How to identify a Golden Orb Weaving Spider
Golden Orb Weaving Spiders are large spiders with silvery-grey to plum coloured bodies and brown-black, often yellow banded legs. The males are tiny and red-brown to brown in colour. The main difference between the common Sydney species, Nephila plumipes and N. edulis (which is commoner in inland regions) is the presence of a 'knob' on the front of the sternum (the heart shaped plate on the underside of the body between the legs) of N. plumipes.
Where are Golden Orb Weaving Spider commonly found?
Golden Orb Weaving Spiders are found in dry open forest and woodlands, coastal sand dune shrubland and mangrove habitats.
All orb weaving spiders make suspended, sticky, wheel-shaped orb webs. Webs are placed in openings between trees and shrubs where insects are likely to fly.
Why are Golden Orb Weaving Spider considered a pest?
Orb weavers are reluctant to bite. Symptoms are usually negligible or mild local pain, numbness and swelling. Occasionally nausea and dizziness can occur after a bite.
What is the biology and lifecycle of a Golden Orb Weaving spider?
In the Golden Orb Weaving Spider group, it is common for a number of tiny (6 mm) males to live around the edges of a female's web, waiting for a mating opportunity. After mating, the female Golden Orb Weaving Spider wraps her single egg sac in a mass of golden silk, which is then hidden on foliage away from the web, disguised within a curled leaf or sprig of twigs.
Management Tips for Golden Orb Weaving Spider
General Spider Prevention Tips
Keeping garden beds and rubbish away from the edge of the house will significantly reduce the spider population.
If garden beds next to the house are kept in place, it is important to keeping vegetation trimmed back from the edge of the house and paths.
Make sure insect screens and draft excluders are in good repair and well fitting
Keep clothes and shoes off the floor to reduce spider hiding places.
General Spider Control Tips
The best treatment for web-building spiders is to spray their webs and hiding places with an insecticide (ready to use pump back or aerosol). The key tip to get the best performance is to wait a day or two after spraying before brushing down any webs. This ensures the spiders will have picked up a lethal does of insecticide (by walking on the web) and by using a brush (rather than hose), you can ensure the insecticide remains in place to prevent new spiders taking up residence.
To prevent web-building spiders take up residence in the first place, spraying around doors, windows and vents, as well as under eaves and guttering delivers excellent results. As these spots tend to be sheltered from sun and rain, the treatment can last many months.
It is a lot more difficult to prevent running spiders entering the home. Carrying out a preventative spray around the perimeter of the home and any openings will have some benefit, although running spiders often walk on the tips of their legs, preventing them from picking up a lethal dose of insecticide. However, if you carry out a preventative treatment for web-building spiders and other insects, the numbers of running spiders will be greatly reduced, as there will be little prey for them to feed on.
Even with the best control program the occasional spider may get in. A crawling insect aerosol should be kept on hand to spray the occasional unwanted spider. Ensure the spider receives a good dose and keep your distance.
