The invention relates to a sticking cotton treatment method which is intended to reduce the stickiness of cotton fibres thus treated. The inventive method comprises the following steps consisting in: a) seeding the cotton fibres with the aid of bacteria by means of spraying, preferably uniformly, from an aqueous suspension of said bacteria, such as to obtain a maximum resultant moisture content of 16 %; b) storing the cotton fibres thus treated in the form of a compressed bale; and c) leaving the seeded bacteria at a temperature such as ambient temperature for at least one week approximately.
