My husband works as an electronic technician for the local government. He is responsible for maintaining the large pump stations for the sewer division. One summer they had a major problem that had nothing to do with the pumps. The had an infestation of a rare kind of hornet. When they called out the exterminator the worker informed them that the variety that was in the building was a European Hornet that were known to be very vicious and they were three times the size of a normal hornet. He said that they rarely came across a true infestation of them but when they did they did everything to eradicate them. These are not like you typical honeybees that really do no harm to people. These hornets have been known to attack people and animals when their space is invaded and their sting can cause extreme pain. The hornets had set up house in the walls of the pump station and they actually ended up putting a tent over the facility to kill off the nest. It was either that or tear open the wall where they felt the main nest was. This would not only require added repairs but it could have been dangerous if they angered the entire nest. The first time I saw one of these in person I was terrified. I don’t like bees to begin with but this one looked like something out of a nightmare. I am not sure how my husband and the other workers would have handled those creatures everyday but I am glad it wasn’t me.
