Most homes are visited by spiders who have a very important role in the garden to help control pests of plants or other pests that may inflict havoc on your garden. Spiders should be regarded with respect.

However due to the fact that a lot of Australian spiders are highly toxic and can be aggressive it is important to ensure that you provide a safe environment for your family and pets.

Spiders Features

Spiders are mostly nocturnal leaving their burrows and nests in search for food at night. Webs of the web-spinning variety are made at night to catch their prey. Prey usually consists of small arthropods however cannibalism does occur usually after mating in which the female will then eat the fluids of the male.

While the venom of some spiders is fatal to humans, a lot of spider bites only cause mild irritation and swelling so it is vital that when bitten by a spider that identification is obtained.

Ground Dwelling Spiders

Ground-dwelling spiders make their homes by digging holes in the ground and live in their burrows with silken web materials. Some of these spiders are regarded as Toxic and in some areas are very Toxic.

Some common examples of ground dwelling spiders include:

Trapdoor Spider: These spiders have very strong jaws and sharp fangs. They are a stocky looking spider with thick, short legs measuring around 2.5 cm long but have been found bigger. Trapdoor spiders are brown to dark brown, heavily covered with dark hairs. Their bite is considered non-toxic but may produce some pain.

Mouse Spider: These spiders can be black or brown in colour and have short, stocky legs. The shell of these spiders is quite glossy with a high broad head and usually measure around 1-3 cm in length. The females are much bigger than the males. Males have a bluish bottom with a red head. Their bite is painful and also toxic.

Wolf Spider: These Spiders range from 1.5 cm to 5 cm and are hairy with orangish-brown to grey and black with blemishes or stripes to help it blend into its surrounding. Just like a wolf they like to chase and jump onto their prey. The bite of a Wolf Spider is painful and are toxic.

Huntsman spider: These spiders are large spiders with long legs. They are brown with flat bodies that are around 1.5 to 2cm with a leg span of up to 15cm. They are usually found in narrow spaces under back or in rock cervices. Huntsman bites are very rare and they are not toxic to humans.

Control

To help control the spiders in your household it is best to identify all spiders found and kill those that are regarded as toxic to humans.

Always take care when using pesticides in the garden as sometimes you can force the spiders into the house when they try to avoid the areas treated and for this reason it is best to have a licenced pest controller treat your home for spiders. Wet weather can also force ground dwelling spiders into the house or in swimming pools. Never remove the spiders in pools by hand as some will live on the bottom breathing through air trapped in their hair.

Always inspect footwear and clothing that has been left outside to make sure no spiders have taken shelter within. This includes toys or other articles that have been left outside.
