Abstract: A method for controlling the development of a parasite in an animal's environment, comprising: contacting the environment with a powder free of a substance that is neurotoxic to the parasite, the powder comprising at least 60% by weight of alkali metal bicarbonate particles and at least 1% by weight of silica, wherein the bicarbonate particles have a particle size distribution such that at least 75% of the particles have a diameter of less than 100 ?m, wherein the parasite is an acarid, and wherein the bicarbonate particles and the silica combined in the powder together comprise a parasiticidally effective synergistic combination.

Abstract: Parasiticidal aqueous suspension typically comprising from 1 to 15% by weight of silica and from 30 to 45% of alkali metal bicarbonate, and method for controlling the development of parasites on animals reared in buildings, according to which the animal's environment in the building is brought into contact with this aqueous suspension.

Abstract: Aqueous parasiticidal suspension typically comprising from 1 to 15% by weight of silica and from 30 to 45% by weight of sodium bicarbonate and method for controlling the development of parasites on animals raised in buildings, according to which the environment of the animal in the building is brought into contact with this aqueous suspension.

Abstract: A pediculicidal process to combat the growth of the louse Pediculus humanus, in which the louse is brought into contact with a composition comprising at least 60% by weight of alkali metal bicarbonate. A parasiticidal process, in which a parasite is brought into contact with a composition in gel form comprising from 40 to 50% by weight of alkali metal bicarbonate particles, from 15 to 25% by weight of silica, and from 35 to 45% of water. In particular, a process for eliminating the louse Pediculus humanus from human hair, in which the head hair is brought into contact for at least 1 hour with the composition in gel form, the operation of bringing into contact for at least 1 hour subsequently being repeated at the earliest two days later.

Abstract: Use of a powder comprising more than 40% by weight of sodium bicarbonate, for its acaricidal effects in the storage of cereals.
