If you want to Kill a Cockroach with your slippers the first thing to Understand is Cockroaches have a Brain and can think like humans.
When you Strike it is either you hit the Cockroach or the Cockroach moves and escapes, as the Cockroach escapes it will become afraid and this fear makes the Cockroach indecisive , the Cockroach will not move quickly after the first duck, you can then strike again and kill it.
The mistake people make in Killing cockroaches is thinking they cannot miss so when they miss they become paralysed since plan A Failed. To Kill a Cockroach you must have a Plan B, once there is a plan B the Cockroach is as Good as Dead.
Cockroaches in The World.
All those Cockroaches who like Cockroaches eating the Produce of Farm Lands.
