Why is the Nutria rat considered a pest?

  • They destroy trees by girdling them
  • They eat farmers vegetable crops, garden plants, and dig up your grass looking for food
  • They eat vital wetland marsh vegetation until it is gone
  • They dig holes and burrow everywhere and anywhere making it unsafe to walk for both you and your livestock
  • They dig and nest in levees, water control dikes, thus causing them to fail suddenly
  • And the list goes on and on.

So what does one do to control nutria?



  • Taste: Apply a repellent that when applied to a plant or tree tastes bad to nutria, they will stop eating it.
  • Touch: Apply a repellent that will not dry and actually sticks to them and they will go elsewhere.
  • Sound: Sudden sounds activated by their motion work well. Nutria disappear when you move toward them and these sound devices cause the same type of quick response to unusual or sudden sound.
  • Motion: Motion activated water sprayers do a great job in encouraging them to go elsewhere.
  • Fertility control: As far as we know, the use of this method is still experimental and not available to us common folk.
  • Cold: They don’t like it and will go to a warmer place. But we haven’t learned how anyone has used this to prevent them yet. Make your million by figuring out a way to use the cold to drive them back to South America.


  • Allowing animals including alligators, eagles, turtles, to live in the same area can cut the coypu population.

Live Trapping: Bait with cracked corn or a chemical lure that emits an odor that is a sexual attractant and they will walk right into a live trap easily.

  • Snares: Destroy it after catching.
  • Leg hold: Destroy it after catching.
  • Live cage traps: Place the cage traps on land or on a raft floating in the water. Destroy them by drowning or shooting them while they are in the trap or relocate them far far far far far away.

Kill Trapping: Bait with cracked corn.

  • Body grip traps: These traps kill quickly.

Shooting: Dispatch them safely and legally as applicable in your area.

Pesticides: There are no approved pesticides for these pests.


Poison: There are no approved poisons that kill them.
