Step 7: Adding the Door

Put the door inside the box, align it up so that its thickness is in the centre of the holes drilled in the side walls.
Get a Clout nail and hammer it in to make a pivot.

Tip: Don't bash the Clout nails in so far that it makes it hard for you to open the door.

Next you want to put in some doorstops, preferably they should fit tightly and run around the inside parameter of the door for weather proofing.
Just use glue as its a bit difficult to nail it in.

Finally with a scrap block of wood, drill a hole through it and use another Clout nail to hammer it near the top, this will be the door knob to stop the door from just falling open.
i think there may be a flaw in this design. the roof should overhang the back, instead of that vertical joint, allowing possible water penetration at that joint. you can always drill a hole for a hanging screw inside the box...one could wrap that area with some galvanised sheet metal, if you've already made it with the above config. bat's probably won't like it if it leaks...; ^)
Thanks richardsan for pointing out the potential design flaw.<br>I've checked to see if it leaks by spraying it down with a hose, it seems to be water tight probably because of all that glue I used.<br>-Grant
that wood is gonna expand and contract quite a bit...especially over time. if the glue is stable and unmovable and the wood swells and shrinks...just saying'...<br>all you'd have to do is erase that vertical line, extend that one angle line and adjust the 'how to' script and you'd have a better design by 100%...; ^)<br>
What is the finished size of the entrance slot (front to back, from the inside edge of the bottom of the door when closed, to the back board)? <br> <br>What is the door for? My bird houses have none. <br> <br>How do we interest bats in roosting in the box? <br> <br>--Terry
Hi Terry the entrance slot on mine is 16mm or 5/8 of an inch, but it can range from 15mm to 20mm (2cm).<br><br>I don't know why, but most of the bat boxes I've seen have had doors.<br><br>Bats here eat insects, so as long as you've got a good amount of insects in your garden your ok.<br>If you have a pond like I do it will probably be full of larvae that will hatch into hundreds of mosquitoes.<br><br>Another good option is to add a small light source outside the bat box that will attract flying bugs.<br><br>But as Gordyh suggested, rubbing bat faeces on the box is one of the best ways to get them to move in.<br><br>-Grant
To help the Bats find the house, find an existing bat roost and collect a handful of their droppings. Mix in some water and spread the mix thinly on the ladder. As mentioned in this instruct able bats have sensitive noses, they will smell the house and investigate. A friend tried this on one of the four roosts he built, and it was the first one the bats moved into.<br><br>Gordy

<p>IM SO EXCITED! We just bought a house on a small Lake. Trees, Herons, Ducks, but I want some Bats in my garden!</p>
I love that more bat boxes are sprouting up in the DIY world. My wife and I had bats in the attic of our CO home. While we loved having the bats around, having them in the attic meant that they were leaving droppings inside a living space, and we began to see dead bat bugs in the room directly beneath where they had entered.<br>We consulted a bat expert in the area, who was also an exterminator. Once we clarified that we did not want the bats exterminated, just not living in our attic, he said that he could help us seal the space up and create a one way egress for them to leave but not be able to reenter. In order to keep the bats around, I built a bat box to sit at the peak of the eave and blend with the existing facia (our HOA has very strict rules about external appearance. I decided I'd make the box blend in and not tell anyone. Probably better to discuss it with your HOA first. In the end, it turned out ok once they found out about it, but YMMV), and had to paint it to acheive this. While bats may have sensitive noses, they also want a warm place to roost. If you feel the need to paint your bat box, take it from me, it will likely turn out to still be a welcoming place. Mind, though, it may take longer for them to decide to live there.
<p>In some colder or warmer climates it is advised to paint the bat box darker for heat absorption or lighter for heat reflection, but it has to be a paint that will not interfere with the bats (obviously). But sometimes painting is needed. </p>
i live in the Us in Mn any major changes i would have to make? we get mostly &quot;little brown bats&quot;, pretty sure we are dealing with the same genus.
where can one purchase bats from? there are no bats where i live in the city.
You can buy a bat from<br> <a href="http://www.amazon.com/Folkmanis-2391-Brown-Bat-Puppet/dp/B0007QO3SW/ref=pd_sim_t_1">Here</a> or <a href="http://www.amazon.com/Louisville-Slugger-MLB225YB-Baseball-30-Inch/dp/B001Q3LELY/ref=sr_1_1?s=toys-and-games&ie=UTF8&qid=1307209928&sr=1-1">Here</a><br> <br> I don't know much about laws in the US.<br> But if you really want a pet bat, my advise would be to have a look around Google and <a href="http://welcometointernet.org/">The Internet</a>, and happy hunting!<br>
Kudos to your mom for wanting to help bats. This instructable is awesome :) I couldn't build something to save my life, but think it is great.
If you are itching to decorate the bat box, you could do wood-burning. :)
Wood burning does sound like an interesting idea, but apparently you can use paints such as black to regulate the temperature.<br>Another idea I would like to try is carving, sticking bark on to the box to make it blend into a tree sounds good but may prove harder for them to find.<br>-Grant
The guide is adamant about keeping it paint-free, though, which is why I suggested it. I wish we got bats in California (well, we do, just not where I live).
Nice work. I've always loved bats. They really are amazing creatures.<br>Have you got any moved in to your box yet? I guess you might need to wait a long time before any bats realise the box is there and ready for them?
I don't think any have moved in yet, but there was one flying around my head near to where we put the box, the other night whilst I was using my telescope.<br>-Grant

What's to stop bees or wasps from making a home out of this before the bats can?<br><br>I like the idea of having a bat roost around, but not as much as a I dislike the idea of having to deal with wasps.
I have always wanted to have a bat house in my garden. I wonder if the bats can find it though. The idea of finding another bat roost and securing some guano sounds good, but I have no idea how to find such a thing. I am in Southern California and I see bats at night sometimes. Will do some research and check back. Thanks for the Instructable. I do think that the design of the top might not be watertight though.
The house should be on a tall pole and in the open.
I'm not one to spoil anyone's fun, but I read somewhere that despite determined efforts over a number of years here in the UK, there was no evidence that bats had ever used an urban bat box.<br><br>In the true spirit of instructables, get out there and prove them wrong!!
Could you convert the measurements to english as well? Thanx,
I've been told it needs to be on a south-facing wall to keep them warm in the winter. <br>
Looks great!
