Express your concern about roaches in a polite and forceful manner to the landlord. Request that the landlord pay for an exterminator. Keep a written record of every conversation. Date every recording.
Take pictures of the roach problem for visual documentation purposes. Keep all receipts of any extermination products and/or fees paid out by you, the tenant, if the landlord refuses to take care of the problem or does an insufficient job. Explain and agree with your landlord that you will deduct any necessary monies from your rent for extermination products or services paid for by you, the tenant, out of pocket. Document and date this verbal agreement.
Deduct these monies from your rent with a written explanation and photocopies of receipts for your landlord's records. Attempt, once again, to settle these matters with your landlord without involving the courts. Document and date this attempt.
Contact an attorney and proceed with a lawsuit if the landlord threatens you with eviction and/or enters your home and begins removing your property -- himself or through a third party -- without express written advance warning. Present your written documentation and receipts to a lawyer as evidence for your case. In Maryland, for example, a landlord must provide at least a written notice of eviction at least 30 days in advance of the eviction date. You can sue a landlord under these conditions backed by the enforcement of the Tenant's Advocate Rights guidelines and the attorney general's office in most states.
