    Norbert, that’s a nice, fresh layout. “Diseases obtain,” should read, “Diseases obtained,”

    I cringed at this information because I left a glass of red wine on the balcony table this week – the next morning there were hugh bugs drowining in it. Roaches love a drop of red! j

    Well, Madagasgar roaches are kewl. They are more disease-free than other roaches and actually make nice (albeit unusual) pets. I used to raise these as food supplements for my Bearded Dragon lizards. Maddies are only shipped to certain states in the U.S., some states, either gender can be received. Other states (warm, southern states like Florida maybe?) can only receive MALE madagasgar hissing roaches, lest the female escape and lay eggs. -Invasive specie concerns, etc. Some warmer states prohibit Maddie altogether.

    Anyway, they can be a commodity too, for pet shops and some scientific labs from time to time require Maddies, and they pay up to around $5.00 EACH for these roaches.
    I always cringe when in a movie they use a Madagasgar hissing cockroach when they infer a ‘other’ type of roach.. you know, -like “MEN IN BLACK” has Will Smith kick a garbage dumster and 1000s of Maddies spilled out… that will NEVER, EVER happen and the suspension of disbelief just died for me right there.

    And that “Next Karate Kid” kid movie with Hilary Swank. She was in a Monastary in California and a Maddie ran acoss the table and she tried to hit it with her shoe… again, NEVER gonna happen as Maddies don’t live in California! But then again, I’m rather a stickler for the facts I cling to… one small technical err like this and for me, the movie is no longer ‘believable.’

    Kewl article, fun!
