Bogong moth swarms are once again filling the skies over New South Wales and beyond as the endangered insects begin their annual migration to the Australian Alps. With reports surging past last year's totals, many homeowners are wondering how to safely remove these precious moths from their homes. Understanding the reasons behind the boom and the right removal techniques is essential for protecting both your property and this vulnerable species.
Why Are Bogong Moth Numbers Booming in 2026?
The recent surge in bogong moth sightings is largely due to favourable weather conditions. Wetter, cooler springs in their breeding grounds across southern Queensland, NSW, the ACT, and parts of Victoria and South Australia have led to higher survival rates of eggs and larvae. Dr Marissa Parrott, a reproductive biologist at Zoos Victoria, explains that the moths migrate up to 1,000 km to cool caves in the Australian Alps to escape the summer heat. After a catastrophic population collapse between 2017 and 2019 – when numbers dropped by up to 99.5% – these increased sightings are a hopeful sign of recovery.
What to Do If You Find Bogong Moths Inside Your Home
Bogong moths are harmless to humans and pets, but they can be a nuisance when they enter homes in large numbers. They are attracted to light, so keeping windows and doors closed at night or using curtains to block indoor light can reduce entry. If you do find them inside, avoid using insecticides, as these can harm the moths and other beneficial insects. Instead, gently coax them into a container or use a soft brush to guide them outside. Releasing them after dusk, away from bright lights, gives them the best chance to continue their migration.
Safe Removal Techniques Compared
| Method | Effectiveness | Safety for Moths | Ease of Use |
|---|---|---|---|
| Container and paper | High | High | Moderate |
| Soft brush | Moderate | High | Easy |
| Vacuum (low suction) | High | Low | Easy |
| Insecticide | High | None | Easy |
Key Takeaways for Coexisting with Bogong Moths

- Gentle removal: Use a container or soft brush to relocate moths without harm.
- Avoid chemicals: Insecticides can kill moths and disrupt local ecosystems.
- Report sightings: Contribute to citizen science via Moth Tracker to aid conservation.
