It sounds like you are infected with a very expensive disease I call the "hardly waits".How do I know? 

I swear I saw the roaches litterly attack the bait and the product goes a long way. if the place is vacant, leave the dead roaches and the live ones will eat the infected dead, expediting the process. seems to work for camel crickets too I've just tried this stuff for a small roach problem and haven't spotted one since. as others advise, clean and get rid of food source.

Talk about being infected with terminal entitlement disease!

Starts with setting up plastic containment around mold infected area, negative air HEPA filters, drywall and insulation removal, literally scrubbing studs with wire brushes, and treating with chemicals.

@Joel Florek the living people are the ones you need to be concerned about infecting you; no special cleanup is necessary, there may be a small amount of discharge (urine/feces) after someone passes.

Cut the losses and move on before the wound gets infected.

You wouldn't know what they're infected with.
