Do huntsman spiders bite humans?

Huntsman spiders are one of the most recognisable spiders found in Australian homes. Their large size and long legs can be surprising when they appear on walls, ceilings, or inside garages. Many homeowners ask the same question when they see one indoors: Do huntsman spiders bite humans?

In most situations, huntsman spiders avoid contact with people. While a huntsman spider is capable of biting, bites are uncommon and usually occur only when the spider feels threatened or is handled.

Understanding huntsman spider behaviour can help homeowners recognise when these spiders may appear around the home and when pest control may be needed.

What are huntsman spiders?

Huntsman spiders are large, fast moving spiders commonly found throughout Australia. They belong to the Sparassidae family and are known for their wide, flat bodies and long legs.

Unlike some other spiders, huntsman spiders do not build webs to catch prey. Instead, they actively hunt insects and other small pests.

Huntsman spiders are often found in:

• Gardens and outdoor walls
• Under loose bark on trees
• Garages and sheds
• Behind picture frames
• Inside roof spaces
• On interior walls or ceilings

Because huntsman spiders prefer sheltered areas, they may occasionally move indoors.

Do huntsman spiders bite humans?

Yes, huntsman spiders can bite humans, but bites are rare. Huntsman spiders usually avoid people and prefer to escape rather than defend themselves.

Most bites occur when the spider is accidentally pressed against the skin, trapped in clothing, or handled.

A huntsman spider bite may cause:

• Mild local pain
• Redness or swelling around the bite area
• Temporary discomfort

Serious reactions are uncommon. However, any spider bite that causes strong pain or unusual symptoms should be assessed by a medical professional.

Are huntsman spiders dangerous?

Huntsman spiders are generally not considered dangerous to humans. Their venom is not regarded as medically significant for most people.

Although their size can be intimidating, huntsman spiders typically avoid confrontation. They are fast runners and often move away quickly when disturbed.

In many situations, huntsman spiders remain hidden in quiet areas of the home and may only be noticed occasionally.

Why do huntsman spiders enter homes?

Huntsman spiders often enter homes searching for shelter or prey. Indoor environments can provide hiding places and a steady supply of insects.

Common reasons huntsman spiders appear indoors include:

• Warm shelter during weather changes
• Access to insects such as flies or cockroaches
• Open doors or windows
• Gaps around roof spaces or wall cavities
• Outdoor lighting that attracts insects

When insects gather near windows or lights, huntsman spiders may follow their food source indoors.

Where do huntsman spiders hide inside homes?

Huntsman spiders prefer quiet and sheltered spaces where they can remain undisturbed during the day.

Common hiding places include:

• Behind furniture
• Inside cupboards or storage areas
• Under loose wall fittings
• Behind curtains
• Inside garages or sheds
• Under roof tiles or in ceiling spaces

Because huntsman spiders move quickly, they may suddenly appear on walls or ceilings when searching for insects.

Signs of huntsman spider activity around your home

Huntsman spiders do not usually create webs, so their presence may be noticed only when the spider is seen directly.

However, several signs may indicate huntsman spider activity nearby:

• Large spiders appearing on walls or ceilings
• Spider egg sacs in sheltered areas
• Increased insect activity around lights
• Spiders appearing in garages or storage spaces

Outdoor vegetation close to buildings can also support insect populations that attract huntsman spiders.

How to reduce huntsman spiders around your home

Reducing the conditions that attract insects can help reduce huntsman spider activity.

Homeowners can take practical steps such as:

• Keeping doors and windows sealed with screens
• Reducing outdoor lighting that attracts insects
• Removing clutter in garages and storage areas
• Trimming vegetation close to exterior walls
• Cleaning outdoor areas where insects gather

These steps help reduce the insect populations that huntsman spiders feed on.

When should you consider pest control for huntsman spiders?

Seeing an occasional huntsman spider may not always require pest control. However, frequent spider sightings indoors may indicate favourable conditions around the property.

Professional spider control may be helpful when:

• Large spiders appear regularly inside the home
• Spider activity increases in garages or storage areas
• Insect activity around the home attracts spiders
• Spider egg sacs are found around the property

A professional pest control inspection can help identify the areas where spiders may be entering or hiding.

Rentokil technicians provide pest control services for spiders in Australian homes and businesses. A professional inspection helps identify spider activity and the conditions that attract insects and spiders to the property.
