Doktor Doom questions.

I used the 3 ounce Doktor Doom fogger last night. I set it off at 10:30pm after the lights turned off and had time to cool, sealed the room, and came back at 2:30am to air the room out. This morning, I went to check the plants hoping to see results. Nothing except a few dead on the leaves, that's it.

I'm wondering it the bomb kills on contact or if it takes up to 24 hours to work completely?

Anyway, I put up two of the no pest strips vapor strips and turned off the fans for a couple hours. Anyone know how long till those will start to kill?

Thanks.
