Two kinds of rats around Mount Dora.
Roof rats are the more common problem close to downtown and the lakefront, since they are strong climbers. They use tree canopy, power lines, and overhanging branches to reach a roofline before working their way into an attic through a gap at the eave or a vent screen that has rusted through. Norway rats tend to stay lower, digging burrows along foundations, under sheds, and in dense ground cover, and they show up more often in yards with mature landscaping or a woodpile that has not been moved in a while.
Telling the two apart matters for where we look first. A roof rat problem usually starts in the attic and works down, while a Norway rat problem usually starts at ground level and only reaches the house if a foundation gap gives it access. On the call, tell us whether the noise is overhead or closer to the ground, since that alone often points to which species we are dealing with.
Inspecting attics, foundations and fence lines.
A technician checks the attic first for droppings, grease marks along rafters, and gnawed wiring, then works outward to the roofline, the soffits, and any tree limbs that touch the house. At ground level we look at the foundation perimeter, gaps under a shed or deck, and burrow openings near fences or dense shrubs. Rodent Inspection and Estimates covers this walkthrough in detail if you want a full map of activity before committing to a treatment plan.
Trapping rats safely.
Rodent Trapping and Removal for rats uses larger snap traps and secured bait stations placed along the exact travel routes found during inspection, not scattered around the property. Roof rat traps often go inside the attic itself, along the rafters or near the entry gap, while Norway rat traps go along foundation lines and near burrow openings. We check every placement on a schedule rather than leaving it to chance.
Rat burrows can be extensive underground, so removing a visible entrance is not the same as clearing the burrow system behind it. We look for secondary openings nearby, since an abandoned-looking burrow sometimes has an active side entrance a few feet away.
Sealing the way in.
Rats can gnaw through material that would stop a mouse, so sealing uses heavier hardware cloth and metal flashing at rooflines, vents, and gaps where utility lines pass through an exterior wall. Roof rats specifically need any tree limb within about three feet of the roof trimmed back, since that gap is often enough to stop them from bridging onto the structure at all.
A rat problem outdoors becomes an attic problem the moment a branch touches the roof.
A yard-level rat problem is sometimes mistaken for a smaller concern than an attic problem, but an established burrow system near a foundation can eventually give rats a path indoors even without an obvious roofline entry point, particularly around an older slab with settling cracks. Treating ground-level activity early tends to be simpler than waiting until it has had time to grow into something larger and harder to fully clear.

Mount Dora's mature oak canopy is part of what gives the city its character, but it also gives roof rats an easy path onto a house that a treeless yard would not. Homes near Palm Island Park and other green, tree-lined areas tend to see more calls for this reason. We do not ask anyone to remove healthy trees, but trimming limbs back from the roofline is one of the most effective, low-cost steps a homeowner can take between visits.
Rats and commercial properties near downtown.
Restaurants and shops along Donnelly Street and the surrounding blocks deal with a version of the same problem, usually tied to dumpsters, outdoor seating areas, or deliveries left unattended overnight. Commercial Rodent Control covers ongoing monitoring for businesses that need documentation and a regular schedule rather than a one-time visit, which matters during the busiest festival weekends when foot traffic and food waste both climb.
After the visit.
We return to check traps and confirm sealed points are holding. If activity continues at ground level after an attic problem is resolved, that usually points to a separate Norway rat population working the yard independently, which we treat as its own job rather than assuming it will resolve on its own. A second visit is always about confirming the work held, not starting over.
| Sign | Likely species |
|---|---|
| Noise mostly in the attic at night | Roof rat, using the roofline to enter. |
| Burrow openings near a foundation or shed | Norway rat, working at ground level. |
| Grease marks along a fence top or wire | Roof rat, using it as a travel route. |
| Gnawed vegetable garden or fallen fruit | Norway rat, foraging near ground cover. |
