Rat Exterminator Cost Calculator (2026)
By Marcus Ellery, Pest Control Editor · Updated September 2026
A rat exterminator costs about $170 to $600 for basic trapping, and $400 to $1,100 once you add exclusion (sealing the entry points) so the rats do not come back. Heavy jobs that need attic cleanup after nesting can run toward $1,500 to $2,000. Rats are larger and more cautious than mice, enter through bigger gaps, and often set up in attics or crawlspaces, so trapping and sealing both take more time and materials than a mouse job. Rat pressure also climbs as the weather cools and they move indoors for winter, so early action is cheaper. Estimate yours below.

What drives your rat exterminator cost
- Service level: trapping is cheapest; exclusion sealing prevents costly re-infestation.
- Rats vs. mice: rats are larger, more cautious, and enter through bigger gaps, so they usually cost more.
- Home size & access: attics, crawlspaces, and wall voids add inspection and sealing labor.
- Damage & cleanup: heavy nesting means droppings, chewed wiring, and decontamination.
- Follow-up: a monitoring plan re-checks traps and seals until the home is clear.

Ways to save
- Pay for exclusion sealing: trapping alone lets rats return and re-billing adds up.
- Seal obvious gaps (around pipes, vents, garage, roofline) yourself before the visit.
- Act before winter: rats move indoors as it cools, and a small problem is far cheaper than an established colony.
- Remove food sources and outdoor clutter to speed up removal.
- Ask whether the quote includes a return guarantee if rats come back.

Frequently asked questions
How much does a rat exterminator cost in 2026?
Basic rat trapping runs about $170–$600. Removal plus exclusion (sealing entry points) costs $400–$1,100, and jobs that add attic cleanup or decontamination can reach $2,000, depending on home size and how established the colony is.
Are rats more expensive to exterminate than mice?
Generally yes. Rats are larger, more cautious about new traps, and squeeze through bigger gaps, so trapping and exclusion take more time and materials than a comparable mouse job.
Is exclusion worth the extra cost for rats?
Usually yes. Trapping removes the current rats but does nothing to stop new ones. Exclusion seals the entry points, which is the difference between a one-time fix and a recurring bill every few months.
Why do rat problems spike in fall and winter?
As outdoor temperatures drop, rats move indoors toward warmth, food, and nesting sites, so activity climbs from roughly October through February. Sealing entry points before the cold season keeps the job small.
