About Parasitic Wasps in Australia
Parasitic wasps make up a huge group. Most are tiny, and they lay their eggs on or inside caterpillars, beetle grubs, aphids and other invertebrates. The young wasps feed on the host as they grow. Gardeners and growers value them because they help keep many plant-eating creatures in balance.
What Parasitic Wasps in Australia Look Like
Most are only a few millimetres long and go unnoticed. A few are larger, such as the long-bodied ichneumon wasps, which may have a long, thin egg-laying tube that looks like a stinger but is not used on people.
Nests and Life Cycle
Parasitic wasps do not build nests. The female searches for a host, lays her eggs on or inside it and moves on. Cocoons, such as small white or yellow silky cases attached to a caterpillar, are often the only sign you'll see.
Is It a Problem at Your Property?
Parasitic wasps are helpful and are not a concern around homes. If you are seeing wasps entering a hole in your wall, roof or ground, that is a different wasp - contact us and we will identify it.
If wasps are nesting where they shouldn't be, we can help with wasp control services - contact us for an inspection and a clear written quote.

Parasitic Wasps in Australia FAQs
Do parasitic wasps sting people?
Most cannot sting people at all, and the long tube on some species is used to lay eggs, not to sting.
What should I do if I find a wasp nest?
Keep people and pets away, don't block the entrance and don't knock or spray the nest. Contact us and we will identify the wasp and arrange an inspection.
Can you identify the wasp for me?
Yes. Tell us what you can see - size, colour, nest shape and where it is - and we will identify it when we inspect.
