Norway Rat Control in Miami
The Norway rat is the bigger, heavier cousin of the roof rat. It's brown, with small ears, a blunt nose and a tail shorter than its body, and it digs. UF/IFAS describes it as rare in Florida compared with the roof rat, so plenty of Miami homeowners never see one. When we do hear about them, the setting is usually low and damp.
Think burrows under a concrete pad, holes in a canal bank, or rats working a dumpster corral or grease bin. Ground floors, garages and the space under older raised houses are where they get inside. If the noise is in the ceiling, you probably want roof rat control instead.
Telling a Norway Rat From a Roof Rat
The quick test is where the signs are. Roof rats go up and Norway rats go down. Other differences:
- Tail shorter than the body, where a roof rat's is longer
- Thick body, small ears and a blunt snout
- Burrows along slabs, foundations and banks, often with packed dirt at the mouth
- Droppings bigger and blunter at the ends than a roof rat's
- Activity in the garage, the trash area or the yard more than the attic
Where They Show Up in Miami-Dade
Seawalls and canals give them water and cover. So do overgrown lots, woodpiles and junk stacked along a side yard. Commercial strips are the other hot spot. The alley behind a row of restaurants, with its grease bins and dumpsters, can support a colony that spills into the houses behind it. People in Little Havana and near the busy roads of Hialeah know the pattern.
Businesses dealing with this usually need a standing program with exterior stations and a service log. See commercial rodent control.
Noises in the ceiling or chewed fruit in the yard? One call puts you through to a licensed provider who works your part of Miami-Dade.
How the Provider Handles Burrows
The tech maps the burrows and the runs, sets traps where the rats travel and, if bait is part of the plan, uses anchored tamper-resistant stations. Burrows get watched. Once one goes quiet, it gets filled and packed. Anything that lets rats into the garage or under the house gets closed with metal and concrete.
Leave the burrows open until the tech has seen them. Open holes show how big the colony is and where it's coming from. In the meantime, lock down the trash, rake up fallen fruit and get stored things up off the ground.
Questions From Callers
Do Norway rats get into attics?
They can climb but rarely bother. If something is living in your attic in Miami, it's almost surely a roof rat.
Should I fill the burrows myself?
Not yet. Let the provider see them first. They get filled once they're no longer in use.
