1. A parasiticidal aqueous suspension comprising water and from 5 to 60% by weight of a mixture comprising from 60 to 99% of an alkali metal bicarbonate and from 1 to 40% of silica particles, the silica particles having a mean diameter of less than 10 μm and, when the alkali metal bicarbonate is sodium bicarbonate, the suspension comprising less than 20% by weight of alkali metal bicarbonate, wherein said parasiticidal aqueous suspension is free of neurotoxic parasiticides.
