Combat Tropical Disease Carriers: Wisdom on Dealing with Asian Tiger Mosquitoes
Control mosquito infestations more efficiently with tablet treatments - Simplifying Tablet Usability
Want to tackle the Asian Tiger Mosquito issue in a breeze? Baden-Württemberg is pushing for a simplified distribution of Bti tablets to counteract these disease-spreading creatures. Previously, tablets distribution was limited to knowledgeable individuals, making the process more complicated. The new plan aims to change the federal law to ease distribution.
What gives the Asian Tiger Mosquito (Aedes albopictus) its ominous reputation? They're tiny yet potent, with sizes ranging between two and ten millimeters, and sporting a striking black-and-white pattern. The Asian Tiger Mosquito jeopardizes public health by carrying disease-causing agents like the Chikungunya virus, Dengue virus, Zika virus, and others.
While a local mosquito can only transmit tropical diseases when it bites an infected traveler and absorbs viruses through the blood, high temperatures allow viruses to multiply inside the mosquito and then get transmitted to other people with another bite. Experts agree: fewer Tiger Mosquitoes minimize the risk of local transmissions of tropical infectious diseases.
Since the initial populations were discovered in Freiburg im Breisgau and Heidelberg in 2015, the Tiger Mosquito has been spreading across the warmer regions of Baden-Württemberg, including along the Upper Rhine, the Rhine-Neckar region, and the middle Neckar. Recents sightings near Lake Constance have also been reported. Some municipalities, like Kehl, have resigned themselves to the thought of managing ongoing Tiger Mosquito populations.
Despite the widespread presence of these mosquitoes, no locally transmitted infections like Dengue or Chikungunya have been reported in Germany. Yet, cases in nearby countries such as France, Spain, Italy, and Croatia serve as a stark reminder of the potential risks. Here, "locally acquired" means that individuals contracted the diseases within these countries.
How exactly do Bti tablets work? Containing protein crystals from the naturally occurring bacterium Bacillus thuringiensis israelensis, these crystals are toxic to the larvae of biting mosquitoes and midges in low doses. The tablets target only the larvae’s gut, causing them to die due to the destruction of gut tissue. To put users' minds at ease, Bti tablets are not harmful to humans, pets, birds, or other animals.
Luckily, Bti tablets have been available for municipality use for some time. However, new EU guidelines (in effect from 2025) require personal consultations with knowledgeable staff before distribution, making it more difficult for individuals to combat the unwanted mosquitoes. Baden-Württemberg's initiative aims to change these guidelines.
So, where should you apply Bti tablets, and how often? These tablets can help combat Tiger Mosquitoes when other methods—such as disposal, renovation, or sealing—prove ineffective. For instance, rain barrels that cannot be properly sealed can be treated with Bti tablets every 14 days according to the instructions. Similarly, cisterns, manholes, or drains where water stands for extended periods may benefit from Bti tablet treatment. Given their biodegradable nature, Bti tablets require reapplication approximately every 14 days.
What sets Asian Tiger Mosquitoes apart from native species? Distinctive during the day, this mosquito has a strong bite and specifically prefers small water accumulations as breeding sites. Unlike many native biting mosquito species, the Asian tiger mosquito uses water collection sites like tree hollows with ground-level water accumulations, as well as water residues in flower vases, buckets, rain barrels, and puddles on tarps or in old tires.
The Nature and Biodiversity Conservation Union highlights the prevalence of consultation sessions as crucial, particularly to avoid misuse or incorrect use of Bti. Biting mosquitoes serve valuable roles in ecosystems, aiding fish, amphibians, bats, and birds. The approval of Bti is based on risk assessment, rather than harmlessness. European regulations place strict limitations on the use and sale of Bti products.
