Baits take the sting out of wasps at Lake Canobolas


A wet winter last year has contributed to a reduction in the number of European wasps about the city however Orange City Council staff are urging the community to report nests in recreational areas to further reduce the population.

In previous years places like Lake Canobolas have been swarmed with the insects and while the numbers are reduced, staff are taking measures to ensure the area can be enjoyed by all.

Orange City Council’s Environmental Sustainability Committee Chair Cr Neil Jones said council’s parks and gardens staff are using environmentally friendly baits to trap and dispose of the stinging insects but he is calling on residents to report all nest sightings in public spaces.

“The baits are effective and give staff a good indication on the population numbers but serious reductions only happen when they can find a nest and dispose of it,” Cr Jones said.

“The nests are greyish in colour but are usually in the ground and the wasps enter through a small hole.”

European wasps are similar in size and shape to a bee but their abdomens are slightly more cylindrical and they have distinctive yellow and black triangular markings. Unlike bees, wasps can sting multiple times.

“European wasps tend to build nests in the ground or in sheltered areas and have a tendency to be aggressive if they’re disturbed so it’s important people don’t touch them but instead call the council,” Cr Jones said.

“But there is plenty you can do at home to reduce the number of wasps about the place. Place all cat and dog food, particularly meat, inside if you can or in the garage. Wasps can travel up to a kilometre in search of food and they can detect meat on the air quickly.

“Also make sure any fruit that falls from garden fruit trees is not left to rot on the grass because fruit is a great source of protein for wasps.

“It’s also a good idea to clean up after an outdoor barbecue quickly so the smell of meat can’t travel as far and attract the insects to your home.

“If you find a nest at your home, it’s best to call a private pest control business to come and dispose of it.”

If you find a wasp nest on council-owned land please call the council on 63938000.

Top tips to discourage European wasps:

  • Do not leave fallen fruit or food scraps lying around the yard
  • Avoid leaving uneaten pet food or dog bones outside
  • Make sure rubbish bins have tight fitting lids
  • Keep compost covered at all times
  • Keep swimming pools covered when not in use
  • Cover exposed food at picnics and barbecues
  • Don't drink out of cans or bottles, use clear containers or a straw.
