You open a drawer for a spoon and find a scatter of dark pellets. Your first reaction is probably to grab a broom. Resist it. The right first hour is calm and methodical, and it protects both your family and the evidence a technician needs.
Minute one: stop and look.
Do not touch anything yet. Look at what you see: how many droppings, where they are concentrated, whether they look fresh or old. Dark, shiny pellets are recent, and gray, dry ones are older. A cluster in one spot suggests a resting or feeding site, while scattered pellets suggest travel.
- Count roughly: a handful, dozens or more.
- Note the size: mouse pellets are small and pointed, rat pellets larger and blunter.
- Look for gnawing on packaging, soap or wood.
- Check for greasy smears along edges.
- Notice any odor: ammonia suggests living animals.
Minutes five to fifteen: photograph and map.
Take photos with a coin beside the droppings for scale. Photograph the drawer, the cabinet and any chewed items. Then sketch the kitchen and mark where you found signs. The pattern will help the technician decide where animals travel.
Check the usual suspects with a flashlight: under the sink, behind the refrigerator, beside the range, in the pantry and along the base of the wall. Add them to the sketch. If signs appear in the garage too, note that.
Minutes fifteen to forty: protect the household.
Move children and pets out of the kitchen. Put away open food in glass or hard plastic. Wipe counters. Pull out the pet bowl overnight. These steps will not remove animals, but they remove the easy meal.
Avoid poison. A mouse that eats bait can die in a wall and create an odor and a cleanup job. Loose bait is also a hazard for children and pets. The EPA link at the end explains why consumer products come with restrictions.
Minutes forty to sixty: clean the right way.
If you decide to clean, follow the wet method. Open windows and doors and leave the room for about thirty minutes. Put on rubber or disposable gloves. Use a household disinfectant, or one cup of bleach in nine cups of water, to drench the droppings and the surface beneath them. Give it five minutes to work.
| Step. | Do. | Do not. |
|---|---|---|
| Air out. | Open windows for half an hour. | Walk in and start sweeping. |
| Gear up. | Wear gloves, and a mask for larger messes. | Handle pellets bare-handed. |
| Wet. | Soak droppings with disinfectant. | Spray dry and wipe right away. |
| Wipe. | Use paper towels, then bag them. | Reuse a sponge or rag. |
| Wash. | Scrub hands with soap and warm water. | Rely on sanitizer alone. |
Place used towels, gloves and waste in a sealed bag, then in a second bag before it goes in an outdoor bin. The CDC box on this page restates the method in full.

(818) 791-1810What to leave for the technician.
If you clean everything, you erase some of the evidence. Keep photos and your sketch, and leave a few pellets in an untouched corner if you can. Many technicians read droppings to judge species and activity, and the pattern says a lot about travel routes.
- Do not close up any hole you find without telling the technician.
- Do not set several traps at random.
- Do not use mothballs or strong scents, which rarely change animal behavior.
- Do keep a note of dates and times of any new signs.
Why the drawer, specifically.
Drawers and cabinets near the range or sink are warm, dark and full of crumbs. They also connect to wall cavities through gaps around pipes and wires. A mouse that enters from a plumbing gap under the sink can reach every cabinet in a row.
This is why the inspection follows the signs back to the entry. See the mouse page for how that goes, and the inspection page for the contents of the written estimate.
When to call.
Call if you see fresh droppings after cleaning, hear scratching in the walls, find chewed wiring or smell ammonia. Call the same day if you find a nest, if the animal is visible in daylight or if the signs are spreading to other rooms.
A person is on the line around the clock, and a same-day slot goes to the first caller when the schedule has space.
Federal cleanup advice, condensed.
Many homeowners handle small cleanups themselves, even when a technician is on the way, so keep these precautions nearby.
- Sweeping, air hoses and vacuums throw invisible grit where you breathe.
- Fresh air thins whatever is hanging in a sealed room, so let it work while nobody is inside.
- Gloves belong on your hands before you touch the spray bottle.
- Let the liquid sit for around five minutes; the wait does the disinfecting.
- Knot the bag firmly and put it in an outdoor bin with a lid.
- Swap into clean clothes before you sit down to eat.
