To remove a wasp nest safely, you should call a licensed professional. European wasps and paper wasps sting repeatedly and can swarm when disturbed. Some people are allergic, and a single nest can hold hundreds or thousands of wasps. Priority Pest Services offers emergency same-day service for biting and stinging insects across Sydney. We locate the nest, treat it, remove it where it is safe to do so, and apply a residual treatment to stop wasps returning. Bookings must be made before 12pm and are subject to availability.

Why are wasp nests dangerous?
Because wasps defend their nest aggressively and can sting many times. Unlike bees, a wasp does not lose its stinger after one sting. It can sting repeatedly and release a pheromone that calls the rest of the colony to attack. A disturbed wasp nest can send a swarm into the air within seconds. For someone with an allergy, even one sting can cause anaphylaxis. For anyone, multiple stings are painful, can cause swelling and nausea, and in rare cases are life-threatening. A wasp nest near a home, child care centre, cafe or outdoor area is a genuine safety hazard.
How do I know if I have a wasp nest?
You usually notice wasps before you find the nest. The signs are consistent whether the nest is in a wall, a hedge or underground.
| Sign | What it means | Where to look |
|---|---|---|
| Wasps flying in and out of a gap | Active nest entrance | Wall cavities, roof eaves, vents |
| Paper-like nest under eaves | Paper wasp nest | Under eaves, in hedges, on fences |
| Wasps around bins or outdoor food | European wasps foraging | Near outdoor dining and bins |
| Ground hole with wasps entering | Underground European wasp nest | Lawn, garden beds, retaining walls |
If you see a steady stream of wasps flying in and out of a single gap in a wall or roof, there is almost certainly a nest inside. Do not block the hole. Wasps trapped inside will find another way out, often into your living space.
"Never try to remove a wasp nest yourself. Wasps swarm when disturbed and can sting many times in seconds."
How does a professional remove a wasp nest?
Professional wasp control is fast, safe and effective because we treat the nest at the right time and with the right product. We work at dusk or dawn when most wasps are inside the nest and less active. We treat the entrance so the wasps are controlled before they can swarm, then remove the nest where it is accessible and safe.
- Locate the nest: We find the nest by following flight paths, including hidden nests in walls and roof voids.
- Treat the nest: We apply a targeted treatment to the entrance and nest to control the colony.
- Remove the nest: We remove the nest where it is safe and accessible, so wasps do not return to rebuild.
- Residual treatment: We treat the area around the nest to control any wasps that return over the following days.
European wasps versus paper wasps: what is the difference?
The two wasps Sydney homeowners see most are European wasps and paper wasps. They look similar but behave differently, which changes how we treat them.
| European wasp | Paper wasp | |
|---|---|---|
| Nest location | Wall cavities, roof voids, underground | Under eaves, in hedges, on fences |
| Nest size | Can hold thousands of wasps | Usually dozens, up to a few hundred |
| Aggression | Highly aggressive, swarms | Defensive if disturbed |
| Sting risk | Stings repeatedly | Stings, but less often |
European wasps are the bigger threat. They nest in hidden cavities, build large colonies and defend them fiercely. Paper wasps build open-comb nests under eaves and in hedges, and are less aggressive unless you touch the nest. See our wasp control service.
Key tips to prevent wasps around your home
- Keep bins closed and clean bin lids - European wasps scavenge on food waste and meat.
- Cover outdoor food and drinks in summer - wasps are attracted to sweet drinks and protein.
- Seal gaps in walls and roofs before spring - European wasps use existing cavities to nest.
- Check eaves and hedges in spring - paper wasp nests are easiest to remove when small.
- Do not block a nest entrance - trapped wasps will find another exit, often into your home.
- Call before 12pm for emergency same-day service* if a nest is near people or pets.

Frequently Asked Questions
Can you come the same day for a wasp nest?
Yes. Wasps are covered by our emergency same-day service* for biting and stinging insects. Bookings must be made before 12pm and are subject to availability. Call us first thing in the morning for the best chance of a same-day slot.
How do I know if it is a European wasp?
European wasps are yellow and black, about the size of a bee, and fold their wings back along their body when resting. They often nest in the ground or in wall cavities, and they scavenge on food and meat around bins and outdoor dining.
What should I do if I am stung?
Wash the area with soap and water and apply a cold pack. If you have trouble breathing, swelling of the face or throat, dizziness or a known allergy, call 000 immediately. Multiple stings require medical attention even without a known allergy.
Will the wasps come back after you remove the nest?
The treated colony will not return. To stop new wasps rebuilding on the same spot, we remove the old nest where it is accessible and treat the surrounding area. Sealing the entry gap prevents a new colony using the same cavity next season.
How much does wasp control cost?
Wasp nest treatment is priced based on the nest location and size, because a nest in a wall cavity takes longer to treat than one under an eave. Call 0466 344 445 for a fixed quote, or request a free quote online.
