One of the biggest issues tenant reports to landlords is pest infestations. All pest control issues should be handled immediately to prevent a bigger issue. Pest control can be expensive to take care of after the infestation has become large. The responsibility of who should the handle issues may cause conflict between landlord and tenant. The lease may cover who is responsible for pest control, and the landlord must ensure that there are no infestations in the unit prior to the tenants moving in.
