How many plants are we talking here?
10 hours in a trash bag in the dark is not going to suffocate the plants. The darkness slows their transpiration rate so you're safe.
If they are in flower, you're going to have to check for herms in the next couple weeks.
If they're in veg, meh, you should be fine.

As for finding the box.. errrrrr... that could be a problem... can you put them in like a big rubbermaid tote and lock them in your car druing the pest thing?

Oh and the chemicals... if they are in a plastic bag you should be fine. But still if they have buds on them I would try to take them to a babysitter for the day. Do you have a buddy in another complex who wants to watch your plants for you?
