Tenant called about leak problem, I went with plumber. In passing, I noticed food crumbs, peanut butter jar left open, film of food on counter, chicken left directly on counter to defrost, floor sticky (evident kitchen not regularly cleaned.) Tenant called and asked me to schedule for pest control spraying because she was not "happy living with roaches." I stated this was first I heard of roaches in unit from her or previous tenants. If tenant is untidy and frankly, dirty and roaches appear, who is responsible for paying for bug spraying? I read over the rental agreement and did not see this addressed. Can I send a letter asking that regular spraying become her responsibility, should the need arise?
