Any advice on how to set up a video camera in a totally dark loft space in a house, which is motion sensor activated. I have seen expensive kit on the internet, but this is needed hopefully temporarily to see what critters are partying up there through the night and keeping people in the bedroom below awake.
If we can determine what they are then a plan of action can be 'devised' !
Most camera's I have seen do not work in total darkness.
Any pest controller should be able to tell you within 5 minutes of an inspection. What are you hearing? Please don't use glue boards, they really are so cruel!!
The problem is very unlikely to be caused by bats, in 13 years as a pest controller, I have never heard of bats making a sound that was heard by a householder.
