BCM Four Chamber Premium Bat House
QUESTIONS & ANSWERSAsk BCM a Question
It seems the pups are falling out. I have been reading about pup catchers. Do you recommend I install one of these?
There are some conflicting observations about the usefulness of pup catchers. PA Biologists observed pups never being recovered on pup catchers at all, while others have observed pups climbing back into the bat house. It probably depends how old the pups are, and the reason behind them being out. One theroy is mothers build up toxins from pesticides, which are relased into the first pup they have. BCM offers a Pup Catcher here that is robust enough to use many years: https://batmanagement.com/products/bcm-pup-catcher There is a DIY solution here: https://batworld.org/bat-house-pup-catcher/ that I like because it is adaptable to whatever bat house or roost you are having problems with. Note the “pup catcher” and it’s parts will deteriorate over time and should be considered something that is a temporary fixture to your problem roost. The lower board that supports the catch pocket makes a great perch for raptors that may pick off all the pups, so only use this device if you really have a problem and remove it promptly.
I have some spruce trees that I have been told they will die in ~ 5 years. If I trim off all the branches, and leave just the main trunk would this be a good “pole” for the bats?
As long as enough limbs are trimmed off so that the bat house receives direct sun most of the day (especially in the morning), that snag would be just fine. Be forewarned if the bat house is shaded it probably won't work. Mounting a bat house is a little trickier because the tree is round and uneven. If using our pole mount kit or something similar, attach the pole mount brackets straight and flush with each other on a flat surface using a few pieces of scrap wood. The mounts can then be lag-bolted onto the tree, and the scrap wood discarded. The two brackets should then be on the tree in the proper spacing and position for the bat house. In addition, stainless steel lag bolts should not corrode and kill the tree like other materials.
I actually have a perfect tree with the right sun exposure. Can you give me suggestions to mount the Premium Bat Box on this tree?
If your tree gets quite a lot of direct sun, it may be suitable. Here are some steps to help you attach the pole mount (which is two separate pieces of wood) to something round and irregular like a tree trunk: 1) Lay out the pole mount brackets square to each other with the proper spacing on a table. Test fit the bat house onto them to be sure you have them at the correct distances apart. 2) Temporarily and securely attach scrap wood to both ends of the pole mounts, so that you essentially make a rigid “frame”, which will keep the proper spacing and orientation of the pole mounts. 3) Take this “frame” to the tree, and screw the pole mounts to the tree using stainless steel lag bolts (not included in the kit). I believe if you do not use stainless steel lag bolts you run the risk of killing the tree! That said, if the tree is not healthy, any bolting into it may kill it. 4) You should not be able to remove the scrap wood that was holding the mounts flat and parallel. If not much twisting or shifting occurred, the bat house should mate nicely with the mounts.
What is the best time of year to install a new bag house? Location is in Southern Missouri.
Hi in southern Missouri you possibly may have bats active there year round, so anytime is good. For many of us March starts into summer bat season, so you might wait until then to save the bat house from being exposed to an extra winter. FYI those readers in Gulf Coast states, the Southwest, and south half of CA, you do have bats active year round and anytime is great.
I bought your bat house but don’t know where I put the manual. Is it available for download? Or can you send it to me please.
Hi just send a request to firstname.lastname@example.org so we have an email to send it to; thanks!
We are interested in having a bat house on our property in the "wild area" - it has a natural spring that makes it hard to grow, so we generally don't mow up there and have a lot of wild flowers and plants (walnut trees and willows) up there. My questions is - would that be a suitable area or do they need more buffers from wind and such?
Hi - while windswept areas may not be completely ideal, it is certainly not a deal killer. If you can place the bat house ~30'-50' from trees, that will buffer some but more importantly provide immediate cover for emerging bats from predators and wind. Sounds like you have a nice place and the spring with the wetland will generally provide insect diversity for the bats.
Well there be instructions on where to place it?I'm a retired farmer and do not have any more buildings on my farm. I was thinking on placing it on the southside of our large farmhouse about 100 to 200 feet away will this work?? I have a really large dance Grove to the north of our house. We have a yard light that will be approximately 100 feet west of there.
Each bat house ships with a 16 page paper manual. A few pages of that show how to make a pole mount to attach the bat house to a 4x6x16' post. Placing it on a post near some trees, but not shaded by trees, where it is in direct full sun all day or at least the morning hours is the rule of thumb. In warm Gulf Coast states you have more flexibility with placement.
Is black available in the four chamber premium bat house ? I see dark green and khaki but no black. Thank you
We are sold out of black in that model and will not be making more. You can easily paint the other available colors black using a paint formulated for plastic if you'd like. We have refreshed the way the baffles are laid out internally and the newer 4 Chamber Universal is available in black. https://batmanagement.com/products/universal-four-chamber-premium-bat-house
Do you have a time frame when this product will be available in black? Thanks!
Hi- this item is replaced by the Universal 4 Chamber Bat House: https://batmanagement.com/products/universal-four-chamber-premium-bat-house
The older 4 chamber had all crevices at 3/4'', which was intended to target little brown bats. Unfortunately, "white nose syndrome" https://www.whitenosesyndrome.org has severly impacted this species. Therefore we have changed some of the crevice spacing to accomodate a wide range of bats, from all myotis to big brown bats and Mexican free tails. Of course, all these species are also known to use our older baffle configuration, we've just made it easier for them!
was going to order a dark green 4 chamber, check out said to check availability. Want to get bat home soon for new property. When are they available to ship. Like the idea of plastic.
We have a low number in green and will reprogram the website (green could be ordered with a pole mount if you want that as well). We completely sold out, look at the Universal 4 chamber bat house which is the same plastic shell but with an updated baffle cluster. https://batmanagement.com/products/universal-four-chamber-premium-bat-house
Im trying to purchase a BCM 4 chamber premium bat house and the color black is not available. Will green work for Northern Virginia with only 6hrs of direct sunlight? I live in a fairly wooded area that bats frequent, but the tall trees prevent full day sun. I'd like to install the bat house before spring arrives. Tom
Hi Tom I would stick with black for your situation. Black is available in the Universal Four Chamber Premium Bat House model https://batmanagement.com/products/universal-four-chamber-premium-bat-house . The Universal model has an updated baffle core. There are only a handful of green and khaki regular 4 chamber premiums left, and you can get them $20 off using coupon 4CHAMBER and simply paint them black with an outdoor paint formulated for plastic.
I was referred to you by Merlin. I'm wondering what color bat house you would recommend for central Florida (south facing)? I'm thinking of starting with your BCM four chamber premium model. The house will be mounted on a free standing pole, thus, no shade.Thanks!
Hello you may be in a transition zone between the dark and light bat house. I would probably start with the tan bat house and if there is no activity after a few seasons or temperatures suggest it is too cool, it can always be painted darker with paint formulated for outdoor plastic. (I have painted some plastic pipes in PA which still look good after 10 years.) But, mounting in sun it may work just fine as-is as tan. We would appreciate any followup you provide and can help with determining temperatures, etc. for you; email email@example.com Anyone else reading this who has not checked out Merlin Tuttle's Bat Conservation should do so; the website is a fantastic resource.
