  Rodents, Bats, Insects & Other vectors  

This program includes control of disease transmission from critters to humans. Of primary concern are bats, rats, certain insects, dogs, and cats. If you have concerns about disease transmission from a bat, rat, insect, or other animal, contact our office for further information.

Animal Bites

Pets are the most common cause of bites, with dog bites occurring most often. Cat bites may have a higher chance of infection (due to their longer, sharper teeth, which can produce deeper puncture wounds). Stray animals and wild animals, such as skunks, raccoons, and bats, also bite thousands of people each year.

Be sure your animals are current with rabies vaccinations. For additional information, see Animal Bites, National Institutes of Health MedlinePlus.

Avoid rabies risk by not handling bats and other wild animals. For additional information, see Bats and Rabies, National Center for Infectious Diseases.

Mice and Rats

Wild mice and rats can spread disease (hantavirus), destroy things in our homes and start fires by chewing electric wires. Find out how to avoid problems by keeping rodents out of your home and work environment. For more information, see Rodent Prevention [PDF].
