We should point out that bat's are legally protected and therefore it is illegal to disturb bats in their roosts. In the UK and Ireland (Europe), only licensed bat workers/ecologists are permitted to physically inspect roosts including bat boxes. As it happens, Chris has such a license and so is able to inspect the boxes as necessary. It is still possible to monitor if a bat roost or box is being used through non-invasive ground based methods which basically means watching the entry/exit point for bats as they emerge or (re)enter. Having an ultrasonic detector in hand helps with species identification.
