European Wasps / Vespula germanica
In Australia, the European wasp (Vespula germanica) is a well-established pest. This non-native wasp was discovered in Australia for the first time in Tasmania in 1959. They were also well-known in Victoria, South Australia, New South Wales, and Western Australia by 1978.
Identification:
European wasps are large with bright yellow and black banded abdomens and two black spots on each yellow band.
They have two pairs of clear wings, the first of which is larger.
They fly with their legs close to the body and have black antennae.
Danger to humans:
When their nests are disturbed, European wasps become more aggressive than bees.
Wasps, unlike bees, can sting multiple times and do not die after stinging.
The sting causes a burning sensation as well as swelling. A more severe systemic reaction may occur if there are multiple stings.
Wasp, bee, and ant stings can cause an allergic reaction (anaphylaxis) in some people, but this is uncommon.
There is an effective treatment available, which entails known bee/ant/wasp sting allergy sufferers carrying a special kit when outdoors.

Mud-dauber Wasp / Sceliphron laetum
Identification:
Mud-dauber wasps (Sceliphron laetum) or mud wasps come in a variety of colours and sizes, but the majority of them are black or black and orange. The very long skinny part of their abdomen distinguishes them from other mud nest building insects. As a result, scientists refer to them as “thread-waisted wasps.”
Danger to humans:
Mud-dauber Wasp stings can be painful, but attacks are uncommon. To alleviate the pain of the sting, apply an ice pack. If there is evidence of an allergic reaction, seek medical attention.

Asian Paper Wasps / Polistes chinensis
Identification:
Asian paper wasps are an introduced species and resemble our native paper wasps, but they can be distinguished by their distinct pattern of stripes and spots.
Typically 1.5-2.5 cm in length, yellow and black with orange antennae. They resemble European wasps in appearance, but have a higher proportion of black, a lower proportion of yellow, and a thinner abdomen. Unlike native paper wasps, the cells in Asian paper wasp nests are exposed.
Danger to humans:
Like native paper wasps, they typically attack humans only when their nest is disturbed. Unlike stings from native paper wasps, these stings can be life threatening even to those without anaphylaxis.
Like many wasp, bee, and ant stings, their sting can cause an allergic reaction (anaphylaxis) in some people. There is an effective treatment available, which entails known bee/ant/wasp sting allergy sufferers carrying a special kit when outdoors.
Paper Wasps
Identification:
Paper wasps have a small head, medium-sized eyes, and long antennae. The body is slim, with a narrow waist. There are two pairs of brown-tinted wings, the first of which is larger. The abdomen is mostly black with some yellow/orange bands.
Danger to humans:
Native paper wasps are smaller and lack the bright yellow markings of European wasps. They are only aggressive when protecting their nests and are otherwise valuable insects to have in the garden.
Paper wasps can sting painfully, but they are not as aggressive as European Wasps. They typically attack humans only when their nest is disturbed. A more severe systemic reaction may occur if there are multiple stings.
Wasp, bee, and ant stings can cause an allergic reaction (anaphylaxis) in some people, but this is uncommon. There is an effective treatment available, which entails known bee/ant/wasp sting allergy sufferers carrying a special kit when outdoors.
