Bats are nocturnal, hibernate in winter and have their young in the spring. Residents who encounter a bat in their residence should never touch or remove it. Animal Control should be notified immediately to evaluate the situation and capture the animal.
Bats & Rabies
Bats are considered high-risk rabies vectors and by order of the state health department, any bat found in the living space of a residence should be captured and tested for rabies. These situations will be evaluated by Animal Control to determine if an actual rabies exposure has occurred.
Birds nest in leaves, vents, and attics and frequently fly down chimneys. The main complaint against them is the mess and smell caused by their droppings. Sparrows, starlings, and pigeons are common problems. Ammonia is not effective because birds have a poor sense of smell, so you'll have to screen off vents and other openings.
Migratory Bird Act
If a bird has nested in or on your house, deck, balcony, etc., do not disturb it. It is a federal crime and a violation of the Migratory Bird Act to remove songbird nests or babies. You must wait until the babies have flown away before you move the nest. (Courtesy of the Animal Welfare League of Arlington.)
