Wasps & Bees
Wasps & Bees near you
Before anyone treats anything, somebody has to say what the insect is, because the four common possibilities lead to four different outcomes. European wasps are an introduced pest and are destroyed. Native paper wasps build a small open comb under an eave and are often best left alone. European honey bees are livestock, and a swarm of them is usually collected rather than killed. Native bees are generally harmless and need nothing done at all.

The distinction that catches people out is the honey bee one. Keeping honey bees in New South Wales requires registration as a beekeeper under the Biosecurity Act 2015 — the requirement applies from a single hive, and registration is valid for two years. So the cheerful idea of keeping the swarm that landed on your lemon tree comes with a legal obligation attached, and every other state runs its own registration scheme for the same biosecurity reasons.
The other thing worth knowing early is that a swarm and an established colony are different jobs. A swarm hanging in the open is temporary, docile and straightforward for a beekeeper to collect. A colony that has been inside a wall cavity or a chimney for months has comb, brood and stores in it, and removing it is building work as much as bee work.
Telling a European wasp from a paper wasp, a honey bee or a native bee
- European wasps are bright yellow and black, hairless, fly straight and fast, and are strongly attracted to meat and to sweet drinks left outside.
- Paper wasps hang a small open comb of cells under an eave or a pergola beam and dangle their long legs in flight.
- European honey bees are furry and golden-brown, visit flowers rather than picnic tables, and swarm as a dense cluster on a branch or fence.
- Native stingless bees are tiny and black and live in a small entrance tube; they are harmless and should simply be left in place.
- Mud daubers and potter wasps build small mud cells on walls and are solitary rather than colonial.
- Any nest in the ground that produces fast, aggressive insects when the mower goes past deserves distance and a phone call, not investigation.
A swarm on a branch and a colony in a wall are different jobs
A swarm is a colony in transit. It has left its old home, it is clustered around a queen while scouts look for a new one, and it has no comb, no brood and nothing to defend, which is why swarms are usually calm. A beekeeper can often collect the whole cluster into a box in a short visit, and it is worth making a couple of phone calls to find one before anyone reaches for insecticide.
An established colony inside a wall, a roof void or a chimney is the opposite. It has built comb, it is storing honey, it is raising brood and it will defend all of it. Removing it properly means opening the cavity, taking out the comb and the stores, and then sealing the void. Killing a colony and leaving the comb in place is the mistake that produces the next problem: honey leaks through plasterboard, it attracts ants, cockroaches and small hive beetles, and the residual scent draws another swarm to the same cavity next season.
That is why a quote that involves opening up a wall is not an upsell. The cavity has to be cleared and closed, or you will be doing this again.
Keeping the swarm makes you a registered beekeeper
In New South Wales, anyone who wants to keep one or more hives of honey bees must be registered as a beekeeper, a requirement made under the Biosecurity Act 2015, and the registration is valid for two years. The point of the scheme is disease surveillance: registration is how a state can trace and contact hive owners when an exotic bee pest turns up, and unregistered hives sit outside that system entirely.
Every state and territory runs an equivalent registration scheme with its own authority, its own fees and its own conditions, and there are usually local rules as well about where hives may be placed on a suburban block. If a swarm has landed on your property and you like the idea of keeping it, the order of operations is to register first and then find a mentor, not the other way around.
If you do not want to keep it, that is completely reasonable, and a local beekeeper almost certainly does. A collected swarm goes into a managed, registered hive, which is a far better outcome than an insecticide treatment for everyone involved.
The Australian wasp and bee year
- Spring is when honey bee colonies build up and swarm, so this is when a cluster appears on a fence or a branch.
- Spring is also when a wasp nest is smallest and easiest to deal with, which makes an early call cheaper than a late one.
- Summer builds wasp numbers steadily, and European wasp nests in southern Australia can become very large by late season.
- Late summer and autumn are the peak nuisance period, when wasps go looking for protein and sugar around outdoor eating.
- Autumn is also when an unnoticed nest under a floor or in a retaining wall finally makes itself known.
- Winter quietens things down in the cooler states, which is the right time to seal the gaps that will be used next year.
What a competent nest treatment involves
- Identification first, from a safe distance and preferably from a photograph, because the species decides the whole approach.
- Locating the actual nest rather than the entry point, which for a wall or ground nest may take some observation.
- Treatment at dusk or after dark when the colony is home, rather than during the day when foragers are out.
- Full protective equipment and an agreed exclusion zone for the household, pets and neighbours during the work.
- Treatment of the nest itself so returning workers pick it up, rather than a spray of the entrance alone.
- For bees, removal of comb and stores and sealing of the cavity, so the void is not reoccupied next season.
- A return visit or an agreed check a few days later to confirm there is no continuing activity.
When a nest genuinely cannot wait, and what not to do
- Anyone in the household with a known severe allergy to stings turns any nest near the house into an urgent job.
- A nest beside a doorway, a clothesline, a play area or a frequently used path is a different risk to one at the back fence.
- Never block the entrance to a nest in a wall; the insects will look for another way out, which is often inwards.
- Never treat a nest from a ladder, because a sting or a startle at height is how this work causes serious injury.
- Do not burn, flood or pour fuel into a nest, which is dangerous to you and to the building and is not more effective.
- Keep children and pets indoors until the treatment period the technician specifies has passed.
- If someone is stung repeatedly or shows any sign of a severe reaction, treat it as a medical emergency and call triple zero.
Wasps & Bees: frequently asked questions
There is a swarm of bees on my fence. Do I need it exterminated?
Almost certainly not. A swarm hanging in the open is a colony in transit: it has no comb or brood to defend, it is usually docile, and it will often move on by itself within a day or two. Local beekeepers collect swarms and are generally glad to be called, so make a couple of phone calls before treating it as a pest problem. Keep people and pets a sensible distance away in the meantime, and do not spray it, hose it or throw anything at it.
Can I just keep the bees that moved in?
You can, but it makes you a beekeeper with legal obligations rather than someone with an interesting garden feature. In New South Wales, keeping one or more hives of honey bees requires registration under the Biosecurity Act 2015, valid for two years, and every other state and territory has its own equivalent scheme. There are usually local rules about hive placement on a residential block as well. Register first, get a mentor, and move the colony into a proper hive rather than leaving it in a wall cavity.
How do I tell a European wasp from a bee?
Look at the body and at the behaviour. A European wasp is bright yellow and black, smooth and hairless, with a narrow waist, and it flies fast and directly. A honey bee is furry, golden-brown, and moves between flowers rather than around the barbecue. The behavioural tell is food: wasps are strongly attracted to meat, pet food and sweet drinks left outside, and bees are not. A photograph taken from a safe distance is enough for a technician or a beekeeper to identify it for you.
Should I block the hole where wasps are going into the wall?
No, and this is one of the more reliable ways to make a bad situation worse. Insects that cannot leave by their usual route will look for another, and in a wall cavity the alternative route is very often into the room. Leave the entrance exactly as it is, keep the area clear, and have the nest treated first. Sealing the opening is the last step of the job, done after the nest is dead and, in the case of bees, after the comb and stores have been removed.
Can I treat a nest myself at night?
It is a poor idea, particularly for European wasps, for a ground nest, or for anything you would need a ladder to reach. Working in the dark, in protective equipment you do not own, next to a colony that defends itself, is how this work ends in a hospital visit. A technician does it at dusk or after dark because that is when the colony is home, and they do it with the right equipment and an exclusion zone. If a nest is small, new, accessible from the ground and nobody in the household is allergic, a retail product used exactly per its label is defensible; beyond that, call someone.

How to compare exterminators before you hire
- Choose a company that inspects first and identifies the pest before recommending treatment.
- Ask whether they are licensed to apply pest control products in your area.
- For wildlife like raccoons, squirrels or birds, look for a company that uses humane removal and seals entry points.
- Ask how they'll keep children, pets and food safe during and after treatment.
- Get the treatment plan in writing, including follow-up visits and what happens if the problem comes back.
Questions to ask exterminators before you hire
- What pest do you think this is, and how did you identify it?
- Are you licensed to apply pest control products in my area?
- What products or methods will you use, and are they safe around children and pets?
- How do I need to prepare my home before treatment?
- How many visits are included, and what happens if the problem comes back?
- Will you seal entry points so the problem doesn't return?
When to call a pro for wasp or bee removal
- Droppings, gnaw marks or scratching noises in walls or the attic
