Have put new slim window fan in the study window. Not because it's *so* hot- is merely seasonable, which of course feels hot to those of us who've been living in November for the last month- but because the stupid mud daubers are back; or rather, mud dauber singular is back, and gets into crevices and makes its tinny mechanical sound I-can't-get-out!!!! So- stop up window, end of mud dauber.
No. Flits in between the unspinning blades of the thing.
