My question is concerning your average everyday
housefly.Where do they go at night? They buzz around all day long, and
shortly before dark they disappear!I have a fly problem in my backyard,
and I thought that if I could "catch them napping" at night it would be
easier to get rid of them.
Houseflies respond to light as a rule. If the temperature is too low or
there is little or no light, they do not become active. They just land on
a surface and stay there.
