What animal waste cleanup involves
Animal waste cleanup is the removal of droppings, urine, nesting material, contaminated insulation and, sometimes, carcasses left by rodents, birds, bats, raccoons, opossums or pets. It usually happens after the animals have been removed or kept out, and it is the part of the problem that pest control and wildlife companies typically do not handle.
The hazard is often in the material itself. Dried droppings and nesting debris can release dust when disturbed, urine soaks into insulation and wood, and the odor can travel through a home long after the animals leave.
Because the work often happens in tight attics and crawlspaces, it also takes planning: safe footing on joists, lighting, protection for the rooms below and a way to carry bagged material out without tracking it through the house.
Different animals, different concerns
Each animal brings its own pattern. Mice and rats scatter droppings and urine along runways and nest in insulation. Pigeons and other birds pile droppings in layers below favorite perches. Bats leave guano heaped beneath a roost. Raccoons use a single latrine site repeatedly. Pets tend to soak one area of flooring over and over.
Those patterns decide the method. A rodent attic calls for wet removal and insulation work, a pigeon roost for dust control at height, and a pet-soaked room for flooring removal and subfloor treatment. We match the approach to what we find rather than applying one routine everywhere.
Signs you may need this service
- Droppings along baseboards, in cabinets or across attic insulation
- Shredded insulation, paper or fabric used as nesting material
- Staining or a musky, ammonia-like odor in ceilings or walls
- Piles of droppings on attic floors, ledges or rooftop equipment
- A concentrated toilet area on a deck, roof or in an attic
- A persistent odor of decay with flies gathering in one spot
Removal comes before cleanup
We do not trap, relocate, exclude or kill animals. In Tennessee, any business that applies pesticides for compensation, including rodenticides, needs a pest control charter from the Department of Agriculture, and wildlife removal and exclusion are handled by wildlife control professionals. Some species, including certain bats and birds, may be protected, which is another reason that step belongs with specialists.
Ideally, the pest or wildlife company finishes its work and seals entry points first. Cleaning before exclusion often means the job has to be repeated when animals return.
How we clean up after animals
- Inspect and confirm We look at the affected areas, confirm the animals are gone or excluded, and note what materials are contaminated.
- Ventilate and contain We air out the space where possible and use plastic sheeting and negative air to keep dust from spreading into living areas.
- Wet, then remove Droppings and nesting material are dampened with disinfectant and allowed to soak before removal, rather than swept or dry-vacuumed.
- Remove contaminated insulation Heavily soiled insulation is removed with HEPA-filtered equipment and bagged for disposal.
- Clean and disinfect Exposed framing, floors and surfaces are cleaned and then disinfected with EPA-registered products used per label.
- Address odor and document Remaining odor sources are found and removed, and you receive photos of the finished work.
Health guidance we follow
For rodents, CDC advises ventilating the space before cleanup, not sweeping or vacuuming droppings or nests, and wetting them with an EPA-registered disinfectant or a bleach solution before wiping them up. The reason is hantavirus, which CDC says can become airborne when fresh droppings, urine or nests are disturbed.
For bird and bat droppings, NIOSH explains that the fungus that causes histoplasmosis grows in soil enriched with droppings and that infection comes from breathing in spores. NIOSH recommends reducing dust, for example with a water spray, and using a NIOSH-approved respirator, coveralls, eye protection, gloves and shoe covers.
For raccoons, CDC notes that roundworm eggs in their feces become infectious after a few weeks and that human infection, while rare, can be severe. We follow these precautions and use respirators under a respiratory protection approach. We do not test for or promise to eliminate any specific organism.
Where we work
Most of our animal waste work happens in attics, crawlspaces, wall cavities, garages, sheds and basements. We also clean living areas after pet accidents, including soaked carpet and subfloors, commercial rooftops and ledges with pigeon droppings, and church steeples, barns and outbuildings where bats or birds have roosted.
Homeowners, landlords with rental units, property managers, owners of commercial buildings, churches, schools, restaurants and warehouses all call us. We serve all 41 counties of Middle Tennessee from the Nashville area.
For businesses, we can schedule around operating hours and provide photos for facility records. In homes, we protect finished rooms below an attic with drop cloths and containment and keep the work as tidy as possible.
Trapping, exclusion and repairs
- Trapping, baiting, exclusion and wildlife removal go to pest control and wildlife professionals.
- Duct cleaning and HVAC repairs go to HVAC contractors.
- Chewed wiring goes to an electrician.
- Roof, soffit and structural repairs go to qualified contractors.
- Questions about possible illness go to a healthcare provider.
Planning, cost and insurance
We explain the scope before work starts, including how much insulation or material needs to come out and whether replacement insulation is something we handle or something a contractor should install. Property insurance often treats animal damage as an exclusion or a limited coverage, so check your policy and talk with your agent.
