While some bats hibernate, others travel to warmer climates. Bats may determine that your attic is the ideal location for a lengthy winter’s nap after bug activity starts to wane and they start searching for a spot to hibernate (or enter a condition of protracted torpor).
Bats normally start hibernating in October or November when the cold weather drives the insects away and come out of hibernation in March. Based on regional variances in seasonal temperature, bat hibernation habits can differ. Bats may be able to find food and remain active all year long in some areas of Florida and other southern states.
When do bats begin to hibernate?
Late autumn, towards the end of October or the beginning of November, is when bats begin their hibernating season. Before the start of springs in March or April, the dormancy can extend up to six months.
Although this is a typical period, torpor patterns in bats differ greatly between species and, occasionally, even within individuals. Although a period of hibernation is typically thought to last six months, there are frequently occurring arousals that can last up to twenty-four hours.
Bats lower their body temperature while hibernating, and since the immune system uses a lot of energy, it is one of the first to suffer. Bats must awaken and return to their higher body temperatures on a frequent basis to maintain their health during the six months when their immune systems are suppressed.
How do bats prepare for the winter?
Before the winter weather arrives, bats fill up on insects (they love beetles). After that, they will survive the winter on their fat stores.
These warm-blooded mammals will lower their body temperature from about 34°C to between 7°C and 10°C in order to preserve energy.
Then, in order to maintain the lower body temperature necessary for hibernation, they search for a cool, dry area to perch. Their heart rate drops to about 10 beats per minute and their metabolism drastically slows down.
Where do Bats Like to Hibernate?
One of their most dangerous times in life is during the six months they spend hibernating. They frequently lack energy, are hungry, and have a compromised immune system.
As a result, they usually choose the best location to spend the next six months before entering their torpor state. These locations, or hibernacula, might change from one year to the next.
However, they all need to offer the following features:
Although bats can regulate their body temperature to prevent freezing, they still need a certain range of temperatures to hibernate properly.
The recommended range for the estimate is 1 to 5 C. (35F to 40F). Any temperature below those indicated might cause bats to freeze since they typically maintain their internal temperature just 1 to 2 degrees Celsius above the ambient temperature. Meanwhile, hotter weather outside can force them to use excessive amounts of electricity.
Protection from the elements and predators — As we have seen, during the hibernating period, bats are most vulnerable. Predators and ailments like White-nose Syndrome can reduce their chances of surviving. So a bat will always seek out a hibernaculum that is sealed up, safe, and difficult to locate.
Direct contact to nature – Have you ever wondered how bats determine when it’s time to rouse themselves? Bats can sense the temperature difference and exit their refuge in the spring because the entrance to their hibernacula sucks in airflow from the outside.
Remember that bats are adaptable to urban environments. As a result, they are far more likely to choose a chimney, vent, or piece of siding as their hibernaculum than a cave. All these qualities may be found in our dwellings’ least populated or active regions, which is also near to their natural habitat.
Are bats active during hibernation?
Even while some bats may move about during their hibernating phase, most of them stay motionless because of how they self-preserve.
A bat’s metabolism slows down as it hibernates in order to save energy. The bat’s body enters and exits torpor on a daily basis, during which its heart rate drops from 200–300 beats per minute to as low as 10 beats per minute. This keeps the bat’s energy level constant.
It can survive for up to six months on a very tiny quantity of body fat saved thanks to el at 2% of regular life functions.
During hibernating, a bat may lose up to half of its body weight. Bats can adjust to their environment when they are in the torpor condition. In order to conserve energy, bats may reduce their body temperature from a usual range of 100 degrees or more all the way down to 40 degrees or less.
Bats Migration Patterns
Although bats may fly as fast as some birds, they cannot go great distances. Researchers have discovered that bats utilize the same natural signals to orient themselves as birds do, prepare for flight similarly, and employ airflow to travel greater distances based on earlier studies on the migratory habits of birds.
Even 200-mile flights are possible for certain bat species.
The fact that bats are nocturnal creatures accounts for why they travel further and slower than other birds. A bird may fly during the day and hunt for food at night, or the opposite may occur. A bat, meanwhile, completes all of its responsibilities at once. It must thus divide those hours between flying and gathering food.
Bats seem to favor migration over hibernation only if they roost close to warmer temperature zones because of the small amount of time and distance they may travel in a day.
Helping bats survive the winter
To love bats is to love the environment. In order to protect the survival of the bats they adore over the winter, the rangers at the Sherborne Park Estate take a variety of steps.
The rangers try to ensure that landscaping is done with this in mind because bats rely on echolocation to move around (listening to the echoes of their cries returning from adjacent objects). Hedgerows and field margins can be planted to aid with bat orientation and to draw in the insects that bats prefer to consume.
Problems Caused by Hibernating Bats in Winter
In order to prevent burning up their fat reserves throughout the winter, bats often move as little as possible. However, these pests may fly around the home looking for insects if they are startled by loud sounds, bright lights, or high temperatures. People who are hungry frequently pass away and eventually decompose in attics or hollow walls.
Accidentally discovering colonies may awaken the entire group, generating a frantic ruckus. Bats cuddle into insulation as a way of preserving body heat. Due to their actions, they could transmit the fleas, mites, ticks, and even bat bugs on their bodies throughout dwellings.
Signs of bats in your attic
It’s time to call in the experts if you believe a bat colony is residing in your house or if you just chance to see roosts in the tiny cracks of your attic walls when you’re up there. These roosts are usually located between the rafters or wedged between the roofing material and the rafters.
Even if there is no sign of a colony, use care since wild creatures might suddenly attack. Any bats that aren’t in hibernation will probably flee rather than interact with you.
Search for bat droppings and keep an ear out for any squeaking or scrambling noises (guano). Bat droppings are exclusively found in the areas under the roost, despite the fact that mouse droppings and bat droppings have a similar appearance (both are black, dry, and approximately the size of a grain of rice).
How do Bats Get Into Houses?
Although you may not realize it, bats are cunning little suckers.
Any space that is 3/8 inch or larger is breachable by bats. We’re discussing roof edges, loose tiles, vents, and chimneys. From a bat’s standpoint, the higher the better since homeowners will pay less attention to entry locations that are difficult to fix.
One thing to keep in mind is that bats do not munch their way through buildings. They will slip through once they detect a particular air current or temperature that suits them. They resemble flying ninjas, these guys!
They may unintentionally fly into an open window as well. The warm air attracts them even if they don’t want to enter your home, so make sure your windows are screen-free.
After you’ve taken care of the simple safety measures, it’s crucial to determine whether your home poses a high danger for uninvited guests.
How can I get rid of them?
Has your attic this winter evolved into a temporary bat roost? Given that illnesses may be conveyed by bat droppings, that condition is clearly not ideal. Fortunately, it’s much simpler than you may imagine to get rid of bats in Rochester, New Hampshire.
The most important thing to remember regarding bat removal is that you shouldn’t attempt to do it yourself; instead, you should always engage a qualified expert to handle those bats. We’ll first figure out how the bats entered your home and where exactly they have made camp before beginning the eradication process.
Next, each bat will be gently removed and moved. Then we’ll seal your attic to make sure you won’t soon see any bats there again.

What Houses are More Susceptible to Bat Colonization?
You are more likely to come across bats if you reside in a location with colder winters. The aim will be an ancient house with at least two stories. Bats will take advantage of the fact that you haven’t made any house repairs in a while if they can identify a flaw that will bring them inside.
In that manner, they are opportunistic.
Additionally, a whole bat colony can settle in if your attic is very big due to the abundance of accessible room. Bats like to nest in groups because they require one another to remain warm.
You should also consider the neighborhood around your residence. Bats are drawn to hollow, decaying trees. They also choose places with consistent water supplies, so if you live next to a lake, river, or pond, be ready.
What Species Of Bats Migrate?
The bat species that often move rather than hibernate are those that sleep outside or in trees. In heated chimneys and vents, bats that dwell in urban settings like cities prefer to spend the night. They won’t have any trouble settling in a sealed, ideal-conditioning hibernaculum when winter arrives.
Instead, it might be challenging to find a suitable hibernaculum in a natural setting that is both warm and protective. Although they may not provide much shelter from the outdoors, trees and caverns may not be warm enough for bats to comfortably hibernate.
In this situation, it is very possible that bats would migrate to warmer regions so they may dwell outside without feeling endangered.
Safety and Bat Control
Your home has to be secured against any unauthorized visitors if you want to keep it safe. Even though they may not have the most attractive appearances, bats desire a place to call their own. Nobody is trying to hurt you.
You’ll be more equipped to handle the problem and learn about methods to avoid it in the future if you have a better understanding of when and where they hibernate as well as how they might infiltrate your house.
Are bats attracted to your house? Learning about these animals is in your best interests. After being notified, you may take precautions to make sure they never really enter your home. Have a bat issue? Call us right away.
When Is Your House More At Risk?
The best method to handle a bat issue in your home is unquestionably to keep them out entirely.
While you might be able to live with one or two bats in an abandoned barn, a colony in your storage facility could pose a threat to your family’s health and safety. Understanding the rhythms of bat migration and hibernation will help you choose when to exercise the most caution so that you don’t experience unnecessary aggravation.
