Rats are a structural problem as much as a pest problem. They gnaw wiring, contaminate insulation and food, and reproduce fast enough that a delay of a few weeks materially changes the scale of the work.

Effective rat control is roughly one part trapping to two parts exclusion. Removing the rats currently inside without sealing the gaps that let them in simply creates a vacancy for the next ones.

Roof Rats vs Norway Rats

Roof rats

Slim, agile climbers with a tail longer than the body. They nest high — attics, rafters, palms — and enter via rooflines, vents and overhanging branches. Common across the South, Gulf and West Coast.

Norway rats

Heavier and stockier with a shorter tail. They burrow, nesting in basements, crawl spaces and under slabs, and enter at ground level. Dominant across the Northeast and Midwest.

Droppings

Roof rat droppings are around half an inch with pointed ends; Norway rat droppings are larger with blunt ends. This is often the quickest way to tell which species you are dealing with — and therefore where to seal.

Rub marks and runways

Rats follow the same routes repeatedly, leaving greasy dark smears along walls and beams. Those runways are exactly where traps belong — trap placement matters more than trap type.

Sounds

Scratching and scurrying overhead at night suggests roof rats; noises from below floor level or in basements point to Norway rats.

What Professional Rat Control Involves

Inspection and species ID

The technician traces droppings, runways and rub marks to establish the species and, critically, the entry points being used.

Trapping

Snap traps placed along established runways, not in open floor space. Professionals generally favour trapping over rodenticide indoors, because a poisoned rat dying inside a wall void creates an odour problem lasting weeks.

Exclusion

Gaps sealed with steel wool, hardware cloth, sheet metal or mortar — materials rats cannot chew. A rat passes through any gap that admits its skull, roughly half an inch. This is the step that determines whether the problem returns.

Sanitation and clean-up

Contaminated insulation and droppings are removed and the area disinfected. Rodent droppings can carry pathogens, so this is protective work rather than cosmetic.

What rat treatment costs

$200–$800

for removal and exclusion

What moves the price:

Extent of exclusion work — this is usually the largest component
Whether attic or crawl-space clean-up and insulation replacement is required
Number of follow-up visits to confirm activity has stopped
Property size and how accessible the entry points are

These are typical national ranges, not quotes. Pricing depends on your property and the severity of the problem.

Where DIY Falls Short

Traps bought retail work perfectly well — the failure is almost always placement. Traps set in open areas rather than along established runways catch very little, and rats quickly learn to avoid disturbed areas.

The bigger gap is exclusion. Finding every entry point on a structure takes experience, and rats exploit gaps most people never think to check: utility penetrations, roof-junction gaps, weep holes and the space behind fascia boards.

Common questions

How much does a rat exterminator cost?

Typically $200–$800 for removal plus exclusion. Simple trapping sits at the lower end; extensive sealing work, attic clean-up or insulation replacement pushes toward the upper end and beyond.

How long does it take to get rid of rats?

Most infestations are resolved in two to four weeks: an initial visit, trap checks over the following week or two, and a final confirmation once activity stops. Exclusion work is usually completed alongside.

Should I use poison for rats?

Most professionals avoid rodenticide indoors, because rats frequently die inside walls and create a severe odour problem. It also poses risks to pets and to predators that eat poisoned rodents. Trapping plus exclusion is the standard approach.

How are rats getting in?

A rat can pass through a gap of roughly half an inch. Common routes are utility penetrations, gaps under garage doors, roof-junction gaps, uncapped vents and damaged soffits. Which routes to check depends on the species.
