I posted a question late last week about how to get rid of the pesticide odor that is lingering in my apartment, and was told to ventilate. I have done that for the past 5 days and the smell in still there. I was wondering if anyone else had any hints on how to get rid of it?

If the smell is lingering this long, something is wrong. Is there an apartment underneath you that was sprayed at the same time? Did any of the spray get into any fabrics/carpets? I would suggest calling the exterminator directly and have the manager come check out this odor. You may need to have a remediation done, like they do with hazmat contamination.

Try an air purifier
