Norway Rat Removal in Orlando, FL

How to recognize a Norway rat problem

The clearest sign is the burrow itself. Norway rat burrows are two to four inches across, usually found against a foundation wall, under a slab edge, beneath a shed or deck, or in dense ground cover. An active burrow has a smooth, worn entrance and often a fan of loose soil outside it. Homeowners frequently mistake them for animal holes of some other kind, and it is worth looking properly before assuming.

Indoors, the noise is at floor level rather than overhead, which is the fastest way to distinguish the species without seeing the animal. Sounds from a crawl space, from beneath the floor, from a garage, or from the base of a wall point down rather than up. The movement also sounds heavier than a roof rat, and homeowners often describe dragging or rolling rather than light scurrying.

The droppings are larger than a roof rat leaves, up to three quarters of an inch, with blunt rather than pointed ends. Gnaw damage at the bottom corners of garage doors, at the base of exterior doors, and around utility penetrations low on the wall is characteristic.

How Norway rats get in at ground level

The routes are entirely different from a roof rat and they are why a company that only knows attic work will struggle. The most common are gaps at the bottom corners of a garage door where the seal has worn, uncapped or damaged foundation and crawl space vents, the gap around a utility penetration where a pipe or conduit enters below grade, and damaged sewer laterals, which is a genuinely underrated route in older Orlando neighborhoods.

Crawl spaces under older Central Florida homes are a particular weak point. Many were screened decades ago with material that has since rusted or torn, and the space under the floor then becomes a sheltered, undisturbed nesting area with easy access to the underside of the structure. Discussions among homeowners dealing with burrowing rats in crawl spaces repeatedly warn against half measures like shallow trenching, and the approaches that hold up are proper perimeter screening carried below grade or a poured barrier.

Because the animal digs, exclusion here has to account for what is underground. Screening that stops at the soil line is an invitation to go underneath it. Effective work carries hardware cloth down and outward in an L shape below grade, which is more labor than an attic seal and is priced accordingly.

Why the treatment approach is different

With a roof rat, closing the roofline is decisive because there is a finite set of openings and the animal cannot make a new one easily in a properly sealed structure. With a Norway rat you are also managing the ground around the building and the conditions that make it attractive, so the work extends past the structure itself.

That means burrow treatment and collapse, removing harborage such as dense ground cover against the foundation, woodpiles and unused materials stored on soil, and dealing with the food source that is sustaining the population. A property that keeps chickens, feeds pets outside, or has fruit dropping and rotting beneath a tree will keep drawing rats regardless of how well the structure is sealed, and any company that does not raise this with you is not going to solve your problem.

It also means the timeline is often longer. Trapping a burrowing population is slower than trapping an attic population, because the animals have somewhere to retreat to that you cannot reach and they are more cautious about new objects on established runs.
