An aqueous parasiticidal suspension for treating Dermanyssus gallinae comprising water, silica, and at least 20% by weight and not more than 45% by weight of sodium bicarbonate in dissolved and undissolved form, wherein said undissolved sodium bicarbonate is in the form of particles, and wherein said particles of undissolved sodium bicarbonate have a particle size distribution such that at least 50% of the particles have a diameter of less than 150 μm.
A method for controlling the development of Dermanyssus gallinae on animals raised in buildings, comprising:
- contacting the environment of an animal in a building in need thereof with an aqueous parasiticidal suspension comprising silica, water and at least 20% by weight of dissolved and undissolved sodium bicarbonate, wherein said suspension comprises said undissolved sodium bicarbonate in the form of particles dispersed in an aqueous phase, said particles having a particle size distribution such that at least 50% of the particles have a diameter of less than 150 μm, and
- drying said suspension such that dissolved sodium bicarbonate forms a cement between the undissolved sodium bicarbonate particles.
