Few things are more unsettling than footsteps overhead at midnight. The cause may be a rodent, but it could be something else. This guide helps you read the clues and decide what to do.
What the sounds can tell you.
Scratching and light scurrying often suggest mice. Heavier thumps and running steps that cross the ceiling suggest rats, especially roof rats at dusk. Gnawing is a rhythmic sound, and rolling noises can mean an animal is moving objects.
Time matters too. Rodents mostly move after dark, and squirrels and birds keep daytime hours. If the noise is at midday, rodents are less likely, although not impossible.
Other things that can make noise.
| Source. | Typical sound. | Clue. |
|---|---|---|
| Mice. | Light scratching, scurrying. | Small pellets, gnaw marks. |
| Roof rats. | Heavy steps, thumping, gnawing. | Larger droppings, rub marks, steps at dusk. |
| Squirrels or birds. | Daytime scampering or fluttering. | Noise in daylight, nesting at vents. |
| Pipes and ducts. | Ticking, banging with temperature changes. | Sound follows heating or cooling cycles. |
| Wind or loose roofing. | Rattling or tapping. | Noise matches weather. |
What to do before you go into the attic.
Attics in Florida can be dangerously hot, and they may contain droppings. Air out the space, wear gloves and avoid stirring dust. If you can look from the hatch with a flashlight, do that first. Look for pellets, nests, torn insulation and gnawed wiring.
- Open the hatch and wait before entering.
- Wear gloves and avoid touching soiled material.
- Leave dry droppings unswept and unvacuumed.
- Take photos of what you see.
- Do not disturb nests.
Finding where they get in.
Outside the building, look at the roof edge, soffits and vents. Check for palm fronds or limbs touching the roof, and look at wires that run to the house. Roof rats often enter at the roofline, and mice may use gaps around pipes or at the garage.
Our rat control page explains how roof rats are handled, and the mouse control page covers small gaps and trapping.
The right order of work.
Trap first, then seal, then clean. If you close gaps before the animals are out, they may be trapped inside and cause odor. Once they are gone and the entries are shut, attic cleanup removes soiled insulation and treats the space.
Mouse or rat? No need to guess. Just describe the signs.

Before you call, spend a few nights keeping a short log. Write down the time the noise starts, where in the house you hear it and what it sounds like. Patterns appear quickly. Noise that begins at dusk and moves along one wall suggests a regular route, while a single bang at midnight may be a loose item or a cooling pipe.
| Night. | Time heard. | Place. | Sound. |
|---|---|---|---|
| First night. | Around dusk. | Over the bedroom. | Running steps. |
| Second night. | After midnight. | Along the north wall. | Light scratching. |
| Third night. | Near dawn. | Over the kitchen. | Gnawing, then quiet. |
That sort of log gives a technician a head start. It shows whether activity is heavy or light, whether it moves and which part of the building to open first.
Why attics matter in a humid climate.
An attic in coastal Florida is hot and often damp. Insulation soaks up moisture and odor, and droppings can build up in it. Even when the animals are gone, the space may need attention. The cleanup page explains how soiled material is removed and the space treated.
When to call.
If the noise returns night after night, or you find droppings, call. An inspection can name the animal and show where it enters. Tell us what time the noise starts and what it sounds like.
Safe handling of rodent waste and nest debris
Thinking of tidying before the visit? Take the steps in order, and pause at any that seems unclear.
- Anything dry stays off the brush and out of the vacuum.
- Open every door and window that will open, then wait thirty minutes before starting.
- Keep your hands covered the whole time, then lather well.
- Timing matters: wet the waste, let it rest about five minutes and only then wipe, so dust stays down.
- Tie the bag firmly before carrying it out, and wear a hand barrier whenever a carcass has to move.
- We make no medical claims. Fever, aching all over or labored breathing after handling waste is a matter for a doctor.
Where the safety steps come from
Agency guidelines stand behind every safety statement here, and each comes with a line about its contents.
- CDC advice on cleaning rodent droppings and nests: Contact time for the disinfectant, which protective gear to wear and where the bagged waste goes.
- EPA rules for rodenticide products: Rules for consumer rodenticides, handy when you are comparing store-bought products.
