 As the summer sun starts to heat up across Sydney, it’s not just the locals who come out to enjoy the silly season. Spiders, often hidden and unnoticed, become more active and visible. Understanding these eight-legged inhabitants is crucial for homeowners and business operators alike. In this comprehensive guide, we delve into the world of spiders in Sydney, addressing common concerns and offering expert advice on managing them effectively.
Types of Spiders in Sydney Sydney hosts a variety of spider species, each with its own unique traits. Understanding their distinctive features, nesting habits, and how venomous they are, will help you manage any spider sightings or infestations within your Sydney home or business. Sydney Funnel-Web Spider - Funnel web spiders are highly venomous; one of the most dangerous spiders in the world. With males having a higher venom toxicity and often being far more aggressive than females. - Females generally grow up to 35mm, and males around 25mm. They have large, bulky, glossy black bodies, and powerful fangs. - Sydney Funnel-Webs like moist, cool environments and are often in suburban gardens. Look for their distinctive funnel-shaped webs in sheltered, ground-level locations. Redback Spider - Redbacks’ venom contains a potent neurotoxin, which can be fatal. Any bites should be seen to by a medical professional immediately. - They are distinguishable by their black bodies with a prominent red stripe on the back. Females are typically about 1cm in body length, while males are significantly smaller. - Redback spiders prefer dry, dark, sheltered places like sheds, under seats, and amongst rubbish. But these spiders will rarely leave their web, so your chances of being bitten are quite low. Huntsman Spider - Huntsmans are mildly venomous but not harmful to humans. However, their bite can still be painful and result in swelling, itchiness and occasionally feeling unwell. - Flat-bodied, fast-moving, and brownish in colour, huntsman spiders are large, with a leg span up to 15 cm. But despite their size, they are generally harmless and help control insect populations. - They are typically found under loose bark on trees, under rocks, and within homes. Keep an eye out for babies on walls and ceilings. White-Tailed Spider - Bites can cause discomfort and mild illness, but not considered dangerous to humans. - White tails will grow to about 18-20mm in length and have a dark reddish-grey body with a distinctive white tip at the end. - They wander in homes, under bark, among leaves and in sheds, and their diet mainly consists of other spiders. Black House Spider - The black house spider is considered venomous but not lethal, where bites may cause nausea and sweating. However, they are shy and often retreat when disturbed. - With a dark brown to black velvet-textured appearance, females grow up to 18mm and males around 9mm. - Commonly found in window frames, brickwork, and eaves of houses. Look for their messy webs with funnel-like entrances. Garden Orb-Weaving Spider - Orb spiders can be mildly venomous but are relatively non-aggressive and harmless to humans. - They’re often sporting a bulbous abdomen with colourful patterns. Females can be up to 30mm in length, while males are much smaller. - Found mostly in gardens, constructing large, circular, vertical webs. Look for their webs in the evenings (when they typically rebuild webs), often spanning between plants. Problems Caused by Spiders Health Risks If you disturb a spider or its web, it may choose to retaliate by biting. While many spider varietals have a non-toxic venom and their bites are largely benign, some venomous bites can lead to allergic reactions, infections, and in rare cases, severe medical conditions. Psychological Effects The presence of spiders can cause anxiety and fear, particularly in individuals with arachnophobia. Making for a stressful home or working environment. Hygiene Issues Webs and droppings can create a mess, attracting other pests and creating a perception of poor cleanliness. The accumulation of webs over time can become difficult to clean and trigger allergies in some individuals. Property Damage Some spiders, like the Black House Spider, can cause minor damage to structures through their webbing and nesting habits. Spraying or removing them as early as possible can prevent further widespread damage. Signs of a Spider Infestation These are a list of the most obvious signs of spider infestation within your Sydney home or business. Webbing – Increased web activity, especially in corners and less-disturbed areas. Sightings – Frequent encounters with live or dead spiders. Droppings – Small, dark spots, often a sign of a feeding site. Egg Sacs – Silk-wrapped bundles indicative of a breeding population. Nocturnal Activity – Increased spider visibility at night. Unusual Insect Activity – An uptick in prey insects can indicate spider presence. Shed Skins – Finding discarded skins as spiders grow. Audible Noises – Some species, like Huntsman, can produce noise, especially in quiet environments. How to Prevent Spider Outbreaks The best form of treatment is often prevention – and the same holds true for managing spider infestations. Whether you’re a Sydney homeowner or businessowner, implementing some or all of the following strategies can minimise the likelihood of having uninvited creepy crawlies invade your space. Seal Cracks and Openings Blocking entry points prevents spiders from entering. This includes fixing screens, sealing gaps around doors and windows, and repairing cracks in walls. Regular Cleaning Reduces hiding spots and removes webs and egg sacs. Focus on dusting and vacuuming hard-to-reach areas. Control Humidity Using dehumidifiers in damp areas makes them less hospitable for moisture-loving spiders. Light Management Outdoor lighting attracts insects, which in turn attract spiders. Using yellow-tinted bulbs can reduce this attraction. Vegetation Control Overgrown vegetation can provide shelter for spiders. Keeping the garden tidy and trimming plants away from the house helps. Proper Storage Store items in sealed containers to prevent spiders from taking residence. Natural Deterrents Certain scents, like peppermint oil, can repel spiders. Avoid Outdoor Lights Minimising outdoor lighting reduces the insect population, indirectly reducing spider presence. Regular Inspections Periodic checks help identify early signs of infestation. Pest Control Regular pest control treatments can deter spiders from establishing themselves. Educate Household Members Knowing how to identify spiders and their signs can help in early detection and prevention. Professional Consultation For recurring problems, consulting a pest control expert can provide customised solutions. Spider Outbreaks in Businesses Spiders can pose a range of health, hygiene, stress and property damage risks to your business, and its employees and customers. Hospitality Sector Nothing deters guests like the unwanted surprise of a spider repelling from the ceiling or hiding in the bathroom. The presence of spiders can have a lasting impact on the business’s reputation. With poor reviews and customers reluctant to return. Retail Spiders, especially in customer-facing areas, can lead to negative customer experiences and affect the brand reputation of your retail business. Not to mention damage to stock that is then unable to be sold or needs to be sold at a significant discount. Warehouses and Storage Facilities Spiders can contaminate goods, and in some cases, spider infestations can cause health hazards to staff and cause considerable product damage. Businesses managing these types of facilities need to be hyper-vigilant, as these are ideal environments for many spider species. Offices Spider infestations within an office environment can evoke feelings of uncleanliness and poor hygiene. Employee morale and productivity can be affected, and in severe cases, it might lead to health and safety concerns.
