I have lived here for two years. The last six months u have been getting bit by need bugs I have photographic evince of both the bites and the bugs them selves. I reputed them to the property manager and they did nothing about it because they property was in the middle of a buy out. River stone took over the property and brought in a new property manager. She did contact pest control who said the bugs were coming from the apt.below us. They also do not treat furniture so we had to throw away close to $ 2500 worth of furniture and were unable to stay in the apartment during fumigation due to having a one year old baby. I have had to spend hundreds of dollars to launder all our clothes. The manager has refused to do anything to the people under us even though they have infested two different apartments they lived in and now ours. These people have not compiled with the exterminators directions and even after 3 times of being sprayed in our apartment the bugs are still coming up from the bottom. This had been the worst thing to deal with
The complaint has been investigated and resolved to the customer’s satisfaction.
Definitely call the Health Department, if anything they might be able to make the landlord pay for the cleaning that will need to be done to get rid of them and give the tenants below you a warning about getting theirs done to prevent any further issues.
Those are bed bugs. Look into a renters advocacy group in your area. Look into the laws regarding a landlord's obligations in such an instance. It is possible your landlord is not able to force the family below you out of the building because the law prevents them from doing it.
In the meantime, get a portable steam cleaner and clean everything on a regular basis. Get a plastic protector for your mattress and some for your pillows. Reduce the clutter in your home to prevent the locations they can get into and hide. Line your clothing drawers with plastic and do not put clothing or anything else on the bed that can result in transferring the bugs to or from your mattress. There are also tenant friendly powders you can put along your baseboards to kill them when they try crossing it.
You may just be better off moving. But if you do, take massive precautions not to transfer the bed bugs to your new place. Good luck!
