hi! we enjoy these guys during their night flights! But concerned about coming out too early, with all the scare about health and new diseases. I thought they came out too early last year which changed the gang from at least 6 to 7 to 3. Now their out today 5/13, which will be pretty cold later this morning. Will this kill off some of them?  bob

I have a brick chimney attached to a garage on the back of my property that no one uses.  It is the perfect place to mount my new bat house, but the chimney is only a total of 10 feet high. Will bats roost this low?

You just ask any real estate expert. He will guide you properly. Bats can scare kids, so it is better to get them out of kids reach.

I apologize in advance for the long post, but read on if your interested. For the last 8 years or so, we've had a few bats using the upper wall of our front porch for an overnight rest stop. The wall is about 15 ft. high and the ceiling meets it at a 45 degree angle, so it is a very sheltered area. Beginning in mid April a few bats arrive around 1 AM every night without exception and stay until 5 AM when they all leave. By early May we are up to around 20 or so with young ones as well. After the young ones appear, they remain during the day along with 1 or 2 adults. This lasts for a couple of months and then they all leave during the day and return again to spend part of the night. In October, there are fewer bats each night until they leave until the next spring. This annual event began with only a couple of bats but we seem to be growing by 2-3 a year. We live in an area with hundreds of caves and numerous colonies, Nickajack Lake, Cloudland Canyon State Park and Pigeon Mountain just to name a few. We love having the bats, but as you know they leave a very impressive pile as a gift every morning on the threshold of our front door. If we leave the front porch light on, they will not come, but we want them, just not over the front door. The problem is how to keep them overnight, just in a different place. All the bat houses I find seem to offer them a place to spend the day, not the few hours at night that they use our house for. Any meaningful thoughts, comments or suggestions would be appreciated. Thanks

Bats occasionally do bite people or kids whoever and so it would be better to keep both of them away. As for liability, it would be Your responsibility to get the kids treatment and all may be.

Hi

Bats don't roost at floor level, so assuming you are just insulating the floor I doubt the bats will care.

Need to insulate the attic but don't want to harm our long-established bat residents!  Can't find info on whether the non-formaldehyde fiberglass insulation will harm them.

What's up, y'all?

I have a medium-sized cedar tree that fell in the woods behind my house (which is a little over 1/8 of a mile from a stream and has a $#!7 ton of mosquitos which I want gone, so it would be perfect for bats) it is about 6" in diameter on average on the trunk. If I were to drill holes in the wood with a 7/8" drill bit I have, would that work as a bat box? I live in northern Virginia, near DC, so if it would work (as shown in the attached image) what colors should I paint it?

By the way, this is my first post on this forum, so tell me if I'm doing this wrong or anything like that. My Username comes from how most people try to pronounce my last name, "Towle" (like "Toll Booth) but also from the character on South Park.  

Keeping the lights on will attract more night flying insects and in turn may even attract more bats to your home. Window screens will help and having your house properly sealed or use the industry term have the house excluded. This is best left for a company with bat experience when done improperly many bats can die and or your house will still let bats in. Not always cheap but a heck of a lot cheaper then rabies shots and nothing can beat piece of mind when you go to sleep at night.

My house is on a .4 acre lot adjacent to a flood control creek in north Sacramento, so there's water available most of the year, but it occassionally goes dry in the hottest part of the year.

Main question is heat.  It can get near 110° for a few weeks in the heat of the summer and was looking for a design for a house to affix to a pole.

What would work best in this environment?

Thanks
