Overview of the Most Common Spiders in the Central Coast
The Central Coast is home to a diverse array of spider species, each with unique characteristics and behaviours. Here, we introduce some of the most common spiders you might encounter in the region. This overview provides a snapshot of their appearance, web structure, and other interesting facts, laying the groundwork for a deeper understanding of these fascinating arachnids.
- Daddy-Long-Legs: The Daddy-Long-Legs, easily recognized by its extremely long, thin legs and small body, is a frequent visitor in homes, particularly in sheds and garages. Contrary to popular belief, they are not highly venomous to humans. Their webs are often messy and irregular, adding a sense of eeriness to dark corners.
- Huntsman Spider: The Huntsman is a large, brown spider known for its speed and agility. It is often seen running across walls and ceilings, causing alarm due to its size. Despite their intimidating appearance, huntsman spiders are not considered dangerous to humans and rarely bite.
- Funnel Web: Funnel-web spiders are among the more dangerous species found in the Central Coast. They create distinctive funnel-shaped webs, serving as burrows and traps for prey. These spiders should be approached with caution, as their bites can be medically significant. The australian Reptile Park at Somersby collects Funnel web venom to help in producing the antivenom for bites.
- Redback: Small yet notorious, the Redback spider is identified by its black body and characteristic red stripe. They prefer urban areas, building their webs in sheltered locations. While their venom is potent, effective antivenoms have made serious incidents rare.
- White-tailed Spider: The White-tailed spider, marked by a white spot on its back, is often found in houses and gardens. There is a myth that their bites cause severe skin ulceration, but this has been largely debunked by recent research.
- Orb-Weaver Spider: Orb-Weavers are known for their impressive, large, spiral-shaped webs. These spiders play an important role in controlling insect populations and are generally harmless to humans.
- Black House Spider: The Black House Spider, often mistaken for the more dangerous Funnel Web, has a dark, matte appearance and builds dense, funnel-shaped webs. They are commonly found around human habitations, particularly near windows and doors.
- Wolf Spider: Wolf spiders are ground dwellers, recognised by their greyish-brown colour and hairy body. They do not build webs, instead hunting their prey actively. Female wolf spiders are known for carrying their egg sacs and young on their back, a unique and fascinating behaviour.
In the next sections, we will explore each of these spiders in more detail, discussing their habitats, danger levels, and what you can do to manage their presence around your property.
Exploring Central Coast's Common Spiders
Get to know the common spiders found in the Central Coast through an in-depth look at their unique traits. We will provide detailed information on their appearance, web characteristics, the level of danger they pose, and how best to manage their presence.
Appearance: The Daddy-Long-Legs spider is known for its distinctive long, thin legs and small body, giving it a fragile appearance. The body is typically no larger than a pea, but the legs can extend several centimetres, creating a stark contrast between body and limb size.
Web: Their webs are often messy and irregular, lacking the symmetry or pattern found in other spider webs. You'll commonly find them in undisturbed areas like sheds, garages, and attics. The web is not used to catch prey but rather as a retreat.
Danger Level and Bite: Despite myths suggesting otherwise, Daddy-Long-Legs spiders are not dangerous to humans. Their fangs are capable of piercing human skin, but their venom is not harmful to people. Bites are extremely rare and typically result in no more than minor irritation.
Treatment: Managing their presence mainly involves regular cleaning and removal of webs from corners and less-visited areas of your property. Ensuring these areas are well-lit and less cluttered can also discourage them from settling in.
Appearance: Huntsman spiders are large, with some species reaching leg spans of up to 15 cm. They are usually brown or grey with a flat body, allowing them to squeeze into narrow spaces. Their size can be intimidating, but they play an important role in controlling insect populations.
Web: Huntsman spiders do not build webs. Instead, they are free-roaming, nocturnal hunters, often seen on walls and ceilings. They prefer to live under bark, crevices, or other sheltered spaces during the day.
Danger Level and Bite: While they appear formidable, huntsman spiders are not considered dangerous to humans. They are reluctant to bite, and if they do, their venom is not lethal. A bite may result in temporary pain, swelling, or nausea. In the rare case of a severe reaction, medical advice should be sought.
Treatment: To prevent huntsman spiders from entering your home, seal cracks and crevices in walls, doors, and window frames. Reduce outdoor lighting that attracts insects, their primary food source. If you encounter a huntsman spider indoors, calmly guide it towards an exit using a broom or a piece of cardboard.
Appearance: Funnel Web spiders are known for their robust build and glossy black or dark brown colour. Males are typically smaller and more slender than females. Their large fangs and aggressive stance when threatened are distinctive characteristics.
Web: These spiders construct dense, silk funnel-shaped webs, which serve as both a retreat and a trap for prey. The webs are often found in moist, cool, sheltered areas like under rocks, in crevices, or in burrows in the ground.
Danger Level and Bite: Funnel Web spiders are among the most dangerous spiders in the world. Their venom can be life-threatening to humans, especially without prompt medical treatment. Symptoms of a bite can include severe pain, sweating, nausea, and in severe cases, respiratory distress or coma.
Treatment: Caution is paramount when dealing with Funnel Web spiders. To prevent encounters, avoid handling garden debris with bare hands, wear gloves when gardening, and check shoes before wearing them. If a Funnel Web spider is found, it is advisable to contact professional pest control services for safe removal.
Appearance: The Redback spider is small, with females measuring about 1 cm in body length. They are predominantly black with a prominent red or orange stripe on the upper side of their abdomen and an hourglass-shaped mark underneath.
Web: Redbacks build irregular, sticky webs in dry, sheltered sites such as under rocks, in logs, sheds, junk piles, and even in outdoor toilets. The web includes a funnel where the spider hides, and a sticky catching area.
Danger Level and Bite: Redback spider bites are a serious medical concern. The venom can cause significant pain, swelling, sweating, and nausea. In rare cases, the venom can cause more severe symptoms like muscle weakness, abdominal pain, and tremors. Antivenom is available and effective in treating serious bites.
Treatment: To prevent Redback infestations, keep outdoor areas clean and free of clutter where spiders can hide. Seal cracks and crevices in and around the house. Be cautious when reaching into dark, undisturbed areas. If a Redback spider is found, it's best to contact pest control professionals for safe removal and treatment.
Appearance: White-tailed spiders are easily identified by their cylindrical body shape and the distinct white or grey spot at the end of their abdomen. They are usually dark reddish-brown or grey.
Web: These spiders do not build webs for catching prey. They are nomadic and prefer to roam in search of food, often found under bark, rocks, leaf litter, and within houses.
Danger Level and Bite: The bite of a White-tailed spider can be painful but is usually not dangerous. It has been wrongly attributed to causing necrotic ulcers, but recent studies have dispelled this myth. Typical symptoms include temporary redness and itching.
Treatment: To discourage White-tailed spiders, reduce clutter and debris around the house where they might hide. Regular vacuuming and dusting can help remove any spiders and their prey from inside the home.
Appearance: Orb-Weaver spiders vary in colour and size, but they are generally known for their large, rounded abdomens and often bright, patterned bodies. They are most notable for their web-building skills.
Web: They create large, intricate, wheel-shaped webs, typically found in gardens and near outdoor lighting. These webs are used to capture flying insects.
Danger Level and Bite: Orb-Weavers are not considered dangerous to humans. Their bite is rare and typically only occurs if they are provoked. If bitten, the effects are usually minor, including mild pain and swelling.
Treatment: Orb-Weaver spiders are beneficial for controlling insect populations. If their presence is undesirable, gently removing the web with a stick or broom and relocating the spider can be effective.
Appearance: Black House spiders are medium-sized, with females reaching up to 18mm in body length. They have a dark brown or black velvety appearance.
Web: Their webs are messy and often found in corners, around windows and doors, under eaves, and in other sheltered areas. The web has a funnel-like structure where the spider hides.
Danger Level and Bite: While their bite can be painful, it is not generally dangerous. Symptoms may include local pain, nausea, and sweating.
Treatment: Keeping areas around the house clean and free of clutter can help prevent these spiders from settling in. Sealing cracks and crevices in walls and around windows can also help.
Appearance: Wolf spiders range in size, typically measuring between 1-3.5 cm in body length. They are usually brown or grey with a hairy body and strong markings.
Web: Wolf spiders do not build webs. They are ground dwellers that hunt for prey, sometimes living in burrows or under rocks and leaf litter.
Danger Level and Bite: They are not aggressive and will only bite if provoked. Bites can be painful but are not considered dangerous. Typical symptoms include redness and swelling at the bite site.
Treatment: To manage wolf spiders, maintain a clean and tidy garden, reducing shelter for these spiders and their prey. Inside the home, regular vacuuming and keeping areas clutter-free can help.
Signs you Have a Spider Problem
Identifying a spider infestation early can be key to managing it effectively. Here are some signs that might indicate a spider problem in your home or garden:
- Visible Spiders and Webs: The most obvious sign is the presence of spiders themselves or their webs. Check corners, under furniture, in basements, and other less-disturbed areas.
- Seasonal Increase: Spring often marks the breeding season for spiders. A few spiders seen during this time can quickly multiply, leading to a more noticeable infestation later.
- Prevalence of Insects: An abundance of insects can attract spiders seeking food. If you notice an increase in flying insects, spiders might follow.
- Specific Areas to Inspect:Â
-
- For redbacks, inspect roof voids, downlights, pool fencing, and outdoor items.
- Check door and window frames, vents, and eaves for black house spider webs.
Preventing a Spider Infestation
Preventing spiders from entering your home involves a two-fold approach: blocking their entry points and making your home less attractive to them.Â
Here are some effective strategies:
- Secure Entry Points:
- Ensure insect screens on windows and doors are intact and fit well. Repair any holes or tears immediately.
- Install weather strips under doors to close gaps where spiders can enter.
- Seal cracks and crevices in your home's foundation, walls, and around utility lines. Use caulk or a similar sealant for small openings.
- Make Your Home Less Attractive:Â
- Keep plants and vegetation well-trimmed and away from your home’s perimeter. This reduces hiding places for spiders and other pests.
- Maintain cleanliness both inside and outside your home. Regular vacuuming and dusting can remove spiders, webs, and egg sacs.
- Reduce clutter, particularly in garages, attics, and basements, which can provide ideal habitats for spiders.
- Turn off outdoor lights at night or use yellow bulbs, which are less attractive to the insects that spiders feed on. Position lights to shine away from the house, drawing insects and spiders away from your living spaces.
- Regular Inspection and Maintenance:
- Conduct regular inspections of dark and less frequented areas in your home where spiders may hide.
- Clean up garden debris, stacks of wood, and leaf litter around your property, as these can be attractive to spiders.
- Control Other Insects:
- Reduce the presence of other insects, which are food sources for spiders. This can be achieved through good housekeeping practices and, if necessary, the use of appropriate insecticides.
By implementing these measures, you can significantly reduce the likelihood of spiders entering and settling in your home, creating a more comfortable and pest-free environment.
Spider Bite First-Aid
If you or someone else is bitten by a spider, the following steps can help mitigate the effects:
- Remain Calm: Keep the victim calm and seated to prevent the spread of venom.
- Clean the Bite: Use water and disinfectant to clean the area. Apply ice if it is painful.
- Seek Medical Attention: If the spider is a redback or cannot be identified, or if there is concern for the victim's health, seek medical help.
- Funnel-Web Spider Bites: These require immediate medical attention. Keep the victim still, immobilise the limb, apply a pressure bandage, and call for emergency assistance.
Taking a photo of the spider can be helpful for identification purposes.
Additional Spider Information
Understanding the distinction between web-building and hunting spiders is essential for effective spider management. Web-building spiders, such as the Redback and Black House Spider, create webs to capture prey. These webs are often visible, making it easier to locate and treat these spiders. Regular removal of webs, along with the application of insecticides to known webbing areas, can effectively control their populations.
Hunting spiders, like the Huntsman and Wolf Spider, do not rely on webs for capturing prey. They are more mobile and require a different approach. These spiders are best managed by reducing their food source and shelter. Ensuring your property is free from insects and clutter can make it less attractive to these spiders. Perimeter treatments with insecticides can also be effective in deterring them from entering your home.
A comprehensive pest treatment is crucial in spider management. This involves not only addressing the spiders themselves but also controlling their food sources (other insects) and making the environment less hospitable for them. Regular inspections and treatments by professionals like Coastwide Pest Control can help maintain a spider-free home.
