Cockcroach Population Controller

Personally, I think that Philippines country is infested by tons of roaches, I killed average one cockcroach per day staying in here. I saw cockroaches in our 21st floor office, my apartment. And guess what, our customer's office too. The funny thing is, during our meeting with our client in another building, I saw a cockroach crawling on the wall, first time I saw that, aren't they suppose to have somekind of pest control on a certain period of time? FYI, KLCC did that. My policy to cockroach is - NO MERCY to this kind of pest! Lucky thing is, their cockcroach size is not as big as Malaysia, if all of their size is at least 7cm, then it will scare the shit out of me.
