Rodent exclusion: the quick answer

The short answer

Rodent exclusion means finding and sealing every gap rats and mice use to get in: about 1/4 inch for a mouse and 1/2 inch for a rat. Mississippi State University Extension’s standard is mortar, concrete, sheet metal or hardware cloth of 19 gauge or heavier with openings no larger than 1/4 inch. Foam or steel wool alone is a stopgap. Exclusion is the reason trapping works once and keeps working.

Why it matters

What rodent exclusion is, and why traps alone fail

Exclusion is the part of rodent control that makes the rest of it stick.

Trapping without sealing

Traps and bait remove the rodents inside your house today. The gap they came through stays open, so the next group moves in next week, and the one after that next month. This is how people end up paying for monthly service for a year with noises still in the ceiling. It is not that the traps failed. Nobody closed the door.

Sealing first, then trapping

Exclusion closes the doors first. Once every entry point is sealed with metal, the rodents still inside have nowhere new coming in to replace them. Trapping clears them out, the week test confirms it, and the job actually ends. One job, done right, instead of a subscription.

The inspection

Looking for someone who finds the entry points, not just bait stations?

Every rodent job we do starts here.

That exact question shows up again and again when people ask online for a rodent company. It is the right question. A gap you do not find is a gap you do not seal.

Our inspection goes from the roof to the dirt. We look at every place two materials meet, every pipe and wire that goes through a wall, and every vent. Each entry point gets a number, a photo and a note on how we will seal it.

You see the list before we touch anything. Nothing on it is vague, and nothing gets sealed that is not on it.

  • Roofline: soffits, fascia, roof returns, gable vents, plumbing vent boots
  • Trees and wires touching or overhanging the roof
  • Walls: AC line sets, cable, gas, water and dryer penetrations
  • Brick: weep holes, mortar gaps, cracks at the corners
  • Ground level: crawl vents, access doors, sill plate gaps, foundation cracks
  • Garage: door corners, bottom seal, wall-to-slab gaps
  • Inside: under sinks, behind appliances, attic hatch and chases

Entry points

The entry points rodents use most in Oxford, MS homes

Every house is different, but these ten show up on most of our inspection lists.

Entry pointWho uses itHow we seal it
Gaps around pipes and AC line setsMice and ratsCopper mesh packed tight, then sealed over
Roof returns and soffit gapsRoof rats, squirrelsSheet metal flashing cut to fit
Gable and attic ventsRoof rats19 gauge hardware cloth, 1/4 inch openings, fastened
Plumbing vent pipes on the roofRoof ratsGap at the boot closed with metal
Crawl space ventsNorway rats, miceHardware cloth fastened over the opening
Garage door corners and bottom sealMice, ratsRodent-resistant seal and corner guards
Dryer and exhaust ventsMiceMetal vent cover that still lets air and lint out
Weep holes in brickMiceWeep covers that keep the wall draining
Foundation cracks and sill gapsMice, Norway ratsMortar or concrete
Gaps under exterior doorsMiceDoor sweeps and thresholds

Why is the roof such a big deal here? Oxford is wooded, and roof rats use trees and power lines like a road system. On homes with oak limbs over the roof, the roofline usually holds more entry points than the foundation. Trimming limbs back from the roof is one of the cheapest things you can do to help.

Materials

Materials that stop rodents, and materials that don’t

The standard comes from Mississippi State University Extension and the CDC. Here is how common materials compare.

MaterialStops rodents?Where it belongs
Hardware cloth, 19 gauge, 1/4 inchYesVents, crawl openings, larger gaps
Sheet metal and flashingYesRoof returns, soffit gaps, chewed edges
Mortar and concreteYesFoundation cracks, masonry, around pipes in brick
Copper meshYes, packed tightGaps around pipes and lines; it does not rust
Steel wool with caulkShort termSmall holes only; it rusts out over time
Expanding foam aloneNoNever alone; rodents chew right through it
Plastic, window screen, woodNoRodents chew through all three

Does spray foam work? Not by itself. Foam is fine for insulation and as a finish over metal, but a rat goes through foam in a night. If a quote says “foam all gaps” and names no metal, ask what happens when they chew it.

Our process

How we seal a house, step by step

Sealing is careful, slow work. This is the order we do it in.

  1. Inspect and number

    Roof to foundation. Every entry point gets a number on your list.

  2. Photograph

    A before photo of every numbered point, so you can see exactly what was open.

  3. Seal with metal

    Hardware cloth, flashing, copper mesh, mortar, door sweeps. Materials named point by point.

  4. Trap and confirm

    Snap traps clear what is inside. The week test confirms the house is sealed tight.

After photos go in your report next to the before photos. You can check every point yourself.

Your kind of house

Older homes and newer builds need different work

The age of your house decides where most of the gaps are.

Older homes: Avent Acres cottages and historic Lamar houses

Oxford has a lot of older housing: 1950s cottages in Avent Acres, historic homes along North and South Lamar, and older houses on piers near the Square. These usually have crawl spaces, vents that have rusted through, mortar that has worn out and decades of settling. The work here is mostly low on the house: crawl vents, sill gaps, foundation cracks and old pipe penetrations.

Newer builds: utility lines, garage doors and wooded rooflines

About half of Oxford homes were built in 2000 or later. Newer does not mean sealed. The usual gaps are where AC lines, cable and gas enter the wall, at garage door corners, at roof returns, and anywhere a tree on a wooded lot reaches the roof. The January 2026 ice storm also left damaged soffits and vents on plenty of newer homes.

In writing

What a written exclusion plan should show

Customers who get burned by rodent companies almost always say the same thing afterward: they were never sure what was sealed, what was not, and who was responsible for what.

So we put it all on paper. You get this on every exclusion job, without asking for it. If another company quotes you, ask them for the same list. It is the easiest way to compare two quotes fairly.

  • A numbered list of every entry point found
  • A before and after photo of each point
  • The material used at each point
  • Who seals what, and who traps, if more than one trade is involved
  • Follow-up visit dates
  • What happens, and what it costs, if activity continues
  • The price, in writing, before work starts

Comparing quotes? Our quote checklist covers contracts, upsells and the questions worth asking.

Cost and timing

What exclusion costs, and when to schedule it

These are labeled benchmarks so you can judge any quote, including ours.

Job sizeTypical rangeWhat moves the price
A few entry points$200 to $600Height, roof access and material at each point
Whole-home exclusion$500 to $3,000+Number of points, crawl space condition, roofline length
Inspection$100 to $200Ask whether it applies toward the work
Trapping after sealing$250 to $300 to start, $50 to $150 per follow-upHow many rodents are already inside

Benchmarks come from 2026 national cost data and North Mississippi review data. Your exact price comes after we inspect, in writing, before anything starts.

When is the best time to seal a house in North Mississippi? Before the first frost, which averages about October 26 in Oxford. Late summer and early fall are ideal because you close the gaps before mice and rats start moving in. If rodents are already inside, the best time is now: sealing plus trapping in the same visit is still the fastest way to end it.

Straight answers

Rodent exclusion questions Oxford homeowners ask

Does spray foam keep rodents out?

Not by itself. Rodents chew through expanding foam quickly. It can be used as a finish over metal, but the barrier should be hardware cloth, sheet metal, copper mesh or mortar.

Do I still need traps after the house is sealed?

Yes, usually. Sealing keeps new rodents out, but any already inside are now sealed in with you. Traps clear them out, and the week test confirms the house is quiet.

Can I seal my house myself?

You can handle small, reachable gaps with copper mesh and door sweeps. The hard part is finding every gap, especially on the roofline, and working safely at height. Most failed DIY jobs missed one or two points, which is all a mouse needs.

Will sealing trap rodents in my walls?

That is why we trap at the same time and keep checking. Sealing without a trapping plan can leave rodents stuck inside, which is how you end up with a smell. Done together, the rodents inside are caught, not trapped in the walls.

How long does exclusion take?

Most Oxford homes take part of a day to a full day for the sealing itself, longer for big rooflines or crawl spaces that need a lot of work. Trapping and the week test take a couple of weeks after that.

Does exclusion help with squirrels too?

The same entry points at the roofline let in squirrels. Sealing roof returns, soffit gaps and gable vents with metal keeps both out. Squirrel situations may need a different plan for any animals already in the attic.

Will sealing hurt my home’s ventilation?

No. Vents get covered with 1/4 inch hardware cloth, which keeps air moving and rodents out. Dryer vents get metal covers designed to let lint and air pass.
