A process is described for the control of the development of mosquitos in a body of water, by spreading on the body of water a particulate carbohydrate compound. The carbohydrate compound may be a given compound that forms a hydrophillic gum-like layer once spread on the surface of the water. The gum-like layer prevents the development of mosquito in the larvae and pupae stages. It is also believed to inhibit the laying of eggs on the water surface by the female mosquito. The layer found is environmentally safe as the carbohydrates used are common in food products.

A method for killing immature mosquitoes in a body of water comprising spreading on the surface of the body of water a particulate, solid carbohydrate compound that is non-soluble in water and capable of hydrating, the compound being spread in a quantity sufficient to hydrate at the surface of the body of water and form a substantially unbroken, floating hydrated carbohydrate layer of sufficient thickness to retain the mosquitoes below the surface of the body of water and out of contact with air above the surface of the body of water thereby suffocating the mosquitoes in the body of water.
