That's how the floors work in the UK.
They stick on the petroleum jelly or a piece of fablon placed sticky
side up. If the fablon is placed directly on the hive floor, with strong
garden mesh, old QX or similar to hold it down, the bees do not stick to
it but there is the chance of a bee inadvertently picking up a mite as
it walks across.
From what I understand, mites can survive for about four days away from
a host.
The beekeeping suppliers sell sticky inserts ready marked off in one
inch squares making it easier when counting the mite drop.
