It is technically illegal to both 'rescue' and 'rehab' bats in the state of IL, due to the IL Dept of Public Health and their ill-willed stances that "most bat have the Rabies virus" and "the only good bat is a dead bat".
This is unfortunate for IL bats and IL citizens, especially in light of the spread of White-Nose Syndrome (WNS) to the Midwestern U.S. WNS has killed over 1 million insect-eating bats so far in the U.S.
Therefore, it is my opinion that every single one of our bats is important and truly makes a difference. Fortunately, Public Health Departments in 4 of IL's neighboring states (IA, IN, MO & WI) must have more sense than my state's lack of sense, as these states all have bat-friendly laws. Yes, it is actually perfectly legal to "help" bats in these states. Woo Hoo!!!
