Floodwater mosquitoes / Moustiques d’inondation

There are diverse species of floodwater mosquitoes such as Aedes vexans, Ochlerotatus sticticus and Aedes cinereus. But adaptation to biotopes that are dry most of the time and are only flooded irregularly results in very similar ways of life. Contrary to house mosquitoes, flood mosquitoes lay their eggs individually and normally deposit them on moist ground (A female can produce around 100 eggs per meal of blood). However, the larvae in the developing stage don’t hatch yet. Instead, they can survive in the embryonic membrane for up to three years.

However, the larvae do not always hatch from the eggs, even if they manage to get into water. For example, low temperatures and an excessively high oxygen concentration in the water may prevent them from hatching. Important reasons: When it is cold, the development into a mature adult takes too long, the larvae would not survive in the wrong season and there are often fish and other natural enemies lurking in oxygen-rich waters.

However, when the circumstances are appropriate, for example, when rainfall pushes the ground water upwards and lets nutrient-rich puddles, small ponds and flooded meadows and fields in the spring and summer, larvae can hatch in masses almost simultaneously. If the temperature is right, the development into a mature adult only takes less than a week. In contrast to house mosquitoes, the female flood mosquitoes normally die no later than the onset of winter.

Comment vous protéger des moustiques des zones humides ?

En tant que particulier, vous pouvez aussi vous protéger des moustiques des zones humides. Pour ce faire, vous pouvez équiper la zone concernée de pièges à moustiques (selon la zone, vous aurez éventuellement besoin de plusieurs pièges) : Le piège BG-Mosquitaire CO2  respecte l’environnement car il n’utilise aucun insecticide. Il vous aidera à réduire les nuisances causées par les moustiques. Grâce au BG-Home, spécialement conçu pour les espaces intérieurs, vous pourrez compléter votre système de contrôle.
