QUESTIONS & ANSWERSAsk BCM a Question
What is a "pup catcher" and what does is do?
A pup catcher is a screen and ledge installed under a bat house to help prevent pups from falling onto the ground. One main reason we think pups fall out of a bat house is it becomes overheated adults crowd them out. This is mitigated by using a BCM bat house with a rear vent (all of them have this feature) and installing with the mounts so that the vent is kept open. The mount method also creates a "cooling off" space behind the bat house. With these features we don't think a pup catcher is necessary, and may actually offer a perch for predators. Some biologists beleive pups out of the box have little chance and there is some other issue that a pup catcher would not correct anyway. We would only suggest one if there is a chronic problem with pups falling out of a bat house, it is not something to install on every bat house everywhere.
Just an aside, Our Rocket Roost and Super Rocket Roost incorporates a number of "wedge" crevices that is harder for pups to fall out of.
Hi, would you all be able to site surveys and suggest placement (for a fee) from photos or google earth maps ? I plan to install a bat house I had built on my property. My long term goal is to educate our community about bat houses to reduce the chemical spraying here in Sarasota county, FL. Thank you, Timothy
Hello Tim- if you'd like a quick desktop survey and suggestion just send a Google Earth polygon of your project area/property to email@example.com
Do you know of a company who will install a bat house in Holmdel, NJ 07733 at my residence ? I read that you will travel that distant at significant cost. Do you know of someone closer ?
Hello Dan- We can help you out; the cost of that install would be $349+$182 for the travel, $531 total not including the actual bat house. The mount kit and post is included. I can offer 10% off for any install scheduled until New Years. Please email firstname.lastname@example.org for a firm quote. Thank you!
Do you place bat houses near Shelton, CT
We will install bat houses almost anywhere however schedules may require a bit of a wait. There would be an increased cost the further from Carlisle, PA we get. Feel free to request a quote here: https://batmanagement.com/products/installation
Hi. Where are you located?
Carlisle, Pennsylvania and Englewood, Florida. Sometimes everywhere in-between or so it seems.
Hi! I changed my negative response from, "I'd rather not drill holes in the bat house to solve the overheat problem," to embrace your idea of drilling holes in the bat houses to cool them. We also painted the bat houses white to reflect the sun. It's mid-June now, very hot. I have seen zero baby pups on the ground! Success!! Drilling vent holes worked!! brilliant idea!! Thank you so much for that solution!!
Thanks - it is much easier to solve an overheating problem than if the bat house never gets hot enough in the first place. You might consider a second bat house on the backside of the first one.
We live in a very treed area, and were thinking about installing our bat box on our house, and it seems like the chimney is the best for the criteria you laid out in your article about choosing the right site for the installation. Anything wrong with doing that? It's southeast facing, gets the most sunlight of the yard, and isn't shaded by trees.
Hi- please see our resource "Mounting on post vs. building" located here https://batmanagement.com/blogs/bat-roosts . Basically, bats will splatter the chimney with some guano, and a small pile will form under the bat house, so you don't want that say right over a sidewalik.
Hello, I am located in Virginia Beach, VA and have a home situated on one of the back bay tributaries (brackish water). I have seen a bat our two flying around our 2 acre property and am interested in attracting more to combat our mosquito problem. I have been looking at the rocket model as I believe it would hold up better against the elements and higher winds generated from frequent storms moving through our area. The current plan is to erect it at the bottom of our yard out in the open along the water. This location is well away from any trees and receives sunlight the majority of the day. My concern is that the tower will overheat and drive away any potential residents? Also, I also read that a dark gray color is best for temperature regulation in this area but didn't see any color options? Would you please provide any additional recommendations you may have to inform a decision (i.e. color, venting, other models etc)? Thank you.
Hello- The Super Rocket Roost is very tall and by the time the bottom is reached, temperatures are approximately equal to ambient in our tests. This model has a wide range of internal temperatures. It is a little more intended for more solitary bats as opposed to big showy colonies of 1000, etc. We only offer one color because we beleive the vertical extent of these creates a good temperature gradient.
Do you know of anyone who will do bat house installation in Arkansas? I am having a very difficult time finding anyone here.
Hello - Probably be best to get all the materials together in one place and then have a handyman stop by and put it up for you. Two or three people can flip the pole upright into the hole, and it is easier using a pickup truck with a ladder rack. If you are interested in a larger structure like our Duplex house, I can quote to install something like that.
I recommend a 4''x6'' x 16' treated post, it should be $50 or less from a local lumber yard (Lowes/Home Depot doesn't carry that length). Add a post protector to extend the life of the post. https://batmanagement.com/products/post-protector-4-in-x-6-in-x-42-in Also at the lumber yard will be 60 lb bags of concrete mix for $4 a bag, you may want 2 bags. A 3' deep hole that isn't much bigger than the post will use all the concrete, if the hole is a little big, add a few rocks. More info installing is in our manual with the bat houses and also in our learning center: https://batmanagement.com/blogs/bat-roosts and also some videos: https://batmanagement.com/pages/video-bat-house-how-tos
I'd rather not drill holes in the bat house to solve the overheat problem. I was thinking of a temporary fix using heavy duty reflective tin foil and foil tape just on the front of the bat houses that would reflect the overly hot sun during May, June and July. The foil may be enough to lower the temperature even 5 degrees could help them. After that it can come off. What do you think? I would wait until March to do that. Thank you for your advise.
That would work, but may become a drag installing and removing it every year. Holes or slots cut into the front & back of the bat house 1/3 up from the bottom is more of a long term fix, but also consider installing a second bat house nearby in a more shaded location and bats will move between them thru the year. If you are in a Gulf Coast or desert area consider a shade roof something like this: https://batmanagement.com/products/bcm-modular-bat-house
I just moved to Luray VA 22835. I successfully excluded a large colony of big browns 11 years ago, before I began my home renovation so the colony of bats moved into two back to back bat houses I provided. Problem with a pup catcher is the houses are on a 21' tall metal pole. How can a pup catcher get installed on a metal pole?, the basket would be unsupported. If I could find where to buy the mesh, I could make something to staple to the bat houses.
Hello - you could find an appropriate sized U bolt from a hardware store that fits around the metal pole, then the lower basket would be attached to that or a wood spacer. The pup catcher should only be installed if there is a problem; otherwise it makes an attractive predator perch. Problems with pups falling out typically are from overheating; you might consider drilling numerous vents 1/3 up from the bottom around the bat house to improve airflow.
I live in Reston, VA. I'm interested in a bat house and installation - but I'd prefer mounting to the side of my house rather than a pole. Can someone please advise?
Hi - Check out our Resources and Free Advice link at the top of our pages. In the Bat Roosts section, the pertiant articles are How to Mount on Stonework and Mounting on Buildings vs. Posts. Email us if you have more questions.
How many houses would you recommend on a 20 acre property?
Hello I would start out with a few bat houses in different locations, possibly even a mixture of Super Rocket Roosts and 4 Chamber Universal bat houses. This gives bats a variety of option and essentially lets the local bats reveal their needs to you.
Hello, If I can find some neighbors who also want bat houses installed, can we split the travel cost? I live in Greenbelt MD, which is just around 100 miles away . Thanks for thinking with me!
Yes, unless we are unable to install all of them in a day. We should be able to install 3, perhaps 4 a day, especially if the soil is easy digging!
Hello, we are interested in purchasing a bat house from your company and also potentially in having it installed. We live approximately 120 miles from Carlisle, PA in Manassas, VA. Would we be able to get installation services from BCM given that we are just outside the 100 mile radius? If not, are there any companies in our area that you would recommend for installation? We would like to get professional advice as to the best position on our property to install our house. Thank you for your help.
Hello- we will install bat houses at your location no problem. Ideally you want a location that receives all day direct sunlight if possible, or at least 6 hours or more of morning sun. Feel free to request a quote for installation email email@example.com
Hi -- I am in Allentown, PA. I am sure I have bats near my house. Years ago, I got a bat house (hanging on my front porch, where I see bats), but I've never seen a bat in it. It could be a bad design AND/OR a bad location. I would love to have some working bat houses on my property, whether attached to the house, or on poles. I know there are different kinds of bats, so that also might be a variable in what kind of success rate there is. If there is a good chance of helping bats, I'd be willing to try it.
See our resources on bat houses here: https://batmanagement.com/blogs/bat-roosts as one article specifically deals with why bat houses fail. You might be able to refurbish the one you have (caulk around the roof, paint it black, rehang in a very sunny location, scratch up the landing pad and any baffles you can reach).
The Super Rocket Roost https://batmanagement.com/products/bcm-super-rocket-roost
and the Universal 4 Chamber https://batmanagement.com/products/universal-four-chamber-premium-bat-house both have a variety of crevice types that would be attractive to big brown and little brown bats in your area. Either should be placed in full all day sun in your area if possible.
