What do European Wasps look like?

Although European wasps (Vespula germanica) are a non-native Australian species, they are now well established throughout Metropolitan Adelaide. They can be easily identified by their black and yellow bodies, yellow legs and triangular markings on the abdomen.

While the European wasp is approximately the same size as the bee (10-15 mm), it is less hairy, has yellow legs (instead of black) and folds its wings back when resting. Queen European wasps have the same markings and colourings as other European wasps, except they are larger (up to 20mm).

Locating a nest:

It is often difficult to identify where a European Wasp nest is located as they prefer to burrow underground and in the underbrush.

In order for a nest to be destroyed, you need to locate the nest by determining which direction the wasps are flying. A good way to do this is to place a piece of food in a suitable location where the wasp can collect the food.

The wasp should then fly in a straight line towards the nest. Keep relocating the food and you will be led to the nest. A wasp will travel up to 500 metres from its nest to find food, therefore you may need to work co-operatively with your neighbours.

Nests are generally located in sheltered areas, for example, underground, in retaining walls, tree hollows and wall cavities. The nests of European wasps are made from a grey paper material.

What do European Wasps eat?

European wasps are attracted to the same foods as humans, especially sweet foods and meats.

In order to discourage European wasps around your property:

• Do not leave fallen fruit or food scraps lying around
• Avoid leaving dog food or bones out
• Make sure rubbish bins have secure lids
• Keep compost always covered
• Keep your swimming pool and spa always covered
• Cover exposed food when eating outdoors
• Do not drink out of bottles or cans, instead use clear containers or straws

What if I am stung?

Firstly, do not aggravate a European wasp because it may sting. If left undisturbed a European wasp will not be aggressive towards humans or other animals.

However, if a nest is disturbed, a wasp will release a chemical which triggers all wasps to defend the nest. Unlike bees, European wasps can sting multiple times and this sting results in a fiery pain and red swelling.

If someone has been stung:

• Apply ice or a cold pack to the sting
• Take oral analgesics if there is severe pain
• Stings to the face/neck or multiple stings may lead to severe swelling and/or an allergic reaction. If this occurs and/or the person has difficulty breathing, contact an ambulance, hospital or doctor immediately.
• If in doubt, please seek medical advice
