The invention relates to a substrate, specially designed for use as an animal bed, for controlling insects, preferably flies, and which is characterised in that it comprises an absorbent substrate impregnated with at least one insect growth regulator (IGR) in a determined preferred concentration, wherein the substrate is preferably impregnated with a formulation comprising, in addition to the growth regulator, a filmogenic substance, a water-insoluble particulate mineral material, an organic solvent, one or more additives, and water, in the quantities specified in the description. The invention also relates to a method for obtaining the substrate, by impregnation with the formulation, and to the use of the substrate as an animal bed for insect control. Also disclosed is the use of the residue formed by the substrate mixed, with manure, after having been used as an animal bed, as an organic amendment for agricultural soils by means of a process of stabilisation and degradation by means of biosolarisation.
