Type the gap length the bid will close, its rate, and the prices for trapping and clean-out. Traps without sealing bring the mice back. Never sweep or vacuum droppings.
Seal firstor the trap count starts overTrapping removes the mice already inside. Sealing stops the next ones. CDC says not to sweep or vacuum droppings, because that puts viruses into the air. HyrePest does not seal, trap or clean.
Rodent exclusion cost is the feet of gaps sealed times the quoted rate per foot, plus trapping and clean-out. With an example rate, 40 feet at $25 plus $150 trapping and $200 clean-out is $1,350, of which $1,000 is sealing. A total with no sealing buys the same problem again.
Sealing + traps + clean-out
Use the numbers from a written bid. Nothing is emailed. Never sweep droppings.
A budget from numbers you typed, not a quote. Seal first. Never sweep or vacuum droppings. HyrePest does not treat rodents.
How the rodent exclusion cost calculator works
The calculator adds three lines: sealing, trapping and clean-out.
sealing = linear feet × your $ per foot total = sealing + trapping + clean-out
If all three are zero, the tool asks for them. There is no national rodent average on this page.
Sealing is the line to look for. Traps and clean-out are real work, but they do not stop the next mouse. A total with sealing at $0 is a price for doing the same job again later.
Poison is not a line here, on purpose. We do not name or price a rodenticide. See rodent control for how the full job works.
What each input means
Input
What to type
Linear feet
The length of gaps the bid will close: vents, pipe and cable entries, garage door corners, the roofline. Not one hole. Leave it at 0 until the bid states it.
Rate
The $ per foot from that bid, with materials included if the bid says so.
Trapping
The price for trapping or monitoring the animals already inside. 0 if the bid is sealing only.
Clean-out
Droppings, nests and soiled insulation. In living space, hire a professional. Never dry-sweep to size this line.
Worked examples
The rates below are examples. Replace them with the numbers on your bid.
Sealing, traps and a clean-out
40 feet × $25 = $1,000 sealing, plus $150 trapping and $200 clean-out. The total is $1,350. Ask what material goes in each opening, and whether the garage door corners are included.
Traps and clean-out, no sealing
Feet 0, trapping $150, clean-out $200. The total is $350, with $0 sealing. If the dryer vent is still open, that $350 comes back. Add the sealing line before you call this the job.
The one where sweeping misleads
Someone sweeps the attic to “see how bad it is”, and the pile looks small in a dustpan. The cost is exposure, not dollars. CDC: “Don’t vacuum or sweep rodent urine, droppings, or nesting materials. This can cause tiny droplets containing viruses to get into the air.”
A quarter inch is the gap to seal
Most of pest control is judgment. This part is a measurement, and a federal health agency publishes it in one sentence.
The sentence. US Centers for Disease Control and Prevention: “Mice can fit through a hole the width of a pencil (1/4 inch or 6 millimeters in diameter).”
What that means. Every gap wider than a pencil is a door. Look where pipes and cables enter, at worn garage door seals, dryer vents, weep holes, soffits, rooflines and rusted crawl-space vents. A good survey finds them all and writes them down.
The materials. CDC names steel wool for small holes, secured with caulk or spray foam; lath screen or metal, cement, hardware cloth or metal sheeting for larger holes; and flashing around the base of the house.
Why sealing matters most. Metal, cement and mesh have no service schedule. A sprayed product fades, which is why it is sold by subscription. A well-sealed opening can last for years. That is our reading, not a CDC statement.
So look for the sealing line. A quote can look complete and still be made only of work that must be repeated.
Sealing, trapping and clean-out are three different purchases
Sealing, trapping and clean-out are often quoted as one lump called “rodent service”. The lump makes bids hard to compare and hides what you are buying.
Trapping removes the animals present. It runs alongside the sealing and ends when the traps stop catching. It changes nothing about the building.
Sealing stops the next ones. A quote with trapping and clean-out but no sealing is a service that has to be repeated.
This is not an accusation. Sealing an older house is slow, hard work. It can need ladders, sheet metal, and sometimes a roofer, carpenter or mason. A company may skip it because it cannot staff it. The difference is whether the quote says so.
Clean-out is the third thing. Soiled insulation, nests and droppings are a separate job with its own labor, protective gear and disposal.
Ask for three numbers. A bid split into sealing, trapping and clean-out can be compared line by line. A lump can only be compared to another lump.
The lines on a rodent quote, and what a missing one means
On this job, what is missing from a quote tells you more than what is on it.
Line
What a good quote states
What a missing line means
Sealing, by opening
A list of openings and the material for each. CDC names lath screen or metal, cement, hardware cloth, or metal sheeting for larger holes.
You are buying a service to repeat. The animals go, the building stays the same, and the problem can return.
Hard-to-reach openings
Which openings need a ladder, the roof, a crawl space or another trade.
The hard openings may be quietly left out. They are often the ones that matter most.
Trapping, with an end point
How many traps, where, and when someone returns to decide whether activity has stopped.
Trapping has no end, so it becomes a standing monthly charge.
Clean-out, priced separately
The soiled material, its removal and disposal, scoped by someone qualified.
A hazardous job was folded into general labor, or left out. Treat the quote as incomplete, not cheap.
Any rodenticide, named
The product and its EPA registration number.
You cannot read the label the applicator must follow.
License number and category
The state license and the category it covers.
You do not know whether the company is licensed for this work. Wildlife is often a separate license.
HyrePest does not seal, trap or clean. This table helps you read a quote someone else wrote.
Clean-out is a health job, not tidying up
Rodent droppings, urine and nests can carry disease. CDC’s first rule for cleaning them up is simple.
Do not sweep or vacuum. CDC: “Don’t vacuum or sweep rodent urine, droppings, or nesting materials. This can cause tiny droplets containing viruses to get into the air.”
Air the space out first. CDC: “Open all doors and windows for 30 minutes before cleaning to ventilate the space. Leave the area during this time.”
Protect your hands and wet it down. CDC: “Wear rubber or plastic gloves.” and “Spray urine and droppings with bleach solution or an EPA-registered disinfectant until very wet. Let it soak for 5 minutes or according to instructions on the disinfectant label.”
When to hire it out. Droppings in living space, a heavy infestation, or soiled attic insulation. Read CDC’s full cleaning guidance, and see our pesticide safety page.
Spread directly by rodents. CDC lists, among viral illnesses, Hantavirus, Hemorrhagic fever with renal syndrome, Lassa fever, Lymphocytic choriomeningitis (LCM); and among bacterial, Leptospirosis, Rat-bite fever, Salmonellosis, Sylvatic typhus, Tularemia.
Spread through ticks, mites and fleas. Plague, Lyme disease, Tick-borne relapsing fever; and Babesiosis and Cutaneous leishmaniasis.
What that list means. It is not a claim that any of these is in your attic. Several are rare or regional. It shows why soiled material is priced and handled as its own job. If you feel ill after rodent exposure, see a clinician and mention the rodents.
We publish no rat gap figure, and it changes nothing
A number you will see elsewhere is missing here on purpose.
What we could not confirm
CDC’s current page gives a gap size for mice only. The rat figures in circulation (dime, nickel, quarter, half-dollar) come from an archived CDC page and from university extension pages that disagree with each other. We therefore publish no rat number. Seal to the mouse standard and the rat question resolves itself.
Why it makes no difference
Whatever the rat figure is, it is bigger than a quarter inch. A house sealed against mice is sealed against rats too.
The test you can do yourself
If a pencil fits in the gap, seal it. You do not need a coin, a chart or a rat figure to decide.
Where our figure comes from
US Centers for Disease Control and Prevention’s rodent-control and seal-up pages give the mouse size and the materials. The rat number is on this site’s list of 7 claims we could not verify.
The order of steps EPA recommends
For rodents the order is easy to see: seal and clean up first, chemicals last.
EPA’s framing. “Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices.”
EPA frames prevention as a first line of pest control, describes preventive methods that present little to no risk to people or the environment, and treats chemical control as what follows when preventive measures have proved ineffective.
A caveat. The prevention examples on that EPA page are agricultural, such as crop rotation and resistant varieties. The hierarchy is EPA’s. Applying it to a house is HyrePest’s reading, and EPA’s consumer guidance below is the stronger source for a home.
The consumer rule. US Environmental Protection Agency: “If you hire any outside persons to help control pests, ask them to find and correct the source of the problem before applying pesticides.” For rodents, the source is a physical opening, so “find and fix the source” is literal.
On amounts and baits. “Always read and follow label directions. Using too much of a pesticide can endanger your family’s health.” EPA also recommends asking a hired professional to use baits and targeted treatments where feasible, and obtaining the EPA registration number and chemical information for your records.
Why chemicals go last here. A rodent that eats bait can die inside a wall, and then the wall has to be opened. That is our reasoning, not a regulator’s statement.
The label rule. A rodenticide is a registered pesticide. “It is a violation of Federal law to use this product in a manner inconsistent with its labeling.” Read more on integrated pest management.
What to ask before you accept a rodent quote
The first three questions separate a lasting job from a subscription. The rest check the risky parts.
Which openings did you find, and what will you seal each with?
You want a list, not just a total. A per-foot price with no list of openings means nobody has done the survey yet.
Is sealing in this price, or is this trapping only?
Trapping only is fine for an active problem. Just do not buy it thinking the house is fixed.
Which openings need another trade, and are they excluded?
Rooflines, soffits, crumbling masonry and rotten trim may need a roofer, mason or carpenter. A company that says so is being straight with you.
Is clean-out a separate line, and what does it include?
Ask about soiled insulation: removal, disposal and replacement. It can be a large number, and it is easy to leave out of a lump price.
When does trapping end, and who decides?
A review date turns trapping into a task with a finish, not a monthly charge.
If you use a rodenticide, what is it and what is its EPA number?
Ask where it goes, whether it is inside the house, and what happens if an animal dies in a wall.
What is your license number, and in which category?
Check it with the license lookup helper. Squirrels, raccoons and bats often need a separate wildlife license.
Do not accept a monthly plan instead of sealing
A monthly plan on a house with open gaps buys the same result over and over. Sealing is the line you buy once.
What this tool cannot do
Things the math on this page cannot see.
It cannot survey your house
The feet you type are a guess until someone walks the house looking for quarter-inch gaps. Many are high up, behind gutters or in a crawl space.
It cannot tell which animal you have
Mice, rats and wildlife are different problems with different laws. The pest identifier helps with droppings, but it is not a lab test.
It cannot price the clean-out well
Insulation removal depends on area, depth, access and disposal. Your number is a placeholder until a professional has seen the space.
It does not price other trades
Roof or trim repairs are separate quotes. A rodent bid with no line for them is the gap to watch.
It holds no price data
There is no national mouse-exclusion rate here. If you cannot name who priced the sealing, leave the rate at 0.
Words on a rodent quote
Exclusion
Sealing the ways in, to CDC’s quarter-inch standard for mice.
Trapping
Removing the animals already inside. It needs an end point and does not change the building.
Clean-out
Removing droppings, nests and soiled insulation. A health job, priced on its own.
Harborage
A sheltered spot near food and water: woodpiles against siding, stored cardboard, thick plants at the foundation.
Commensal rodent
A mouse or rat living in buildings. Squirrels, raccoons and bats are wildlife, often under different laws.
Rodenticide
A registered pesticide, so the label is the law. This page does not name or price one.
Questions this calculator answers
How much does rodent exclusion cost?
It costs what the sealing, trapping and clean-out lines add up to for your house. We publish no national average. The length of gaps, their height, the materials and access move a bid more than any published figure.
Should I just put out traps?
Not on their own. Traps remove the mice already inside. Sealing the gaps stops the next ones. Poison indoors can leave a dead animal inside a wall. CDC’s order is seal up, trap up, clean up.
How do I clean up rodent droppings?
Never sweep or vacuum them first. CDC says to air the space out for 30 minutes, wear rubber or plastic gloves, and spray droppings with bleach solution or an EPA-registered disinfectant until very wet before wiping up. Hire a professional for droppings in living space or a heavy infestation.
Is hantavirus a reason to panic?
No, but it is a reason to clean wet, not dry. Hantaviruses spread mainly from rodents, and stirring up droppings, urine or nests puts virus into the air. Avoiding contact with rodents and their waste is the best prevention.
How small a gap can a mouse use?
A quarter inch. CDC: “Mice can fit through a hole the width of a pencil (1/4 inch or 6 millimeters in diameter).” Pipe and cable entries, garage door corners, open vents and rooflines are the usual places to check.
Does the linear-feet line include the attic?
Only if the bid says so. Eaves, soffits and the roofline can be much of the footage, not the small gap you saw at the dryer vent. Type the footage on the proposal.
What about poison bait indoors?
This page does not recommend a rodenticide. Indoor poison can leave an animal dying inside a wall. If a product is used, the label is the law. Sealing and trapping first, then a labeled product used by a licensed applicator, is the professional order.
Do I need a clean-out if I only saw one mouse?
Maybe. Clean-out is for droppings and nests, especially in living space. If you find droppings in rooms you use, price a clean-out and follow CDC’s cleaning rules. Soiled attic insulation is a separate, bigger quote.
Is wildlife (squirrels, raccoons) the same tool?
No. Wildlife comes with different laws, different timing if young are in a nest, and different materials. This tool covers mice and rats. A wildlife job needs someone licensed for it in your state.
Does HyrePest remove rodents?
No. We do not inspect, seal, trap or clean, and matching is not live yet. Use the numbers from a licensed company’s written bid.
