Dry ice can also be used to perform the same task:

1) seal the entrance/tape up holes,
2) add an empty hive body on top of the hive.
3) Place a block of dry ice on top of an inner cover (with hole[s]), and
4) place the outer cover on top.
5) wait

The CO2 is heavier than air, so will drift down through the hive,
suffocating the bees.

Haven't tried it myself, but have heard that it works.
