My uncle, cousin, and her 2 daughters all live together and we know they have bed bugs without the means to deal with them appropriately. As this is my mom's brother I feel badly not inviting them to the wedding, but I also don't want to expose ourselves and our guests to the beg bugs. Any advice on tips to handle this situation would be appreciated. (giving them money to get it taken care of would not be effective in this situation do to the area in which they live, as many neighbors and people who visit them also have beg bugs)
