The first Asian giant hornet nest of the year has been found in Washington state, and plans are being developed to eradicate it, likely next week, the state's agriculture department said on Thursday.
The so-called stinging "murder hornets," the world's largest hornets, can grow to two inches in length and prey on native bee and wasp populations, consuming honeybee hives and threatening agriculture.
A day before the nest was located, Washington and Oregon state Department of Agriculture employees gathered in an open-air classroom just south of the Canadian border to learn how to trap, track and eradicate the invasive species. Thousands of traps baited with orange juice or jam are hung in trees along likely hornet flight paths. Once spotted, the hornet must be tracked to its nest, so its queen and other hornets can be destroyed, ideally before reproducing.
Once a nest of Asian giant hornets is confirmed by thermal imaging to be in a tree, the tree is wrapped in plastic wrap to prevent escape while its trunk is hit with a piece of wood to get the hornets out so they can be vacuumed up and eradicated.
