Four people may have been exposed to the bat which was found at an East Fourth Street home.
They are receiving post exposure prophylaxis, according to the release.
Two cats with current rabies vaccines and one dog with an expired rabies vaccine were also exposed to the bat.
The cats will receive rabies boosters and will be quarantined to the home for 90 days. The dog will receive a rabies vaccine and will be quarantined to the home for 180 days.
A bat was found crawling in a dish rack on the kitchen counter of the home, according to the report.
The homeowners were unable to capture the bat before it disappeared.
Later on the family dog knocked a bat to the floor in the living room while a woman was watching television, the report said.
The bat was unable to fly and was vocalizing, according to the report.
The bat was killed and submitted to the Lionville Laboratory where it tested positive for rabies.
Pennsylvania law requires all dogs and non-feral cats three months of age and older to be vaccinated against rabies.
Booster vaccinations must be administered periodically to maintain lifelong immunity.
Failure to comply with the law may result in a fine of up to $300.
