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.
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.
Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.
Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.
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 Squaw Valley Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
