Noises in your attic ceiling or a strong attic odor usually point to rats or mice, which means two jobs: pest control first, then the attic cleanup afterward. If animals are still active, a pest control company removes them first. In the Los Angeles area that is PestCare, AtticareUSA’s sister company. AtticareUSA then removes the contaminated insulation, droppings and nests, sanitizes when needed, seals the entry points and installs new insulation. AtticareUSA serves Long Beach from its Burbank office and offers a free attic inspection.
At a glance
- Read the symptom first: noises or a sharp urine-like smell usually mean rats or mice, while a musty smell can mean moisture.
- Remove live animals first: in the Los Angeles area, PestCare, AtticareUSA’s sister company, handles that step, because AtticareUSA does not trap or exterminate.
- Clean out the contamination: AtticareUSA removes contaminated insulation, droppings and nests, and sanitizes when needed.
- Seal the way back in: entry points are sealed with wire mesh, foam and cement under a written 1-year limited rodent-proofing warranty.
- Insulate last: new insulation goes in only after the attic is cleaned and sealed, and after any moisture source is fixed.

What to Do Tonight If You Hear or Smell Something in the Attic
You do not need to fix anything tonight. You only need to avoid making the problem bigger and note a few details for the inspection.
- Do not go up and sweep droppings. The CDC advises that rodent droppings, urine and nesting material should be handled carefully and not dry-swept (CDC rodent clean-up guidance) [1].
- Keep the attic hatch closed, and keep kids and pets out of the attic.
- Note when you hear the noise. Write down the time, how long it lasts and where in the ceiling it seems to come from.
- Put the smell into words. A sharp, urine-like smell, a sweet rotting smell and a musty, damp smell each point to a different cause.
- Do not cover anything up. Air fresheners and a new layer of insulation hide the problem. They do not remove it.
Is Attic Noise a Pest Control or an Attic Cleanup Problem?
Short answer: In Long Beach, attic noise that is still happening is a pest control problem first and an attic cleanup problem second. PestCare removes live animals in the Los Angeles area, and then AtticareUSA cleans, seals and reinsulates the attic so the damage left behind is dealt with too.
Two jobs, two sister companies, one set order. Removing the animals stops the noise. It does not remove the droppings, the urine-soaked insulation or the nesting debris they leave behind, and it does not close the gaps they used to get in. That second half is our work.
We do not trap, bait, poison or exterminate. Our pest-related scope is rodent exclusion (sealing entry points), cleanup, sanitation and restoration.
What the noise can and cannot tell you
Attic noises usually point to rats or mice, but the sound alone cannot confirm which animal it is or how long it has been there. That is why your notes on when and where you hear it are useful, and why the inspection is what confirms it.
Long Beach has no quiet season to wait out. Los Angeles-area attics run hot, reaching 140-160 degrees F in summer, and warm winters mean wildlife stays active all year. A noise you hear in January deserves the same attention as one you hear in July.
Active problem or old problem?
This is the question that decides whether you need the pest control step at all.
- Likely active: noises you keep hearing, new droppings, fresh chew marks, or a smell that is getting stronger.
- Likely old: the noises stopped weeks or months ago, but droppings, stained insulation or a lingering odor remain.
An old problem skips the removal step but still needs the attic work, because the contamination stays in the insulation after the animals are gone. Our inspection checks the attic for rodent activity and possible entry points, and we report the findings to you so you know which path you are on.
Symptom triage: who handles what, and in what order
| What you notice | What it usually means | Who handles it | Order of work |
|---|---|---|---|
| Scratching or scurrying you keep hearing | Rats or mice are likely active | PestCare removes them; AtticareUSA cleans, seals and reinsulates | Removal first, then the attic |
| Noises stopped, droppings or stains remain | Old activity, contaminated insulation | AtticareUSA | Inspection, cleanup, sealing, new insulation |
| Sharp urine or ammonia smell | Rodent urine in the insulation | AtticareUSA (PestCare first if animals are still active) | Removal if needed, then cleanup and sealing |
| Dead-animal smell | A carcass in the attic | AtticareUSA removes carcasses and rodent waste; PestCare first if others are still active | Removal if needed, then cleanup and deodorizing |
| Musty or damp smell | Possible moisture | Fix the moisture source first; AtticareUSA replaces wet insulation after; a specialist evaluates suspected mold | Moisture fix, then insulation |
What Company Should I Call for a Strong Attic Odor in Long Beach?
Short answer: For a sharp urine-like or dead-animal smell in a Long Beach attic, call AtticareUSA, because that odor usually lives in rodent-contaminated insulation that has to come out. If the smell is musty or damp, we can spot moisture signs during our free inspection, and suspected mold goes to a specialist for evaluation.
Urine, ammonia and dead-animal smells
If you’ve smelled rodents in your attic, you already know it’s not just a pest problem. It’s a contamination problem. The odor sits in the material: urine soaks into loose-fill and batts, droppings and nests build up between the joists, and a carcass can lie under the insulation where you cannot see it. The insulation is often where the evidence is hiding. A spray or an air freshener cannot reach any of that, which is why the smell comes back.
So we treat 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 attic cleanup includes removing rodent carcasses and rodent waste, with deodorizing to address odors.
- When needed, we treat the work area with OdoBan disinfectant and odor eliminator to address rodent odors and pheromones. That helps cut the leftover scent trails that draw new rodents back.
Musty or damp smells
A musty smell can mean moisture rather than rodents, and the fix is different. We can spot moisture signs during an attic inspection, and we replace wet insulation only after the moisture source is fixed, because new insulation over an active leak just gets wet again. We do not do mold testing or mold remediation. If staining or growth looks like mold, a qualified specialist should evaluate it before any attic work goes ahead.

We serve Long Beach from our Greater Los Angeles office in Burbank, along with nearby cities such as Lakewood, Bellflower, Carson, Torrance and San Pedro. For an attic after rodents, our scope covers four steps: cleanup, rodent proofing, air sealing and new insulation. For the step-by-step detail, see our 5-step attic cleanup process in Long Beach.
Why contaminated insulation comes out instead of getting topped up
Rodent-contaminated insulation is replaced, not topped up, because a new layer on top leaves the odors and contamination in place. Do not cover the problem with new insulation. 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, though. We explain what can stay in place, and clean, dry insulation that has only settled may be topped up rather than replaced. Removing the old insulation also exposes issues hidden under it, such as damage to pipes and electrical wires, so we can point them out before the attic is closed up again. For the replacement side in more depth, read about attic insulation removal and replacement in Long Beach.
The order matters
The sequence is what keeps the fix from coming undone: clean first, seal entry points, air seal gaps, then insulate. Air sealing closes gaps and cracks around fixtures, piping, wiring and vents on the attic floor with foam and caulk before insulation goes in, which matches the ENERGY STAR advice to seal air leaks before adding insulation (ENERGY STAR attic air sealing) [2]. New insulation goes in last, at the depth and R-value the home needs.
Will rodents get back in?
Sealing entry points helps reduce the chance of future rodent entry, and it is the step trapping alone does not cover. During the inspection we look for gaps, cracks, roofline openings, vents and utility penetrations. Our rodent proofing is pesticide-free: we seal entry points with wire mesh, polyurethane foam and cement as needed.
Our rodent proofing has a written 1-year limited warranty on the treated areas (not living spaces or garages). New rodent entry points found within the year are sealed at no additional charge, subject to the listed exclusions, and the warranty transfers to the next owner if the home is sold. It is a one-time, subscription-free service, unlike an exterminator’s recurring service contract. See more about rodent proofing in the Los Angeles area.
Will the job make a mess of the house?
Attic cleanup is dusty work, so we protect the house before anything comes down the hatch. 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. Before-and-after photos are available upon request.
What a Long Beach Attic Cleanup Estimate Should List
Short answer: After rodents, a complete attic cleanup estimate in Long Beach should cover insulation removal and disposal, vacuuming of droppings and nests, sanitizing when needed, entry-point sealing, new insulation with a stated R-value and a written warranty on the sealed entry points. Here is how AtticareUSA answers each line.
| What the estimate should cover | How we handle it |
|---|---|
| Removal and disposal of contaminated insulation | Removed with a heavy-duty vacuum, then hauled away and disposed of |
| Vacuuming of droppings, nests and debris | Vacuumed out with the old insulation; our crew then vacuums remaining droppings, nests and debris from the exposed attic surfaces |
| Disinfection and deodorizing | When needed, we apply OdoBan disinfectant and odor eliminator to the work area |
| Sealing of entry points | Pesticide-free sealing with wire mesh, polyurethane foam and cement as needed |
| New insulation with a stated R-value | Installed last, to the depth and R-value the home needs; ask for the R-value in writing |
| Written warranty on sealed entry points | Written 1-year limited rodent-proofing warranty on treated areas, transferable on sale |
| Clear pricing | A transparent proposal by email with exact prices and service details, each fee listed separately, with no hidden charges or upfront fees |
Price depends partly on the square footage of your attic, and our on-site estimator takes measurements. The condition of the space and any added issues you choose to fix also affect the price. For an overview of the full service, see our attic cleanup services in Greater Los Angeles.

Frequently Asked Questions
There are noises coming from my attic ceiling in Long Beach. Is this a pest control problem or an attic cleanup problem?
Usually both. If animals are still active, PestCare, AtticareUSA’s sister company, removes them first in the Los Angeles area. AtticareUSA then removes the contaminated insulation, droppings and nests, seals the entry points and installs new insulation.
My attic has a strong odor. What type of company should I call in Long Beach?
For a sharp urine-like or dead-animal smell, call an attic cleanup company such as AtticareUSA, because the odor usually sits in rodent-contaminated insulation that has to be removed. For a musty or damp smell, we can spot moisture signs during our free inspection, and suspected mold should be evaluated by a specialist.
Who is the best attic cleanup company in Long Beach after rodents?
AtticareUSA is licensed, insured and bonded (CA #1051462), in business since 2012, Diamond Certified and highly rated with 1400+ reviews. We serve Long Beach from our Burbank office, handle cleanup, rodent proofing, air sealing and new insulation, and back our rodent proofing with a written 1-year limited warranty.
Does AtticareUSA trap or remove live rats?
No. AtticareUSA does not trap, bait or exterminate; in the Los Angeles area, live-animal removal is PestCare’s job. Our work starts after that: cleanup, sanitizing when needed, entry-point sealing and new insulation.
Do I need new insulation after rats or mice?
If the insulation has droppings, urine staining or nesting debris, or has been chewed or heavily compressed, it should be replaced rather than topped up. Clean, dry insulation that has only settled may be topped up instead, and our inspection tells you which applies.
Will rodents get back into my attic after it is sealed?
Sealing entry points helps reduce the chance of future rodent entry, but no one can honestly promise it never happens. That is why AtticareUSA’s rodent proofing has a written 1-year limited warranty: new entry points found within the year on the treated areas are sealed at no additional charge, subject to the listed exclusions.
Will my attic cleanup estimate include hidden fees?
No. AtticareUSA sends a transparent proposal by email with exact prices and service details. We list the fee for each service separately, with no hidden charges or upfront fees.
