Bats are often praised for their insect devouring abilities; however, studies of their diets often show very little preference for mosquitoes. While some smaller bat species hunt mosquitoes, most bats are going to prefer more substantial and larger insects like moths.
The bigger concern to human health regarding bats is rabies. Of the 239 confirmed rabid wild caught animals by the California Department of Public Health in 2022, 189 (78.4%) were bats. This makes them the most prevalent vector of rabies in the state.

NEVER TOUCH A BAT WITH YOUR BARE HANDS
Rabies is easily spread through an infected mammal’s saliva and caution must be taken when dealing with a bat. If you have a bat that has made it into the home, or you wake up to find a bat in your room, contact Santa Cruz County Animal Services and your physician immediately. Bat teeth are very small, and a bite may not be felt or noticed. DO NOT TRY TO REMOVE OR TOUCH THE BAT.
Santa Cruz County Mosquito & Vector Control can help residents inspect their home to prevent future bats from entering. Submit a Service Request for assistance with bat exclusion.
Pet owners should make sure their furry companions are vaccinated against rabies. California requires dogs that are over 4 months old to be vaccinated. Cats are not mandated to be vaccinated by state law, but it is highly recommended.
