I don't mind roaches, but that just plain isn't true of the species you commonly find as pests in homes. Ever swabbed a roach and tried growing the bacteria on it in a petri dish? We did this in one of my science classes in high school, as we were testing various items in the school for bacteria and happened to find and kill a roach.Cochroaces aren't actually filthy, they spent 25% of their time cleaning themselfes, it's what they can't clean of them selves that's the problem.
Most of the petri dishes, even the ones with samples taken from inside toilets and such, only had small colonies of bacterial growth after a 24 hour period... in the roach sample, many kinds of bacteria had completely taken over the dish to the point that the growth media had been sapped dry and cracked.
For the record, the only other thing that came even remotely close to comparing with the roach sample was air coming directly out of the overhead air duct. I wonder how long it had been since they cleaned the filters??
I think it's like they say, "cats aren't clean, they're just covered in cat spit"![]()
Externally, you might not have found much on the ones you had, which were most likely not caught in your house or in "the wild" but grown specifically for medical or experimenting on and were healthy. It's also internally where they carry all kinds of diseases and chemicals as well that is the real concern. Thanks to their adaptibility, they can withstand all kinds of nasty stuff and unfortunately, they do spread it to other places and organisms, including us.
