The City of Toulouse is experimenting with a new rat control method for the banks of the Garonne and its canals: the release of ferrets. They scare off rodents and limit the use of chemicals.
Ferrets to ratify the banks of the Garonne and its canals? This is the method that the City of Toulouse has been experimenting since the end of September. “It is an ancestral technique, little expressed”, emphasizes Françoise Ampoulange, municipal councilor responsible for animals in the city.
Indeed, this technique consists in freeing a ferret in a rat burrow. It then infiltrates the galleries and scares away the breeding pairs of the colony, hidden at the back. Upon release, the latter are detained and euthanized. Known to scare off rodents just by their scent, ferrets leave a fairly strong scent imprint in tunnels after their passage. As a result, the nests emit more time before being again colonized.
A less harmful method than rat poison products
“Ferret rat control” is found to be much less harmful to the environment than the rat poison method is usually used. As with preventative baiting with rat poison. Moreover, these methods also have the drawback of harming non-target species. In addition, rodent control by ferret makes it possible to avoid the use of biocides and thus to protect soils which are no longer polluted by substances harmful to the environment.
