QUESTIONS & ANSWERSAsk BCM a Question
I’ve got bats in my storm shutters. And I don’t want them in my storm shutters. :-) So I need some help on what to use to house them. And how to encourage them to move.
To discourage bats behind the shutters, open the shutters/prop them out away from the building. Bats are there because of the crevices, if you make the crevices too big, they will abandon them. I recommend waiting until August so the young can fly, and also propping them open after sunset so that your bats don’t have to fly around in the daytime and be picked off by hawks, etc. The only way to keep bats from entering the shutters is to seal them. This might involve placing window screen behind the louvers, and caulking them to the building. If they are decorative anyway, this should be relatively easy. Placing any of our bat houses near the shutters will have bats move in almost immediately; for best results place it on the building itself. Please see https://batmanagement.com/pages/lc-bh-overview Some models I suggest would be the single chamber DayRoost (essentially mimics the shutters you have), 3 Chamber DayLodge, and the ColonyLodge.
I noticed the landing area on your houses are smaller than other companies?
The landing area is at least 4’’; it is deceptive on some photos of the DayRoost because of the camera angle…some photos it looks like there isn’t a landing area at all. Truth be told, once you get a bat house that is 3 or more chambers, bats actually land on the baffles themselves, rather than the landing plate. This becomes apparent after watching video of bats returning to bat houses. The landing plate is most used if it is a single chamber bat house mounted against something slippery like vinyl siding; in that situation, a landing area would be critical. If mounted on rough brick, landing areas aren’t needed at all, as the brick -is- the landing area. - Thanks, JC
Do you have videos of how to assemble your kits, specifically the DayLodge triple chamber kit? And for the Bat house mount kit? Want to make sure I understand and can assemble it before buying.
The DayLodge & DayRoost videos, which include demonstrating mount kits, are here: https://batmanagement.com/pages/video-bat-house-how-tos
The manuals are here: https://batmanagement.com/pages/manuals
I’d like to know how to attach the assembled daylodge to the mounting kit. Do you just screw thru the 2x4s from the back of mount into the sides of the daylodge?
You should have received two rather long (6’’) TimberLOK screws with a 3 chamber DayLodge. These are the main screws for mounting. The intent is to predrill 2 holes in the top of the FRONT of the bat house, just 1/2’’ or so down from the roof. The long TimberLOKs go thru the front, thru the roof block hidden under the roof, and then into the 2x4 mount. Using this approach, I cannot imagine the top of the bat house separating over the years. The TimberLoks are so good and the wood is soft you don’t really need to predrill, but it helps to get it going straight. If you don’t have those long TimberLOKs anymore you can buy a small pack of 2 at Lowes or Home Depot for a few dollars. See the manual here, the last page of the DayLodge pretty much shows the screws about to go in… https://batmanagement.com/pages/manuals You can put 2 deck screws thru the landing plate into the lower 2x4 of the mount to finish it off, but really those TimberLOKs are holding it all together.
We were wondering if there are any stains or paints that we shouldn\'t use or if most are fine and we just need to give it the proper time to dry and offgas.
There is no particular paint or stain that is bad for bats. There is no data to support bats prefer one or the other or none. The bat house will certainly last longer if painted/stained. Because of the plastic roof and mounting scheme eliminates the roof wear, the part that will weather is the front, so be sure to double/triple coat the front. Thick paint will fill in the scratch marks on the landing area, so after painting re-scratch with a utility knife. Don’t forget to scratch all around the back vent. Truth be told, on 3 chamber and larger bat houses, bats actually land on the bottom of the baffles much more often than the “landing area”, but it should still be scratched.
Do spray-on attractants really attract bats to a new bat house?
Design, construction, and placement of the bat house will ultimately decide if you get bats. There were controlled experiments to test bat preferences (choice of substrate, orientation, landing pads, etc.). In these tests there was no statistical difference in their choice of guano treated vs untreated. While a specific “spray” was not tested, there also does not seem to be -any- research actually backing up manufacturers claims. We always tell folks not to waste their money. If you have a well-designed bat house installed in a good location, bats will use it, when they need it. Patience is important.
I have heard sketchy information linking bats (among other animals) to corona viruses. Also, I understand that bat guano may be hazardous after incidental contact. Is it safe to be sheltering bats, especially in proximity to one’s home / living area?
The short answer is yes it is safe. I wouldn’t move it for a few seasons; attaching to buildings often is very successful. If you get a bunch of bats, they will splatter dropping on the siding around the house. On occasion a young one won’t survive and you’ll find it on the ground below the bat house. As long as everyone in the house knows not to play with wild animals/downed bats, you won’t have a problem. The guano is possibly hazardous if it is in large quantities and disturbed after many years; you will never have this scenario with a backyard bat house.

What is the best bat house for Tucson, AZ?
For summer use I suggest mounting a bat house in -full shade- in your area. Probably any color is good; just keep in mind it really must be in full shade all day. Best bat houses in your area face northeast or east. No bat house works on poles in your area, but rather must be installed on buildings or other large structures. You might try a second bat house on a different side of building, as keeping a few bats around in winter might require another bat house in a different location. Perhaps a location that gets a few hours of direct morning sun and then is shaded. This gives bats some options and by watching where they go you will learn what they are looking for in your local area. You have the Western pipistrelle (“Canyon bats”) and Mexican free-tail bats in Tucson year-round. Both of these -could- use buildings or bat houses year-round, most famously the free-tail bats are in certain bridges around the city and put on a good show in the summer.
Is a \'day lodge\' only used for daytime resting? I want something that the bats can use for long term resting and perhaps even hibernating.
Bat houses are ususally intended for female bats to raise young in the summer. Indeed they spend all day in the bat house, leave at dusk and return at dawn. The reality is that some may not exit any particular night, and they might start returning an hour after they leave. The same bat house that female bats raise young in when mounted in full sun, may also attract a few solitary males when mounted in the shade, or even a different species. In certain parts of the country, you could have bats year-round in bat houses, even different species at different times of the year. If you want a wide range of bat activity, the best idea is to install several bat houses in different locations so bats have a range of microclimates to pick from.
I live in Petaluma California which is southern Sonoma County. We have mild winters and two and three-quarter acre property. I’m wondering where I should place a bat house. Summers can be very hot sometimes reaching 106°F. Should I be looking for shaded area near the redwood trees in our yard or the backside of the barn on our property?
I don’t think you can lose with the sunny side of the barn but put the bat house high enough so that the eves of the barn shade the bat house in the afternoon. Ideally you’d want it to get hit with direct sun in the morning, then shaded in the afternoon. It is best to try multiple bat houses in different locations if trying to attract them to a new location. The DayRoost bat houses we offer are inexpensive for those kinds of experiments.
In central NJ, I have a tiny creek running by. Also, I am on a hill, with a lots of forest. What is a good placement?
Hello- ideally you want a position where the bat house will receive full morning sun, and some shade in the mid-to late afternoon, about 6-8 hours of morning sun. It could be mounted on a building or a pole; trees are usually too shady. If on a pole, about ~30' from trees is good so bats can avoid predators For more guidance please see our All About Bat Houses manual at: https://batmanagement.com/pages/manuals
Hello- some of the approved and recommended houses here are less than 20-24 inches in length; however, this website and others state that you need to have one at least 20 inches in length. I was wondering why the discrepancy and are these smaller approved houses still okay?
These are general suggestions and only one measurement; a successful bat house is going to be a combination of width+heigth, but also depth, resulting in mass, and construction materials. Generally, a bat house with a lot of mass placed on a pole and can be expected to be attractive to bats, because overall the mass lets it stay warm longer in the night. But a tiny 6'' wide single chamber bat house on a post may never get bat use; but the same 6'' wide bat house mounted on a brick chimney may very well be successful. We use a thick plastic exterior as it warms quickly and bats tend to occupy it first over similar all wood and all aluminum bat houses. The interior is still wood to gain mass. The less expensive DayLodge uses a thick black plastic roof one what is a more typical wood 3-chamber bat house; with the mounting fasteners pinning the entire bat house directly to whatever you are mounting it to, which will keep it together much, much longer than previous designs. -JC
We have a shady backyard, an Eastern facing wall that gets good sunlight, and a chimney (we use a wood stove in the winter). We're wondering which location would be the best place to mount a bat box when none of the options seem to be ideal. We are trying to attract wildlife with lots of native plantings, etc to our 1/4 acre and are trying to attract bats next! Thanks in advance for your help!
Mounting on buildings is actually almost always more preferable to bats than on a pole or tree. The building absorbs heat all day and slowly releases it at night, so bat houses mounting to structure don't cool off as fast. Depending on your location, you might get a few bats in any location at certain times of the year. So, I would look for mounting on the chimney, and even 2 sides of the chimney if possible; the sunny & shady side. -JC
