Feral Muscovy ducks can breed near urban and suburban lakes and on farms, nesting in tree cavities or on the ground, under shrubs in yards, on apartment balconies, or under roof overhangs.
Some feral populations, such as that in Florida, have a reputation of becoming nuisance pests on occasion.
At night they often sleep at water, if there is a water source available, to flee quickly from predators if awoken.
Small populations of Muscovy ducks can also be found in Ely, Cambridgeshire, Calstock, Cornwall and in Lincoln, Lincolnshire UK.
Muscovy ducks have also been spotted in Walsall Arboretum.
There has been a small population in the Pavilion Gardens public park in Buxton, Derbyshire for many years.

In the US, Muscovy ducks are considered an invasive species.
An owner may raise them for food production only (not for hunting).
Similarly, if the ducks have no owner, 50CFR Part 21 (Migratory Bird Permits ) allows the removal or destruction of the Muscovy ducks, their eggs and nests anywhere in the United States outside of Hidalgo, Starr, and Zapata counties in Texas where they are considered indigenous.
The population in southern Florida is considered, with a population in the several thousands, to be established enough to be considered "countable" for bird watchers.

Legal methods to restrict breeding include not feeding these ducks, deterring them with noise or by chasing.

Although legislation passed in the USA prohibiting trade of Muscovy ducks, Fish and Wildlife Services intend to revise the regulations.
They are not currently implementing them, though release of muscovy ducks to the wild outside their natural
range is prohibited.
