What should be done if a bat flies into a house and hides? - briefly
Open windows and doors, dim interior lights, and allow the bat to exit toward darkness; if it remains, wear thick gloves, carefully contain it, and either release it outside or call a licensed wildlife professional for assistance.
What should be done if a bat flies into a house and hides? - in detail
When a bat finds its way indoors and remains hidden, immediate, measured action is required.
First, keep the area quiet. Sudden noises and bright lights may cause the animal to become agitated and increase the risk of bites. Close doors to rooms that do not contain the bat, limiting its movement and reducing contact with occupants.
Second, identify possible exit routes. Open windows and exterior doors that lead directly outside. If a screen blocks the opening, remove it carefully. Position a flashlight at the opening to encourage the bat to move toward the light source.
Third, if the bat does not leave on its own, prepare for safe capture. Wear thick gloves, long sleeves, and eye protection. Place a sturdy container—such as a cardboard box or a plastic bin—over the animal, then slide a piece of cardboard underneath to trap it. Avoid handling the bat directly; its claws and teeth can cause injury.
Fourth, release the captured bat outdoors, preferably at night and away from lights, to increase its chances of navigating away from the house. If the bat appears injured, lethargic, or cannot fly, contact a licensed wildlife rehabilitator or local animal control agency for professional assistance.
Fifth, after the bat has exited or been removed, disinfect the area. Wear disposable gloves and clean surfaces with a solution of one part bleach to nine parts water. Dispose of any droppings, urine, or feather residue in a sealed bag. Allow the room to air out for several hours before resuming normal use.
Sixth, assess health risks. Bats can carry rabies; any bite or scratch requires immediate medical evaluation. Even without direct contact, inhalation of aerosolized particles from droppings may cause respiratory irritation. Keep children and pets away from the treated area until cleaning is complete.
Finally, implement preventive measures. Ensure all exterior entry points—chimneys, vent pipes, attic gaps, and eaves—are sealed with mesh or weather stripping. Install bat house structures away from the home to provide alternative roosting sites, reducing the likelihood of future indoor incursions.
