Mammal✓ Protected species
Weasel / Stone Marten / Polecat
Mustela nivalis
What to do NOW
- 1Wear thick gloves — mustelids bite hard and do not let go
- 2Cover with a towel and pick up with resistant gloves
- 3Place in a sturdy dark box (mustelids are excellent escapers — seal it well)
- 4Keep in a cool, quiet place
- 5Contact a CRAS specialised in small mammals
NEVER do this
- Do not pick up without resistant gloves — bites are deep
- Do not use soft plastic containers — they will chew through them
- Do not approach a weasel with young — she defends the nest aggressively
Important note
Weasel, stone marten and polecat are the most common mustelids in Italy. The stone marten (Martes foina) is frequent in urban and peri-urban environments, often found injured after road accidents. The weasel is the smallest (15-25 cm). Note: the polecat (Mustela putorius) has anal glands that secrete a very foul-smelling liquid when stressed.
Legal protection
Weasel, stoat and polecat are protected by Law 157/1992.
