Citizen observations of tiger mosquitos in new areas has occurred a number of times. In such cases, we believe that it is necessary that a team of expert entomologists inspect the area and confirm the detection. Citizen sightings are a big help because detecting these insects at the country scale is like finding a needle in a haystack.

If these sightings are confirmed in the field using scientific and technical standardized protocols and methods, the public administrations and authorities responsible for follow-up actions will be informed. Also, in some cases a scientific publication helps spread knowledge of the new discovery, as done in the cases of the new detections in Andalusia and Aragon (publication pending).
