Indonesian Red Cross (PMI) volunteers removed two hornet nests in West Sumatra after the swarm attacked residents.
Footage filmed on 26 August in Bukittinggi shows a large nest belonging to lesser banded hornets, built up in a tree at a height of about 15 meters.
Residents around the tree were restless because a hornet stung a resident after breakfast at a nearby food court.
Meanwhile, in another place, in the past three days four residents were stung by a swarm of hornets that nestled between the roofs of houses belonging to local residents.
Lesser banded hornets are known to have potentially lethal stings in enough numbers, and can cause anaphylaxis in people who are allergic.
Residents reported to volunteers to evacuate the hornet nest for fear of attacking children who often play in the fields around the site.
PMI Bukittinggi volunteers who removed the nest sprayed insect venom to paralyse the swarms of hornets that have begun to emerge from their hives.
The size of the hornet nest was more than one metre, causing officers to break into the roof of the house to take out all the nests attached to the underside of the roof.
“At the first location, a hornet stung a resident who had just had breakfast at the food court around the nest.
Here the hornets stung four people, so the people asked PMI to help evacuate," said Head of PMI Bukittinggi City Headquarters, Ahmad Jais.
