How to Get Rid of Wasps: A Practical Guide
What works, what to avoid, and why a European wasp nest is a job for a professional.
Written by Muzi Tsolakis, Founder and Competency Assessor, Pest Management Victoria. Last reviewed 7 July 2026.
Wasps are among the more urgent calls we take at Protech, and for good reason. A mature European wasp nest in a wall cavity or an underground burrow can, according to the Better Health Channel, exceed 100,000 wasps by late summer, and disturbing one without the right protection is genuinely dangerous. This guide covers what you can do safely around the home, the folk methods worth skipping, and the point at which a nest becomes a job for a professional.
First, know which wasp you have
The introduced European wasp is the one we remove most often across Melbourne. Workers are about 15 millimetres long, bright yellow with black triangular markings and yellow legs, and they nest out of sight in the ground or in cavities. Native paper wasps look quite different: slender, with a narrow waist and dangling legs, building a small open honeycomb of cells under eaves and rails. Paper wasps are far less aggressive and their nests are visible, which makes them easier to judge. The European wasp is the species that turns a wasp problem into a serious one.
Prevention that reduces wasps around your home
Wasps forage for protein and sugar, so an outdoor space that offers neither holds far less appeal. Keep food and sweet drinks covered when you eat outside, secure your bins with tight lids, clean up fallen fruit under trees, and rinse recycling before it goes out. Agriculture Victoria's European wasp page notes that around 80 per cent of nests are in or near the ground, so through spring it is worth checking retaining walls, rockeries, compost heaps and subfloor vents for early activity, and sealing gaps around the roofline before a queen moves in.
A small early-spring nest is roughly golf-ball sized and easy to deal with; the same nest left until February can be the size of a basketball. Catching one early is by far the easiest path.
What is safe to do yourself, and what to avoid
For a small, clearly visible paper wasp nest, careful treatment after dark with protective clothing is within reach of a confident homeowner, since the colony is small and less defensive. Beyond that, caution is the right instinct. Do not block a nest entrance, because trapped wasps will chew a new way out, sometimes into the room next door. Do not try to burn or flood a nest, and never disturb a European wasp ground nest, which can send out defenders in seconds.
It is also worth setting aside the folk methods that circulate online. Fake or decoy nests and essential-oil sprays have little reliable evidence behind them, and relying on them around a European wasp nest gives a false sense of safety. Sound prevention and, where needed, professional treatment are what actually work.
The sting risk is the reason to be careful
A wasp has a smooth stinger and can sting the same person several times, and a colony that feels threatened mobilises large numbers at once. The Better Health Channel notes that around one in ten people who receive multiple stings develop an allergic sensitivity to later stings, and its page on allergies to bites and stings records that around three people die each year in Australia from a severe allergic reaction to stinging insects. Symptoms of anaphylaxis, including difficulty breathing, throat swelling and collapse, can develop within minutes and need adrenaline. If someone shows a severe reaction after a sting, call 000 immediately.
When to call a professional
Any European wasp nest, a large or hard-to-reach paper nest, or a nest anywhere near where children and pets play, is best handled by a licensed technician. We locate the nest, treat it directly with the right equipment and protection, and clear it safely. Our wasp nest removal and control covers homes and businesses across Melbourne, and we can usually attend quickly.

Dealing with wasps FAQs
How do I find a European wasp nest?
Watch the wasps on a warm day and follow their flight path back to a fixed point, because foragers travel in a fairly straight line to and from the nest. Around 80 per cent of European wasp nests are in or near the ground, under retaining walls, in rockeries, in compost heaps or in subfloor voids, with the rest in wall and roof cavities. Once you have located the entry point, keep well clear and let a professional deal with it.
Can I remove a wasp nest myself?
A small, visible paper wasp nest under an eave can sometimes be managed carefully at night with protective clothing, though even that carries a sting risk. A European wasp nest is a different matter and should never be tackled yourself, because a disturbed colony can hold tens of thousands of insects and will mobilise defenders in seconds. For anything beyond a small paper nest, a professional with the right equipment and protection is the safe choice.
What is the difference between bees and wasps?
A honeybee is rounder, fuzzier and more golden-brown, and it carries pollen in visible baskets on its legs. A European wasp is sleeker and more intensely yellow with black markings, and it holds its legs close to the body in flight. The important practical difference is the sting: a bee stings once and dies, while a wasp has a smooth stinger and can sting the same person repeatedly. If you are dealing with a swarm of bees rather than wasps, see our guidance on bee swarms and our bee hive removal service.
Do wasps come back to the same nest?
European wasp colonies follow an annual cycle, and in most cases an old nest is not reused the following year. Our milder Victorian winters do allow some queens to survive and, occasionally, an established nest to carry into a second season as a much larger perennial nest. Removing the active nest and sealing the cavity it used reduces the chance of a repeat in the same spot.
