The news comes after a species alert was released in the Cork area in recent weeks, where a small number of the rodents were spotted.
The creature, native to South America, has already spread rapidly through North American and English countryside’s, destroying local habitats in the process.
It is believed that the animal was first introduced to the country as a novelty attraction to a pet farm in Cork. Though some animals escaped in 2014 and began breeding on the outskirts of Cork city, and then began to spread across the country.
It is described as having similar physical characteristics to an otter except for its rat like tail, and orange/yellow teeth.
They are said to be damaging river banks and over eating vegetation, thus putting pressure on our native species and increasing competition. They also are known to eat bird eggs and any crop vegetables they can find.
They are sexually active at a very young age, three months, and can have up to six or seven pups, meaning they reproduce very quickly.
There are genuine fears that population numbers will increase dramatically, having serious implications on local environments.
The species has been spotted already in Cork, Kilkenny, Tiperary, Offaly and now Leitrim where a species alert is in place.
If anyone spots one in any are they are urged to contact their local council offices.
