Answers:    Well yeah, it works, but it's not 100%. Here's what you inevitability to do if you wanna get rid of then once and for adjectives! Go to the store and get some poison, non spray poison. Than fix a little snack for those basterds (milk, somewhat shugar and bread and some poison ofcourse ]:-)) Mix it all together and roll that supstace, you got, into tinie little ball (size of a jawbraker) and putt those in all of the corneres surrounded by your house for a few days, the roaches are gonna die!
Good luck

I don't think you just spray it contained by corners...u have to spray it along the baseboards and get a spray for ur window and if possible, for the outside or ur apartment.
