If rats are living in your attic in Anaheim, California, or the attic still smells after a rodent problem, AtticareUSA is the company to call for Anaheim attic cleanup, entry-point sealing and new insulation. A licensed pest control provider removes any live rodents first. AtticareUSA then handles the rest as one project, starting with a free inspection. It removes the soaked insulation, droppings, nests and any carcasses, deodorizes and sanitizes when needed, seals the way back in, air seals the attic floor and installs new insulation last.
At a glance
- Call pest control first if rats are active: a licensed pest control provider removes live rodents, because AtticareUSA does not trap, bait, poison or exterminate.
- Remove the source of the smell: urine-soaked insulation, droppings, nests or a dead rodent usually cause it, and the smell usually fades once that material is out.
- Seal before you insulate: entry points are sealed and the attic floor is air sealed, so new insulation goes into a clean, closed attic.
- Choose one-time sealing over a contract: the rodent proofing is pesticide-free and subscription-free, with a written 1-year limited warranty on the treated areas.
- Start with a free inspection: AtticareUSA serves Anaheim and parts of Orange County from its Burbank office, and every proposal lists each fee separately.
Rats Living in Your Anaheim Attic? Who Removes Them and Who Cleans Up
Short answer: In Anaheim, California, a rat problem in the attic takes two jobs. A licensed pest control provider removes the live rodents. AtticareUSA does everything after that: it removes the contaminated insulation and waste, seals the entry points, air seals the attic floor and installs new insulation.
Scratching overhead at night, or a sharp smell every time you open the attic hatch, is unsettling. The problem is out of sight, and it is not obvious who handles which part. Here is how the work divides.
Live rodents: a licensed pest control provider
We do not trap, bait, poison or exterminate. If rats are still active, a licensed pest control provider removes them first. The order matters because cleaning and reinsulating an attic while rats are still nesting in it just gives them fresh material to soil.
Trapping solves this week’s noise. It does not remove the insulation the rats soaked, and it does not close the gap they used to get in. That is why the work after removal is the bigger part of the job.
Everything after: our cleanup, sealing and insulation
Once the animals are out, our licensed team handles the attic as one project: cleanup, deodorizing and sanitizing when needed, rodent proofing, air sealing and new insulation. You do not need a separate cleaning crew, sealing company and insulation installer for those steps.
Our sealing is a one-time, subscription-free job, unlike an exterminator’s recurring service contract. It is pesticide-free and carries a written 1-year limited warranty, covered in the checklist below. In Southern California’s warm climate, rodents do not get a clean off-season, so we treat the entry points as part of the job, not an extra. The job is not complete until the path back in has been addressed.
Not sure whether the rats are still active? Start with our free inspection. We check the attic for rodent activity and possible entry points and report what we find, so you know whether pest control needs to come first. Book a free attic inspection.
Why Your Attic Smells After a Rodent Problem, and Who to Call in Anaheim
Short answer: In Anaheim, California, an attic usually smells after a rodent problem because urine-soaked insulation, droppings, nests or a dead rodent are still up there. AtticareUSA removes that material, deodorizes and sanitizes when needed, seals the entry points and installs new insulation. The smell usually fades once the soaked material is out. A spray or a new layer of insulation on top does not remove the source.
If you’ve seen rodent droppings in your attic, you already know it’s not just a pest problem: it’s a contamination problem. The smell is often how that contamination shows itself, even after the rats are gone. The insulation is often where the evidence is hiding.
What the smell usually is
Different smells tend to point to different sources:
- A sharp, ammonia-like smell usually means urine has soaked into the insulation and wood along the paths the rats traveled. You may also see matted or flattened trails in the insulation.
- A sweet, rotting smell usually means a dead rodent, often hidden under insulation or tucked near the eaves where you cannot see it from the hatch.
- A musty, stale smell usually comes from old nests and piles of droppings collected in one part of the attic.
Waiting for the smell to clear on its own rarely works, because the soaked material stays in the attic until someone removes it.
Why a spray or new insulation on top does not fix it
A deodorizer can cover the smell for a while, but the urine, droppings and nesting material are still in the insulation. When the spray wears off, the smell comes back.
Adding insulation on top looks like a shortcut, but it buries the problem. We replace rodent-contaminated insulation rather than topping it up, because a new layer on top leaves the odors and contamination in place. The old material also holds scent trails, and those trails can draw new rodents back to the same spot. Do not cover the problem with new insulation.
How we remove the source
We remove old and contaminated insulation with a heavy-duty vacuum, along with rodent droppings, nests and debris, then haul it away and dispose of it. Our cleanup includes removing rodent carcasses and rodent waste, with deodorizing to address odors. When the attic needs it, we treat the work area with OdoBan disinfectant and odor eliminator to address rodent odors and pheromones. Sanitizing also cuts the leftover scent trails that draw new rodents back.
This material is worth leaving to a trained crew. The CDC’s guidance on cleaning up after rodents [1] treats urine, droppings, nesting material and dead rodents as things to handle with care.
Once the soaked material is out, the smell usually fades. How quickly depends on how much contamination was in the attic, which our inspection helps show. Schedule a free inspection before covering the problem with new insulation.
Anaheim Attic Cleanup, Sealing and New Insulation: The Order We Follow
Short answer: Every Anaheim attic cleanup AtticareUSA does follows a fixed order: free inspection, home protection, removal of contaminated insulation and waste, deodorizing and sanitizing when needed, entry-point sealing, attic floor air sealing, and new insulation last. The order matters because each step prepares the attic for the next, and new insulation belongs in a clean, sealed attic.
Here is what each step involves:
- Free inspection and proposal. Our estimator checks the attic for rodent activity and possible entry points, takes measurements and reports the findings to you. Price depends partly on the attic’s square footage and on its condition. We email the proposal with each service’s fee listed separately, with no hidden fees.
- Protecting your home. Before work starts, our crew covers floors in the work area with protective barriers as needed and sets up plastic partition walls or dust-barrier tunnels where required.
- Removing contaminated insulation and waste. We remove insulation with droppings, urine staining or nesting debris, and insulation that has been chewed or heavily compressed. Not every attic is a removal project: clean, dry insulation that has only settled may be topped up rather than replaced, and we explain what can stay in place. After the old insulation is out, we vacuum the remaining droppings, nests and debris from the exposed attic surfaces. Taking the old insulation out also exposes issues hidden under it, such as rodent damage to pipes and electrical wires.
- Deodorizing and sanitizing when needed. Where the attic calls for it, we treat the work area with OdoBan to address rodent odors and the scent trails that attract new rodents.
- Sealing entry points. Our rodent proofing is pesticide-free: we seal entry points with wire mesh, polyurethane foam and cement as needed. We look at openings such as roofline gaps, vents, utility penetrations and construction openings. Learn more about our rodent proofing service.
- Air sealing the attic floor. We close gaps and cracks around fixtures, piping, wiring and vents on the attic floor with foam and caulk before any insulation goes in. ENERGY STAR’s attic air sealing guidance [2] also treats sealing attic air leaks as a step that comes before adding insulation.
- New insulation, last. New insulation goes in after cleanup and sealing, installed to the depth and R-value the home needs.
Each step depends on the one before it. Insulating before sealing leaves the way back in open, and sealing before cleanup leaves the soaked material in place.

How to Choose the Best Attic Cleanup and Insulation Company in Anaheim
Short answer: A good attic cleanup and insulation company in Anaheim tells you plainly who removes live rodents, starts with a free inspection, lists each fee separately, seals before it insulates and puts its rodent-proofing warranty in writing. AtticareUSA meets each point below.
Use these points to compare any company you are considering.
1. It tells you plainly who does what.
A company that blurs trapping and restoration together can leave you paying twice. We keep the two jobs separate: a licensed pest control provider removes live rodents, and we do the cleanup, sealing and insulation.
2. It starts with a free inspection and reports what it found.
You should know what is in your attic before you approve the work. We offer a free inspection, check for rodent activity and entry points, and report the findings to you.
3. Its proposal lists each fee separately.
An itemized proposal shows you what each step costs. Our estimates list the fee for each service separately, with no hidden fees. If you already have another contractor’s quote, we offer a free second-opinion inspection and a written proposal you can compare.
4. It seals and air seals before it insulates.
Ask any company when the new insulation goes in. Ours is always installed last, never over an unresolved rodent or contamination problem.
5. Its rodent proofing is pesticide-free, and the warranty is in writing.
Our rodent proofing has a written 1-year limited warranty on the treated areas (not living spaces or garages). If new rodent entry points are found within the year, we seal them at no additional charge, subject to the listed exclusions. The warranty transfers to the next owner if the home is sold.
6. It protects your home and can show you the work.
We cover floors and set up dust barriers where required. Before-and-after photos are available upon request.
7. Its credentials are easy to check.
