Every animal, even the most annoying one, has a fundamental role in the balance of nature. When it comes to the food chain, mosquitoes are the perfect prey for different animals: amphibians, fish, insectivorous birds, dragonflies, bats, lizards, geckos, ants, spiders ...

Themosquitoesthey are able to thrive very well in domestic areas due to the absence of natural predators. How many of you have geckos, amphibians and lizards in the garden ?!

Biological fight against mosquitoes, the natural predators

  • Gambusia and Tench (fish)

Of the 40 species of gambusia, the most ravenous in the biological fight against mosquitoes are the Gambusia affinis and Gambusia holbrooki which feed on mosquito eggs and larvae. It is not wise to introduce the Gambusia in artificial lakes with amphibians and other beneficial insects ... The Gambusia, in fact, also feeds on the larvae and eggs of useful insects or even amphibians.

The Tench has also been adopted in Italy for the biological fight against mosquitoes, just think that an adult individual can eat 1500 mosquito larvae every day! This precious fish was used by the Versilia-Massaciuccoli Reclamation Consortium, releasing about 10,000 specimens of tench in the consortium canals.

Other fish "mosquito-killer "is Fundulus diaphanus, in the USA it is widely used inbiological fight against mosquitoes but in local waters it is better to use tench tench.

  • Dragonflies and bridesmaids

Another 100% environmentally friendly remedy to reduce the proliferation of mosquitoes is to adopt dragonflies and bridesmaids. The bridesmaids are less known, we can describe them as the cousins ​​of dragonflies (they look alike and belong to the same order Odonata), their scientific name iszygopetaand like dragonflies, they have an elongated and thin body, large eyes and wings which, during the resting phase, are placed on the back.

  • Bats

Bats are too often mistreated, yet they are cute! They are our little flying friends and in thebiological fight against mosquitoesthey can play a crucial role. Bats feed on insects only, so they are a godsend for farmers and gardeners. Avoid the use of any pesticide and to adopt a colony, arrange small wooden lodgings like this Bat Box.

  • Entomophthora culicis

A 1981 study found that mushroomsEntomophthora culicisthey are toxic to several species of mosquitoes. The spores of these fungi function as a natural pesticide: they weaken the vital functions of the mosquito and impair its ability to fly.

  • Elephant mosquito - Toxorhynchites

Can you fight fire, with fire? Sure! Mosquitoes of the genus Toxorhynchites are among the largest mosquito specimens in the world. Fortunately, they do not feed on blood but on vegetable nectar! The elephant mosquito, in the larval stage, is a formidable predator because it feeds on the larvae of other insects, including mosquitoes.

Mosquito traps

If the biological fight against mosquitoes it seems too difficult to put in place, you can count on traps and other harmless tools for the environment that can eliminate mosquitoes.

First of all, let's say right away that mosquitoes can deposit in saucers, in manholes and in any place where a minimum water stagnation is created. If you have a garden, avoid water stagnation for several days.

Aqualab mosquito larvae trap
The aforementioned trapping device induces mosquitoes to lay eggs and hatch the larvae these will be trapped. After a few days of activity, the device will host all forms of the mosquito's life cycle (eggs, larvae, pupae and adults) creating awareness of how a few liters of water can give rise to such a large number of mosquitoes. Very effective for eliminate mosquitoes in the garden.
