How to Keep Bats from Hanging Outside Your House


Getting rid of bats outside your home may increase other pests they are famous for controlling. They are known for eating thousands of pests like the mosquito. However sometimes they choose places to live that are just too close for comfort as they are also famous for carrying diseases of their own. When the bat gets to close or their numbers get to large; it is time to know how to get rid of them outside your house.

Sometimes the bats are not using your home as their resting spot. They may just be too close to your home and if you don’t get rid of them your house will be threatened.

There are some preventive measures to keep bats from finding your area inviting:

  • Wood: Bats love to live in dead trees. If you have a tree that has died, cut it down and remove it. If the bat can’t find a place close to you, then they move further away in search of a home.
  • Standing water: If you have an area that always has water sitting in it such as bird baths, or rain catchers- get rid of them. You are attracting the bat with a consistent source of water.
  • Insects: The main food source for the bat is insects. If you can resolve the insect population around your home, you can reduce the chances of bats coming near it.

How to remove bats from your walls

If the bat has chosen your house for their home and you know they are living inside your walls it will take some time and effort to remove them.

Choose an appropriate time for removal

Getting rid of bats outside your house must be done during the right season. This will ensure their survival and ability to continue getting rid of pests.

  • You need to know if the bats are nursing/nesting. If you remove the mother bat before her pups are ready to care for themselves, they will die. It takes approximately five weeks for newborns to take care of themselves. In the United States and Canada the maternity season for bats is between May 1st and August 31st.
  • The bats will hibernate during winter months and if you evict them during the cold, they will not be able to find sufficient food to survive. You’ll increase your pest population considerably if you kill off all the bats around your area.
  • You can relocate bats to a bat house if you which to do so. Some people enjoy having bats around because they help control insect populations in and around their yard. They are especially useful at keeping the mosquito population in check.

Locate where they are living

Bat droppings will be your best clue to finding where the bats are living. The bat guano (droppings) sparkles in the sunshine and has a crumbly texture. The guano makes a great fertilizer but it is very unsafe to inhale. Inhaling to high of a level will produce a disease that is similar to flu symptoms. Those with the highest risk of getting sick from inhaling guano are the young, old and anyone with a weakened immune system.

If you cannot find signs of the guano, then you can wait until dusk when they will begin flying out of their homes to search for food. Remember when looking for their possible exits that bats can fit through holes the size of a dime. Common entrees or exits are:

  • Where your wall meets the eaves on your house.
  • Places the flashing or boards have come loose.
  • Poor fitting or broken screens.
  • Where your pipes enter your house.
  • Where your porch attaches to the house.
  • Cracks where siding forms a corner, or where siding meets your chimney.

Don’t allow the bats to return

Once you know where they are living and after they have flown out to search for food, seal the entrance. You can staple or nail a screen over their entrance. The following night, remove the screen so any that remained behind can also leave. Bats do not feed every night, so you will need to repeat removing and replacing the screen for several nights to ensure all the bats have left. Once you are sure they have all left; you can then use a more permanent seal on the entrance.

How to remove bats from your shutters and porch

If you have shutters on your home and the bat chooses them to live it can be quite annoying. They will be noisy with their scratching and squeaking and you will want to remove them and then discourage their return. Having them flying in and out of your porch will also want to be stopped.

  • The bat does not like light. If you are able to direct bright light toward the shutter or inside of the porch they will not want to stay. The down side to this method will be lights also attract bugs and it could be counter effective if the light draws the bat to a food source.
  • Check your state guidelines on bat repellents before using. In some areas it is illegal to harm bats. Not all repellents are legal to use, and some states do not allow the use of any chemicals. You need to make sure you are choosing legal ones before putting them out.
  • There are bird repellents on the market that are sticky. If the bat crosses this stickiness they will not like the feel and will be discouraged from living there.

Mothballs

The chemical in moth balls, naphthalene has been approved to use on bats in some states. You can place the mothball around areas you think they are living and they will not want to live where this scent is present.

Natural repellents

The fragrance some natural items emit will discourage bats from seeking shelter where they smell it. The scents irritate the bat and they will find it very unpleasant. You will need to ensure the scent is strong enough and lasts for several days. Some of these natural repellents include:

  • Cinnamon
  • Human hair
  • Peppermint
  • Green tea
  • Coyote urine
  • Eucalyptus
  • Menthol

Electronic bat repellent

Electronic bat repellents emit sound waves which constantly vary and change before a bat can adjust to the pattern. This annoys the bat which uses sound waves to determine where objects are. When this constantly changing sound continues in your area they will be encouraged to move.

The sound waves coming from the electronic bat repellent will interfere with the bats echolocation. These are two that have been effective:

  • Transonic Pro: This is an ultrasonic bat repellent and will disturb the bats communication and sleep. It can be used with batteries allowing you to place in varied locations if power is not available.
  • ET Pest Control: The ET Pest Control will emit varied sound waves at different frequencies. The unit can be plugged into any household outlet.

Bats can become a pest and a danger when they decide to use your home and property as their nesting place. You will want to remove them from your home and areas close to your house; however, they are protected by some state and federal laws. To ensure you are using appropriate measures, check with your state laws before beginning removal of the bat from your home.​
