Frequently Asked Questions
Common questions about Sugar Glider
Are Sugar Glider dangerous?
Sugar Gliders are not dangerous to humans but can cause property damage by nesting in roof spaces.
How do I identify Sugar Glider?
Look for grey fur, dark stripe, large eyes, and a gliding membrane extending from wrist to ankle.
How do I control Sugar Glider?
Use exclusion methods like sealing entry points and installing possum boxes as alternative nesting sites.
How do I identify a sugar glider in my home?
Sugar Gliders and Krefft's Gliders are small, grey marsupials (12–13 cm long) with large ears, large dark eyes, a long fluffy tail, and a distinctive gliding membrane (patagium) stretched between front and hind legs. The two species are visually very similar and cannot be reliably distinguished without expert examination. If inside your home, you may hear rapid scampering, high-pitched chirping, and chattering vocalisations at night. Unlike possums, gliders are much smaller and more agile. If you spot a glider indoors, do not attempt to trap or handle it; contact WIRES NSW (1300 094 737) or your state wildlife rescue service immediately for safe, lawful guidance.
Are sugar gliders dangerous in Australia?
No. Sugar Gliders and Krefft's Gliders are completely harmless to humans; they are non-aggressive, do not bite unprovoked, and carry no disease known to be transmissible to people. Both species are protected native wildlife under the EPBC Act 1999 and state wildlife laws, so harm, killing, or unauthorised relocation is illegal and carries severe penalties. The primary concern for residents is nocturnal noise if gliders are nesting in roof voids, which is best managed through humane one-way exclusion and habitat enhancement. If a glider enters your home, contact a licensed wildlife rescue organisation for safe removal — the animal poses no safety risk.
How much does sugar glider control cost in Australia?
Sugar Gliders and Krefft's Gliders cannot legally be controlled, killed, or removed as pests in Australia. Humane exclusion services — one-way exit devices, sealing entry points, habitat management — are available from AEPMA-accredited wildlife-friendly pest control businesses and licensed wildlife rescue organisations. Contact WIRES NSW (1300 094 737), Wildlife Victoria (1300 094 535), or your local RSPCA wildlife service for cost estimates and referrals to accredited operators. Prevention through sealing roof voids, trimming branches, and installing nest boxes is the most cost-effective and humane long-term approach.
When are sugar gliders most active in Australia?
Sugar Gliders and Krefft's Gliders are strictly nocturnal, sleeping during the day in nests inside tree hollows and becoming most active at night. Peak activity occurs shortly after sunset and again just before sunrise, driven by foraging for nectar, pollen, seeds, and insects. This pattern is consistent year-round; there is no seasonal variation in nocturnal activity timing. If you hear scampering, chirping, or chattering in roof voids or ceilings during the evening and night, nocturnal gliders are likely present.
Should I call a professional for sugar gliders in my home?
Yes. If you suspect Sugar Gliders or Krefft's Gliders are in your roof, ceiling, or other interior spaces, contact a licensed wildlife rescue organisation immediately — WIRES NSW (1300 094 737), Wildlife Victoria (1300 094 535), or your state's RSPCA wildlife service. Do not attempt trapping, any form of lethal control, or DIY exclusion without professional guidance; both species are protected under the EPBC Act 1999 and state legislation, and unauthorised handling is illegal. Licensed wildlife rescue specialists will safely confirm the species, use humane one-way exclusion to allow safe exit, seal entry points permanently, and advise on habitat management (nest boxes, tree planting) to prevent future conflicts. If an animal is injured or orphaned, these organisations can also arrange specialist veterinary care.
