As the weather gets colder in Ohio, bats begin preparing to transition from warm to freezing temperatures, which means Ohio bat hibernation. Most Ohio bats flee the winter weather by migrating south, but others hold out until the warm weather returns by hibernating in caves or buildings.

When Ohio bats hibernate, they enter a state called torpor. Bat torpor is an involuntary state that involves low heart rate, body temperature, and metabolic rate. Throughout winter, bats slowly metabolize their fat stores until they can search for food in the spring. But this year, Ohio bat hibernation could be very different.

Ohio Bat Hibernation on the increase in 2021-22

Several different bats are typical in Ohio. Two of the most common bats are the Big Brown Bat and the Little Brown Bat.

Ohio’s Warmer Autumn Means More Ohio Bat Hibernation

This year Ohio’s autumn temperatures have been higher than average. Bats get confused by the extended warm weather and stay longer than usual, and if they remain too long, they often won’t head south. So due to the warm weather extending later in the year, Ohio Bat Hibernation, in all probability, will increase in Ohio, and many more bats will not head south to hibernate.

As a result of not leaving for the south, bats in different phases of stress due to a quick change to cold weather will show up in yards, parks, and driveways, searching for a safe Ohio Bat Hibernation space. Some bats will be attached to outside structures while others tuck into corners of windows, eaves, and sills seeking shelter.

During extended periods of warm weather in autumn bats can get discombobulated and miss their opportunity to fly south for warmer weather.

An Ohio Bat Hibernation In Your Attic Means Guano And Urine

Homeowners will need to be especially aware that their attics may be an Ohio Bat Hibernation sanctuary for a colony of bats choosing not to migrate south. If bats wake up in a homeowner’s attic in the middle of winter due to unusual weather warming, their metabolic systems may return to normal. If this awakening occurs, bats feel the need for food to feed their lost fat stores. However, locating insect food to sustain them in the winter is highly unlikely when their Ohio Bat Hibernation gets interrupted.

If bats have taken up residence in a home’s attic during this winter awakening from their Ohio Bat Hibernation generally, they will not be able to find insect food. This awakening of bats often results in them not returning to hibernation and may die as a result. During this time, many homeowners may hear sounds like scratching, squeaking or flapping in their attics.

Expect more Ohio Bat Hibernation in your homes and buildings this winter

Do not be surprised if you find a colony of Big Brown Bats hibernating in your Ohio attic this winter. At the end of the Ohio Bat Hibernation season expect to find plenty of bat guano in your attic if it housed a colony of bats.

You’ll Need A Wildlife Control Team To Cleanup After An Winter Attic Infestation

Ohio attics provide ideal shelter for bats, especially the Big Brown Bat, that do not fly south for the winter. Concealed in attics, huddled between walls, and snuggled into other corners and crevices, bats can survive the winter without utilizing precious energy.

Bats need particular temperatures for hibernation varying between 35 to 40 degrees. If Ohio’s Big Brown bats uncover these “temperature-controlled” locations, they provide the maximal possibility for their survival. Artificial areas, as opposed to caves, like Ohio homes with attics, provide perfect hibernation opportunities.

Once in an attic, bats will often congregate under insulation to get close to the warmest side of a wall or ceiling. Fortunately for you, bats do not poop during hibernation. But if bats are hibernating in your attic, and some odd warm days pop up, do not be surprised if you find a bat escaping into your living quarters.
