Carrots have a better nutritional value for roaches or people. I happen to like the jicama added to salads and whatnot, but the price for me is more expensive than carrots, so for less nutritional value I see no point.ive read from a hisser keeper that her hissers bypas carrots for this..http://en.wikipedia.org/wiki/J%C3%ADcama anybody ever try this with there roaches?
