Giant Wasp Nest Found: WA's Invasion Threat Grows
15 Feb
Summary
- A massive 40-litre European wasp nest was found in Albany bushland.
- This nest was 16 times larger than a typical European wasp nest.
- European wasps are not yet established in Western Australia.
Authorities in Western Australia have removed an exceptionally large 40-litre nest of European wasps in Albany. This nest was approximately 16 times the size of a typical European wasp nest, described as being about the size of a bar fridge. The discovery in bushland near a residential area underscores the persistent threat of invasive species to the state's ecosystems.
While other Australian states have established populations of European wasps, Western Australia is actively working to prevent their establishment. The DPIRD, alerted by resident reports, successfully located and destroyed the nest. Unfortunately, the tree housing the nest had to be removed to ensure the wasps' safe eradication, as they pose a stinging threat.
European wasps can disrupt local ecosystems by outcompeting native species for resources, potentially leading to declines in native populations and reduced biodiversity. This imbalance can affect food supplies for native animals and even impact human food sources through reduced pollination. The Mediterranean climate of Australia's south coast is conducive to wasp survival.
To combat invasive species, residents are encouraged to report any wasp sightings to the DPIRD, even if unsure of the species. This vigilance is crucial for tracking and removing nests. Furthermore, planting native flora in gardens can bolster local biodiversity, making it harder for invasive species to establish themselves and thrive.
