Why sealing the house beats poison alone
Traps and bait reduce the rats you have today. If the vent screen, roof return or pipe gap they came through is still open, new rats move in. That is why exclusion work goes in this order: inspect every opening, remove the rodents already inside, then seal the house so they can’t come back.
- Inspection: a walk of the roofline, attic, garage and foundation with photos of each opening.
- Removal: trapping, with follow-up visits until activity stops.
- Exclusion: hardware cloth, vent screens, sealant and door sweeps over every entry point.
- Cleanup: droppings, nests and contaminated insulation, if the attic needs it.
Poison in an attic or wall can leave a dead rodent where you can’t reach it. Ask any contractor how they handle removal before you hire.

Roof rats can squeeze through openings larger than a quarter inch, according to the University of California’s IPM program. These are the openings an inspection should check:
- 1Roof and gable ventsTorn or rusted screens are the most common way roof rats reach an attic.
- 2Roof returns and eavesSmall gaps where roof lines meet are hard to see from the ground.
- 3Pipe, AC and cable penetrationsOpenings around lines entering the house are often left unsealed.
- 4Garage door corners and sealsWorn bottom seals and gaps at the corners let rodents into the garage.
- 5Foundation and crawl-space ventsDamaged vent screens give rats and mice access under the floor.
- 6Tree limbs, ivy and fencesThese act as runways to the roof; UC IPM advises pruning limbs within 6 feet of the roof.

Check any contractor before you hire

Confirm the company’s license with the appropriate California board, such as the Structural Pest Control Board or the Contractors State License Board.
Common questions
Who do I call to get rid of rodents in my house?
Call a pest-control or rodent-exclusion contractor that inspects the whole house, traps the rodents already inside, and seals the openings they use. Ask for a written inspection report with photos of each entry point before you agree to a plan. You can call the number on this page or send the form, and your request goes to an independent local contractor.
How much should it cost to get rid of rats?
National cost guides put professional rat removal at roughly $189 to $655 (HomeAdvisor, 2026) and sealing entry points at roughly $200 to $600, with larger whole-home exclusion plans running higher. Attic cleanup and insulation replacement are separate. See our cost guide for the full table and sources; the contractor sets the final price after an inspection.
Will pest control help with exclusion?
Not always. Many pest-control plans are bait stations or traps on a monthly schedule, which reduce rodents but don't close the gaps they use. Exclusion is the work of sealing vents, roof returns, pipe penetrations and garage door gaps so new rodents can't get in. Ask any company you call whether sealing entry points is included in the quote.
Does seeing one rat mean an infestation?
Not necessarily, but rats rarely travel alone, and roof rats in particular move along fences, trees and power lines at night. If you also hear scratching overhead, find droppings, or see gnawed fruit, have the house inspected. Our signs-of-rats guide explains what to look for.
