Yes, absolutely. Due to the high public health risks, home buyers may demand a full bio-remediation if bats are found.   Bio-remediation typically entails removing/replacing all contaminated materials (drywall, insulation, etc).  This results in a major remodel project costing 10’s or 100’s of thousands of dollars.   As a seller, you are required to disclose any known infestation or contamination and may be sued if you do not disclose these issues.  The best solution is prevention.
