Earworm: Scars~~Papa ROACH

AUGGHHHHHHHHH i can't believe i found a cockroach in my room for two consecutive days!
yesterday, when i saw it, and it was freaking huge, then i freaked out naturally even though i killed one by myself last sem. i had to call LH for help even though he's afraid of cockroaches( i thought flying ones only ma) so he squashed the bug for me.(thanks!=) He blamed it on my room being too dusty and cluttered so cockroach like to hide there. and i was like then the cockroach go into each person's room to look see the conditions la.. whatever it is, i cleaned like mad. first time i mopped my floor in a long time (normally i borrow his vacuum cleaner ok!) and cleared most stuff on the floor except for my guitar, storage box and luggage bags.
Today afternoon, i even changed my bedsheet and filed away notes lying around.
after coming back from dance and WHAT DO I SEE?????
ANOTHER FREAKING VERMIN
FROM THE BOWELS OF THE EARTH!!!

Really cannot tahan! this time it was instant death for the roach. Went to take the bug spray and let it have the full blast. that's right go crawl to my luggage(EEEE...) and die!

WHERE THE HELL IN MY ROOM IS THERE PLACE FOR A ROACH NEST!

waste my night only doing additional cleaning and clearing of junk, even though they're stowed away in cupboards. and also sealing my door so the dratted insect cannot crawl in. i sure hope they don't fly in from my window. Paranoid already la. I'll have nightmares of cockroach nests!
