The part of the job that lasts.
Rodents come in because something invites them and something lets them. You can reduce what invites them with food storage and yard habits, but only sealing removes what lets them in. A house with no gaps is a house they cannot enter, whatever is outside.
A mouse needs only a quarter inch, and a rat roughly half an inch. That is smaller than most people picture, and it explains why a house that looks tight can still have ten or twenty working openings.
Where openings usually are.
| Location. | Common gap. | Material we use. |
|---|---|---|
| Roof edge and returns. | Gaps between roof and wall or under edge tiles. | Metal flashing and stop strips. |
| Attic and wall vents. | Torn or missing screens. | Metal mesh or hardware cloth. |
| Pipe and wire entries. | Rings around lines that pass through walls. | Mesh packed in and sealed. |
| Garage door. | Worn bottom seal, gaps at the corners. | New seal, threshold repair. |
| Foundation and slab edges. | Cracks and weep holes. | Mesh covers and sealant. |
How the sealing is planned.
The list comes from the inspection, not from a template. Rub marks and droppings show which openings are in use, and those are closed first. Lesser gaps follow, in order of how likely an animal is to find them.
Work often starts at the roofline and ends at the ground. Roof rats use high routes, and mice use low ones, so a full job covers both. The technician explains the order and the materials before beginning.

Vail is an unincorporated community in Pima County, and the Rincon Mountains District of Saguaro National Park lies near it. For homes close to open ground, the lot boundary matters as much as the roofline. If your community has rules about exterior changes, tell us, because sealing may touch trim or vents.
Summer heat is hard on sealants and on people. Work that involves the roof or the attic is best planned for the cooler parts of the day, and the technician will say if a job should wait.
What you can do before the visit.
- Note any gap, vent or corner that looks worn or open.
- Leave existing seals and screens alone so the technician sees them as they are.
- Clear stored items from the garage wall nearest the door.
- Tell the technician about any recent roof, plumbing or electrical work.
Sealing is often the last step before cleanup. After that, attic and crawl space cleanup and rodent damage repair handle what the animals left. If you are still hearing noises, return to rodent trapping and removal first.
Cleanup safety, drawn from CDC guidance
These steps follow CDC guidance on cleaning up after rodents. They are general safety practice for any household.
- Do not sweep or vacuum dry droppings or nests. That can put contaminated dust in the air you breathe.
- Ventilate a shut-up space first. Half an hour of airing out is the CDC's starting point.
- Hand protection matters. Wear gloves throughout and wash your hands with soap afterward.
- Soak, wait about five minutes, then wipe. That order keeps dust down and gives the disinfectant time to work.
- Seal used paper towels and any dead rodent in a bag before disposal. Keep bare skin out of it.
- Flu-like symptoms or shortness of breath after rodent exposure are a reason to see a doctor and mention the cleanup. Health questions belong with a physician, not a pest company.
