Where do they come from?  I have about three in my apartment now, buzzing merrily about as they attempt to land on my food.  I thought I was imagining things at first - i know their lifespan is short and it's been below freezing for a couple months now.  But no indeed, there are definetly flies in my apartment.  I'd assume they come in on fruit or something but they don't look like exotic flies - I have an idea that kiwi fruit flies should look different from regular Canadian flies but I suppose they may not.

Now to begin the hunt for a fly-swatter in shops in Ontario in February... should be a great time.  The only really good thing being that shops seem to switch for the new season about 2 months before it is at all reasonable so I may have hope yet!  Perhaps I should just buy a ... flock?  herd?  ummm school?  of geckos from the pet shop and let them loose to eat my flies!
