Does a cockroach has any predators?

well considering how durable the cockroach can be that's a debatable question. it takes strong poisons and a variety of different gasses to kill the roach and meanwhile it isn't a vary quick technique....as for its survival there isn't to much to concern of considering how fast they multiply. however if the problem has truly or ever occurs humans defiantly would be they're match if they aren't ours. its probably best to keep colonies in specifically built nature preserves.
