Houseflies-- every late Sept. to early Oct
our 18th floor, West exposure apartment swarms with houseflies in the
window (9 ft from floor). We remove approx. 20-30/day with a vacuum cleaner.
The drapes are new, the house is clean. There is no food/liquid where
Why are they coming? (How, other than screening the
apartment, do I discourage them?) The temp. is higher than 25 C long
before this becomes a problem. I live in Vanc. BC. Please advise.
Dometicus horribilus will hatch in the remains of almost any organic matter
that will allow their sustenance. They bloom during periods of warmth after
stretches of cold.
You must check any area they can breed. This includes houseplant soil and
and cracks in woodwork, especially where water might be available. Over the
short term, once any habitat or potential food are removed, the flies will
quickly cease to live in the area.
