5 Essential Steps on How to Get Rid of Bats
That's not a great secret that today there are many different insect and wildlife control problems. Problems aren't necessary if they don't bother you and your family, but what if bats are right in your house? Tackling them alone can be an excellent way out if you know how things should be done.
I've decided to provide all the necessary information and helpful tips on eliminating these creatures from your home. So, I've managed to select the alternatives that:
- don't damage the property,
- never harm the animals,
- are safe for people and pets.
Let's see what can be done.
Step 1. How Do You Know If You Have Bats In Your Attic?
I have a bat in my attic. This statement is severe. Are you sure about that? Before making haste decisions, you'd better look for signs of infestation:
- Droppings. The feces carry a fungus that causes Cryptocacaous and Histoplasmosis. If you have noticed any animal exists in or around your house. Avoid direct contact with the droppings, and don't inhale the air.
- Bugs. Bat roosts harbor parasites like bat bugs that move into the houses and can be confused with bed bugs. Besides, they can bite and transmit diseases.
- Odor. The urine of the creatures emits a strong odor that soon lingers inside your place.
- Stains. They leave grease marks around the living area.
Step 2. Identification of the Entry Points
Locating entry points are called to be the best way to get rid of multiple bats fast. Place them from the outside of your house, as well as they were inside the attic.
Inspection allows a homeowner to find the entries and prevent further infestation.
As a rule, this can be done by getting on the roof. For this purpose, you should get a high ladder to reach the highest points. While inspecting, you will identify the entries marked by the bats' dirty stains, marks, and droppings. Remember that the size of the holes can be ½″ high, 1½″ wide. Through holes are pretty small. Even giant bats can squeeze through them.
At times they are left unnoticed. That's why paying particular attention to any stains can be helpful.
How Do Bats Find the Way to Get in the House?
They usually enter the building in an opening or crack as small as 3/8 inch. This is why it is pretty easy to miss such tiny entry points.
If there are holes in walls, around the chimney, loose boards, or cracks underneath the eaves, you can suffer from bat infestation.
Additional ways they gain entries include:
- unscreened direct vents,
- warped/loose siding,
- cracks/holes under a rotted eave,
- open cellar hatches,
- separations/cracks where chimneys meet the house,
- rotted windows,
- loose fitting screen,
- openings where wiring or pipes meet the house.
These holes can be surprisingly small. You can find them in the oil deposited from the bats' fur and left on the roof or exterior walls – black or dark brown stains.
Such signs allow homeowners to find and seal the entries to prevent infestation. After seeing this, one should seal off most of them using caulk and leave a single hole for them to exit at night.
Step 3. Plugging Holes and Cracks
This action is the next step, done at night while the animals are out.
Bat-proofing a building is what you can do if a bat is in your house. The process includes:
- fixing and repairing roof sections,
- fixing and repairing loose moldings and flashings,
- exterior modifications,
- sealing of the soffit line’s perimeter,
- screening of chimneys and venting systems,
- using the right materials for all the above mentioned processes.
Another popular way of solving a bat problem in the house is giving the animals an escape route. This is perhaps the simplest and easiest solution that can be given to them. Whenever you see the creature, open the windows and screens, as well as other exit points. Turn off the lights and provide a bat a chance to leave the place.
Of course, there is always a prospect of catching it with a towel or blanket, but a procedure like this usually causes more damage than good.
If you know, there are a few bats in your home, but you cannot find the location, cut off the food supply. Remember that this is not as easy as it seems in most cases. The thing is, different food types attract different species. Some like pollen and fruit, but others prefer frogs, insects, rodents, fish, blood, etc.
Bat is in the house. What to do? Ensure all the fallen fruit is picked up, and the waste or garbage is disposed of or placed in tightly sealed containers.
Step 4. The Use of Exclusion Devices
As an alternative, homeowners can also install a check valve, a one-way door that will allow bats to leave the attic or barn without any chance of returning.
Exclusion devices are the most popular choice. They are permanently installed on all the entry points. As a rule, they are made of various materials and can be of different forms.
- PVC pipes
They are mostly chosen because they are smooth and slick inside. So, when the animals are inside, they have nothing to grip.
- Plastic/metal mesh netting
It is a cheaper but not least efficient trap.
Netting is regarded to be a durable and practical bat control option. Most distributors can offer various kinds of exclusion netting. You must install it across openings and protect significant areas from the infestation.
What for? Bats can easily wiggle through quite large-holed netting.
Looking for the most popular netting? Then you should get PE-Plus Premium Grade BirdNet. It is well-constructed and tightly knit. This is why it guarantees protection against picking or tearing by pests.
If you pick tubes as traps, place them over the entry points and holes in the soffit or roof. The fact is that such tubes allow the animals to leave your house without any possibility of getting back inside the building they've left. When the pests roost in long horizontal crevices, you can place the tube every 4-6 feet along the distance. This is how you ensure that creatures won't get out.
Generally speaking, all the devices mentioned above have one common feature: they are designed with a single-way valve/flap, which means that the pests can exit through this device but cannot re-enter.
The Use of One-Way Bat Doors
When it comes to fast and efficient bat abatement, many homeowners choose one-way door traps – valves. They are unidirectional escapes that allow the animals to leave the area through an opening or crack and don't allow getting back in again.
This is the most humane variant of exclusion that the Bat Conservation International Organization even approves.
The device is an exclusion instrument that allows bats to exit but not return. It is perfect for removing animals from eves, attics, and walls. It also works for mice, birds, and squirrels.
Today's market offers many styles and types of one-way doors. These can be hinged doors, netting, or exclusion tubes. Homeowners find alternatives like garbage bags and gutter guards, socks and bird netting, stockings, and caulk tubes.
The materials vary as well: plastic, wireframes, nets, etc. Some people even manage to build their doors. Generally speaking, these devices are very effective, and you won't have to handle or catch the animal.
Before you use them:
- inspect the chimney, mortar, and bricks that may form gaps;
- check ridge venting systems as they are feasible entrances;
- look for the gaps around the places where the chimney goes through the soffit;
- seal the gaps you find and then install a one-way door.
While looking, you can find plastic ridge vents that are deformed and have gaps. Sometimes the gap in the vent is even chewed. In this case, it is even better to replace it.
Bat Control Netting and Its Installation
This is another humane way to get rid of unwanted infestation. It works in buildings of all sizes and shapes. The fact it is cheap and environmentally friendly makes people worldwide use it and cause no trauma to bats.
Today it is primarily used to cover structures, objects, and openings that shouldn't serve as entry points to bats.
The pros of the bat exclusion netting are:
- a variety of sizes, forms and applications;
- a larger mesh configuration and the possibility of being used with big bats;
- a smaller mesh configuration and the possibility to be used with small bats;
- only one installation guarantees you won't have to take care of it anymore: it will pay for itself.
The widths and sizes of the one-way bat netting vary and depend on the manufacturer. However, it is always possible to find length that ranges from 25 feet to up to 250 feet, as well as widths from 7 feet to 17 feet.
The netting structure should be correctly tough to allow the animals to fly out and not return. The shape should be correct, like the one in art and sculpture. When it comes to bat netting installation, you can install it on lengthy gaps with vivid exit routes. Sometimes it must be extruded with the brackets to allow the animals' clearance.
All you have to do is drape the netting over the entry points, opening the ways out but blocking the access. The material is easy to cut, install and use. When choosing the material, pay special attention to durability because nowadays, saving more becomes more important than durability, which is the wrong way to eliminate bats. This is when a short-term application is not a variant. Remember that if the colony is significant, any netting can fail. Make sure you have some more material to be used in emergency cases.
Step 5. Bat Houses
If you are worried about the life and feeding of bats, get unique houses to allow the animals to settle there and not in your home. It is a top-rated bat removal product.
The matter is, most creatures don't leave the place even after plugging. They will seek shelter, and buying a bat house costs a lot.
A standard structure that Bat Conservation International approves costs up to $75, while a seven-chamber steel construction will cost from $210 to $300.

In case moth balls can’t cope on their own, place lights in those areas that are loved by bats the most. As these creatures like dark places, the lights will make them leave the territory.
How to Succeed in Getting Rid of Bats outside the House?
Most people choose a dog or cat repellents for this purpose. However, it is important to know that spraying any liquids directly on bats is forbidden and inhumane. Wait till all the animals are out for hunting and use a spray repellent on the areas they like roosting.

One-way door can also be used at all entry points, allowing the bats to freely leave the territory. The best time for using them in June and July, as this is the so-called maternity season perfect for complete exclusion of pests.
7 Ways on How to Eliminate Bats in Walls
If they have already penetrated inside the walls of your house from the attic, start acting immediately:
Look for the smallest openings on the outside of the house. Pay special attention to cracks under the roof’s eaves or to the openings that are in the siding. Don’t forget about air conditioner vents and chimneys, as these are their favorite entry points. Normally, oil-darkened narks give a hint where the bats are.While repairing holes and cracks, use wood, bricks, and cement. This should be done at night when there are no animals inside the walls.
Thus you won’t trap them.
Spray repellents around the areas where the bats are, as well as underneath the eaves of the roof and siding. Today’s market suggests several effective repellents. Click here to find out more about the best bat repellent sprays, liquids and gels. When you have chosen the right spray, use it along cracks and openings in order to reach the inside of the wall. Pests dislike repellents, so they will leave the area soon.
Dr. T’s Bat Scat and Sudbury’s Bat Repellent are the most effective and widely recognized best control products. However, they never guarantee 100% results.
Why? If they are sprinkled in places where only several bats are roosting (double walls, tight attic spaces, boxed-in areas, attic ceilings), they encourage only these bats to leave the building, while others remain. The effect is only temporary and lasts for 3-4 weeks. Most animals will just move to some other parts of your house.Chemical repellents shouldn’t be used in case humans and pets are exposed to the inhalation of odors.
Most people are very sensitive to them, so avoiding direct contact is crucial.
- How to control colonies of bats without chemicals? Another possible way to use bright lights, as they may repel pests.
For example, you can illuminate attics using about 150-watt bulbs, directing the light at all the entry points. They are to be turned on after the bats have already left their location for feeding.
Illumination is very successful, but not in all cases. When bats infest a huge building, lights can hardly work.
- Push fiberglass into wall, under floors and roofs to deter and discourage bats. Complete fiberglass insulation is unnecessary, but a few layers will be very helpful. Direct exposure will irritate the animals and make them leave.
- Air conditioning is another variant of bat pest control. Cool air and drafts within the location repel bats from your building. Direct the breezes produced by electric fans will prove a success.This approach works in places where exclusion can’t be achieved.
Turn on the air conditioners during April and May to discourage the pests from roosting, as they prefer high temperatures to the rear young generation.
- Some people claim that ultrasonic noise can be efficient as well. However, none of these bat control devices are 100% successful in the process of repelling.
- Contact a professional agency to make sure you have done everything in the right way.
