Cleaning Up After Bats and Birds in Ontario, OR

Bird droppings cleanup covers pigeon, starling and sparrow droppings on roofs, ledges, balconies, rafters and rooftops. Dry droppings can turn to fine dust, so they are wetted before they are scraped and bagged.

Found guano in a hard or unsafe place to reach in Ontario? People in Malheur County call Ontario Biohazard Cleanup Help and get a cleanup team that works discreetly, explains each step and sorts what you can keep from what must be discarded.

With a vacancy rate of 12% in Malheur County, unused structures often hold years of droppings by the time someone opens them up. Ontario is on the drier side, with about 10 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal.

A typical bird & bat guano cleanup job includes:

Documentation of the work for buyers, inspectors, landlords and insurers
Cleaning of stained ceilings, walls and floors below an affected attic
Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
HEPA-filtered vacuuming and air cleaning to capture fine dust after removal

The Bat and Bird Droppings Removal Process in Ontario

1. Find every deposit

Crews check roost sites, rafters, ledges and insulation, since droppings build up where animals return again and again.

2. Set up protection

Barriers and air controls go up, and the team wears protective gear before touching anything.

3. Take out contaminated material

Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.

4. Final walkthrough

Odor and air are checked, and the owner is shown what was done and what remains for other trades.

What Ontario Property Owners Ask About Guano and Histoplasmosis

How do I get rid of the guano smell?

The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.

Does guano cleanup stop bats or birds from coming back?

No. Cleanup removes the mess but does not block entry points. A wildlife professional can seal gaps and use deterrents. Removing droppings and odor does help, since scent can draw animals back.

Does guano damage insulation?

Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.

Should I remove the bats first or clean the guano first?

The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.

Will the smell go away after cleanup?

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.

Is it safe to stay home during guano cleanup?

For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.
