Identification
Physical Characteristics
Size: Females are larger, with a body length up to 25-30mm. Males are smaller, typically reaching 15-20mm.
Coloration: Highly variable, typically a cryptic pattern of grey, brown, and black with radiating stripes on the cephalothorax resembling the spokes of a wheel. The abdomen has a central dark stripe with fainter chevron patterns. The underside is often black or dark grey.
Key Features: The prominent two large eyes in the middle row, combined with the radiating pattern on the cephalothorax, are key identifiers. Their active, ground-hunting behavior, rather than building a web, also distinguishes them.
Biology & Lifecycle
Development & Reproduction
Reproduction Rate: Females typically produce one to two egg sacs per year, depending on conditions and mating success. Each sac can contain over 100 eggs.
Lifecycle Details
Egg Stage
After mating, the female constructs a large, spherical egg sac from white or bluish silk, which she attaches to her spinnerets and carries with her. This maternal care protects the eggs from predators and environmental hazards. She may carry the sac for several weeks until the spiderlings are ready to hatch.
Larval Stage
Technically, spiders have a post-embryonic or nymphal stage rather than a larval stage. Upon hatching, dozens to over a hundred tiny spiderlings emerge from the egg sac. They immediately climb onto their mother's back and abdomen, where she carries them for protection for another week or more. They do not feed during this time, subsisting on yolk reserves.
Pupal Stage
Spiders do not undergo a pupal stage. They grow through a series of molts, shedding their exoskeleton as they increase in size. Each molt is a vulnerable period.
Adult Stage
After dispersing from their mother's back, the spiderlings begin to hunt independently. They will molt several times over many months before reaching sexual maturity. The typical lifespan is around 1-2 years. Adult males wander in search of mates, while females are more sedentary, often staying near their burrow.
Reproduction Rate
Females typically produce one to two egg sacs per year, depending on conditions and mating success. Each sac can contain over 100 eggs.
Generations Per Year
Usually one generation is produced per year. Spiderlings that hatch in late summer or autumn will overwinter as juveniles and mature the following spring or summer.
Development Time
The complete development from egg to mature adult can take nearly a year, influenced heavily by temperature and food availability.
Seasonal Cycle
Mating typically occurs in spring and summer. Females are seen carrying egg sacs in summer and autumn, with spiderlings emerging before winter. Activity peaks during the warmer months.
Environmental Factors
Abundant prey, suitable shelter (leaf litter, rocks, burrows), and mild temperatures are key factors for a thriving population. Both drought and flooding can negatively impact their survival and reproductive success.
Habitat & Distribution
Preferred Habitats
- Suburban gardens and lawns with ample ground cover
- Open woodlands and dry sclerophyll forests

- Not a known vector for any human diseases. The risk of secondary bacterial infection from a bite wound exists if not kept clean, but this is true for any puncture wound.
Allergens and Respiratory Issues
No specific allergens are associated with this species. However, individuals with high sensitivity to insect or spider bites may experience more pronounced local reactions.
Contamination Risk
Extremely low. As a solitary hunter, it does not infest food products and poses no significant risk of contamination to surfaces or foodstuffs.
Vulnerable Populations
- Small children may experience more pain due to their size.
- Individuals with a known allergy to spider or insect venom may have a stronger reaction.
- Anyone attempting to handle the spider is at higher risk of a defensive bite.
Symptoms of Exposure
- Immediate, sharp pain at the bite site, similar to a bee sting.
- Localized redness, itching, and swelling around the bite area.
- Symptoms are typically transient, resolving within an hour to a day.
- In rare cases, mild systemic effects like nausea or headache have been reported, but are often attributed to anxiety.
- Always seek medical attention if symptoms are severe or persistent, or if an allergic reaction is suspected.
Transmission Methods
- Health impacts are solely due to the injection of venom through a defensive bite. There is no other method of transmission for any health-related issue.
Risk Severity
Low. The bite of a Garden Wolf Spider is considered non-lethal and not medically significant for the general population.

Detection & Signs
Visual Signs
- Direct sightings of large, fast-moving spiders on the ground, especially at night when using a flashlight.
- Females carrying a prominent white egg sac on their rear.
- Females with a multitude of tiny spiderlings covering their abdomen and cephalothorax.
- Finding individuals that have accidentally wandered into homes, garages, or sheds.
- This is not an 'infestation' species; sightings are of solitary individuals.
Physical Evidence
- Finding molted exoskeletons in sheltered areas like under pots or in corners of a garage.
- Shallow burrows or retreats under rocks or logs, sometimes with a thin silk lining.
- No webs are made, so the absence of webs around a large spider is a key clue.
- No fecal spotting or waste trails are noticeable.
Behavioral Signs
- Rapid movement across open ground, patios, or even interior floors at night.
- A defensive rearing-up posture if cornered.
- Quickly retreating to a hiding spot (under furniture, into a crack) when disturbed.
- Presence of prey insects disappearing from an area.
Seasonal Indicators
- Increased sightings of wandering males in spring and summer searching for mates.
- Females with egg sacs or young are most common in summer and autumn.
- Sightings decrease significantly in winter as they become less active.
Early Warning Signals
- The 'infestation' concept doesn't apply. The first sign is seeing a single spider.
- A healthy garden with plenty of insect life will naturally attract these predators.
- Finding one indoors suggests there may be a gap or opening they are using for entry.
Prevention
Sanitation Measures
- Reduce clutter in and around the home, especially in garages, sheds, and along foundations. This removes hiding spots.
- Keep firewood piles raised off the ground and away from the house.
- Regularly mow lawns and trim vegetation near the foundation to make the area less attractive.
- Inside, regular vacuuming of corners and under furniture can remove any wandering individuals.
- Control insect populations inside the home, as this removes a potential food source.
Exclusion Methods
- Seal cracks and crevices in the building's foundation and exterior walls.
- Install tight-fitting weather strips on the bottom of all exterior doors.
- Ensure all window and door screens are in good repair, without holes or tears.
- Cover vents and utility entry points with fine-gauge mesh screens.
- Check items being brought indoors (e.g., firewood, potted plants) for spiders.
Landscaping Tips
- Maintain a clear zone of at least 30-50cm around the house foundation, free of mulch, leaf litter, and dense vegetation.
- Choose plants that are less attractive to the insects that wolf spiders prey on.
- Avoid using thick layers of organic mulch right up against the house; use gravel or stone instead.
- Improve drainage to prevent overly moist areas that attract both insects and spiders.
- Relocate compost bins and rock piles away from the immediate vicinity of the house.
Monitoring Strategies
- Place sticky traps along walls in garages or basements to monitor for wandering spiders and other crawling pests.
- Conduct regular visual inspections of likely hiding spots around the property, such as under pot plants, outdoor furniture, and in meter boxes.
- Use a flashlight at night to scan patios and garden beds, as their eyes reflect light, making them easy to spot.
- Keep a log of sightings to determine if there are specific areas or times when they are more common.
Environmental Modification
- Switch outdoor lighting to yellow or sodium vapor bulbs, which are less attractive to the insects that spiders feed on.
- Reduce moisture and humidity in sub-floor areas and basements by using dehumidifiers or improving ventilation.
- By making the environment less hospitable to their insect prey, you make it less attractive to wolf spiders.
Control Methods
Professional Treatment Methods
Chemical Control
Professional chemical treatment is not recommended for wolf spiders. They are solitary and beneficial. Broad-spectrum insecticides can harm the local ecosystem and non-target species. A targeted barrier spray around the foundation might be used in extreme cases of frequent home entry, but exclusion is a better long-term solution.
Biological Control
Not applicable. This spider is the biological control agent.
Physical Control
Professional services would focus on identifying and sealing entry points (exclusion). This is the most effective and environmentally sound professional approach.
Integrated Approach
An Integrated Pest Management (IPM) approach would involve inspection, habitat modification (e.g., clearing vegetation), exclusion (sealing gaps), and monitoring. Chemical use would be a last resort and highly targeted.
DIY Treatment Options
Natural Remedies
The best 'remedy' is physical removal. Place a container over the spider, slide a piece of stiff paper underneath, and release it outside away from the house.
Home Made Traps
Sticky traps can catch wandering individuals indoors but are not an effective population control method. They are better for monitoring.
Deterrent Methods
Some people suggest peppermint oil or citrus sprays, but their effectiveness against large, determined spiders is unproven and requires constant reapplication. Physical barriers are far more reliable.
Mechanical Control
Using a 'spider catcher' tool, which has a long handle and bristles, allows for safe capture and release without getting close to the spider. Vacuuming is also an effective removal method for indoor sightings.
Treatment Effectiveness
Success Rate
Exclusion methods have a very high success rate (over 90%) for preventing indoor entry. Relocation has a 100% success rate for removing a single spider.
Timeframe
Sealing entry points provides immediate and long-lasting results. Relocation is instantaneous.
Follow Up Required
Annual inspection of seals and screens is recommended to ensure they remain intact.
Seasonal Considerations
Prevention efforts, like sealing gaps, are best done before the warmer months (spring/summer) when spider activity increases.
Application Techniques
- For exclusion: Applying caulk or sealant to all cracks wider than 2-3mm.
- For relocation: The 'cup and paper' method.
- For monitoring: Placing glue boards flush against walls in low-traffic areas like garages or basements.

Browse All ProvidersSeasonal Patterns
Spring Activity
Spiders emerge from their winter inactivity. Mating season begins, and males become highly active, wandering extensively in search of females. This is a peak time for accidental indoor encounters.
Summer Activity
This is the peak activity period for hunting, growth, and reproduction. Females can be found carrying their prominent egg sacs. High temperatures may cause them to seek cooler shelters, sometimes near or in homes.
Autumn Activity
Spiderlings hatch and disperse. Females may produce a second brood if conditions are favorable. As temperatures cool, spiders may begin to seek out sheltered locations to overwinter, which can again lead to indoor entry.
Winter Activity
Activity slows dramatically. They enter a state of dormancy or reduced activity, hiding in their burrows or deep within leaf litter and under logs to survive the cold. Sightings are rare.
Breeding Season
Primarily late spring through summer.
Peak Activity Period
The concept of 'infestation' doesn't apply, but peak indoor sightings occur in spring (wandering males) and autumn (spiders seeking shelter).
Environmental Factors
Temperature Effects
Warm weather increases metabolic rate, hunting activity, and development speed. Cold weather triggers dormancy.
Humidity Effects
High humidity is generally favorable, but they are adaptable. Extreme drought may force them to seek moist microclimates, such as irrigated gardens or inside homes.
Photoperiod Effects
Their nocturnal behavior is strongly tied to the light-dark cycle.
Weather Patterns
Heavy rain can flood their ground-level shelters, forcing them to move to higher ground and potentially into human structures.

Compliance Requirements
- No specific compliance requirements for this species.
- Adherence to the Australian Pesticides and Veterinary Medicines Authority (APVMA) regulations is required if any chemical treatment is performed.
Frequently Asked Questions
What makes the Garden Wolf Spider different from other spider species?
The Garden Wolf Spider (*Tasmanicosa godeffroyi*) is unique for several reasons. Its most definitive feature is its eye arrangement: eight eyes in three rows, with two exceptionally large, forward-facing eyes in the middle row that give it superb vision for hunting. Unlike many spiders, it doesn’t build a web to catch food. Instead, it’s an active, agile hunter that runs down its prey on the ground at night. Another remarkable characteristic is its maternal care. The female attaches her large, spherical egg sac to her spinnerets and carries it everywhere until the eggs hatch. Afterwards, the spiderlings climb onto her back, and she carries them for a week or more, protecting them from predators. This combination of being a large, fast-moving ground hunter with a distinctive eye pattern and unique parenting behavior clearly separates it from web-builders, ambush predators like the Huntsman, and highly venomous spiders like the Funnel-web. Its cryptic grey-and-brown coloration with a 'Union Jack' pattern on its cephalothorax is also a key identifier.
How dangerous is a Garden Wolf Spider to humans?
The Garden Wolf Spider is not considered a dangerous species. Its venom is of low risk (non-toxic) to humans. A bite from one is rare and typically only happens as a last-ditch defense if the spider is accidentally trapped against skin or handled roughly. If a bite does occur, it is usually accompanied by immediate, sharp pain, comparable to a bee or wasp sting. The site may become red, itchy, and slightly swollen. These local symptoms are generally short-lived, resolving within a few hours to a day without any lasting effects. Systemic symptoms like nausea or headaches are very rare and often linked more to the shock or anxiety of being bitten than the venom itself. There have been no recorded fatalities from a wolf spider bite. While the bite can be painful, it is not medically significant for the vast majority of people. Standard first aid involves cleaning the area with soap and water and applying a cold pack to reduce pain and swelling. Medical attention is only necessary if symptoms are severe, persist, or if the person has a known, specific allergy to spider venom, which is very uncommon.
What is the most effective way to get rid of Garden Wolf Spiders?
The most effective and recommended approach is not 'getting rid of them' in the sense of extermination, but managing their presence. These spiders are beneficial predators in the garden. For individuals that wander indoors, the best method is safe, physical removal. Place a jar or container over the spider, slide a piece of cardboard underneath to trap it, and then release it outside, away from the house. To prevent them from coming inside in the first place, focus on exclusion. This involves a thorough inspection of your home's exterior to find and seal any cracks, gaps, or holes in the foundation, walls, and around pipes or vents. Installing weather strips under doors and ensuring window screens are in good repair is crucial. Chemical treatments are strongly discouraged. They are unnecessary, ineffective against solitary wanderers, and can harm beneficial insects, pets, and the local ecosystem. If you feel you have an unusual number of spiders entering your home, the most effective professional service would be one that focuses on identifying and sealing these entry points, not spraying pesticides.
How can I prevent Garden Wolf Spiders from returning?
Long-term prevention focuses on making your home and its immediate surroundings less attractive and accessible to them. The single most important step is exclusion: meticulously sealing all potential entry points into your house. This is a permanent solution. Secondly, modify the habitat right outside your home. Maintain a clear buffer zone of about 50cm around your foundation, free from leaf litter, mulch, and dense vegetation, as this removes their primary hiding spots near the house. Keep your lawn mowed and gardens tidy. Store firewood on a rack off the ground and away from the house. Reduce outdoor lighting or use yellow bulbs, which attract fewer insects—the spiders' food source. Inside, reduce clutter in garages, basements, and storage areas to eliminate potential hiding places. By removing access, shelter, and food, you create an environment that naturally discourages wolf spiders from wandering into your living spaces. Regular monitoring with sticky traps in garages can also alert you to their presence and potential new entry points.
When is the Garden Wolf Spider most active during the year?
The Garden Wolf Spider's activity is strongly tied to the seasons. It is most active during the warmer months, from spring through autumn. In spring, as temperatures rise, they emerge from their overwintering shelters. This is a key mating period, and males become particularly active, wandering long distances at night in search of females, which is why indoor sightings often peak at this time. Activity remains high throughout the summer, which is their main period for hunting and growth. Females are often seen carrying egg sacs or spiderlings during mid to late summer. In autumn, activity continues, but as temperatures drop, they begin to seek sheltered places to survive the winter, which can lead to another, smaller peak in indoor encounters. During winter, they become largely inactive, hiding in burrows or under debris in a state of dormancy. Therefore, you are most likely to encounter an active Garden Wolf Spider on a warm evening between September and May.
