As always, in order to achieve effective control, it is important to have good bio-ecological knowledge of the target.

Eggs
Eggs are laid either on a moist substrate (Aedes) or on water (Culex, Anopheles).

In the first case, the eggs deposited on flooded soil can remain viable for several weeks, months or even years. They hatch in the first few hours after being submerged, provided that the temperature and photoperiod are favourable. In the second case, hatching usually takes place one to two days after oviposition.

The larvae
All larvae live in water, without exception. The larval stage lasts from one week to several months, depending on the water temperature. The higher the water temperature, the shorter the duration of the larval stage. After passing through four successive stages, they transform into nymphs, which are also aquatic.

Pupae
Unlike the larvae, the nymphs do not feed and are therefore insensitive to ingestion insecticides. Nymphs will emerge after 2 to 5 days: the flying adults.

The adults
Most species are nocturnal (Culex, Anopheles) to crepuscular (Aedes). The males, whose longevity is relatively low, remain close to their hatching site. The females can travel several dozen kilometres with the help of the carrying winds. Aedes are the best flyers and it is not uncommon to find them causing a nuisance sometimes 30 or 40 km from the hatching site. The flight range of Culex does not seem to exceed 2 to 3 km, that of Anopheles is slightly greater.

In order to effectively combat mosquito nuisance, it is therefore necessary to act from the larval stage. This is what you can do with our ready-to-use anti-larvae and anti-mosquito product Penn'Ty Bio.
