Florida has things called Palmetto Beetles that which is a euphemism for really nasty big flying roach. The way to kill them is to put out containers of sugar mixed with borax, they love to eat it, and it suffocates them. Stick it where your pets or kids can't get it, under the refrigerator, back of a shelf, and rather quickly, no more roaches. It also works on little roaches as well.
Finally, a good use for refined white sugar!
