|Sydney Funnel-Web spiders: aggressive by nature - can be deadly|
Area of distribution: The Sydney Funnel-Web Spider is a ground dweller, commonly found in moist soil areas along much of the eastern coastal area of New South Wales and Victoria.
Venom toxicity: - The Sydney Funnel-Web Spider is one of the world's most deadly spiders. Both the male and female carry atraxotoxin, one of the world's most dangerous toxins.
DANGER TIME: The mature male Sydney funnel-web spider will leave it's burrow and wander off during hot humid nights, looking for a mate. At this time it is known to enter homes, lodge in footwear, clothing and swimming pools, where they can survive several days under water.
Highly aggressive: The male Sydney funnel web spider is highly aggressive when disturbed or cornered and is able to inflict multiple bites, with its "flick-knife" hardened fangs.
Heavy rain or earthworks will drive the Sydney funnel-web spider out of it's burrow and are commonly found wandering around the garden or in the home at such times.
An anti-venom is available in most major hospitals and ambulance vehicles in "funnel-web country". If bitten, you should apply first aid and medical attention (ambulance) should be sought as soon as possible.
Spider identification: -The male Sydney funnel-web spider is about 25 mm and the female about 30 mm in body length. They are shiny black in colour with a dark purplish brown abdomen with a covering of reddish hairs.
Unique identification markings include it's long spinnerets, that is, the two appendages on the end of the abdomen. Also the male Sydney funnel-web spider has a distinctive spur on both it's second front legs - refer to illustration on left.
The Blue Mountains funnel-web spider is highly venomous and is found in the Blue Mountains area, as far west as the Bathurst - Orange region and occasionally in the Sydney basin.

|Red-Back spiders - highly venomous - can be deadly|
Area of distribution: Australia-wide.
Venom toxicity: The Red-Back spider can inflict a painful bite which can be fatal, especially to the young and elderly. An effective anti-venom was developed in 1956. About 250 people receive the anti-venom each year.
Nerve poison: Only a small amount of venom can cause serious illness, as the poison attacks the nervous system. Systemic envenomisation usually results in headache, nausea, vomiting, abdominal pain, pyrexia, hypertension and in severe cases, paralysis.
Excruciating pain: The pain around the spider bite area can be excruciating. If bitten, immediately apply first aid and seek medical attention (ambulance) should be sought as soon as possible.
Spider Identification: -The red-back spider size varies greatly. The male can be tiny, with the abdomen of the female growing to the size of a large pea. Red-back spiders do NOT always have a "red" marking.

|White-tail spiders: venomous and highly dangerous ?|
Area of distribution: Australia-wide.
Venom toxicity: The bite of a white-tail spider may cause nausea and burning pain followed by swelling and itchiness around the site of the bite. In some rare but dramatic cases, a severe allergic reaction, blistering or ulceration of the skin, similar to gangrene, has apparently been caused by a white-tail spider bite.
Proven dangerous? Some scientific researchers are unconvinced as to whether this spider causes such horrific ulcerations. Bacterial infection of the wound caused by Mycobacterium ulcerans carried on the fangs of the white-tail spider, may be a contributory factor.
In any case first aid and medical attention should be sought, if bitten, as and when any adverse health effects are observed.
Spider identification: The adult white-tail spider adult varies in size from 12 to 20 mm in body length; is grey to black in colour with a white section on the end of it's tail - as illustrated.

|The cost for Professional Pest Control for spiders|
|Consumer Protection Advice - Pesticide Safety Issues|
safety be wary of very cheap prices for spider control
- check which pesticides are to be used - do they propose to
use the far cheaper, less effective, solvent based pesticides which
can be acutely harmful in premises where occupants may suffer
from asthmatic or other bronchial ailments.
Be careful when selecting a pest controller it's far too easy to get a State Govt WorkCover issued Pest Control Licence and start up a pest control business - using mostly unsupervised trainees who have little knowledge of spider pest species or spider control pesticides .... more details
