Sigillate Trapdoor Spider Brown Trapdoor Spider Nest Brown Trapdoor Spider Male Brown Trapdoor Spider Female
 

Brown trapdoor spiders are often mistaken for Funnel Web spiders but their bites are not dangerous - local pain and swelling may occur. The same goes for the Sigillate Trapdoor Spider, although there is one report of unspecified "severe effects".
Seek medical attention if symptoms persist.

 

 

Eastern Mouse Spider Male

Eastern Mouse Spider Female

 

Mouse spider venom may be very toxic, but only one serious envenomation has been recorded, other bites causing minor effects. Funnel Web spider antivenom may be effective.
Until more toxicity data is available it is prudent to treat as for funnel web spider bites, especially if the victim is a child.  Where possible, collect the spider for positive identification.

 

 

Sydney Funnel Web Blue Mountains Funnel Web
 

The bite is dangerous and can cause serious illness or death. The  male venom is more toxic than the female and initial symptoms include local pain, mouth numbness, vomiting, abdominal pain, sweating and salivation. There is an anti-venom available.
Bites are usually on a limb. Immediate action should be taken to apply a pressure bandage and immobilise the bitten limb by splinting.  Restrict the movement of the victim. If possible, capture the spider for positive identification.

 

 

Garden Wolf Spider Grey Wolf Spider
 

Bites are usually minor with local pain or itchiness.  Less commonly, symptoms can include swelling, prolonged pain, dizziness, rapid pulse and nausea. Seek medical attention if symptoms persist

 

 

Redback Spider
 

Redback bites occur frequently.  They can cause serious illness and have caused deaths.  Because of their small jaws, many bites are ineffective.  Common early symptoms are pain, sweating (always including local sweating at the bite site), muscular weakness, nausea and vomiting.  An antivenom is available - no deaths have occurred since its introduction.
Apply an ice pack to the bitten area to relieve the pain.  Do not apply a pressure bandage (venom movement is slow and pressure worsens pain).  If possible, collect the spider for positive identification.  Seek medical attention.

White-Tail Spider White-Tail Spider
 
Symptoms are usually confined to local mind stinging or burning pain, sometimes followed by development of an itchy lump.  Less commonly, bites result in swelling, discolouration and local ulceration, sometimes with nausea and vomiting.  There is no conclusive evidence that these spiders regularly cause significant skin damage or ulceration.
An ice pack may relieve local pain.  Seek medical attention if symptoms persist.
