The kids in that home were in danger of getting very sick. Roaches and e.coli from feces everywhere? Good God...DCF may have actually saved those kids lives by pulling them out!
When our mothers told us to wash our hands after using the toilet, it was because people can die from the bacteria that might be on our hands. E. coli is found in feces - human and animal - and those roaches were crawling through it, spreading it around the house. And it only takes a trace in the upper digestive system to cause havoc.
Also, I want to say that, for the record, my house is neat as a pin. No clutter, no mess. Smells like vanilla candles or ylang ylang (or Pine Sol or bleach) most of the time. There's nothing I enjoy more than pushing the Swiffer around the house or cleaning the window sills. It's a way of unwinding after putting in full-time+ hours at the law office. Takes about 40 minutes total per day to maintain.
Edited to add: I don't clean the window sills everyday. Swiffer, yes.
