The "safe" level used to allow entry is usually under 5ppm.
This level typically occurs within 24 hrs of removing the tent and opening house up.
If you wanted to be safe, wait a few extra days with the windows wide open and plenty of air flow entering house. When the house is cleaned for the dead bugs, just make sure all the surfaces are wiped down (which is usually done by cleaners anyway).
