Huntsman spiders are one of Australia’s most well-known and widespread species of spiders. While their large size and rapid movements may startle people, many wonder whether these spiders pose a danger to humans. In this article, we will address common questions about huntsman spiders, including whether their bites are dangerous, their appearance, and how to manage an infestation.
Huntsman spiders, belonging to the family Sparassidae, are commonly found in homes, gardens, and forests across Australia. These spiders are named for their hunting style, as they actively hunt and chase down their prey rather than spinning webs. Huntsman spiders are particularly known for their large size, long legs, and quick movements, which can sometimes be alarming to people who encounter them unexpectedly.
Huntsman spiders are generally not aggressive and prefer to avoid human contact. However, if threatened or cornered, they may bite in self-defence. While they can be intimidating due to their size, huntsman spiders are generally harmless to humans.
Huntsman spiders are large, with some species reaching a leg span of up to 15 cm. They are flat, brown or grey in colour and often have a distinctive pattern of light and dark markings on their bodies. Their long, spindly legs resemble those of a crab, which is why they are sometimes called “giant crab spiders.”
Their flat bodies allow them to hide easily in tight spaces, such as behind furniture or under rocks. Huntsman spiders are fast movers, and they can scurry quickly across walls, floors, or ceilings when startled. They are generally nocturnal and prefer to remain hidden during the day, coming out at night to hunt for food.
Yes, huntsman spiders can bite, but they do so only in self-defence when they feel threatened or cornered. Huntsman spider bites are relatively rare because these spiders are not naturally aggressive. Most of the time, huntsman spiders will try to escape from humans rather than confront them.
If you do get bitten by a huntsman spider, the bite is usually harmless and may cause mild symptoms. However, it’s essential to recognise that some individuals may experience more severe reactions to the venom.
Huntsman spider bites are not considered dangerous to humans. While the venom can cause temporary symptoms, these bites generally cause only mild discomfort. Symptoms of a huntsman spider bite can include:
Pain and redness: The bite site will likely become red, swollen, and sore, much like a bee sting.
Itching: Some individuals may experience itching around the bite area.
Swelling: The affected area may swell up, but the swelling usually goes down within a few hours.
Localised irritation: In rare cases, people may experience mild irritation, which can last for a day or two.
In extremely rare cases, individuals may experience more severe symptoms such as dizziness, nausea, or headache, but these reactions are not common. If the bite site shows signs of infection or if the symptoms worsen, seek medical attention immediately.
If a huntsman spider bites you, the first step is to stay calm. Follow these first aid steps to treat the bite:
Clean the Bite Area: Gently wash the bite site with soap and water to reduce the risk of infection.
Apply a cold compress: Use a cold compress or ice wrapped in a cloth to reduce swelling and relieve pain.
Take pain relief: If you experience pain or swelling, you can take over-the-counter pain relievers, such as paracetamol or ibuprofen, to alleviate the symptoms.
Monitor for symptoms: Although most bites will resolve on their own, keep an eye on the affected area for signs of infection, such as pus or increased redness. If the symptoms worsen or you experience any unusual reactions, seek medical attention immediately.
Keep the bite elevated: If possible, elevate the affected limb to help reduce swelling.
In the vast majority of cases, huntsman spider bites are not serious and will heal without medical intervention.
Yes, huntsman spiders do possess venom, but their venom is not dangerous to humans. The venom is used primarily to subdue and immobilise their prey, which typically consists of insects and small invertebrates. While the venom is potent enough to incapacitate their prey, it is not strong enough to cause serious harm to humans.
Although huntsman spiders are venomous, their venom is not toxic to humans, and their bites are not life-threatening. In fact, huntsman spiders are beneficial to have around, as they help control populations of other pests, such as mosquitoes, cockroaches, and flies.
Huntsman spiders are generally not aggressive towards humans. They are not known to seek out confrontation and will typically only bite if they feel threatened, provoked, or cornered. Huntsman spiders are more likely to run away and hide than to engage in an attack.
These spiders are shy by nature and prefer to remain out of sight during the day, often hiding in dark, sheltered areas such as under furniture, behind curtains, or in cracks in the walls. They are more active at night, when they hunt for food, but they generally avoid human interaction as much as possible.
If you encounter a huntsman spider in your home and would like to remove it, there are several safe methods you can use:
Use a glass and paper: One of the safest ways to remove a huntsman spider is to coax it into a glass or container gently, and then carefully slide a piece of paper under the spider to lift it. Once contained, you can relocate the spider outside.
Call pest control: If you have a large number of huntsman spiders in your home or feel uncomfortable removing them yourself, it’s a good idea to call a professional pest control service. They can safely handle the removal and advise you on preventative measures to keep your home protected from spiders.
Seal entry points: To prevent huntsman spiders from entering your home, seal any cracks or gaps in windows, doors, and walls. Installing screens on windows can also help keep spiders out.
Reduce clutter: Huntsman spiders prefer hiding in dark, cluttered spaces. Keeping your home clean and uncluttered will reduce the number of places where spiders can hide.
Regular inspections: Periodically inspect areas such as basements, attics, and behind furniture for any signs of spiders. Early detection can help you address the problem before it worsens.
Huntsman spiders, while large and fast-moving, are not dangerous to humans. Their venom is not potent enough to cause harm, and bites are typically mild and short-lived. While their size can be intimidating, huntsman spiders are generally harmless and can be considered helpful neighbours due to their role in controlling insects, according to Australian Geographic. These spiders are usually shy and avoid human contact, and they play a valuable role in controlling household pests.
If you encounter a huntsman spider in your home, the best course of action is to remain calm and carefully relocate it outside. By taking simple steps to keep your home clean and sealing entry points, you can prevent huntsman spiders from becoming a problem in the first place. With proper precautions, huntsman spiders can coexist with humans without posing a threat.
