The first sign of mice in your ceiling or attic will be the sounds. You'll hear the skitter of their little claws across your ceiling tiles or occasional squeaks. Gnawing and digging sounds are additional signs of an infestation. Since mice are nocturnal, these sounds will be most evident at night.
Soft Slow Moving Scritching
Slow moving scratching noises can indicate a snake in the attic.
Set snap traps along the mouse trails. Along ceiling joists, set two traps side by side, with baits at opposite ends, putting bait in front of mice traveling either direction. When using a single trap, place the baited end against the joist.
You can also install a one-way trap so that once an animal leaves the attic, it cannot get back in again. Live trapping is the most humane and effective way to remove animals; however, it's almost impossible for a homeowner to successfully remove a large infestation of rodents or bats.
Look at photos of Raccoon Feces, or Squirrel Feces, or Rat Feces, or Mouse Feces, or Bat Feces. You can also look at the animal tracks left in the dust in the attic. Check on almost any surface not covered by insulation, and there should be a layer of dust with animal tracks. Or you can check for muddy footprints.
Rats and Mice

If you are inspecting a dusty area or crawl space, you might notice slither tracks that indicate where a snake has traveled. Snakes have a distinctive smell that is noticeable.
Signs That Animals Are in Your Walls
Mice and rats are nocturnal, so you'll most likely hear scratching in walls once the sun has set and the house has quieted down. Squirrels, on the other hand, are diurnal, meaning they're awake and active during the day.
The most common cause of scratching noises at night are rodents. These noises usually come from the places where rodents most often live. This could be your walls, ceilings, beneath floorboards, piles of mice attracting clutter or in your kitchen or attic. Rodents love to nest in these areas.
Look for gnaw marks in your property, especially on the roof or at access points, and nests are a sign that a colony may be present. Rats also leave greasy/dirty trails and are also notorious for damaging electrical wires, so look for any damage to them.
It generally takes roughly 3 days to one week to get rid of rats with rat poison. Mechanical traps can sometimes take a few days to trap rats because the rodents may be wary of the trap. A pest control professional can remove rats in as little as one day to a few days depending on the size of the infestation.
Rats make a combination of squeaking, hissing, and chattering sounds. They can communicate different emotions depending on the frequency of the noise. Often, squeaks or hisses signify that a rat is afraid or in pain. The pests also chomp and grind their teeth.

House mice are also notorious for making scratching and scuffling noises as they move behind baseboards, drywall, and floorboards in homes. These sounds are caused by the pests' nails digging into surfaces for grip.
Scratching may come from a bird, mouse, rat, or possum. Scratching sounds can be indicative of a bigger problem. The sound of a scurrying mouse is almost continuous, while a rat running has a more distinct sound from the impact of their paws.
