bat hanging from a deck

Have you found a bat on your porch? Or perhaps you’ve noticed droppings? Does this mean bats have found their way into your attic? Not necessarily.

Porches and overhangs make excellent roosting spots. After feeding, bats will often land to rest and digest their food before continuing to feed. They tend to feed on mosquitoes and insects that are attracted to the lights commonly placed near porches. While good for keeping the insects away, this can be a nuisance, and preventing bats from roosting on porches can be quite the challenge. We have a number of tips and tricks for homeowners, to try to prevent bats from picking your porch to roost in. 

Tips and tricks to stop bats from roosting under your porch.

Firstly, if you can wait for the season to change, the bat will probably leave on its own, when the weather turns cooler. If not, some people have had success hanging helium-filled Mylar balloons close to the roosting spot, the balloons need to sway to be effective, or by suspending aluminum foil.

If you don’t like the idea of what might be considered unsightly by some, try hanging wind chimes or mechanical owls, basically more aesthetically pleasing versions of aluminium foil. These are all fairly easy solutions but are not as effective as our next suggestion.

A more long term solution would be to modify the surface on which the bats are roosting. Bats like a material that they can hang onto easily, so securing something like Plexiglass (Perspex) to roosting sites won’t allow the bats to hang as they could on brick or wood.

Lastly, remember that bats are actually good to have around, as long as they are not hanging around your home! So why not try adding a bat house to your property, which will provide them with an alternate roosting site.

When to call the experts.

It is important to remember that if you find a bat on the ground during the daytime, it is likely to be injured or ill. Bats are wild animals so if they are in pain or in a panicked state they may try to defend themselves. Always take precautions, you should wear gloves and handle bats as little as possible, if in doubt call the experts.

We are happy to advise you on how to determine if you do have bats in your home, just give us a call. If you do have a bat problem, we can certainly help to get them out and keep them out.

    Thanks so much for this info. We just found one bat roosting under our deck . We just had a bad tornado hit our neighborhood lots of tree and roof damage. Think he must be seeking new safe place. I will try your ideas let you know what works. Thx

      So sorry to hear about the tornado! I am sure you are correct about the bats being displaced after it. I hope the suggestions work!

    We installed plexiglass panels (two panels, each about 2 feet wide and 2 feet high) right under the roofline in the corner of our porch where the bats were roosting on the bricks. That solved the problem right away. Thank you for the idea!

    We had a bat stay for a few days and finally called the city's animal control officer who removed it. He said it was most likely sick since it did not move. I assume it had to be euthanized so it wouldn't get other bats sick. Now we have another that keeps visiting. I was thinking about getting some of those magnetic door screens to cover the majority of the porch so they couldn't fly in easily. Maybe I'll try some mylar balloons first. I guess when they have helium, I could tape them to the floor, then when they go flat, I could attach them to the top so they end up in the middle of the porch entrance. Would hanging sachets of peppermint oil deter them from visiting my porch? Or something else? I'm tired of cleaning up the feces and afraid that it will make us sick. Thanks, Nancy

      Hi, well your porch must be an inviting place! I would try to think of things to make it less comfortable (but in a safe way) for the bats. You could try using a garden hose a few times because they want a dry spot. Peppermint oil mixed with some diluted soap where they like to huddle will likely make them want to move on too, you could try applying it in the evening when they like to leave for dinner. Usually it takes more than one application. I hope you have success!

    I have a bat that has apparently been roosting near the ceiling of my front porch (12-15 feet off the ground) all summer as evidenced by the droppings I have been finding. We saw the bat for the first time this weekend. It has not moved in at least 24 hours. It is roosting from the top of the brick wall. Any suggestions on how to chase it away without injuring it, and assuring it doesn't return?

      Hi, thank you for keeping the bats wellbeing in mind as you plan to move it from it's favorite spot. It likes the spot because it feels safe and dry. A garden hose shouldn't hurt it, and if it happens a few times the bat may decide to move somewhere else. Alternately, peppermint oil mixed with a surfactant like diluted soap will irritate the bat enough to make him move. You may need to reapply every week or two until it leaves.
