Geckos, these little lizards cling to walls thanks to a tiny layer of sticky fat on their feet

On social networks, many people are calling for help and complaining about gecgkos. Small lizards that clutter the walls and floors of houses that they dirty day after day with their droppings. Most want drastic solutions to eradicate these household invaders. Who are they ?

Gadò kaz, pat cana, ti léza, margouillat, gecko whatever the name given to it, this little animal arouses passions. In Guyana, those who squat our interiors are nocturnal Gekkoninae. They are insectivores who know how to be noticed by the little cries they utter. They are equipped, we explain in the journal Sciences et Avenir, with an ultra-thin layer of fat (it is measured in nanometers) which covers the end of their legs, allowing them an “almost supernatural” grip. It is a recent study that reveals this ability of this mini animal. And this discovery could make it possible to develop research to develop “a vehicle capable of traversing a wall”

The margouillat (Hémidactylus mabouia) is a Gecko which was introduced in Guyana and it is the one with which we live most often.

Taking refuge behind paintings during the day, the gadò kaz, pat cana, ti léza, margouillat, gecko are generally unleashed at night on walls chasing insects, in kitchens in search of food and sometimes even find themselves trapped in the sinks in the dirty dishes.

Harmless, of course, but certainly dirty, their numerous droppings on the white walls and floors in particular poison the existence of all those who aspire to a clean interior and find themselves each morning having to erase the traces of margouillats.
This is why, ultimately, despite all the interest they may represent, they end up in the camp of pests for which repellents are sold in hardware stores.

Nevertheless, the margouillats are part of the Guyanese biodiversity which makes our region attractive and as such, it is perhaps appropriate to accept a certain amount of inconvenience.
