You clean an attic after wildlife by first making sure every animal is out and every entry point is sealed, then removing the droppings, urine-soaked insulation and nesting material, sanitizing and deodorizing the wood and surfaces, and finally installing new insulation. Doing it in that order matters: cleaning before the house is sealed just gives the next animal a clean attic to move into. Because droppings from raccoons, bats and rodents can carry disease, it's a job for protective gear and the right equipment, not a shop vac and a dust mask. Silver Bullet Pest Control handles attic wildlife cleanup across North Jersey. Call 973-510-2585.
Even a few months of animals in the attic leaves damage you can see — and smell:
Raccoons use one spot as a toilet, so a raccoon attic usually has a heavy latrine that soaks into the insulation and the drywall below. The smell often reaches the rooms under it.
Squirrels scatter droppings and urine along their paths and nest close to the entry hole. Chewed wiring is a fire risk, so we check it during cleanup.
Bat guano crumbles into dust when disturbed, and rodents spread small droppings everywhere they travel. Both leave odors that attract the next animal.
Getting the animal out solves the noise. It doesn't solve what's left behind, and what's left behind is the part that affects your family.
Don't go up there with a broom. Sweeping or vacuuming droppings with a household vacuum throws contaminated dust into the air — and into your ducts if the HVAC is in the attic.
We inspect the roofline, soffits, fascia, ridge and gable vents, chimney, plumbing vents and where additions meet the old roof. Animals often use more than one hole.
Raccoons, squirrels and bats are removed or excluded with one-way doors so they leave and can't get back in. Mice and rats are trapped.
Heavy screening, metal flashing and hardware cloth that animals can't chew or pull apart — not foam or a piece of cardboard.
We make sure activity has stopped before the cleanup starts, so no animal gets trapped inside and no new mess shows up on clean insulation.
We set up a clear path from the attic access to the outside and cover floors and furniture along the way. The crew wears protective suits and respirators.
Soiled insulation, droppings, guano and nesting material come out with high-powered vacuum equipment and are bagged and hauled away.
Joists, rafters, sheathing and the top of the ceiling drywall are cleaned of what's left after the insulation comes out.
We treat the attic with disinfectant and odor control to deal with bacteria and the scent marks that draw animals back.
Chewed wires, torn ducts, damaged vents and stained wood are noted so you know what needs a repair or an electrician.
New insulation goes in to bring the attic back to a full, even layer. See attic insulation removal and replacement.
| What they leave | What cleanup usually involves | |
|---|---|---|
| Raccoons | Heavy latrines, urine-soaked insulation, torn ducts and vents | Removing the latrine area and the insulation around it, sanitizing, often replacing a large section of insulation |
| Squirrels | Nests near the eaves, scattered droppings, urine stains, chewed wires | Removing nests and soiled insulation along their paths, checking wiring, sanitizing |
| Bats | Guano piles under roosts, staining, strong ammonia smell | Careful guano removal with respirators, cleaning roost areas, odor control |
| Mice & rats | Droppings across the whole attic, tunnels and nests in insulation | Often full insulation removal, sanitizing, and sealing gaps lower in the house too |
| Dead animals | Strong odor, flies, fluids on insulation or drywall | Removing the carcass and affected material, then deodorizing |
An animal that died in a wall or attic is its own problem — see dead animal removal. Bats need special timing: responsible bat exclusion waits until the young can fly, so the cleanup is scheduled after the colony is out. Our bat exclusion comes with a 5-year warranty.
A handful of old mouse droppings in an otherwise clean attic is something many homeowners handle themselves: wear gloves and a properly fitted respirator, spray the droppings with disinfectant so they're wet, wipe them up with paper towels, bag everything and wash up well. Don't sweep or vacuum dry droppings.
It's time to call a professional when:
Pulling out loose insulation in a cramped attic, in summer heat, wearing a respirator, is hard and dirty work. A crew with the right vacuum equipment can usually do it far faster and with much less mess in the house.

Usually, at least in part. Insulation soaked with urine or full of droppings can't be cleaned in place, so the contaminated sections come out and new insulation goes in.
In most cases, yes. We work from the attic, keep the work area closed off and bag everything before carrying it out. We'll tell you ahead of time if a job calls for anything different.
It depends on the size of the attic and how much insulation has to come out. We look first and give you a timeline before any work starts.
Because a clean attic with an open hole is an invitation. Sealing first keeps new animals from moving in and soiling the new insulation.
They can be. Bat guano can carry the fungus that causes histoplasmosis, a lung infection that spreads when dry guano is disturbed and the dust is breathed in. Don't sweep or vacuum it yourself.
Remove the source — urine-soaked insulation, droppings and nesting material — then sanitize and deodorize the wood and surfaces. Air fresheners and sprays only cover it for a while.
Yes. We remove droppings and contaminated insulation, sanitize, and seal the gaps mice use so they don't come back.
It depends on your policy. Some cover damage caused by certain animals and some don't, so check with your insurance company. We can give you photos and notes from the job.
Yes. We remove or exclude raccoons, squirrels, bats, mice and rats and seal the house before cleanup begins.
Yes. We're licensed by the NJ Division of Fish and Wildlife and hold NJ Pesticide License 90568B.
