Fewer treatment options are typically available for ants versus bees due to the greatly reduced difference in size between ants and their mites (the typical worker bee weighs about 100 mg, whereas even larger ants weigh a fraction of this amount). Lithium salts have a relatively low median lethal dose (LD
50), which is to say that it doesn't take much to become toxic, a fact which is especially relevant for small insects.
Upon reading, however, it appears that this may be a longshot treatment for ant colonies affected with parasitic mites which feed on the host. It probably would not be effective against most mite infestations that antkeepers observe, which are not parasitic mites, but are instead phoretic detritivores, only latching onto the host for transport, and not for feeding.
Nevertheless, I'll be looking into this further.
