About 63% of homes in Portland were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. With roughly 44 inches of annual rainfall in Portland, roof leaks and humid attics are common, and moisture makes droppings heavier and harder to remove.

Bird & Bat Guano Cleanup in Portland usually includes:

  • Sealing and bagging of contaminated waste for proper disposal
  • Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
  • Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
  • Odor removal and deodorizing of ammonia-like smells left by droppings
  • Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures

How Crews Contain and Remove Guano in Portland, OR

1. Find every deposit

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

2. Suppress the dust

Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.

3. Take out contaminated material

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

4. Disinfect and inspect

Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

Guano Cleanup Frequently Asked Questions in Portland, OR

Do I need to replace attic insulation after guano?

Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.

Who pays for guano cleanup in a rental?

It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.

Do barns and old buildings need special handling?

Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.

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.

What should I do first if I find guano?

Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Portland Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

Can you get sick from bat droppings?

Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.
