Love that! I've figured out that it's near impossible to swat a stationary fly unless you sneak up behind
them -- otherwise they'll spot you and they're gone.
And this thread reminded me of the last time I visited my mom about a week ago; she had a few flies in the house and she told me my sister (who also lives in the house) THREW AWAY my mom's perfectly good flyswatter!!
According to my mom, she said something like, "What do you need a flyswatter for, anyway?"
