Rat Control for Attics, Walls & Crawlspaces
Scratching in the attic, walls or ceilings at night? Hearing light scurrying or chewing inside the house? That’s the classic sound of rats or mice using your home as their highway—and your attic as their bathroom.
This page explains how rodent problems really work, why poison makes a bad situation worse, and how proper rat control is done: full-home inspection, sealing every entry point, trapping out the live population and protecting the structure long-term.
Signs You Have a Rat or Mouse Problem
Rodents are stealthy, but they’re not invisible. Once you know what to look and listen for, it’s usually clear when you’ve got rats or mice using your home.
- Scratching or light running sounds in ceilings, walls or attic at night.
- Chewing and gnawing noises as they work on wood, wires or plastic.
- Droppings in the attic, along walls, in cabinets or around the water heater.
- Grease marks and smudges along baseboards, beams and access areas.
- Chewed bags and food containers in pantries or garages.
- Bad odor in concentrated areas—sometimes from urine, sometimes from a dead rodent in a wall or void.
If the noises are mostly at night and sound light and fast—not heavy like a raccoon—rats or mice are usually at the top of the list.
Not Sure if It’s Rats, Mice or Something Else?
We narrow it down by:
- Noise pattern, timing and location in the home.
- Dropping size, shape and where they’re found.
- Chew marks and pathways along pipes, wires and framing.
- Exterior entry points and rub marks along the structure.

Rat & Mouse Damage and Health Risks
Rodents don’t just make noise—they quietly destroy things. They chew, nest and contaminate areas you rarely see until the damage is bad.
- Chewed electrical wires that can increase fire risk.
- Destroyed insulation used as nesting material and soaked with urine.
- Contaminated surfaces with droppings and urine in attics, walls and crawlspaces.
- Odor problems from heavy infestations or dead rodents in walls and voids.
- Food contamination in kitchens, pantries and garages.
Rodents breed fast. What starts as “a couple of rats” can turn into a full-blown infestation in a few months if the structure stays open and the food and water are easy to access.
How Rats and Mice Get Into Homes
Rats don’t teleport into your attic. They use very specific routes and access points, and once you know where those are, you know how to stop them.
- Roof rats: along fences, trees, utility lines and roof edges to get into attic and upper walls.
- Crawlspace access: through broken vents, gaps and plumbing openings under the home.
- Pipes and utility lines: gaps around AC lines, conduit, drains and water pipes.
- Garage and door gaps: under poorly sealed garage doors and side doors.
- Construction gaps: where different materials meet and weren’t sealed correctly.
A proper rodent job is really about finding every single hole they’re using—and closing them in a way that actually holds up.
Why Poison Doesn’t Fix Entry Points
Poison doesn’t seal a single hole. It just creates:
- Dead rats in walls, attics, ducts and crawlspaces.
- Odors and fly problems inside the home.
- Poisoned rodents that can affect pets or predators outside.
- No long-term solution—new rodents keep coming in through the same gaps.
Real rodent control is exclusion first, not “hope the poison gets them all.”
DIY Rat Control vs Reality
Hardware stores are full of traps, baits and foam. That doesn’t mean they’ll solve a real rat problem in a complex structure. In most cases, DIY ends up catching a few rodents— while the rest keep using the same entry points you never found.
Common DIY Rat Mistakes
- Using poison and ending up with dead rats in walls or ceilings.
- Foaming or caulking gaps rodents can chew through in a night.
- Trapping inside without sealing the outside, so new rats keep coming in.
- Setting too few traps in the wrong locations.
- Cleaning droppings without protection and spreading contamination.
Traps alone don’t “solve” rodent issues. Exclusion + trapping is the only combination that actually shuts a rat job down long-term.
Our Rat & Mouse Control Process
We treat rodent jobs like a construction problem and a population problem at the same time. If you only handle one side, the other side comes back to bite you—literally.
- 1. Full-home inspection: Roof, attic, exterior, crawlspace and garage are checked for activity and entry points.
- 2. Mapping the routes: We identify how rodents are traveling through and around the home.
- 3. Exclusion: We seal active and potential entry points with proper materials they can’t easily chew through.
- 4. Trapping: We use targeted trapping to remove the live population already inside.
- 5. Cleanup options: Depending on the infestation, we offer cleanup and sanitation for contaminated areas.
What You Get with Professional Rat Control
- A real explanation of how rats are getting in and moving through the house.
- Sealing and construction work that actually changes the structure.
- Poison-free, targeted trapping to remove rodents.
- Clear options for cleanup and prevention going forward.
The goal isn’t to sell you traps or monthly bait. The goal is to shut down rodent access to your home so you’re not dealing with this every year.

Rodent jobs aren’t one-size-fits-all. An early-stage problem with a couple of entry points is very different from a long-term infestation in a large attic and crawlspace.
- Inspection: Based on your area and how complex the structure is.
- Exclusion: Priced by how many gaps, vents and roof/ground-level entries need to be sealed.
- Trapping: Depends on the level of activity and number of follow-up visits.
- Cleanup & restoration: Based on how much contamination and insulation damage is present.
No Games, Just Reality
During the inspection, you’ll get:
- A clear picture of how bad the problem is.
- What needs to happen now vs what can wait.
- Options for doing it in phases if needed.
You’ll know exactly what you’re paying for and what it will actually change.
Rat & Mouse Control FAQ
Do you use poison for rats or mice?
No. Poison creates more problems than it solves: dead rats in walls and attics, bad odors, flies and repeat infestations because the home is still open. We focus on exclusion and trapping instead of poisoning your house.
Why do rats keep coming back after other companies treat?
Because most “treatments” focus on bait and traps and don’t solve the access problem. If holes, gaps and construction defects are not sealed properly, new rats simply replace the old ones. That’s why we focus on exclusion first.
Can I solve this with store-bought traps?
You might catch a few rats, but if the home is still open, you’re just treating symptoms. Most DIY setups don’t use enough traps, in the right places, or combined with proper sealing. It usually turns into a long, frustrating game instead of an actual solution.
How long does a typical rat job take?
That depends on activity levels and how many entry points there are. Many jobs involve an initial inspection and exclusion work, followed by a series of trap checks and follow-ups until we’re confident activity has stopped.
