I am about to start building my bat house using your kit. Should I sand the whole thing? I wasn’t sure if the inside surface should be left rough for the bats to cling on to it…or if I should sand the inside, too.
Sanding is really not needed but if you feel there are some sections that are a bit too rough, by all means go ahead and smooth them out. We do some basic sanding but by design leave them mostly as natural as possible.
At this time we’re not aware of any evidence to suggest that bats prefer rough over smooth and since we have make grooves throughout each chamber of our BAT HOUSE KIT, there will be plenty of areas for them to grab and hang onto securely.
