Okay, so I seriously hate cockroach. I saw one with wings crawling on my living room wall, so i sprayed using mosquito spray. I guess it doesnt work that well cos it was still running all over. So i sprayed some more until it turned on its back. Worse, its crispy legs started wriggling for so long and i begin to think that the mosquito spray is useless. Not the right spray I guess, need the specific "just for cockroach spray". Then i suddenly saw my EYeMo drops on the table and press like 4 drops on it. Instantly it struggled for its last breath and pass away on the spot. Wah, this eyemo damn Powerful leh. So I checked what ingredient inside, Boric acid. So i did internet search and found out it could actually kill Cockroaches!! Haha, how convenient and strange right!!!
more likely the insecticide took some time to work and all the eye mo did was to drown the roach....
Insecticide also contains boric acid, it is a substance present in most insecticides, and antiseptics.
And I believe the roach was at its last breath when you coincidently saw your eye mo.
For me, hot water from the flask is instant kill, no oily residue when the water dries up somemore. Just make sure you are a headshot honcho like me.
