A device positioned beneath a beehive for use in controlling parasites in
beehives including a base structure and a number of bars extending across
the base structure. The bars are held spaced from one another by
crosspieces engaged with the bars and the base structure. The bars are
spaced from one another to enable waste and parasites to fall between the
bars. The bars are formed of a low-adhesion material to prevent the
parasites from being able to climb onto the bars and back into the
beehive.
