Protecting your health and your claim
Throw out contaminated food for safety, photograph the damage before you discard items, and keep receipts for anything you have to replace. This documentation protects both your health and any future claim.
Food that roaches have gotten into should be discarded — it is not worth the risk. Before you throw away damaged belongings like clothing or small appliances, take clear, dated photos so there is a record of the condition. Save receipts for replacements and note the dates you bought them.
Report the damage to your landlord in writing along with the ongoing infestation, so it is documented as part of the larger problem. Keeping this paper trail matters, because it shows the real cost of a situation the landlord may have been responsible for preventing. If your losses are adding up because of an infestation your landlord ignored, a free review can help you understand your options.
