Hey everyone! I'm struggling to find a solid solution for a bat problem in my apartment and hoping you can help. I've had two young bats fly in over the past week, and while I like them outdoors, I don't want them in my home. I live in an old Victorian house that's seen better days, with holes and cracks popping up everywhere. A pest control guy confirmed there's bat activity but won't take our case because of the condition of the house and nearby abandoned barn. I've tried sealing many gaps with my landlord, but the windows are still an issue.
I've been told bats often slip in through the gaps between double windows. I've attempted using self-adhesive foam weather stripping, but it made it hard to lock the windows. I want to keep some windows open at night, especially since it gets hot here in the summer, but I don't know how to install weather stripping without compromising the locks. I've heard v-seal weather stripping might work. Can anyone share their experiences or tips for bat-proofing windows while still being able to open and close them? I'd really appreciate any guidance!

What if you just hire a clown to hang out outside? It could distract the bats! Just kidding! But seriously, bat-proofing’s tough, just keep sealing those cracks and good luck!
I totally get your frustration! Those old double-pane windows can create all sorts of gaps. Sealing them up is a must since bats can squeeze through tiny spaces. Personally, I found that standard weather stripping doesn’t always cut it. V-seal weather stripping is a good idea; just make sure you place it correctly in those side tracks where the pulleys are. Essentially, you want it to sit where the window meets the frame, sealing off that gap without impacting how the windows operate. It might take a bit of trial and error, but it should help keep those bats out without locking the windows down completely. Good luck with it!
Hey! For bat-proofing, consider investing in a foam strip that fits snugly between your windows. It’s pretty effective and should allow for a cool breeze while keeping the bats out. Plenty of folks use something similar for air conditioners, so it should be a solid fix. Just remember that you may still need to patch up other entries in your home as well. Good luck!
I do have some foam strips, but I’m looking for something that looks nicer and is more permanent. Thanks for the suggestion, though!

Thanks for the tip! I’ll give that a shot and see if it works out. Appreciate the input!
