Animal remains removal and odor cleanup

What this involves

Rodents, squirrels, raccoons, opossums, birds and bats sometimes die inside a building: in a wall cavity, an attic, a chimney, a crawlspace or a duct. The first sign is usually odor, followed by flies, and sometimes a stain on a ceiling or wall. The smell can travel far from where the animal actually is, especially through ductwork and along joists, which is why people often open the wrong wall. Larger animals under a house or deck leave fluids in the soil and on framing that keep smelling after the remains are gone. Animals that die under a house or deck can also attract other wildlife, which may dig or tear at vents and screens trying to reach the remains.

Why professional remediation matters

Animal remains can carry bacteria and parasites, and the insects they attract spread contamination further. Some animals, such as bats and raccoons, carry specific disease risks; bats can carry rabies, and raccoon droppings near remains can carry roundworm eggs. Finding the source with as little demolition as possible takes patience and the right tools. Once the remains are out, the surrounding insulation, drywall or soil usually needs to be removed or treated, and the area disinfected, or the odor and flies will continue. Attics and crawlspaces bring their own safety concerns: heat, tight access, exposed wiring and nails, and insulation that should not be disturbed without respiratory protection.

What to avoid before help arrives

• Do not touch a dead animal with bare hands, and do not handle a dead bat. If anyone may have had contact with a bat, contact your doctor or health department.
• Do not cut multiple holes in walls trying to find odor; it often travels away from the source.
• Do not spray insecticide or fragrance into a wall cavity and seal it up. The source is still there.
• If an animal is still alive or injured, call a wildlife control operator rather than trying to remove it.

How the work is done

1. Locating. We trace odor, staining and insect activity to narrow down where the remains are, using the least invasive access we can.
2. Access. A small, planned opening is made where needed, or access is through an attic, crawlspace or duct.
3. Removal. Remains, nesting material and contaminated insulation or debris are removed and bagged.
4. Clean and disinfect. The surrounding area is cleaned and disinfected, and fluid-stained materials are removed or treated.
5. Odor and insects. Remaining odor is treated at the source, and fly or beetle activity is addressed.
6. Close-out. We show you where the animal was and point out entry gaps that a wildlife or pest professional should seal.

Waste handling

Small animal remains and contaminated debris are bagged and disposed of as solid waste in line with local rules. Larger animals may need a different disposal route, which we confirm for each job.

Afterward

Once the remains and contaminated materials are out, the opening can be patched. Unless the entry point is sealed by a wildlife control or pest professional, another animal may get in and the problem may repeat.
