Histoplasmosis-Aware Guano Removal in Medina and King County

Histoplasmosis is a lung infection linked to a fungus that can grow in soil enriched by droppings from birds and bats. Guano cleanup is designed to keep those spores from being breathed in.

Guano is a respiratory risk, so your Medina property gets containment, wet methods and protective gear, then disinfecting and inspection before the space is handed back to you. For King County owners, call Medina Biohazard Cleanup Help.

Most housing in King County is occupied, with a vacancy rate of about 6%, but attics, chimneys and outbuildings can still go unchecked for years. Many homes in Medina, about 58%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell.

Bird & Bat Guano Cleanup in Medina usually includes:

  • Containment and wet removal of bat guano from attics, wall voids and rafters
  • Sealing and bagging of contaminated waste for proper disposal
  • HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
  • Removal of nests, feathers and carcasses left by birds or bats
  • Sorting, cleaning and sanitizing of stored items and belongings that can be saved

Guano Cleanup Frequently Asked Questions in Medina, WA

How do I know if I have bats in my attic?

Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.

Why shouldn't guano be swept or blown?

Dry droppings turn to fine dust that floats in the air and can carry fungal spores. Sweeping or blowing sends that dust into the air where you breathe it. Wetting first keeps particles on the surface.

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.

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 Medina Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

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.

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.
