Since we couldn’t do anything drastic (like sealing up holes) until babies are able to fly around August 15th, we decided to get a start on another project that wouldn’t negatively affect them. The second step was to build bat houses to attract them into relocating.
My brother, getting wind about our dilemma, offered his assistance in building bat houses, since he helped a friend in the past. The boyfriend went ahead and put his mounds of scrap wood to use and slightly modified versions of these two plans here and here.

They also have chambers inside; you can sort of see them in the above photo.

The boyfriend decided to have the bat houses near one of their main entry points on the side of the house up high in our tree:

The other two were installed in our monster tree:
So far, the houses haven’t attracted the bats but according to Batcon, 90% of bat houses are used within the first two years. Sometimes they can take three to five years to find their new home. Although, that same resource also mentioned trees are not good locations since their predators are nearby. So I kindly asked the boyfriend to think of an alternative location, say our garden this year (so the guano can act as fertilizer). His concerns are around where we would find a suitable pole.
