Call your city or town health inpespector. In most major cities it is the landlords obligation to hire a an exterminator. In the case of bed bugs I believe there is more of an urgency and most city inspectors will come out within days, now that bb’s have reached epidemic levels not only in the U.S., but in many countries around the world. In some U.S.cities there are “lanlord/tenant agreements”, which are locally legal and binding contracts that state what the obligation of a landlord and tenant is, and most contain a clause which says that repairs, maintenance, etc.,which are landlords obligations, and what recourse a tenant has when the landlord refuses to repair or maintain his rental properties. In some cases, the tenant may pay for the repairs and deduct from the rent after following various steps first, such as, notifying the landlord via certified letter, prior to the tenant paying for said repairs. Please READ your lease and call your city or town’s health department or building inspectors first,as these ordinances may vary. You can always file a case in local claims court without an attorney,after paying for the repairs,if all else fails, and moving is not an option. I am not a lawyer, and this is not legal advice. I hope this helps. Bed bugs are a public health hazard. And not taken lightly by many local elected, or appointed officials. I hope this helps.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
