Artificial Refugium rule
(slrpnk.net)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
A friend of mine loves being in his backyard but hates the mosquitoes. He heard about this bat roost thing and installed one about 5 years ago. It has not attracted a single bat.
It's important to build the right kind of roost.
