Wrens are a definite pestilence. They get in through the floor vents when the fan is on and then destroy the place before I can run them out. I need to put hardware cloth over the vents but like every other non-critical thing, it keeps getting put off!

Since the majority of the roof does have shade cloth I don't see the roof vents as a make-or-break issue. What would be nice would be some way to screen them so the wrens stop flying in and trying to nest in summer. They become shut in overnight when the roof vents close, then start flying around at sun up, pooping on whatever they happen to be passing over at the time and pulling down the bubble wrap.. _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/… Unsubscribe: <mailto:pbs-unsubscribe@lists.pacificbulbsociety.net>
