Seriously? You people live with vermin? Geeze. I cannot suffer a bug of any kind to live in my house and I live in the woods. That lovely butterfly? Perfectly safe outside. Outside.
What about crickets? Nothing more innocuous than a cricket...
When I lived in New Orleans there wuz cockroaches. Everybody had 'em. Palmetto Bugs technically -- they can fly a short ways. But we also had gekkos that hunt them, which is kinda neat to watch.
Here in Carolina I have yet to see a cockroach ever. When I do see something that looks like one it always turns out to be a cricket.
Butterflies and spiders are vermin???
