Anybody have any experience evicting a colony of BATS from a house?

So I just found out that a place I'm buying has a chimney full of blood sucking stinking arse bats. They're possibly in the attic too, but definitely in the chimney. My first inclination is to build a bigass fire and burn/smoke them out. But what if it kills them and I end up with a chimney full of dead bats? What if they're not in the flue and are between the flue and the brick and I just slow roast bats everytime I build a fire? I don't know these answers, so I call a chimney sweep for advise, and listen to this horseshite. In Louisiana they can't legally touch a chimney with with bats in it from May 15th to August 15th because it is bat breeding season. WTF??? I ask him about my fire building plan and he says it might work, might not. Might end up with a chimney full of dead bats you can't get to. So I call a wildlife trapper guy and he reiterates that he can't touch a bat until August 15th. But for $400 he can come inspect the place and see how they're getting in. And after August 15th he can come get them out...... for $3,000-$5,000 dollars.
So now I'm asking the good folks of the OB. WTF do I do about these Gdamn BATS??

My parents had the same problem few years back. Not sure where he got this idea, but it worked for my dad: Go out late this evening and find the hole/crevice where they are going in and coming out. Should be easy to spot, because once they start coming out to feed, it will be a steady stream of the little bastards. Use some poultry netting and make a funnel, with a downward angle, and cover the hole/crevice with it during the day. That evening, as they go out to feed, they cannot find their way back in. It's like a reversed fish/crab trap. After just a couple days, hopefully they've all relocated.
ETA: The bats my parents had were living between the brick chimney and the house. Apparently they can get into some tight spots.

If can find where they are entering /exit can make a one way exclusion device that covers the hole. Google one way exclusion device for bat removal usually made out of plastic a sleeve that allows them to leave but they can’t get back in. Buddy did it and it worked. May have to cover chiming with something you build out of wood or plastic with tub on it so they can exit but. Any get back in.
Buddy had a small hole in eve that they were using. They all left with in a few days and could not get back in and found another place.
Once know they are gon perennially block hole.

The funnel is a good idea.
To aide in it knock a hole in a neighbor's house.
They'll go there

They don't like bug spray. I had to get rid of some that made themselves at home in a house was working on. had to be around a hundred living between the soffit. Me and another guy went up on a cherry picker to flush them out, biggest mistake of my life. Hit them with the bug spray and they started flooding out right into my face and chest. one got stuck in my shirt thought I was going to have a heart attack.

I would read this article before you go down the route of DIY removal tactics.
How to remove bats from your house
Couple quick notes:
- removing or excluding them now, during breeding and pupping season, may result in the adults leaving but the young trapped inside and waiting to die.
- if you don't seal up all the holes (they can gain access through something as small as 1" × 3/8"), then they will just come back. So make sure everything is sealed.
- adding a bat box nearby may help discourage them from trying to gain re-entry into the house. Plus bats are cool and eat lots of mosquitos.
- depending on the species, they may have a federal protection through the Endangered Species Act. In that case, any sort of intentional harassment or killing is very much illegal. So if you are building a fire specifically to kill the bats, that's a no go. However, if you just happen to want to build a really smoky fire in June and it happens to push the bats out, you're good. Sounds like you have a bunch of green wood you just HAVE to burn, right?

Why not make a fire at night, once they are gone? Let it burn until they come back in the morning, they won't enter at all and will hopefully find a more suitable home.

I think you'll want to wait until after the breeding season, or, you'll have a bunch of adult bats trying like hell to get back to the young. Sets up a bad scene.
My in-laws inherited a place that had the largest residential infestation the bat guy had ever seen. 15,000 bats, 3 different species. They had to wait until after the breeding season to put the one-way check valves on the exit points and close up every possible opening. They can squeeze in any spot/hole the size of your finger. It cost a bunch for the in-laws, maybe $10k-ish. And as soon as they evicted the 15k bats, the bat guy was getting dozens of calls in the next few weeks from people and business where they moved in. Not a bad business model, chasing the same bats all over the county.

Did the home inspector not find or note in the report?
Posted on 6/17/21 at 10:13 am to LSUballs
Yes, I did and a bunch of other people in my neighborhood. I got rid of them myself. Just need some window screen and gorilla brand duct tape. Very easy to do and works on the first night if done properly.
I knew we had a few living in a weephole, yes, a weep hole in the bricks above a window in my bedroom wall. They didnt bother me much until they started waking us up at 3-4 in the morning with all the moving around in the wall. I did the one way deal with the screen and gorilla tape and say outside one evening in my outdoor kitchen waiting until dusk. I was shocked at how many I actually had in that tiny space. Easily 40-50 of them. I thought I had 4 or 5 of them living in there. I left the screen up for 3 days after just to make sure then stuffed the weep holes with pieces of a wire scrubbing pad to make sure nothign got back in there. They then went to my neighbors house and I showed him how to do the one way trap and he got rid of them also. Had a buddy who had hundreds and hundreds of them living in his attic. He got rid of them the same way and was the one show showed me how to make the screen contraption.

Thanks for all the feedback. I'm going to go out there and see if I can find their point of entry. If I can find it I'm pretty sure I can seal everything up and install the one way exit thing over the hole. But like previously mentioned I'm not sure what this will do to all the potential bastardized baby bats still living in the chimney. Then there's the bat shite smell I have to contend with. It will drive you bat shite crazy

No, he did not mention a bat infestation of any kind.

Put the screen over the hole and make sure it extends down a good bit below it. Leave it a little loose and tape it completely on the top and both sides all the way down. It will work. Not sure when bat birthing season is though.

I've got an elevated house and have had bats roosting under the house in gaps between the house and decking. And some in the attic. For the last two winters they showed up in January. Last winter I counted 200 returning at dusk. My builder gave me a tip that helped - they hate the smell of Vicks VapoRub. I used a long pole with a paint brush duct taped on to dab Vicks around their entrances. It seemed to work, but they would move to another part of the house - lots of gaps under the house. I spent at least a month chasing them around different entrances. And then they started using the attic and entering through roof vents. For that I got some Peppermint extract (it's in the Vicks) and a sprayer and hit the spots they were using. Eventually they went away.
I also put up a bat house in the garden - but there is no evidence that it's ever been used.
If they have young in the chimney I doubt that they will abandon them because of smell. And if they do; you won't like the smell that results. You probably have to wait until they are done breeding.

Just wait until dusk, then go out there. Get there early obviously, but let them show you where they come out!
As said, put a one way door after they leave. I can't imagine that shouldn't mostly do the trick.

Thanks for the tips. What time do bats bail out of their bat lair? I’m gonna get some beer and try to find their point of ingress/egress this evening. Will 30 minutes before dark be in time?
