Completed project · Glendale, CA 91202 · May 2026
The job record marks rodent activity in this Glendale attic as severe, and the old yellowed batts showed it: crushed, torn and pulled apart around the pipes and ducts. Atticare USA removed the lot, cleaned and sanitized the deck, sealed the vents and chimney base with wire mesh and foam, and installed new R-38 16in batts.

The challenge
Severe rodent activity in crushed, torn batts
The before photos show old yellowed batts that had been flattened, torn and pushed around the duct runs, the pipes and the brick chimney. With severe rodent activity on the record, droppings and nests were through the old material.
Once the insulation was out, the deck underneath was heavily stained. That is why the full sequence mattered here: remove everything, clean and sanitize the deck, close the openings, and only then put new insulation down.


The service
What the crew did, in order
Prep and protection
Protective floor barriers and dust-barrier tunnels set through the work path before any material was moved, so the rest of the house stayed clean.
Remove the old insulation
The existing insulation taken out with a heavy-duty vacuum, down to a clear, bare surface.
Clean and sanitize
Heavy rodent waste, droppings and nests vacuumed out, then OdoBan sanitation applied to neutralize odors, pheromones and bacteria.
Seal and rodent-proof
Entry points closed with wire mesh, polyurethane foam and cement, with two to four indicator traps left as a check. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass.
New insulation
New R-38 16in Fiberglass Batts installed, on a clean, sealed surface rather than on top of the old layer.
The result
From severe contamination to a sealed attic and R-38
Protective floor barriers and dust-barrier tunnels went in through the work path first. The old insulation came out with a heavy-duty vacuum, the heavy rodent waste, droppings and nests were vacuumed out, OdoBan was applied, the service area was rodent-proofed with wire mesh, polyurethane foam and cement, with mesh and foam at the gable vents, framing openings and chimney base, and gaps around fixtures, piping, wiring and vents were air-sealed. New R-38 16in fiberglass batts went in last, with two to four indicator traps left as a check.

Questions homeowners ask
Attic work in Glendale, answered
Who cleans up an attic after heavy rodent activity in Glendale?
Atticare USA does. On this Glendale job, with severe rodent activity on the record, the old insulation came out with a heavy-duty vacuum, the droppings and nests were vacuumed out, and OdoBan was applied to neutralize odors, pheromones and bacteria before any sealing or new insulation. Where live animals are still present, a licensed pest control provider handles that part first.
Why does the old insulation have to come out after rodents, instead of adding more on top?
Because the contamination is in the old layer and on the deck under it. Here the deck was heavily stained once the batts were out, and it could only be cleaned and sanitized with the old material gone. Why the order of operations matters walks through it.
Does Atticare USA warranty its rodent proofing in Glendale?
Yes, for 1 year. On this job the gable vents, framing openings and the chimney base were sealed with wire mesh and foam, and two to four indicator traps were left as a check. Here’s how to compare rodent-proofing warranties.
