Are Huntsman Spiders Dangerous?
Huntsman spiders are one of the most well-known and easily recognized spider species in Australia. With their long legs, flattened bodies, and incredibly fast movements, they often startle homeowners when spotted on walls, ceilings, or quickly running across the floor. Their large size alone is enough to make many people uneasy, leading to the common concern: are huntsman spiders dangerous?
In reality, huntsman spiders are not considered dangerous to humans. Although their appearance may look intimidating, they are generally harmless and prefer to avoid confrontation. These spiders are not aggressive and will usually run away rather than attempt to bite. Even in the rare case of a bite, symptoms are typically mild and short-lived.
Huntsman spiders also play a beneficial role in the environment. They help control insect populations by feeding on cockroaches, flies, and other pests commonly found around homes. Instead of being a threat, they actually contribute to natural pest management.
By learning more about their behaviour, venom, and habits, homeowners can replace fear with understanding. With accurate information, it becomes easier to appreciate these large but mostly harmless spiders rather than panic at their presence.
Where Do Huntsman Spiders Live?
Huntsman spiders thrive in warm climates and are highly adapted to environments that provide shelter and protection. They are commonly found hiding beneath loose tree bark, under rocks, inside woodpiles, and within natural crevices that offer shade and security. These protected spaces create ideal daytime resting spots while allowing easy access to prey at night. Their flat bodies and long legs enable them to squeeze into narrow gaps, making them particularly skilled at occupying tight, concealed areas.
In addition to natural habitats, huntsman spiders are often discovered inside buildings. They may take refuge in roof voids, wall cavities, garages, sheds, and even behind curtains or furniture. Homes provide warmth, protection from predators, and a reliable supply of insects, which makes them attractive hiding places.
Huntsman spiders are especially common in tropical and subtropical regions where higher temperatures and humidity support insect activity. In Australia, they are widely distributed across many states. During spider season in Australia, typically in the warmer months, sightings tend to increase as spiders become more active in search of food and shelter. While more prevalent in warm regions, they can also appear in temperate areas when seasonal conditions are favourable.
What Do Huntsman Spider Eats?
Huntsman spiders are nocturnal hunters, becoming most active after dark when many insects are on the move. They feed on a wide range of common household and outdoor pests, including cockroaches, moths, beetles, crickets, and other small insects. Rather than building webs to catch prey, huntsman spiders actively hunt, using their speed, strong legs, and excellent vision to track and capture insects efficiently.
Their broad diet and strong hunting ability make them highly effective natural pest controllers. By reducing populations of nuisance insects, they help maintain ecological balance both indoors and outdoors. In gardens, sheds, and even inside homes, huntsman spiders can contribute to controlling unwanted bug activity without the use of chemicals.
Although their large size can be intimidating, their presence often indicates an environment where insects are available as a food source. In many cases, they are quietly helping to manage other pest populations, making them beneficial predators within the ecosystem.
Can Huntsman Spider Bite?
Huntsman spiders can bite, but it is uncommon and usually happens only if they feel threatened or are accidentally handled. They are not aggressive toward humans and generally prefer to run away rather than defend themselves. If a bite does occur, it is typically mild and may cause temporary symptoms such as slight pain, redness, or swelling at the site. Serious reactions are extremely rare. Their venom is designed to immobilise insects, not to harm people. While their large size can be intimidating, huntsman spiders pose very little medical risk and are generally considered harmless to humans.
How To Get Rid Of A Huntsman Spiders
Have you ever tried sweeping away a huntsman spider with a broom? They’re incredibly fast, aren’t they? Sometimes they may even run up the broom handle—something most people would rather avoid. Before calling pest professionals, there are a few practical steps you can try to get rid of a Huntsman Spider safely and effectively.
Use a container and cardboard
If the spider is on a flat surface like a wall, place a clear container or jar over it. Carefully slide a piece of cardboard between the container and the wall, trapping the spider inside. You can then carry it outside and release it away from your home.
Apply natural repellents
Spiders dislike strong scents such as peppermint, eucalyptus, tea tree, or citrus oils. Mix 15–20 drops of essential oil with water in a spray bottle and apply it around entry points, cracks, and corners.
Keep your home clean and clutter-free
Regularly remove cobwebs and clean dark spaces like garages, attics, and closets. Reducing clutter limits hiding spots and lowers insect activity that attracts spiders.
Seal gaps and reduce moisture
Close off crevices, repair loose screens, and seal vents. Reducing excess moisture with proper ventilation or a dehumidifier also helps deter insects—and in turn, spiders.
Arrange a professional pest inspection and control service
Another fast and reliable option is to contact a qualified pest control specialist. A trained technician can assess the extent of the spider issue and recommend practical preventative measures to reduce future activity. With the right knowledge, tools, and experience, professionals can safely manage and control spider infestations in both homes and businesses.
Final Thoughts: Are Huntsman Spiders Dangerous?
In summary, huntsman spiders are not dangerous to people. Although their large size and sudden movements can be alarming, they are generally harmless and even helpful in reducing common household pests. By understanding their behaviour and role in the ecosystem, you can feel more at ease if you encounter one in your home.
