Most housing in St. Louis County is occupied, with a vacancy rate of about 7%, but sheds, garages and attics still go unvisited for months and can hold rodent buildup.

Crews check along walls, under appliances, in ductwork and across insulation, since rodents travel the same paths again and again.
A disinfectant solution is applied until droppings and nests are soaked, which keeps particles from becoming airborne.

Mouse droppings and urine can carry germs, including hantavirus in some wild rodents. They are not poisonous like a chemical, but breathing in dust or touching them without protection can make people sick.
Rodent droppings are treated as a contamination hazard because they can carry germs. In homes, the key risk is dust. In larger or older infestations, cleanup follows biohazard-style methods with protective gear and sealed disposal.
Buildings that sit closed for long periods can hold heavy rodent buildup, including nests and droppings that are dry and dusty. Crews ventilate first, wet down and use protective gear, since these are the settings tied to hantavirus exposure.
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.
Yes. Mice and rats can enter ductwork and leave droppings there, and the heating and cooling system can then move dust and odor through the house. Cleanup may include treating vents and duct openings.
Disinfectants can inactivate the virus, which is why droppings are soaked before they are wiped up. The method matters as much as the product. Follow label directions and never mix cleaners.
