We just count it as a 'near miss'.

Perhaps an explanation is in order, Dr. Bill:

A gnat has no time for fear
The next "swat" is always so near
If he stops to exclaim
"I've survived yet again!"
The next "swat" is the last "swat" he'll hear.

A gnat just gets on with business
You might ask what business it is
Of his to make trouble
His efforts redoubled
But a gnat just gets on with business.
