The present invention relates to a distribution system (1) for distributing an olfactory attractant (3) that stimulates ovipositioning of insects, comprising a central receptacle (2) such as a container for holding an olfactory attractant (3) and/or for holding a source of olfactory attractant (3), a delivery system (4) comprising tubes (5), pipes and/or ducts, said tubes (5), pipes and/or ducts coupled to the receptacle (2) and ending at locations (6) where ovipositioning is desired, for delivering a liquid or gas from the receptacle (2) such as a container (2) to said locations (6), and a driver system (9) for moving the attractant (3) through the delivery system (4) from the receptacle (2) such as a container (2) to said locations (6). The invention also relates to a method for stimulating ovipositioning of insects, such as black soldier flies, comprising delivering olfactory attractant from a receptacle such as a container to multiple ovipositioning areas via a driver system, said ovipositioning areas preferably located in a cage for insects.
