The "Brutzler" under Swat ^^

No more stains on the wall, neither black nor red: -D
With the things of the plague within minutes of finishing off is made.
50 "in one go" in under 10 minutes, could not be better.
Often enough, a little touch and the Fly says goodbye with a loud bang.
When flying you should but keep the button pressed until it crackles better, otherwise the beasts often recover again, wasps provide faster, are dead after the first contact in any case.
