What Is Rodent Exclusion? The Gaps We Seal, and Why Traps Alone Fall Short
Family-run, licensed and insured pest control in South Florida.
$50 OFF your first service + FREE inspectionNew customers · No code needed · No expirationWhat is rodent exclusion? It means sealing the gaps and openings rats and mice use to get into your home, so new ones can't follow the ones that get trapped. In South Florida that usually means the roofline and soffits, roof and gable vents, the spots where the AC line and plumbing go through the wall, and the corners of the garage door. Trapping without sealing tends to turn into a loop: catch two, hear more a month later. That's why we seal entry points ourselves as part of our rodent control, instead of handing you a list.
What is rodent exclusion, in plain terms?
Think of your house as having two jobs to do when rodents show up:
- Get out the ones that are already inside. That's trapping.
- Close the doors they used. That's exclusion.
Most of the frustration people have with rodents comes from doing only the first. Exclusion is the second half, and it's the half that keeps the problem from starting over.
Where rats and mice get into South Florida homes
These are the openings we look at on almost every inspection:
- The roofline and soffits. Torn or pushed-out soffit vents, gaps where the soffit meets the wall, and corners where two rooflines meet.
- Barrel tile eaves. The open ends of the first row of tile are a way in when the pieces that should close them are missing or broken.
- Roof and gable vents. Damaged screens, or vents that were never screened.
- Utility penetrations. Where the AC line set, electrical, cable and plumbing go through the wall. The gap around them often never got sealed, or the sealant cracked.
- The dryer vent. A flap that doesn't close all the way.
- Garage doors. The bottom corners, worn seals, and the gap at the sides.
- Doors and low gaps. Missing door sweeps, gaps around a pipe going into a slab, weep openings that got damaged.
A roof rat can squeeze through a gap about the size of a quarter, and sometimes smaller, so small openings count. Mice need even less. For the route roof rats take to reach those gaps, see our post on roof rats getting into the attic.
What a rodent exclusion visit involves
- Inspection. We look for activity, droppings, rub marks and the entry points, from the roofline down to the garage door. You'll hear what we found and where.
- Trapping what's inside. We set traps where the activity is, in places like the attic and the garage. Inside the home we use snap traps only, never loose bait. Tamper-resistant bait stations go outside.
- Sealing. We seal the gaps rodents are using with durable, rodent-resistant materials chosen for each opening. Foam or caulk by itself doesn't hold up against chewing, which is why it isn't used alone on a rodent gap.
- Follow-up visits. We come back to check and reset traps and stations, and we'll tell you how many visits your home is likely to need.
The order matters. Sealing every gap at once with rats still inside can trap them in the walls or attic. Trapping first, then sealing as the activity is handled, avoids that.
Some openings are really damage, like rotted fascia or a broken roof tile. We don't do repairs. We'll point the damage out so a roofer or carpenter can fix the wood or tile, and our exclusion work is sealing the gaps and entry points rodents use.
Why traps alone fall short
Rats leave scent trails, and the next ones follow the same route to the same gap. If the gap is still open, trapping just makes room for the next tenant. That's the "we caught them, and they're back" story we hear more than any other. If you're hearing them right now, our post on scratching in the ceiling at night helps you figure out what's up there.
Storms make it worse. Damaged soffits, loose tile and downed branches after a hurricane open new routes, which our page on rodents after a hurricane covers.
Can you do rodent exclusion yourself?
Some of it, yes. Here's a fair split:
| You can do this | Leave this to a technician |
|---|---|
| Have a tree service cut branches and palm fronds back from the roof (we don't trim trees) | Anything on a ladder at the roofline or soffits |
| Pick up fallen fruit and keep trash lidded | Barrel tile eave openings |
| Bring pet food in at night | Roof and gable vents |
| Add a door sweep to the garage entry door | Finding every gap, not just the obvious one |
| Keep woodpiles and storm debris off the walls | Deciding what to seal first while rodents are still inside |
The homeowner side matters a lot. It's the same sanitation advice we give on every rodent job, and it makes the sealing last longer.
Rodent exclusion cost in Florida: what changes the price
We don't publish a number, because two homes on the same street can be very different jobs. What moves the price:
- Size of the home and how much roofline there is.
- Roof type. A barrel tile roof with open eaves is a different job than a flat roof.
- Number and kind of openings. One gap at the AC line is not the same as a dozen soffit and vent openings.
- How many rodents are inside, which affects how many visits trapping takes.
Rodent work is quoted after the FREE inspection, once we've seen the house. Our rodent control page lays out the full approach, and our roof rat page covers the signs. Landlords can fold sealing into a turnover; see our between-tenants checklist.
After the rodents are out
Regular service keeps an eye on things. Our general pest plan is $125 per quarter, about $42 a month, and monthly or custom schedules are quoted after the inspection. For plan customers: "If pests come back between visits, so do we, at no extra cost." There are no long-term contracts and no cancellation fees, just a simple service agreement. We're family-run and licensed, with 30+ years in the business, and hablamos español. More reading in our guides.
