if the children were being mistreated to the extent of maybe abuse , then ACS must be called ASAP.
the situation that coffee addict describes seems like a family that could just simply use some money for like a “cleaner” home and money to get help watching the children-babysitter.
a cluttered and bedbug filled home isn’t safe nor healthy, therefore something must be done. but, I don’t think the answer is calling ACS. I think that the answer might be a new home(because bedbugs never go away, they just come back), and someone to help run the home and watch the kids.
