The city's food scene, old buildings and mild winters make New Orleans a comfortable home for rats. Walk through the French Quarter on a late night and you might notice a shadow dart along a wrought iron fence. Rats here do not hibernate or migrate, and between flood-prone areas, lush gardens and dense blocks of historic buildings, they have food, water and shelter all year.
Roof rats and Norway rats
Roof rats are agile climbers that nest above ground in attics, palm trees, ivy and eaves. They use wires, fences and branches as highways to reach roofs. Norway rats burrow low, in sewer lines, under slabs and at the base of foundations and dumpsters. Both are common in New Orleans, and house mice also appear in kitchens and storerooms. Their different habits mean the removal plan has to match the species.
Where they find a way in
Historic buildings have charm and gaps. Raised pier foundations leave open space under floors, while old cypress soffits, cornices and porch ceilings can be pried loose by determined animals. Banana, palm and fruit trees in courtyards offer food and cover. Shotgun houses packed close together give rats routes from one property to the next, and restaurants in the Quarter, Warehouse District and along Magazine Street produce grease and food waste. Drainage canals, flooded streets and construction after storms scatter the population into new areas.
Evidence indoors and out
- Thumps, scurrying or gnawing in attics and between floors, mostly at night.
- Droppings on beams, near pipes and in pantry corners.
- Greasy rub marks on the edges of beams and fascia boards.
- Gnawed fruit in the yard and chewed wires or pipe insulation.
- Burrow holes at the base of fences and walls.
The professional method
An inspector examines rooflines, soffits, vents, utility lines, trees touching the building and the ground beneath raised houses. Trapping is typical inside, and enclosed bait stations may be used outside. Exclusion is vital: mesh behind decorative vents, sealant at pipe penetrations, and trimming of branches that bridge to the roof. In historic properties, technicians often look for methods that keep original details intact. Sanitation of contaminated attic spaces may follow.
What homeowners can do
- Trim trees, palms and vines so nothing touches the house or roof.
- Pick up fallen fruit, pecans and bird seed daily.
- Use garbage cans with tight lids and keep them off the ground if possible.
- Seal gaps beneath raised houses with metal mesh without blocking ventilation.
- Store pet food indoors and remove standing water.
Keeping rats away from restaurants and neighbors
Rodent control in New Orleans works best when whole blocks participate. A single sealed home next to an overflowing dumpster will still see pressure, so talk with neighbors and nearby businesses about lids, grease containers and pickup schedules. Courtyard gardeners can help by harvesting fruit promptly and keeping compost covered. Such small habits across a block make a lasting difference to the local rat population.

How do I know if I have roof rats?
Noises overhead, droppings in the attic and gnawing high up on fruit trees suggest roof rats.
Will cleaning my yard stop the rats?
It helps by removing food and cover, but you also need to close entry points and remove the animals already inside.
Are rodents more active after storms?
Yes. Flooding and debris displace them, and they often move into buildings looking for shelter.
Is poison a good idea in an old house?
It can cause rodents to die in inaccessible spots, so many professionals prefer traps and sealing.
