It is 2 a.m. and something is moving over your head. Scratching, a soft patter, then a pause, then a dull roll. Most people lie still and wonder. A few notes taken in the morning can turn that guessing into a useful phone call, so this guide shows what to listen for and what to write down.
Listening like a technician.
Sound carries through framing in odd ways, so do not trust a single impression. Still, patterns help. We ask callers about four things: the type of sound, the time, the place and how long it has been going on.
| What you hear. | What it can suggest. | What to note. |
|---|---|---|
| Light, quick scratching in a wall. | Mice working along a stud bay. | Which wall and what hour. |
| Soft patter across the ceiling. | Small feet moving in the attic. | How often and for how long. |
| Heavy thumps or dragging. | A larger animal, possibly a rat. | Where it starts and stops. |
| Gnawing, a steady rasp. | Chewing on wood or wire. | Whether it stops when you move. |
| Ticking or popping at dusk or dawn. | Framing and ducts changing temperature. | Whether it tracks the heating cycle. |
What to write down.
- The room below where you hear the sound.
- The time it starts and the time it fades.
- Whether it occurs nightly or only once the temperature falls.
- Whether it is in a wall, a ceiling or both.
- Anything you smelled or saw, including droppings or stains.
Keep the note short. A week of lines with dates and times is plenty.
How animals get to the attic.
Attic visitors rarely come through the front hatch. They climb along trees, wires and rough siding and enter at the roofline, through a loose vent cover, a gap behind fascia or a chimney flashing that has lifted. Some enter from lower down and travel up inside a wall.
In a region with cold winters, the attic is also a warm, quiet shelter. Heat that leaks upward from the living space keeps it milder than the outdoors, and insulation makes a ready bed. That is why attic noises often begin after the first hard frost.
Pass along your street plus a few details, and the dispatcher hunts for the soonest slot.
Dial (888) 686-4821Looking without making it worse.
You can learn a lot from the hatch. Lift it a few inches, shine a flashlight across the floor and look at the insulation. Do not step in and do not pull insulation out.
- Flattened trails or tunnels in the insulation.
- Dark pellets scattered near the edges.
- Nest scraps of shredded paper, cloth or insulation.
- Daylight at the roof edge or a vent that looks loose.
- Stains on the ceiling below that suggest moisture or urine.

Why not go in yourself.
A closed attic holds dust, and rodent droppings dry into fine particles. Walking through them lifts that dust into the air you breathe. The CDC advises airing out closed spaces first and using wet methods, not dry sweeping. A nest also holds young animals that may bolt if disturbed.
If you must enter for any reason, open the hatch and let the space air out for about half an hour, wear gloves and a mask, and move slowly. Better still, wait for a visit.
What a visit does about it.
The search begins outdoors, since the entry is out there. Then we look at the attic itself, mark the routes and place traps where the evidence shows traffic. Sealing follows once the catches slow, and cleanup comes last. Our inspection page shows how the walk-through is built.
If insulation is soiled or flattened, cleanup is a separate step. For gnawed wiring, we point you to an electrician and list the damage in our repair scope.
A last word on limits.
This guide cannot name the animal above your head. It can help you describe it and keep you safe while you wait. If you are unsure, call and tell the dispatcher what you heard and when.
Before you call, deal with droppings the wet way
Moving slowly keeps fine particles out of the air you breathe.
- Fast, hard scrubbing lifts dust, so go gently and keep everything wet.
- Open the doors and windows first, and give the space about thirty minutes of fresh air before anyone starts work.
- Cover your hands during the job and scrub them with soap and running water once it is done.
- Keep spraying until nothing looks dry, then leave the room for a few minutes.
- Bag whatever you collect before it travels anywhere else, and knot the top.
- Medical questions are outside what we can answer. Feeling unwell after contact with droppings is a reason to see a clinician.
Verify it with the agencies
Cleanup and poison rules were written by federal agencies, whose pages follow.
- EPA limits on rodenticide products: Rules covering rodenticides sold to consumers, including the enclosed bait station requirement.
