There is a way to get rid of them though. If you make a mixture that is half sugar and half baking soda and put it in their path, they will eat it. The Cockroaches cannot handle the baking soda once they drink water because they aren't able to expel gas. Their stomach literally explodes. Bam! Dead Roach! The best part is cockroaches are cannibals, so when they eat the dead, there is a trickle effect. If one dead cockroach feeds 3 live cockroaches, how long before a family of 10,000 cockroaches are gone if every hour, a new group of roaches are dying and providing food for the next group.
