The NSW Environment Protection Authority (EPA) is investigating potential pesticide misuse in Corowa after samples taken from local hives and deceased bees tested positive to pesticides.
On 12 March 2025, local beekeepers alerted the EPA to an unusually high number of dead bees across at least three different hive locations. The EPA promptly collected samples, which have now tested positive for fipronil—a chemical commonly used in agriculture and pest control.
EPA Executive Director of Operations, Jason Gordon, said the EPA is trying to determine the source of the chemical and is appealing for any information from the community.
"It is heartbreaking that we have multiple hives in the area impacted by pesticides, and we are exploring all avenues for potential causes of these deaths," Mr Gordon said.
"Bees have a large flight diameter from their hives which makes them difficult to track and we have been working with beekeepers to try to determine potential flight paths.
"We are now seeking assistance from the public to try and locate the source.
"The chemical detected is used in spraying crops but is also commonly used in household insecticides to contain pests like fleas and ticks.
"Bees play a crucial role in local pollination, which helps keep ecosystems healthy and food production going and we want to do everything we can to protect them."
Mr Gordon said this pesticide misuse, whether it be intentional or accidental can be a serious offence, and individuals could face fines and potentially stronger consequences.
"Accidental pesticide misuse can occur, such as keeping and using out of date chemicals, so it's important to always read labels carefully and follow directions to ensure chemicals like fipronil are used safely and correctly.
"Safely storing pesticides in a secure location, along with properly cleaning and disposing of containers, are also essential steps in responsible pesticide use."
The EPA recommends the use of the BeeConnected app to assist pesticide users in preventing impacts to foraging bees in their area. See link: beeaware.org.au/pollination/beeconnected/.
