Typically old pallets have been set down and slid every where. They can be
loaded with small rocks and sand. Don't send it through your jointer or
planer. Nails and staples are only 1/3 of your worries.
Thanks for the warning. But for these critters, they want a rough
surface to cling to. Will likely join the edges with tongue and grove
approach done on a TS. Fancy is not needed. Still doing research on proper
dimensions for the bats near me. Seems there are two type of bat houses in
general. One for the males and a larger one for the females with young. The
highest criteria seems to be light tight with very rough interiors.
BTW We have LOTS of mosquitoes her on Long Island, but not enough bats

Sounds like a great place to use a belt sander and 24 grit belts.
Used this approach extensively to prep plywood before laminating knitted
fiberglass and epoxy to the plywood.
BTW, 24 grit eats nails and other stuff you may find in pallet material.

As Long Island bats reach a certain age, they migrate in large numbers
southward along the Atlantic coast toward a region in Florida bounded
on the north by Ft Lauderdale and on the south by Miami. I understand
that in their pre-migration stage, they tend to develop bluish hair
and fat ankles...
...while the mosquitos, lacking migratory instincts and the robustness
required for extended flight, remain behind.

So cedar is the recommended wood, as your pallets will not last too long.
Last year I built a dozen bat houses out of recycled (ie. found in the
trash) cedar, but never got around to using them when I found out they had
to be put on poles! Bats will not nest in boxes put on houses or trees.
I used an angle grinder to roughen the wood.
Naturally you can't attract the bats to someplace they wouldn't ordinarily
live, so if you don't have bats now, they may not go for your houses.
I have just built a couple out of cedar and was going to attach them
to trees untill I read the above. I thought trees were okay if it was
open around the tree and lower limbs are cut off. I need a site that
talks about whats needed such as height etc.Any recommendations?
The important spec is temperature. The bats like it quite warm. A
position that gets morning sun to give a quick warm up after cooling
down all night is most ideal. Thats why trees arent recommended,
their branches shield the house from the sun, limiting the inside
At northern latitudes its recommended the house be painted black, to
maximize solar gain, at mid latitudes, a neutral color is recommended
and at southern latitudes, the house may even need to be painted white
to keep from over heating.
The recommended height is 15 to 20 ft.
Now having said all this, 6 years ago I built a bat house, insulated
it, put it on a utility pole facing south, painted black, 20 ft up,
and I've never had a bat move in, just wasps.

While your bats are a bit different than what we have in Washington
(the state, not the "state of mind"), see if some of the information
is of help: http://www.batsnorthwest.org /
We built a bunch of the "rocket box" houses - I used a 8 foot cedar
4*4 (rough) for the top section and then a 12 foot pressure treated
for the lower section, bolting the two sections together with an 18"
overlap. Makes it easier to transport, more resistant to rot at the
bottom and cheaper. The "Rocket Box" houses are detailed here:
We have not had a chance to get back and check out the 5 we put
up out at the Girl Scout camp (it was my daughters project) but we
hope they moved in - they had sealed up the old barn the 400 or so
bats had been using for years after parents complained about babies
falling on the kids during a meeting in the barn.
What accumulates under the bathouse is called guano, and is fairly abundant.
Keep at a distance from small children and clean up once in a while.
Strange how we get our knickers twisted over insecticide when more dangerous
stuff is right under our noses....
Recent window replacement require the removal of a few siding boards
which exposed several very unhappy bats. They had crawled in at some
point above and made it several feet down under the siding. I left them
alone and they made their way, slowly, to cover. I installed a deluxe
bat-house when the window project was finished. Point is, if they nest
_in_ my house, I think it'll be okay to put the bat-house _on_ my house.
Lots of bat and bat-house links with design considerations and free
plans. Bats are good* and giving them a proper home may help keep them
out of your attic (hey, they're good but I don't want them in my house)
*I hate mosquitoes.
