A fly has like a bazillion eyes and is generally the most annoying and still the fastest pest to evade capture.
I am faster than a fly.
So long as they’re sitting waiting on food or bench-tops, I can take the fly swatter (most ingenious household invention) and swat them in the first go. This usually maims them enough to disable flight.
I then proceed to swat them again, OR grab them in a kleenex and dump them in the bin.
Ha! And people think Superman is fast.
