Wasps are flying insects that will attack and sting humans if approached or disturbed. They are typically black or tan in colour and look similar to ants as they have three distinct body parts (head, thorax and abdomen) and a clearly defined waist. Wasps usually live in colonies and often build their nests in sunny locations such as trees, plants, subfloor areas, under eaves or pergolas or on the outside walls of houses.
Types of Wasps
Across Australia, there are over 12,000 species of wasps, however only a few species are considered pests in urban areas. Throughout Joondalup and the northern suburbs of Perth, most wasp problems are caused by:
Paper Wasps
Black or tan coloured wasps, with yellow/orange bands on the abdomen. 10 – 15mm long. Build grey, papery-looking, cone-shaped nests containing hexagonal cells under eaves, pergolas or in shrubs or other vegetation. Will attack and sting if disturbed or threatened. In the event of a Paper wasp sting, apply an icepack to the bitten area and seek medical attention if symptoms persist.
European Wasps
Brightly coloured wasps with yellow and black stripes, and yellow legs. Squat in appearance and fly with their legs close to their body. 12 – 16mm long. Build basketball-shaped nests in cavity walls, ceilings, logs, trees, and even underground. Will attack and sting if nests are disturbed or threatened. Very aggressive. In the event of a European wasp sting, apply an icepack to the bitten area and seek medical attention if symptoms persist.
Problems caused by Wasps
The greatest problem caused by wasps is their ability to attack and sting humans, particularly when disturbed or threatened. Wasps can sting more than once, so caution needs to be taken if wasps are found around commercial or residential premises. Most wasp stings result in little more than a burning pain and localised swelling and can be treated with an icepack, however if there is evidence of a more severe reaction medical attention should be sought immediately.
