Vespa velutina can spread both by a natural diffusion process or by a passive and accidental transport of inseminated queens due to human activities. In the latter case, the species can colonize new areas of Piedmont and Liguria, or even other parts of Italy.

The LIFE STOPVESPA project - despite its focus is in Liguria and Piedmont, i.e. two regions affected so far by the presence of the Yellow-legged hornet in Italy - includes also measures on the whole Italian country. In fact, the activation of a Vespa Emergency Team, is provided; such a team will be able to intervene, in accordance with the local authorities, in all the regions of Italy where the Yellow-legged hornet will be reported, contributing to the creation of a local monitoring network and transferring the methods and techniques to control the populations.
