I’ve seen a few bat houses posted here lately, so I thought I’d post my bat house, completed in July of last year. This bat house is described as a rocket box. It is designed to slide over a post. There are three concentric sleeves which form the roosting area. The inner two sleeves are made of cedar. The outer-most sleeve is made of poplar painted brown.

The innermost sleeve has horizontal saw kerfs cut a quarter of an inch deep to give the bats a surface to cling to. The rest of the vertical surfaces have plastic netting attached. The netting used is pet safe netting used to rescreen you screen doors and windows.

It was mounted by sinking an 8 foot 4×6 PT post into the ground 4 feet. A notch was cut in the 4×6 to receive a 4×4 post. The 4×4 is used to hold the bat house about 12 feet in the air.

While I am not an expert on bat houses (mine has remained unoccupied thus far), I have done quite a bit of reading. The plans I used were obtained from a publication called “The Bat House Builder’s Handbook”. This is available from Bat Conservation International (www.batcon.org)

Another good site with a wealth of information is the Bat House Forum (http://www.bathouseforum.org/forum/).

Not all bat houses and bat house plans are created equal, nor are all finish choices good. The placement of your bathouse is also critical (I don’t think I have placed mine well…too much shade). The above two sites will provide a lot of info to steer the bat house builder in the right direction.

Hi Rick:
batcon.org is where I got the original plan for my Bat House, that you made a very valid comment on. The Plan is no longer there, you have to buy the book…LOL…I also had a look at a number of other sites to get all the info I could. One thing that most of them mentioned was to NOT use ANY kind of material that gives off any kind of an Odour that they will Detect. Certainly not anything that has been found to be Toxic in any way. They state that All interior surfaces of the Bat House should be coated in a SAFE, Dark, Water Based Paint as a Sealer.

It is NOT an easy procedure to get the Bats to occupy a Bat House. By their very nature they are VERY sensitive and will not come close to a Habitat that is not as Natural (Nature) as possibble.

I offer the following in a “Positive” way, NOT as a “Criticism” of your efforts. I took note of the products you have used to construct your Bat House.

I’m not sure about the United States, but in Canada the use of “Pressure Treated Lumber” and the Chemicals used in it, have come under a LOT of scrutiny and are VERY tightly Regulated!! The Government will no longer accept it for use IN, or Exposed to Water, i.e. Docks and other locations, or Inside any Habitabal Structure. It “Gases Off” and “Leaches” into the water and it DOES kill the Fish and other Aquatic Life.

Cedar is an “Aromatic Wood” whether it’s “Named” that or not. In fact I have Contractor Friend who Finally (2 YEARS??) found out why he was suffering a variety of “Not Nice” reactions and illness’es. YEP! He loved to build Cedar Decks on the Homes he built. Now he CAN’T even go near Cedar, it’s just gotten worse.

My Bat House was built from 1/2” Poplar Ply and White Pine. I didn’t want to take a chance exposing the Underlying layers Of Plywood by “Scoring” the surface and exposing whatever type of Glue/Chemicals, they use to Laminate it with. So the interior was well sealed, then as you could see I used 1/4” Screening Mesh for the interior and the “Landing Surface” just below the entrance.

I’m also pleased to report that the Bats seemed to Agree with the “Batty Experts”!! It is well Occupied, much to my “Other Neighbours” displeasure. “YEAH”!!! OOPS! Guess I shouldn’t have said that. Or NOT!

Once again this is meant in a TOTALLY Constructive way from a Fellow LJ to yourself and other LJ’ers who might find it of some value.

Rick (The other one) ;-}

I too have built a number of bat houses. Well really I helped my father do it for many years. To this day I think that there has never been a resident in any of his. One tip that I did pick up was to paint a “hole” in the front and install a little “perch” just below it. This makes the box look like a birdhouse which has accomplished two things.

1. The kids leave it alone because they would throw stones to see if any bats came out of a “bat house”.
2. The nosy neighbors would not ask questions about it which would lead to fears, and in one case, accusations that the family was responsible for the spread of rabies. (ignorant neighbor)

Side note for these HAM Radio operators in the group. The “fake birdhouse” trick would work to cover up electrical equipment, monitors, gadgets and on. This all but eliminated the neighbors complaining about the equipment “messing up” their TV reception. (Again, ignorance)

Thanks for the comments all. I have two houses I build several years ago and never put up. I used water based paint and screening too. I’ll have to take the time to put them up and see what happens. I was really surprised to see how much material each multiple layered house required. Thanks again for the reminder to pull out the houses. BTKS

Wow that’s cool. I’ve always wanted to build one of those. There are several bats that roost somewhere on my property and it’s neat watching them at dusk feeding. Bat Conservation International is a great site if you’re interested in anything bat related.

Have your say...
