Sharp rise in Asian hornet nests in Brussels
Brussels has seen a worrying increase in the number of Asian hornet nests this year, with five times more having been reported compared to last year, Bruzz reported on Tuesday.
This invasive species, which is originally from Southeast Asia, is now increasingly being spotted across the Belgian capital. A total of 112 nests have been reported via Waarnemingen.be, which is a fivefold increase compared to last year, according to Olivier Van Sintejan, a pest control expert from Bye Bye Wesp.
Speaking to Bruzz, Van Sintejan said that "Brussels is facing a serious problem". Since April, local beekeeper and hornet exterminator Arthur Van Peene has destroyed 40 nests in the region. "It's a massive issue that gets worse every year," he said.
Threat to biodiversity
Data from Brussels Environment confirms the 112 nests recorded so far this season. Spokesperson Lynn Tobback said that this figure is likely to rise, as hornets typically remain active until the first frost.
“In group attacks, they can be fatal”
The Asian hornet poses a significant threat to biodiversity. “One nest consumes around 11 to 12 kilos of insects annually,” said Van Sintejan, adding that this can disrupt pollination and affect plant life. The hornets also present a public health risk due to their aggressive defence of their nests. “In group attacks, they can be fatal,” he said.
Mild spring
The mild spring has contributed to the boom by allowing more queens to survive the winter. Van Peene also said that there was a lack of public awareness in Brussels. “In Flanders, nests are recognised and reported more quickly, but in Brussels they often go unnoticed,” he said.
The Brussels authorities urged residents to report nests via Waarnemingen.be or to contact Renature.brussels. In emergencies, the public should call 112 and avoid approaching the nest.
