Bats flying in through my doors

So recently we started using another door on our house. Its a 10 foot door I believe very tall. Anyways whenever we use it at night bats seem to fly into the house. This has happened twice. Any ideas why they would do this? The house is almost 200 years old. i do not have any lighting, in that room or outside. We do not have a bug issue that I know.

My best guess is the mosquitoes follow us then the bats follow them. I was sitting in my front yard the other day and there was a sworn of mosquitoes around me and a tiny bat was flying around me picking them off.

Yeah, they do eat a lot of mosquitoes. I would work on limiting the number of bugs near the door and see what happens to the bats.

How long is the door staying open?

A 10' door. That certainly isn't helpful.

thanks. thats a great idea. Honestly haven't thought of that one yet. It is a large over hang and we have seen bats swoop down under the over hang where the door is. I have watched them at night.

just long enough to walk in for the most part. Sometimes my woman is a very slow slow slow walker.

I agree that they're probably drawn there by mosquitoes, and don't know how feasible this is, but, if you have a receptacle on the porch, you might try a fan, possibly switched from inside the house or on a timer. We generally sit on our front porch for a bit in the evening, and use a small, maybe 6" fan on a plant stand to keep the mosquitoes off of us. Our situation is obviously easier because we just switch it on when we go out and off when we go back inside, but, depending on your schedules something like a timer might work. If the door is actually 10' tall, I might also think about a 30-36" screen at the top of the opening, assuming they are coming in high.

Bats like to roost in gaps, cracks, crevices. Iíve known of them to roost right against a door so that when it opens they just naturally move right in. Also if a storm door doesnít seal well they seem to love that gap which puts them right next to the main door.

Search to floor area at the base of the door for shiny, rough shaped droppings as that would be bat droppings. If you do, then they are roosting pretty much right above that.

Can you periodically approach the door from outside, meaning donít open that door, but use another door, take a good flashlight and search the perimeter of that door carefully. Small bats donít look like bats when roosting so be ready for anything. Also, do you have shutters? Those are good roosting areas. Look for the same droppings below the shutters.

Yes I have seen droppings around certain areas. Not a lot just like one or two here and there. I will try that with a flash light. And yes we do have shutters. We have no working lights outside. I need to install them.

Thats a good idea on the fan too.

Thanks for eveyones help so far.
