Bats Roosting in my porch: 4. Success with early morning arrivals

on 11th July 2014

The last post on efforts to discourage roosting of the Common Fruit Bat (Cynopterus brachyotis) in my porch saw partial success LINK. A pair of powerful spotlights was directed towards where the bats normally roost. In addition, 28 Compact Discs (CDs) were placed on the ground below the roosting area with the shiny surfaces facing up. The bats arrived between 1930-2030 hours and roosted on the roof. Only when efforts were made to cause reflections on the discs did the bats flew off.

This post describes efforts to deal with bats arriving during the early hours of the morning, between 0530-0630 hours. Unlike the late evening arrivals, the lights and CDs had a positive effect on the arriving bats at this period. As can be seen in the above video, they flew in one by one and immediately flew out, never roosting on the roof of the porch. The fact that there were no stains on the ground showed that they did not return after the spotlights were switched off. It has been a few weeks since and the bats have yet to roost in the porch during this period, even after the lights were not used.
