Volunteers supplied with traps to try to limit numbers as Queens begin to create nests.
Four Asian hornets have been found in the Bailiwick in the first three months of the year.
The two most recent were in Herm and at a tucked away nature reserve in the Vale parish.
The Asian Hornet Team has sent out around 260 traps to volunteers to create a network across Guernsey approximately every 500m.
It is this time of year that queens emerge from hibernation, source nectar and when strong enough, begin a nest.
Julia Henney is the States' natural environment officer and says volunteers play a crucial role:
"This is our first line of defence to prevent Asian hornets establishing and it is only possible with their support.
"This year is set to be a particularly critical year for this programme, with queen hornets having been caught earlier than any other year.”
Asian Hornets were first discovered in Guernsey in 2017 and it is believed a series of strong easterly winds had brought them in from France.
Since then, 157 queens have been captured and 62 nests destroyed.
