I can't believe I'm the first person to think about this problem- what

(Obviously not using PIRs is an option but the idea of wires etc to
window / door sensors really isn't practical. A few PIRs will 'cover'
the required rooms and I think there are routes for wiring, if we can't
find a wireless solution.)


A few months ago I asked about using PIRs with purrs (sorry, I couldn't
resist) and was told that the "pet proof" ones were not very effective.

We had one fitted in our garage in an attempt to reduce false triggering
due to bats.

It didn't work.

But then, the bats aren't pets.


Well get rid of them then and say nothing. It's not like they are going
to fly off and report you.

No 4 of this looks a bit dodgy

So if you find a dead bat on the floor you are not allowed to keep it?

Maybe not but the penalties for doing so are not to be underestimated
and bat colonies tend to be 'known' to local enthusiasts. We discovered
this while on holiday some years back and noticed some bats while
walking back from the pub one night. We stopped and watched them,
thinking we were alone and then had the feeling we were being watched.
Tucked away in the gap in the hedge there were a group we'd seen in the
pub. They had 'bat detectors', note books, flasks of coffee..... They
went round all the local roosts (or want even the places bats hang out
are called) at weekends, and spent Sat night watching and listening to
them. Beats late night TV, at least in Wales. ;-) (Only joking, the
place we were staying was really nice.)

I believe you can ask 'experts' to move them - they re-site them rather
than just kill or exclude them- plus handling bats can be tricky, they
can carry a disease similar to rabies.
