Female red-headed mouse spiders are dark brown to black, and the jaws are sometimes red-tinged. The eastern mouse spider’s males are black with a bluish white patch on the front of the abdomen. Black house spiders, Badumna insignis, are also called window spiders because of the tendency to build their webs around window frames. These untidy, zigzag threaded webs usually have one or two funnel-shaped entrances leading into a tubular retreat, and some people mistakenly think they may be funnel-web spiders. These robust, hairy spiders range from 9mm to 18mm in length, are grey to black in colour, and are found Australia wide.
- Although the white-tailed spider likes to live in leaf litter and under logs, they often enter human houses.
- Legs are crablike and covered in fairly prominent spines.
- Creates a series of silken trip lines from the entrance to the burrow to warn of potential prey and any danger.
- However, they’re also incredibly resilient and can live up to one year without feeding on anything.
- This rhetoric greatly exaggerates the relative risk of Australian spiders, leading to excessive pesticide use and unnecessary phobias.
Those at greatest risk from a spider bite are the very young or elderly, and those with pre-existing cardiovascular disease. The best spider control methods are to stop them from entering houses, and using protective clothing and gloves while gardening and doing similar activities. The only spider in Victoria to have caused any human deaths is the redback spider.

How To Get Rid Of Spiders In And Around Your Home
The lifespan of the garden orb-weaver is approximately twelve months. It is a widespread species having been recorded from all states except Tasmania. Most serious bites are from the female redback spider, which measures about 1cm long and is recognisable by the well-known red stripe on its back, from which it gains its name. Their venom affects the nervous system, which is potentially dangerous for humans, but their small fangs make many of the bites ineffective.
A bite is very rare, but it can be excruciatingly painful, causing nausea, sweating and swelling. Black house spiders are typically found around eaves, under external window sills and in wall cavities. They build a tunnel-shaped web and can bite if disturbed.

This includes the Hornsby Plateau to the north, the foothills of the Blue Mountains to the west, and the Woronora Plateau to the south. On hatching, the little spiders scatter to find their first meal. Two of the commonest Australian species are Lycosa godeffroyi and Lycosa leuckartii.
If they’re close enough to your house outside they may make their way inside soon enough. Keeping a clean buffer zone around the outside of your home will help to keep spiders at a distance. Some people prefer to remove nests to reduce the risk of stings.
Educate children that non aggressive spiders will not go out of their way to bite, but all have a venom to catch prey, and should be treated with care. Most spiders we find in our homes are harmless and are actually great for keeping your home free from other insects. Regardless, no one likes a spider hanging around the house – pun intended. White tip spiders are a reddish-grey in colour, with a whitish tip at the base of the abdomen.
Australian Spiders: The 10 Most Dangerous
Spiders play an important part in our environment, because they are essential to natural ecosystems. Some spider populations are threatened because of habitat destruction, but many spiders have adapted to live alongside humans in houses, sheds and gardens. Spiders usually feed on insects, making them quite beneficial to humans. These spiders are considered harmless to humans and bites are extremely rare.
Scorpions can deliver a sting that results in severe burning pain for several hours. The Sydney funnel-web’s fangs are bigger than a brown snake’s, though the spider is only from 1.5- to 3.5cm, however, the bite can pierce a person’s toenails. Victoria has one species of funnel-web, but a bite isn’t known to be deadly. Spiders belong to the class Arachnida, with other members including scorpions, ticks and mites.

These “household spiders” don’t build up to the numbers in the natural environment that we see around our house. Therefore spider control is about returning spider numbers back to normal levels. The female constructs several white silk egg sacs, which are secured within the web retreat.
Their webs are somewhat funnel-like in appearance, but don’t mistake them for funnel spiders—black house spiders don’t burrow in the ground or disguise their webs with debris. Black house spiders are widely distributed in southern and eastern Australia. These spiders are naturally found in the bark of trees, but are common to urban areas and are often called window spiders. Their webs form untidy, lacy silk sheets with a funnel in which the spider sits. The female constructs several white egg sacs, which are secured within the web. White-tailed spiders are hunters rather than spinning a web to capture prey.

You should keep these away from pets and/or children, because they stick to whatever steps on them. However, application of vegetable oil to anything that happens to inadvertently gets stuck quickly releases them. I have used these for years, and they really are an excellent product. They are easily disposed of when the bug “boot hill” needs to be changed with a new one. Simply fold in half, sticky side to sticky side, and toss them in the trash. Sometimes, you might have a pest problem that is difficult to manage yourself.
Spiders can be a major cause for concern as venomous bites may cause injury, serious bodily harm and even death. Some people are severely allergic to spider bites and may go into anaphylactic shock, which can be lethal. In Australia, deadly spiders include the Redback Spider and Funnel-Web Spider, however since the introduction of anti-venom, there have been no recorded deaths. Other spiders of concern include the White-tailed Spider, Mouse Spider, Black House Spider and Garden Orb Weaver Spider.

Trapdoor spiders, mouse spiders and black house spiders are commonly mistaken for funnelwebs. These sure-footed and agile spiders are nocturnal and sometimes seen indoors at night, hunting for insects. They have keen eyesight and are good hunters, running down and pouncing on their prey.
These are perhaps the most venomous spiders in this country. There are also species of deadly tree funnel-web spiders, but luckily not in Geelong. Since they have got a bigger appetite, wolf spiders are often found wandering on the ground, especially at night. This is a non-aggressive spider and runs very fast when disturbed. Their bite is painful and can cause itchiness, nausea, dizziness and rapid pulse. When venom is injected into your body through the bite, you will experience nausea, fever, muscle spasms, or cramps.
If you come face to face with an unwanted spider in your house, we recommend using a container and piece of paper for a simple catch-and-release into the garden. If the webs are what bothers you — and we’ve all walked face-first through a web at some point — sweeping them away will usually be enough for the spider to move on. This rhetoric greatly exaggerates the relative risk of Australian spiders, leading to excessive pesticide use and unnecessary phobias.

The trapdoor spider lives in a burrow, which may have a “trapdoor” camouflaging its entrance . Unlike funnel-web burrows, there are no silk trip lines around the burrow. A bite from a trapdoor spider doesn’t usually require emergency medical treatment.
Storage stacks and disused furniture will encourage the breeding of this spider. In nature, it occurs under logs, bark, sides of rocks, etc. [newline]As the spider rarely leaves its web, humans are not likely to be bitten unless some part of the body (eg. the hand) is put into the web. Always check before moving items that have been stored outdoors for some time.
When treating, invert all outdoor furniture to expose the underside where spiders hide during the day. Spiders establish themselves close to an escape area into a void. For effective control, you must treat the voids directly.
Huntsman spiders are known by this name because of their speed and mode of hunting, they can also move sideways. They are not aggressive, but if provoked their bite can be painful but not poisonous. They normally live under the bark of trees during the daytime and emerge at night.
