Wasp control Melbourne

Wasp nest removal in Melbourne typically costs between $180 and $380 depending on species, nest size, and location. Paper wasp nests on accessible outdoor structures start from $180. European wasp nests in wall cavities, roof voids, or underground cost more due to the higher risk and equipment required, typically $250 to $380+. Same-day treatment is available across most Melbourne suburbs.

European wasps (Vespula germanica) are bee-sized (12–17mm), bright yellow with bold black markings, and build large enclosed papery nests inside wall cavities, underground, and in roof voids. A mature colony can contain thousands of workers. They swarm aggressively if disturbed and can sting multiple times. Paper wasps (Polistes species) are longer and more slender (17–25mm), build open umbrella-shaped honeycomb nests on eaves and outdoor structures, and have smaller colonies. They are less aggressive at a distance but will sting if the nest is touched.

Small paper wasp nests on accessible outdoor structures can sometimes be managed DIY at night with full protective clothing, but it carries risk. European wasp nests should never be approached without professional protective equipment. A disturbed European wasp nest can result in hundreds to thousands of stings. People with wasp venom allergies face anaphylaxis risk, a potentially life-threatening reaction. For any nest inside a wall cavity, underground, or within the building structure, call a professional regardless of species.

Same-day wasp nest treatment is available across most Melbourne suburbs. Treatment is most safely carried out at dusk when wasp activity is lowest. Paper wasp nests are typically eliminated in a single visit. European wasp nests require 24 to 48 hours after treatment for full colony elimination as the insecticide spreads through the nest via returning workers.

Worker wasps returning to the nest die on contact with the insecticide over the 24 to 48 hours following treatment. Paper wasp nests can usually be physically removed once activity has ceased, typically 24 hours after treatment. European wasp nests inside wall cavities or underground are usually left in place once eliminated, as removal would require destructive access. The nest will not be reused the following season.

European wasp colonies establish in spring (September to November) when a new queen starts a fresh nest after winter. The colony grows through summer, reaching its largest and most dangerous size in late summer and autumn (February to April) when the vast majority of Melbourne wasp sting incidents occur. Treating a nest in spring when the colony is small is significantly safer and more cost-effective than waiting until late summer. By winter, most colonies die off in Melbourne's climate, with queens overwintering to establish new nests the following spring.
