Where Do Bats Go in the Winter: Understanding How Bats Hibernate
Table of Contents
When winter arrives, many winter pests begin searching for warm, sheltered places to survive the cold. This includes bats in winter, which often move closer to homes and buildings as temperatures drop. Attics, chimneys, and wall voids can provide the stable conditions bats seek during colder months.
As bats become less visible outdoors, many people wonder where bats go in winter. Some worry bats may be hiding inside their attic or chimney, while others are curious about how bats survive freezing temperatures. Because bat behavior changes significantly in winter, their absence can feel mysterious once cold weather sets in.
Bats survive winter by either hibernating or migrating. They choose the method that helps them save energy and stay protected from low temperatures. Some species remain in Missouri and enter a deep sleep in sheltered places. Other species move to warmer regions where food is available. Many bats in the U.S stay in temperate climates and enter a state called torpor to conserve energy during long, cold months.
This simple difference affects where they hide, how they behave, and why they may enter homes or buildings. It also helps explain why you might see signs of bats indoors even when it is cold outside.
Yes. Many species found in Missouri hibernate during winter. Hibernation is a state where their body slows down to save energy. Their heart rate drops. Their breathing becomes slower. Their body temperature lowers. This helps them survive months without eating insects. During hibernation, they stay still and quiet and only wake up if disturbed. Little brown bats and big brown bats are two common species of bats that hibernate inside caves and buildings because cool temperatures help them enter deep periods of torpor.
Bats look for safe, quiet spaces that stay steady in temperature. Outdoors, they use caves, mines, and deep rock crevices. Indoors, they may enter attics, chimneys, barns, and wall openings. They pick places that protect them from cold air and predators. Unfortunately, gaps in roofs, vents, and siding make homes a popular choice for them. Bats choose locations close to the ambient temperature because it helps them maintain fat reserves and survive without food.
Out in nature, bats choose areas that stay cool but not freezing. Caves are one of the best examples because they offer shelter from wind and hold steady temperatures. Mines, underground tunnels, and large rock formations also work well. In these areas, bats can group together, cling to walls, and stay safe for months. Hoary bats, little brown bats, long-eared bats, and silver-haired bats may use caves and mines as winter roosts or move into protected crevices to stay hidden.
These locations stay dark and quiet. These locations maintain moisture at safe levels that prevent dehydration, a key factor in how humidity attracts pests seeking stable environments. They also protect bats from sudden temperature swings. This makes them reliable winter homes year after year. Many bats have been found hibernating in caves or talus slopes, where bats hanging in clusters can remain undisturbed for weeks to months.
As natural roosts become disturbed or harder to find, bats often move into buildings. Attics, chimney gaps, and soffits provide warmth and steady conditions during winter. Many homes have small openings that people do not notice. Bats only need a gap as small as a half-inch to get inside. A winter bat may enter an attic when outdoor temperatures drop below levels needed to keep bodily functions stable.
A warm attic feels similar to a cave. Insulation provides comfort. Low activity means the colony feels safe. Once inside, they can stay hidden for months without detection.
If bats have entered your home, you may notice any of the following signs
Small piles of droppings near walls or insulation
A strong or unusual odor
Dark smudge marks near small openings
Sounds of faint scratching or light movement
A bat flying inside the living space
These signs often appear before you see a bat. Many people discover them during holiday decorating or when checking the attic for storage. If you have ever found a bat indoors during winter, it may be waking from torpor due to changes in indoor temperatures.
Bat droppings can create health hazards when left inside a home. When piles of droppings dry out, tiny particles can spread in the air. Breathing these particles can lead to respiratory problems. This is one reason why DIY cleanup can be unsafe.
Bats can also carry diseases such as rabies, though not all bats are infected. Only trained wildlife removal experts should handle or remove bats. Safe equipment, proper sanitizing steps, and protective gear are needed to clean affected areas. White-nose syndrome is a disease caused by a fungus that spreads among hibernating bats in caves and mines, and it has affected bat populations across the U.S.
Yes. Bats can wake up if disturbed by sound, movement, or changes in temperature. When a bat wakes up from hibernation, it uses a lot of stored energy. If this happens too often, the bat may not survive the winter. This is one reason why bat removal must be handled with care and proper timing. During brief periods of arousal, bats may fly out of a roost to return to normal body temperature, but this uses a lot of energy.
Some bat species migrate to warmer locations when winter arrives. They move to areas where insects are still active. These species do not hibernate in buildings as often because they follow their food sources. Even so, a few may stop in homes or other structures along the way. Bats migrate to places where flying insects remain available, often moving as far as northern Mexico during warmer months.
Migration usually occurs in large groups. These bats travel long distances and return to Missouri in the spring.
Many homeowners try to remove bats on their own and end up making the problem worse. Bats often hide deep inside walls or tight spaces. Scaring them out can spread them farther throughout the house. Blocking entry points at the wrong time can trap bats inside. This leads to dead bats in walls, strong odors, and structural damage.
DIY removal also exposes you to health risks. Bat droppings, nesting areas, and contact with wildlife require protective gear and specific cleaning methods. Bats must be handled carefully, especially hibernating bats that enter a state called torpor to conserve energy.
Our process is safe and humane. We focus on protecting your home and the bat population at the same time. Here is what we do
We look for signs of bat activity. This includes droppings, openings, and possible nesting areas. We identify how they got in and where they are hiding. We assess the roost site to determine which bat species are present, including little brown or big brown bats.
We install devices that let bats leave but not return. This method works with their natural behavior and avoids harm.
Once the bats exit, we seal gaps and repair damage. This stops future problems. Bats use small crevices and openings, so sealing each area prevents bats from entering again.
After removal, we clean affected areas and treat them to prevent odors and bacteria.
Bats enter through small gaps in
Roof edges
Chimneys
Vents
Soffits
Loose siding
Gable ends
Most openings are small enough to go unnoticed. Many bats enter through crevices that look harmless, and once inside, they stay as long as temperatures for hibernation remain stable.
Yes. Bats can cause damage to insulation, wiring, and attic materials. Their droppings can also lead to odors that seep through the home. Over time, the buildup can weaken structures or create health risks. Early detection helps reduce repair costs. Bats may cause water loss in insulation due to droppings and prolonged roosting.
If left alone, bats may stay inside a building for months or even years. They return to the same roost every winter. Without proper removal, the colony can grow larger each season. Some bat species can stay hidden in attics for weeks to months because they need cool temperatures for hibernation and enough insects during warmer months.
If bats are roosting inside the home, getting bats out of the attic requires a timed exclusion process that allows them to leave before every opening is sealed.
You can help reduce the chances of a bat problem by
Repairing damaged screens
Sealing cracks around rooflines
Adding chimney caps
Keeping vents covered
Scheduling yearly inspections
The following FAQ explains where bats go in winter and how hibernation works.
Most bats hibernate in protected places such as caves, tree cavities, abandoned buildings, or attics where temperatures stay stable.
Yes. Bats may hibernate in attics, walls, chimneys, or crawl spaces if the area provides warmth, darkness, and protection.
