50% of Australia's insectiverous bats roost in tree hollows. As their name
implies, they eat only insects, including mosquitoes and crop pests, and so deserve a lot
more attention than they are getting.
There are many accounts of these animals using batboxes, but the
results are very variable.
Little work has been done in Australia on
the factors that determine why bats will use some boxes very quickly and others not at all.
However, there is now enough material to hypothesise on some of
these.
1.
Many Australian researchers have reported that bats frequently show a
high allegiance to an area but not to a particular roost. Further,
research with batboxes at Organ Pipes
National Park has revealed that maternity colonies there relocate
nightly between roosts. All of which suggests that batboxes would
do better if installed in clusters rather than singly.
2.
Nestbox shape and size appear not be be significant. The sketch below
illustrates the designs that we have trialled, most of which have been
successful, albeit in low numbers.

3.
Batboxes often have a problem with ants, but Monika Rhodes' work
indicates that it is the floor in a batbox which encourages ants - it
gives them something on which to lay their eggs. If true, moving
to the American model of batbox, where there is no floor, should
remove the only pest to which batboxes are susceptable.
Please enquire if you are interested in
batboxes. We are constantly changing our batbox designs and are
not yet in a position to offer one that is absolutely proven.
Nevertheless we are willing to discuss what we have to
offer.
We would particularly like to hear from anyone who has had consistent
successes with batboxes. |
