BCM Bat Condo
QUESTIONS & ANSWERSAsk BCM a Question
Can I get plans for a bat condo? I have a contractor that will build it on my farm in the NE US.
A bat condo was really designed/intended for little brown bats, southeastern bats, and Mexican free tail bats. Unfortunately WNS has all but eliminated little brown bats from your area and Mexican free tails & southeasterns do not live in your area naturally. I cannot recommend a bat “condo” size structure for anywhere in the NE, unless there is a demonstrable colony of a significant size nearby. Bats today are better served by numerous, smaller structures. These have advantages over a single large structure, one being cost for sure, but there are other biological reasons. I offer 3 structures that are larger than a typical single bat house, but smaller than a bat “condo”. Depending on how many acres you have, you might consider a few installations to provide bats with a few options. The 3 structures are: https://batmanagement.com/products/super-duplex-bat-house https://batmanagement.com/products/modular-mini-bat-condo-2x2 and https://batmanagement.com/products/modular-mini-bat-condo-3x3 You would want to select the darker colors and the “northern roof” roof option for optimal solar heating. If you have the luxury of space, I would suggest one structure in full sun and another that is in full sun in the morning, then perhaps some shade in the afterno
I love the idea for the condo, and would love to possibly build one about half the size. Would it be reasonable to build in Virginia?
A scaled down 8' Bat Condo is a 4' Mini Condo. However we no longer recommend these large structures unless you have a very large colony you are mitigating for. Instead, consider multiple Super Rocket Roosts, 2x2 and 3x3 Modular Mini Condos. It is far better to provide multiple roosts in different locations and give the bats choices, rather than one large roost that is more vulnerable to predators/vandalism/natural disaters. Multiple smaller roosts are far easier to install and much less expensive than the large ones. In VA, we have lost the large colonies of little brown bats over the years, so those large roosts are usually only advised if you are in the range of Mexican free-tail or Southeastern bats (Gulf Coast states in general) We are available to assist with installations if desired, please write firstname.lastname@example.org
Hello, we would like to develop some bat habitats for an estimated 2000 Myotis type bats that are currently living in the roof our cabin. We would like to tie it into a study using condos made of different building materials ( redwood and cedar?)and data loggers/monitoring equipment to monitor conditions inside of the condos as well as the cabin roof. Is it possible to purchase the design plans so we can build our own Condos out of the different materials? Our goal is to partner with a local university and work with them to develop a long term study to help determine what works best and monitor the health and safety of our bat population.
Bat house materials were studied ~15-25 years ago when Bat Conservation International compiled data from bat houses across the country. I beleive it found no substansial differences from builting materials. Presently we recommend our Super Duplex bat house over a single large bat "condo" type structure. While it's true some bats do like to live together and some congregate into large groups, there are advantages to smaller structures. Smaller but multiple structures allows for predator and parasite avoidance. A Super Duplex can easily be expanded with 2 additional bat houses on the ends, offering space for close to 1000 bats. The posts are substansial enough to add even more structures under the bat houses creating 2 levels. Or, place a second Super Duplex elsewhere nearby to protect against storm damage, predeators, parasites, etc. The Super Duplex is significantly less expensive and easier to install than a Mini Condo and certainly a full side Condo. It is an attractive option to start with the base model Super Duplex and add additional modular roost boxes to it as needed, rather than a much larger investment of a Condo when unsure bats will occupy.
I am with the National Park Service at Fort Laramie. We are submitting a funds request for and new 8x8x8 Bat Condo to be installed in 2026. Can you give me and estimate on that installed cost? If you give me today's estimate I can add 4% increase for each year. The one you put i n herein about 1998 I think is working great and has lots of bats in the summer. We just want to make sure we have one here if something happens to that one. I suppose they get old and become unusable eventually. Thank you, Mike Evans Thank you
Hi Mike - I can quote that; but please email email@example.com as this Q & A feature is for general questions and we can't reply directly to individuals
Hi. We re in the process of setting up a 19 acre animal sanctuary in south florida. I’m interested in purchasing a bat condo for our property. Can you let me know availability and any other details? Many thanks in advance.
We do have designs we are rolling out that incorporate modular bat houses in clusters and banks. These are not available on our website yet. When bats are in small groups they may be more secure in smaller, individual compartments. These are easier and less expensive to install than any of the bat condo structures. There are 3 configurations: Small Modular Bat Condo: Single post support, back-to-back 4 chamber universal bat house, ~420 capacity Medium Modular Bat Condo: Double post support, four- 4 chamber universal bat houses, ~860 capacity Large Modular Bat Condo: Double post support, 6- 4 chamber universal bat houses, ~1260 capacity We also have these configurations using larger Bat Bunker bat houses with significantly increased capacity.
If you do not currently have a bat roost, you may want to start small. Because of the modular design, you can start with a smaller number of bat houses and add later, because the supports will already be there. For example, The Medium version can hold 4 bat houses, but you don’t necessarily need to put all of them on initially, saving some money. In addition, it is possible to add a lower row of bat houses to the Medium and Large supports, thereby possibly doubling the overall capacity someday if desired.
We have a small office in mid-FL and would be happy to work with you on this project and lend assistance. Please contact firstname.lastname@example.org for more info on how we may help.
Hi! My name is Trace, My husband I are located in the country on 50 acres of field, woods and marsh in the Ottawa Valley. I am wondering if the BCM Bat condo is something that can be used in our area (Ontario, Canada). We have mosquitos beyond mosquitos and we have a haskap farm that we will be opening to the public next year. I am a graphic designer and love how you are showing with info plaques and I would like to do the same. We are all about the environment and animal conservation and want to teach people when they visit our place. I look forward to hearing from you. Cheers, Trace
Hello Tracy - The 8x8 or 4x4 Condos with the closed bottom doors are suitable for northern latitudes and high elevations. You should start with smaller bat houses to be sure you can attract them, but if you already have bats in buildings nearby this would be fair game. We are also working with Merlin Tuttle developing a less expensive "mini bat condo" that addresses a few issues with similar structures and would be suitable all over North America.
