Welcome to the board mkat2003. I'm sorry I don't have any expertise in pesticides, this place might be able to help you out National Pesticide Information Center they have a contact number there too and links to other sites that might be able to help. Also would suggest you contact the company who did the tenting and ask their opinion.
Sorry not to have a set answer for you but feel this is one for the professionals :-) Good luck and please let us know what answers you get as I'm sure you are not the only one that this has happened to.
