Two species, two routes.
Florida has two rats worth knowing. The roof rat is a slender climber that nests up high in attics, soffits and palm crowns. The Norway rat is stockier, stays low and digs beside slabs, sheds and woodpiles. A single garage can host both.
The distinction decides where the technician looks first. Roof rats leave rub marks on wires and rails and droppings on flat roofs. Norway rats leave burrow holes about two inches wide beside walls and runways through grass.
Reading the yard before the attic.
Outdoor clues often explain indoor noise. A limb touching the roof works as a bridge, a fence beside the house is a highway and a feeder or windfall fruit is a diner.
| Yard feature. | Why rats like it. | What changes things. |
|---|---|---|
| Palm crown full of dead fronds. | Shelter and a nest site near the roof. | Have old fronds cut and keep the crown off the shingles. |
| Oak limbs over the roofline. | A bridge to the eaves. | Trim limbs back several feet. |
| Windfall fruit or nuts. | Food on the ground. | Gather it daily and bag it. |
| Bird feeder with spilled seed. | A nightly meal. | Add a tray or move the feeder far from the house. |
| Woodpile against the siding. | Cover along the wall. | Raise it on a rack and move it away. |
Choosing traps for the animal at hand.
Rats are suspicious by nature, so traps are set on confirmed routes and may stand idle for a day or two until the animals accept them. After that, traps are armed and checked on schedule, and enclosed stations keep kids and pets from touching the mechanism.
We avoid loose bait. Rats that eat poison can die in a wall or duct, and the odor lingers for weeks in warm weather. The dead rodent and odor page describes that outcome for anyone who has already tried bait.
Closing the roofline.
Rats chew through softer materials, so sealing means heavy mesh, flashing and metal collars rather than foam. The usual trouble spots are the gaps where roof meets wall, the ridge and gable vents, and any place a pipe or cable enters. See entry point sealing for the materials.
Sealing comes after trapping has cleared the building. Otherwise an animal can end up shut in a wall, where it dies and smells.
Mouse or rat? No need to guess. Describe the signs and we work it out.

- Store pet food and seed in sealed containers, and bring dishes indoors at dusk.
- Keep trash lids tight and rinse bins now and then.
- Prune shrubs so they do not press against the siding.
- Fix dripping spigots, since standing water draws animals.
These steps will not remove an established colony, but they cut the supply. Paired with trapping and sealing, they help keep results lasting.
Where cleanup and repair fit.
Heavily fouled insulation and droppings in the attic need cleanup, while gnawed wiring or ducts need damage repair. Neither starts until the animals are gone and each entry is shut.
Before you call: a careful routine for pellets and nests
The notes below restate guidance from public health agencies. They apply to any household, whether or not a visit is ever booked.
- Leave the broom in the closet. Bristles and vacuum exhaust both fling dry droppings into the air you breathe.
- Fresh air first, cleanup second: thirty minutes with the windows open is the CDC's starting point for closed spaces.
- Skin contact with droppings, urine or nesting material is avoidable, and gloves make it so.
- Dampen every pellet and stain completely and let the liquid stand before touching anything.
- One tied-off bag is enough for towels and a carcass together, and a second bag helps if the plastic is thin.
- We do not give medical advice, and anyone who feels sick after contact with rodent waste should see a clinician.
