Sounds like you have a basis for modifying visitation. She should not be in that infested environment. The visitation needs to be revisited and it might even rise to the level of an emergency. Take photos of the bites and consult with a family law lawyer ASAP.

were you and mom married to each other? the answer is important as there are different visit standards.
if you and she were married and divorced, you have to show that the visits seriously endanger the daughter to restrict them. but reducing the time is not a restriction. that test is best interest. if the house and environment is so bad, then reducing the time does not solve the issue. restricting them to not at her house does. then you are left with serious endangerment.
if you and mom were never married, then the test is best interest based on a new illinois supreme court opinion, in re j.w. but if she has visits now, does the case help you to reduce or limit them? we do not know yet.
so, take all your papers to a lawyer for a review and consultation. ask the lawyer if he or she knows about jw. if not, find another lawyer.
