I totally agree with WebyJ. Sometimes people have a hard time calling the police in a case such as yours, however, it is the wisest thing to do. You are not being the bad guy; you are reporting a serious problem that will affect the health of others. It's also safer for you if you keep out of the situation. If I were in your shoes, I would call the police when I was away from the home - do it at a time when you would normally be away or perhaps in the evening when you and DH go out for dinner or whatever. That way your husband will be home if there is any unpleasantness from the neighbors. Again, you are not being the bad guy by calling the police.
