You should talk to people locally. First, speak to the management company and the pest control company (if there is one, I’m concerned that it appears as though the management is doing this with building staff). Then try the health department and the pesticide applicator regulator in your state (in NY it is the Department of Environmental Conservation). Your building management may not be able to do pesticide applications in your apartment. You can ask to see the license of the technician that comes to you home, as well as the names and labels of all pesticide products being applied. Weekly sprayings of your mattress and other things you state suggest there is something not quite right with this treatment plan. If the management is doing it without hiring a licensed pest control company, then that may explain many things.

In most cases, people have the opposite problem, a management company that is not willing to consider other apartments where the infestation may spread. But in your case, you should have a talk with them and figure out what the plan is, whether there were bed bugs found in your apartment or others nearby, what they are using and how, etc.

I am a student and also working full time. I only have one day off a week and each Friday is seriously disrupted by having to turn my apartment upside down and do all of this laundry. How long are they allowed to continue with this? They’ve given no date that they anticipate this practice ending. It seems excessive. I live in the garden unit and there has been no occurrence of bed bugs on this floor. I feel that my privacy is being invaded.
The maintenance people are sloppy, leaving enough chemical solution behind to damage the hardwood floors and even soaked the inside of my shoe once because they are so careless. They spray some chemical stuff on my mattress every week. How do I know that it’s not going to cause illness to me or my pets in the future? The smell lingers. This is very disturbing. Is there anything I can do? I love this apartment, but don’t know how much longer I can put up with this.
