Tiger mosquitoes expected to remain active through autumn

Tiger mosquitoes (Aedes albopictus) are expected to remain highly active through autumn due to favorable weather conditions. While extreme summer heat and drought previously limited their development, recent rainfall has replenished stagnant water sources such as gutters, flowerpot saucers, and water collection containers, providing essential breeding sites.

When these rains are accompanied by mild temperatures—typically above 15-18°C—larvae hatch rapidly, leading to a secondary peak in mosquito activity. The tiger mosquito is a diurnal predator that can remain active until temperatures consistently drop below 12°C. Furthermore, their eggs are highly resilient and can survive for several months in dry or cold conditions before hatching when moisture becomes available.

To mitigate the risk of bites, experts recommend regularly emptying any small reservoirs of stagnant water around residential areas.
