Completed project · Glendora, CA 91741 · July 2026
Severe rodent activity had left the old batts in this Glendora attic matted, stained and soiled with droppings. Atticare USA vacuumed all of it out, cleaned droppings and nests off the hard surfaces, sanitized the whole work area with OdoBan, sealed every potential entry point, and replaced the air ducts to code at their existing diameters.

The challenge
Old batts fouled by severe rodent activity
The record puts rodent activity at severe. Photos show the old white batts crushed and pulled out of place between the framing, with dark staining and droppings through them.
Vent openings through the attic walls also needed closing off. Cleaning the attic without sealing those routes would have left the way in open, so the job covered cleanup and rodent proofing together.



The service
What the crew did, in order
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.
Air duct replacement
Air ducts removed and replaced to code, matching the existing diameters.
The result
A cleaned, sanitized attic with its entry points closed
All existing insulation came out with a heavy-duty vacuum. Rodent droppings, nests and debris were vacuumed from the hard surfaces, and OdoBan was applied across the full work area to neutralize odors, pheromones and bacteria. Entry points across the service area were sealed with wire mesh, polyurethane foam and cement, with indicator traps left as a check, and the air ducts were removed and replaced to code, matching the existing diameters.
