVWA aims to prevent further spread of the mosquito. The Asian tiger mosquito can transmit tropical diseases if it becomes established in larger numbers.
What will the NVWA do?
In April and May, the NVWA will carry out two follow-up treatments in the area where tiger mosquitoes were previously found. If mosquitoes are found again, additional actions will follow, including:
- – removing standing water where mosquitoes gather;
- – treating water that cannot be removed with a product that kills mosquito larvae (safe for humans and animals);
- – placing mosquito traps to monitor whether the control measures are effective;
- – treating street drains with a larvicide.
What does this mean for you as a resident?
NVWA or B2 Pest Control staff may visit your home to inspect your garden. They can always provide identification upon request.
How do you recognise the Asian tiger mosquito?
Residents in the affected area will receive a letter and poster with information on identifying the tiger mosquito. The mosquito is small, black with white stripes, and bites mainly during the day.
What can you do yourself?
You can help by preventing breeding sites. The tiger mosquito lays eggs in small amounts of standing water. Pay attention to:
- – empty buckets, watering cans, and plant pots;
- – uncovered rain barrels;
- – toys or waste where water can collect;
- – gutters or drains that do not drain properly.
The NVWA emphasises that any material where a thin layer of water can remain may serve as a breeding site. Extra attention to clearing street litter also helps prevent spread.
Have you found an Asian tiger mosquito?
Keep the mosquito and report it via the NVWA. They would appreciate receiving a photo of the mosquito found.
