what are the likely causes of flies..? not fruit flies, big annoying flies.
this week we’re finding multiple flies a day inside, no windows are open, its freezing..
tried sniffing around every room and i cant find anything that appears to be rotting, bins are kept in the garage
.. my first thought is drains?
Cluster flies like to just be there - they hibernate inside in winter.
