Leptospirosis is spread by their urine, which causes damage to the kidneys and liver. It can also be caused by inhalation or physical contact with scat. Cardiovascular problems and liver failure are complications of the disease. Lymphocytic choriomeningitis can be spread in the same manner. Allergic reactions to rat and mouse dander are typical.
Squirrels are a frequent pest and often tear apart the building structure. They are known to carry ticks into homes and many have the Borrelia bacteria which causes Lyme disease and these ticks often end up on pets. Squirrel urine and droppings can risk salmonella and leptospirosis — a bacterial infection that mimics the flu and serious cases can cause internal bleeding and organ failure.
Families of raccoons are easy to find as well. Many raccoons carry Baylisascaris, a type of roundworm. They pass in feces and eggs can be transferred with human contact. Once the eggs hatch, symptoms may include drowsiness, dizziness, blindness, loss of muscle control, and coma. Raccoons can also carry rabies, which is fatal to most people if contracted.
Taking quick action to remove these pests immediately is important to ensure the health and safety of every person in the home.
