Rat Exterminator Cost vs. DIY: Rat and Mouse Prices
Illustration: a printed estimate on one side of the table, DIY supplies on the other.
Price guides put a rat job at $189 to $655 (HomeAdvisor, June 2026), but that usually buys trapping alone. Jobs that also seal the gaps, which is what stops rodents coming back, had a $2,000 median across 53 quotes homeowners shared on Reddit for mice or rats, with the middle half at $1,400 to $3,000. Doing it yourself costs about $57 to $71 for mice or $65 to $87 for rats. Start with traps tonight; pay a pro for ducts, high rooflines or a heavy infestation, and skip plans you can’t total.
Cost: about $57–87 in supplies. Difficulty: moderate. Call a pro if rodents are in your heating or cooling ducts, droppings cover a large area, or new droppings and gnawing keep turning up after at least 15 days of trapping and re-baiting.
This guide compares the ways to buy the job, from a one-time pro visit to a monthly plan to doing it yourself, and shows how to tell whether a quote is too high. We haven’t hired or priced these companies ourselves; this rests on HomeAdvisor, This Old House and Orkin’s published prices, 100 rodent quotes homeowners posted on Reddit, CDC and extension guidance, and store list prices.
Saw a rat or mouse tonight? Check droppings first: rice-grain size means mice, raisin size means rats, so buy that size of snap trap. Bait each with a dab of peanut butter. Set them on the floor, baited end against the wall in a “T”, where you found droppings, behind the stove and fridge, or at the back of a cabinet where kids and pets can’t reach. Wear gloves, and don’t sweep or vacuum droppings: spray them with 1.5 cups of bleach in a gallon of water, wait 5 minutes, then wipe them up with paper towels.
How We Compared Pro and DIY Costs
We compared each way of buying the job on four things:
- Total cost: national ranges, not one company’s quote.
- What’s included: inspection, trapping, sealing, cleanup, follow-up.
- How the bill grows: per visit, per job or until you cancel.
- Your effort: what you still do yourself.
Pro prices: HomeAdvisor, This Old House and Orkin, checked against 100 rodent quotes homeowners posted on Reddit’s r/pestcontrol, r/homeowners and similar forums in 2024–2026, which we sorted by what the job included. DIY: U.S. list prices, September 30 and October 1, 2026.
Rat Exterminator Cost at a Glance
HomeAdvisor’s national rat figures (updated June 19, 2026):
| Part of the job | Typical pro cost | DIY cost |
|---|---|---|
| Inspection, billed on its own | $100–$200 | Free (a flashlight and an hour) |
| Trapping and removal, whole project | $189–$655 (average $395) | 6–12 rat snap traps, about $22–43 |
| Exclusion (sealing entry points), extra | $200–$600 | Copper mesh, about $29 |
| Cleanup of droppings and nests | Often part of the final visits; insulation replacement is priced separately | Gloves and bleach, about $15 |
| Follow-up or ongoing monitoring | $50–$150 per service | Checking traps each morning |
DIY column: the rat kit priced under All DIY below, about $65–87 in all.
What Homeowners Actually Get Quoted
Price guides understate the bill, because the job that works includes sealing. Here are the 100 rodent quotes homeowners shared on Reddit, sorted by what the pro offered to do:
| What the quote covered | Quotes | Median | Middle half |
|---|---|---|---|
| Traps or bait only, no sealing | 12 | $375 | $270–$500 |
| Trapping plus sealing (exclusion) | 53 | $2,000 | $1,400–$3,000 |
| Sealing plus attic or crawl space insulation replacement | 35 | $10,000 | $7,500–$14,000 |
Mouse and rat jobs came out almost the same: a $2,150 median for 31 mouse sealing jobs, $2,000 for 22 rat jobs. The top row is the price guides’ range, and it’s the one that rarely fixes anything; the bottom row is the upsell to watch for (one, two). For every pest, not just rodents, see what 5,315 real exterminator quotes show.
Ways to Pay for the Job at a Glance
| Option | Typical cost | Main limitation |
|---|---|---|
| Pro job with sealing | $1,400–$3,000 middle half, $2,000 median (53 shared quotes) | Insulation work is often pitched on top |
| Per visit | $75–$125 a visit | Rats often take several weeks of visits |
| Monthly or quarterly plan | Orkin: $249 on a plan up to $750+ one-time; monitoring $50–$150 per service | Keeps billing until you cancel |
| Pro inspection, then DIY | About $160–290 | You still do the trapping and sealing |
| All DIY | $57–71 mice, $65–87 rats | You handle every catch and climb every ladder |
One-Time Pro Job: Usually $1,400–$3,000 With Sealing
One price covers the whole project: inspection, sealing, trapping visits and a final check. HomeAdvisor’s $189–$655 rat range covers the trapping part; once sealing is in, the middle half of shared quotes is $1,400 to $3,000. Cleanup comes on the final visits; what an exterminator does walks through a visit.
Best for: rodents in ducts or other places you can’t safely reach.
Main limitation: expensive, and quotes often bundle attic insulation replacement at $7,500–$14,000; ask for that line separately.
Per Visit: Cheap Each Time, Not Overall
Some exterminators charge $75 to $125 a visit (This Old House). HomeAdvisor tells rat customers to plan on several weeks, with most homes rat-free after two to four follow-ups; paying doesn’t make rats leave faster than DIY trapping.
Best for: a small job where you want a pro to set and check traps.
Main limitation: the total depends on how many visits it takes.
Monthly or Quarterly Plan: Lower Per Visit, Bills Keep Coming
Orkin publishes a rodent control range of $249 to $750 or more. The low end is the price on a monthly plan, the high end a single one-time visit. Each monthly visit costs less, but the bills keep coming; ongoing monitoring is listed at $50 to $150 per service.
Best for: people who want someone else checking on a schedule.
Main limitation: no end date; get the yearly total in writing and ask what each visit includes.
Hire Only the Part You Can’t Do
HomeAdvisor suggests paying for an inspection and setting your own traps for a minor infestation. The inspector maps the gaps and how to seal each: a sealing to-do list.
| Approach | Rough total |
|---|---|
| All DIY | $57–71 mice, $65–87 rats |
| Pro inspection, then DIY | About $160–290 |
| DIY trapping, pro sealing | About $260–690 at price-guide rates; shared quotes often $1,000+ |
| Full pro job with sealing | $1,400–$3,000 |
The middle rows add the DIY kit to the inspection or sealing prices (our math). A common split: trap inside yourself, and pay for sealing at the roofline or anywhere you’d need a tall ladder.

Best for: a minor infestation with a few gaps out of reach.
Main limitation: you still check traps every morning.
All DIY: About $57–71 for Mice, $65–87 for Rats
| DIY item | Price |
|---|---|
| Wooden mouse snap traps, 2-pack | $2.29 |
| Wooden rat snap trap, each | $3.59 |
| Copper mesh for sealing, 20 ft roll | $28.80 |
| Nitrile gloves, 50 count | $8.49 |
| Bleach, 81 oz | $6.39 |
| Mice total, 12–24 traps | About $57–71 |
| Rats total, 6–12 traps | About $65–87 |
U.S. online list prices, checked September 30 and October 1, 2026, before tax and shipping; stores are under Sources.
Illustration: wooden mouse and rat snap traps, a roll of copper mesh, nitrile gloves and a jug of bleach.
Tonight, buy just traps (12 mouse traps $13.74; 6 rat traps $21.54), plus gloves and bleach. The copper mesh, the biggest item, can wait until you know where the gaps are. Nebraska Extension says two dozen well-placed snap traps are enough for a new mouse infestation in a 1,500-square-foot house.
The CDC recommends snap traps and advises against glue and live traps, which scare rodents into urinating and raise your risk of getting sick. UC IPM calls sealing the most permanent form of mouse control, and says ultrasonic devices and repellents haven’t solved rat problems for long.
Best for: most mouse problems and minor rat problems you can reach.
Main limitation: caulk, a caulk gun and a ladder aren’t included, and you handle every catch.
How Much Is a Mouse Exterminator?
Mice cost about the same as rats once sealing is included. This Old House (updated April 2026) puts a mouse job at $150 to $550, but the 31 mouse jobs with sealing that homeowners shared had a $2,150 median.
| Mouse job | Typical cost |
|---|---|
| Pro mouse visit, traps or bait only (This Old House) | $150–$550 |
| Pro mouse job with sealing, shared quotes (middle half) | $1,400–$3,000 |
| Pro charge per visit | $75–$125 |
| DIY: 12–24 mouse snap traps, copper mesh, gloves, bleach | About $57–71 |
Not sure which you have? Dropping size settles it, as our rat vs. mouse droppings comparison shows, and the mouse vs. rat guide covers the other clues.
Is My Exterminator Quote Too High?
A $1,200 rat quote is high for trapping alone but low for trapping plus sealing. The middle half of 53 shared trap-and-seal quotes runs $1,400 to $3,000, so a quote in that range is in line with what others were asked; above $3,000 it should come with a reason, such as a large or old house with many gaps. Insulation replacement is a separate job; the middle half of 35 shared quotes was $7,500 to $14,000.
A rodent pro on Reddit wrote: “Honestly, rodent jobs for me usually end up around $1500 and 3-4 weeks of monitoring.” One homeowner “called a company because I have one rat and they quoted me almost 20 K”; that estimate bundled removing all the attic insulation and replacing the crawl-space vapor barrier.
Step 1: Ask for it itemized. Trapping, sealing, cleanup and insulation each as their own line.
Step 2: Price the insulation separately. Ask to see the soiled areas; replacing insulation is a separate decision from getting rid of the rodents.
Step 3: Compare the rodent part with this page. Trapping and sealing far past $3,000? Ask why, and get a second quote.
Step 4: Ask what the guarantee covers. This Old House says many reputable companies offer free follow-up treatments or a refund if the rodents aren’t gone. Then get a second quote.
Which Option Fits Your Situation
| Situation | What to buy | Why |
|---|---|---|
| A few mice in the kitchen | All DIY, about $57–71 | Traps and sealing are the core of a pro job too. |
| Rats, but you can reach every gap | All DIY, about $65–87 | Same plan; see how to get rid of rats. |
| Gaps at the roofline | DIY trapping, pro sealing, $260 and up | Pay only for the tall-ladder work. |
| You can’t find how they get in | Pro inspection, then DIY, about $160–290 | The inspector gives you a sealing to-do list. |
| Rodents in ducts or a heavy infestation | One-time pro job | The CDC says call a professional for ducts. |
| You rent | Trap inside; tell the landlord in writing | Outside walls, vents and roof are the landlord’s building. |
What It Might Still Cost
The headline price is rarely the whole bill. HomeAdvisor says a bigger infestation needs more follow-up visits and fees rise past 10 traps; This Old House adds rural travel and city prices. Watch for these lines:
| Extra | Price |
|---|---|
| Inspection billed on its own | $100–$200 |
| Sealing entry points | $200–$600 in price guides; $1,400–$3,000 in shared quotes |
| Ongoing monitoring | $50–$150 per service |
| Live trapping and relocation | About $50 per rat |
| Emergency or after-hours service | $100–$200 extra |
| Insulation replacement | $7,500–$14,000 in shared quotes; ask to see the damage |
| DIY: caulk, caulk gun, ladder | — |

Before You Sign or Buy: A Quick Checklist
- Check the droppings to know whether you’re pricing rats or mice.
- Set snap traps tonight, before any quote arrives.
- Ask for an itemized quote: trapping, sealing, cleanup, insulation.
- Get the yearly total in writing for any monthly plan.
- Ask what the guarantee covers, and get a second quote.
- Tell your landlord in writing before anyone seals outside walls.
When Paying a Pro Is Worth It
Pay when you can’t safely do it yourself. The CDC says to call a professional for rodents in heating or cooling ducts, and heavy infestations call for a HEPA-filter respirator, because rodent diseases spread mainly through contaminated air. Ordinary droppings need just gloves and bleach mix (cleaning up droppings).
If 15 days of trapping and re-baiting doesn’t clear it up, consider professional help. Warning signs: pricing without an inspection, pressure to sign the same day, and bait stations with no sealing.
Common questions
Yes, for small holes. The CDC says to fill them with steel wool held in place with caulk or spray foam, but UC IPM notes steel wool pads may rust over time, which is why the kit prices copper mesh. More in steel wool vs. copper mesh.
Wear gloves, spray the rodent and trap with the bleach mix, and let it soak 5 minutes. Put both in a plastic bag, knot it, knot that inside a second bag, and throw it in a covered trash can. A rodent that dies out of reach is a different job, covered in finding a dead mouse by the smell.
The CDC recommends snap traps and saves poison or bait stations for infestations that persist. Poison baits can be dangerous for people and animals, so with kids, cats or dogs at home, follow the label exactly. Pro plans typically put them in tamper-resistant rat bait stations.
The Bottom Line
Start with under $25 in traps tonight and decide about a pro later. Pay only for what you can’t reach, like ducts and rooflines, get every quote itemized, and total any monthly plan before you sign.
