I get these too, and have always assumed them to be a sort of
spring-tail as mine are always bouncing about:-) I think it's the
little clear worms that pupate into the small black flies but I'm
no entomologist (but I was a pesticide application specialist in my
last incarnation:-)). Either way, a good whiff of insecticide clears
them for a while if necessary but my Pings do a good job too.

Probably because this is water based. Most pressurised cans have
various solvents instead. It's rather wasteful to spray to run-off
though - save money (and cut-down on the environmental polution)
by giving half as much (or less?).
