Soiled insulation, chewed fabric and cardboard are removed, and hard items are scrubbed and rinsed.

Mouse Droppings and Hantavirus Questions Answered in Castle Rock

How do I know if mice have been in my attic?

Common signs are small pellet droppings, shredded nesting material, grease marks along beams, gnaw marks and a musky smell. Scratching sounds at night can also point to rodents. A cleanup team can judge how much needs to be removed.

Who pays for rodent cleanup in a rental, the landlord or the tenant?

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.

Is it dangerous to clean up mouse droppings?

It can be if the droppings are dry and dusty. Sweeping or vacuuming can send fine particles into the air, where they are easy to breathe in. Wet cleaning with protection is safer, and larger jobs are best left to a cleanup team.

What should I do first if I find droppings?

Do not sweep, vacuum or blow them. Keep children and pets away, ventilate the space, and decide whether it is a small spot or a larger job. Call Castle Rock Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

What can be saved after a rodent infestation?

Hard surfaces and items in sealed plastic containers can usually be cleaned and kept. Insulation, cardboard and fabric soiled with droppings or urine are generally discarded. The crew sorts items with you before anything is thrown out.

Is it safe to stay in the house during rodent cleanup?

For small areas, usually yes, if the work zone is sealed off. For attics or heavy contamination, many owners prefer to stay away while the crew works. The team will explain what is best for your situation.
