War against cockroach

Some sharing over here...

Cockroach that can fly are actually pregnant. According to a
documentary film, their ability to fly stem from a survival instincts
to protect their eggs while incubating. So it's a natural progression
of their ability when a female cockroach gets pregnant. So when you do see a flying cockroach, be sure to send it flying to heaven before it spills its evil spawns out!!!

To totally eliminate their race, after killing the pregnant cockroach,
use alcohol to burn it, so as to totally wipe out the eggs (remember
the movie Aliens, where Sigourney Weaver burns the eggs??) that's the only way to totally kill out these roaches.

Do not, I repeat, do not attempt to flush the dead cockroach down the toilet without burning it or totally squashing it! The eggs will still hatch and climb out to spread their evil around and you'll have more to deal with in time.

Also, do not use insecticide on the pregnant cockroach cos it will only help the eggs to develop resistance against the insecticide in future.
