How to Get Rid of Nutria Rats

Save

Nutria rats are rodents that are originally native to South America; they have been trans-located to North America by various individuals, as well as state and federal agencies. Nutria rats mainly cause damage by burrowing and feeding. Their burrows serve to weaken flood control and water-retaining levees to the degree that they have to undergo reconstruction. They also damage various crops, gardens and grasses via their feeding habits. For the individual who finds nutria rats to be a nuisance, control and removal methods are available.

Things You'll Need

  • Leg hold trap
  • Bait (chunks of carrots or sweet potatoes)
  • Live trap

Leghold Trapping

Obtain a leghold trap from a supplier such as a double longspring trap, number 11 or 2, for trapping the nutria.

Set the trap in an area where you notice nutria trails, droppings or where nutria activity has been observed. Place the trap just off the center of the trail so it will catch the nutria's foot, or place the trap right under the surface of the water to which the trail leads. Stake the traps to the ground, or to a stationary object nearby.

Place bait such as chunks of carrots or sweet potatoes beside the leghold traps, if desired. Don't place the bait inside because the nutria pick up food with their teeth.

Dispose of any trapped nutria in a humane manner.

Live trapping

Obtain a single or double door live trap that is 9-by-9-by-32 inches, or larger, in size.

Place the trap in an area where there is known nutria activity. You can determine this from footprints, tail prints and droppings.

Place chunks of sweet potatoes and carrots directly outside of the cage door, leading into it.

Set the live trap according to the manufacturer's instruction.

Humanely dispose of any nutria that you catch in the live trap.

Tips & Warnings
