Types of Spiders 

Treatment and control of spiders purely depend on the type of spiders situated on your property. Our fully licensed and qualified technician will be able to asses what problem you have a fit the treatment accordingly. 

Black House Spiders

The Common House spider or Black House spider is generally black to grey. A lot of spiders found around a property or inside houses are either this spider or from this family of spiders. They are commonly found around windows, fences, pergolas, eaves and other areas that provide shelter, food and security. The web of this spider is tunnel-like, it is usually obvious, roughly round and an entry hole. The female spider never leaves its nest unless she is forced. The female stays with the sac (eggs) and guards it. They generally feed on insects, usually ones that are attracted to light because they fall in their webs. The Common House spider or Black House spider has a nasty bite but not a deadly one. They are usually very timid, and most bite occurs when people attempt to move the nest or disturb them. Their bites are very painful and can cause local swelling. Other symptoms may arise such as nausea, vomiting, sweating and giddiness.

Daddy-long-legs Spiders

This spider, as suggested by its name, has very long skinny legs with a body that is very small in comparison to its legs. They are cream to pale brown and can often be found in and around houses. They will often spin tangled webs in corners of rooms and other areas that are not often disturbed, like under tables. They feed in insects as well as other spiders including Redback Spiders. They manage to defeat the Redback through spitting silk at them from a distance. They then wrap them up and incapacitate them while keeping the Redbacks deadly fangs at bay using their skinny log legs. 
Many believe that the Daddy-long leg have the most toxic venom of all spiders. However, there is no scientific evidence to back this up. Their venom is not that potent even for insects. The Daddy-long leg trick is that their legs are so long and slender that it is just about impossible for the Redback to bite anyone of them. 

Huntsman Spiders

This spider is dark and has long legs in comparison with its body. It is a relatively flat and hairy spider that feeds mainly on insects. They are generally a grey to brown colour, with banded legs sometimes. Feeding of insects and other invertebrates, they prefer to live outdoors under loose bark on trees, crevices on rock walls and in logs, they will emerge at night to feed. They often enter houses and are generally will be found on walls and behind curtains. They are also notorious for finding their way into cars and being found hiding behind sun visors or running across the dashboard. They can move sideways very quickly and can grow up to between 40-45mm long. Their bite is not toxic but can leave a nasty wound. A female Huntsman can lay up to 200 eggs, and these spiderlings will live for about two years or more on average. 

Redback Spiders

Redback spiders are one of the most known and poisonous spiders. They create tangled webs that are funnel-like wherein upper retreat area vertical, sticky catching threads run to ground attachments. Female Redback spiders are black (occasionally brownish) and have a distinct orange to red longitudinal stripe/hourglass shape on the upper abdomen. While the male Redback can sometimes be less distinct, with a light brown body and white markings on the top side of the abdomen, and a pale hourglass marking on the underside. They tend to build their webs in dry and sheltered positions such as among rocks, inside logs, shrubs, sheds, or in toilets. They mainly feed on insects but are capable of capturing animals such as male trapdoor spiders, small lizards and crickets if they become trapped in the Redbacks web.  The female Redback bite can cause death or severe illness. More than 250 Redback bites receive antivenin each year. If bitten safely and carefully collect the spider for positive identification and seek medical attention.

White Tail Spiders

This spider is dark reddish to grey in colour with a cigar-shaped body and dark orange-brown banded legs. It's most distinguishing feature being the white marking on the tip of its abdomen. The White-tailed spider can be referred to as a "wandering" spider not keeping one specific place as their home. They are generally found under bark and rocks, in leaf litter, logs, roof voids, gardens and homes. Their primary food source is other spiders. They typically hunt at night and are known to catch daddy-long-legs spiders, Redback Spiders and Black House spiders. Generally, the White-tailed spider will be attracted to your home due to other spiders they are hunting. Their bites can cause an initial burning pain followed by swelling and itching at the bitten area. 

False black widow

With a very similar body shape to the Redback spider, it can be easily mistaken at a glance. But False Black Widow spiders (also known as the Cupboard Spider, Brown House Spider and Dark Comb-footed Spider) range from a brown or reddish plum to satiny black. Males are around 4mm in size, and females average around 10mm. They have slender and shiny legs with a large round/egg-shaped abdomen. You can find them under rocks, timbers and bark in the bush where prey is available. Within these areas, they build tangled-looking webs that have sticky lines. However, in an urban situation, we are finding them more commonly in dark, sheltered and undisturbed places such as in sheds and garages, old furniture, under garden benches and in upturned pots to name a few.
