Rodents in Louisiana Homes — Signs You May Have Mice or Rats Indoors
During the cooler months in Louisiana, it’s common for mice and rats to look for warm, sheltered places to live — and sometimes that means inside your home. Rodents don’t need much space to squeeze in, and once they find food or nesting material, they tend to stay.
At Big Easy Pest Control, we help homeowners across Louisiana identify and eliminate rodent problems before they get worse. Here are the most common signs that mice or rats may already be inside your home.
Scratching or Movement Sounds at Night
Rodents are most active after dark. If you hear:
Scratching
Chewing
Scurrying
coming from walls, ceilings, attics, or under floors, that can be a strong indicator of rodent activity.
Droppings Around the Home
Rodent droppings are one of the clearest signs of an infestation. You may find them:
Inside cabinets
Near food storage
Around appliances
Inside pantries
In attics or garages
Fresh droppings are usually dark and soft — older ones become gray and crumbly.
Gnaw Marks or Damaged Packaging
Mice and rats constantly chew to keep their teeth worn down. You may notice:
Chewed food bags or boxes
Gnaw marks on wood or plastic
Shredded paper, insulation, or fabric used for nesting
If you see small piles of chewed material, there’s a good chance rodents are nearby.
Grease or Rub Marks Along Walls
Rodents tend to travel along the same paths every day. As they move, the oils in their fur may leave dark smudges or streaks along baseboards, walls, or entry points.
Strange Pet Behavior
Dogs and cats often detect rodents before humans do. If your pet is suddenly fixated on:
Walls
Under appliances
Attic access points
…it could mean they’re smelling or hearing something you can’t.
Why Rodents Are a Problem
Rodents aren’t just a nuisance — they can:
Contaminate food areas
Damage insulation and wiring
Create unpleasant odors
Multiply quickly
So a small problem can become a big one before you know it.
How Do Rodents Get Inside?
In Louisiana, rodents often enter through:
Gaps in roofing or soffits
Cracks around foundations
Openings around pipes or AC lines
Poorly sealed doors or garage spaces
Tree branches touching the roof
And mice can squeeze through openings as small as a dime.
Simple DIY Steps You Can Try First
There are a few things homeowners can do to reduce activity:
Seal up obvious gaps around doors and pipes
Store all food (including pet food) in sealed containers
Clean crumbs and spills quickly
Remove clutter rodents might use for nesting
Trim tree branches touching the roof
Traps may also catch a few rodents, but keep in mind — this usually only offers temporary relief.
If nests, hidden entry points, or multiple rodents are present, DIY methods rarely solve the problem completely. That’s exactly why Big Easy Pest Control is here — to help fix the root cause so the problem doesn’t keep coming back.
When Should You Call a Professional?
If you’re seeing:
Frequent droppings
Repeated scratching sounds
Multiple sightings
Or ongoing activity
…it’s time to get help.
DIY traps may catch some, but rarely solve the root problem — especially if there are nests or multiple entry points.
