Bed bugs are a pervasive problem that is difficult to resolve on a permanent basis. Beg bugs are also not a serious health risk for most people. They are highly annoying but don't put most people at any kind of a serious health risk.
CPS is unlikely to be of much help on the issue unless one or more of the children actually have serious reactions to the bed bugs. You might get better results by offering dad assistance in getting rid of the bed bugs.
