Honey bee stings send hundreds of Australians to hospital every year. Here's how to spot a swarm, what an allergic reaction looks like, and why bees should never be sprayed.
Honey bees are vital pollinators and are protected across NSW. But for the estimated 3% of Australians with a bee venom allergy, a single sting can be a medical emergency. Across Penrith, Glenmore Park, Emu Plains and the Blue Mountains, spring and early summer bring swarms looking for new homes — often inside wall cavities, chimneys and roof voids.
A normal sting causes sharp pain, a red welt and localised swelling that resolves within a day or two. A large local reaction can cause swelling that spreads 10cm or more from the sting site and may last several days — uncomfortable but not life-threatening.
Anaphylaxis is the dangerous one. Symptoms include hives or rash spreading away from the sting, swelling of the lips, tongue or throat, difficulty breathing or wheezing, tightness in the chest, dizziness, vomiting, and collapse. Anaphylaxis usually begins within 5–30 minutes of the sting. Call 000 immediately, use an EpiPen if prescribed, and lie the person flat with legs raised.
The real cost of doing nothing
Small pest problems rarely stay small in Penrith's climate. Cockroaches can contaminate food areas, rodents can damage wiring and insulation, and termites can keep eating structural timber long before the damage is visible. A proactive inspection or treatment costs a fraction of a major infestation.

Children, people with known allergies, and anyone who has reacted strongly to a previous sting are at highest risk. If you have ever had a whole-body reaction to a bee sting, ask your GP about a referral to an immunologist — venom immunotherapy is highly effective.
If a swarm or established hive is on your property, do not spray it. Insecticide sprays on bees are illegal in many circumstances, kill a protected pollinator unnecessarily, and rarely reach the queen — the colony simply regroups and becomes more defensive. Honey left behind in a wall cavity also attracts cockroaches, ants and rodents for years afterwards.
The correct response is live relocation by a registered beekeeper wherever the hive is accessible. We work with local Penrith and Hawkesbury apiarists who can collect a swarm — usually for free or a small call-out fee — and rehome the bees safely.
Where bees are inside a wall cavity, chimney or roof void and live removal is not possible, we follow a documented, last-resort treatment protocol in full PPE, then physically remove the comb and seal the entry point to prevent re-occupation. Leaving comb in place is what causes most repeat infestations.
If you’ve found a swarm, see bees coming and going from a hole in your eaves, or have had an allergic reaction to a sting on the property, call 0400 733 222. We service Penrith, St Marys, Cranebrook, Glenmore Park, Springwood, Katoomba and all of Western Sydney.
