[1] The biology of O. mercator is nearly identical with Oryzaephilus surinamensis (the sawtooth grain beetle).

Further, the metabolism of a population of insects results in an increase of water absorption into the grain, which can cause mold growth.

[2] The fumigants used for control of insects in grain do not leave a residue when used properly[3] but are highly toxic and require a qualified pesticide applicator.

[2] In the home, products susceptible to infection should be kept in sealed containers to exclude these beetles.

[1] Freezing infested foodstuffs at -18 °C for six days will kill all stages of the O. mercator life cycle.
