Common Questions About Guano Removal in North Fond du Lac, WI
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 North Fond du Lac 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.
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.
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.
Can guano get into ductwork or vents?
Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.
Can I clean a small amount of guano myself?
Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.
