There is a lot of talk lately about insurance companies having policies that cover Bed Bug infestations. Not only would these policies cover the cost of treatment and loss of revenue, but also the claims of "bodily injury, property damage and mental anguish" of the 'victims'. Infestations of any kind have typically been excluded in commercial insurance policies as they were considered a maintenance expense. So far the policies are for commerical properties; hotels and residential property managers.
