This paper estimates the ecosystem services return on investment in government control of the introduced European wasp (Vespula germanica) in the state of Western Australia. The predictive model used accounts for uncertainties in the spread and impact of V. germanica on provisioning ecosystem services, represented by pollination, apiculture and viticulture, and cultural ecosystem services represented by households. Results produced by simulating a 20-year period suggest government expenditure on management will generate net benefits of AU$3.2–6.3 million per year, most of which will accrue to producers of pollination-dependent crops. This provides justification for investment from the government’s agriculture portfolio to manage an insect often thought of as an urban pest.
