Tempo Dust will usually eradicate a nest within 24 - 48 hours depending on the size and depending on whether all entry and exit points were treated. As long as they are contacting the area where the dust was applied, then it should kill them all. It might be best to also drill holes in the area you suspect the nest to be to kill the larvae which may now be old enough to emerge.
Yes, Tempo 1% Dust is a great choice to apply to the wasp nest if you have access to the opening. You should treat late in the evening or early in the morning when the insects are the least active. The wasps that come in contact with it will transfer from bee to bee, killing adults and larvae.
To get into those higher areas, you could use the Dustick Duster applicator. Tempo 1% dust is the most effective dust to treat for hornets and yellow jackets. Be sure to treat in the times of the day when they are less active (earlier morning or later evening). You may also want to use a ready-to-use knockdown insecticide such as PT Wasp Freeze II. This spray will spray up to 15 away for safe and quick knockdown of flying, stinging insects.

It is not necessary to mix different types of dusts together, but it can be done. For bed bugs, we would recommend using Cimexa Dust because it can last in the wall voids for up to 10 years if it is undisturbed.
With Alpine Dust, it does either have to be injested or when the dusts gets on them, it will dry them out. Depending on the stage of life the bed bug is in, it could take up to two weeks for the bed bug to be dried out.
