When you call The Pest Investigators on 1300 839 916 for your local spider control, you get what's important. For good Spider Control, it's getting the treatment into, up, around and through everywhere required to not only kill adult spiders: but the spiderlings, any active egg sacks, and treatment of webbing. You should be ok to clean any walls etc at least two weeks after the Spider treatment has taken place, by then the spiders will have ingested the product as they clean their webs.
Currently, there is no specialist product on the market that can create a residual treated zone for a hunting spider control. Any hunting spider treatment, must be thorough, as well as fairly specific in its approach - due to the necessary requirement of direct application which should almost always be coupled with good maintenance practices, such as removing excessive leaf litter or general debris. In a few cases, it has even been beneficial to open up an area of the building (if possible) to allow light to pass through. Many hunting spiders can't stand light and are night crawlers.
The Sydney funnel - web Atrax robustus is considered Australia's most deadly spider, possibly the world. Here in Queensland you may encounter the northern funnel web Hadronyche formidabilis however sightings are rare unless a bite has occurred - even then, a death from the Sydney Funnel has not been recorded since the antivenom was made available in 1981.
During the night, particularly if you live on acreage or a large block, go ahead and shine your torch (you'll need a fairly powerful one) and see if you can see any tiny shiny lights on the ground. There's a fair chance they are a trapdoor spider, waiting for it's next prey to come it's way.
As for White - Tail Spiders Lampona cylindrata and Lampona murina, (they are a hunting spider) This article from the Australian Geographic talks about facts on white - tailed spiders. As has been widely thought, they in cannot cause “necrotic arachnidism” - the condition of flesh eaten or "rotten" by spider activity. According to this article, a white - tailed spider bite reportedly feels like a bee sting, with 27% out of 130 people in the study reporting severe pain, they also prefer to eat other spiders, like redbacks.

Redback spiders (Latrodectus hasseltii) prefer drier areas, and are extremely venomous, second only to the funnel-web. In regional Australia, where it tends to be a little drier than coastal areas - caution should always be taken when gardening, or when working in an area that's been left undisturbed for some time. Like most pests, redback spiders prefer darker areas, their webs are easily distinguished by there uneven, criss cross type structure and their egg sacks look much like cream coloured peas.
Of the two spiders that are the most hazardous to humans - one being the redback - the other being the funnelweb - we usually come across the redback spider in the South Burnett, Toowoomba or Somerset regions on most spider encounters. Contact The Pest Investigators for a redback spider treatment that is thorough. We'll get into any weep holes, underneath outdoor seating or children's play equipment wherever they are.
We recommend leaving the spider webs in place until 2 weeks after the treatment. Please do not clean or remove spider webs from walls prior. it is important for any webbing to remain during the process. By removing the webbing material it's likely to cause the treatment to be less successful, because spiders return to their webs at night to clean and prepare them, all ready for their next catch - and ingesting our products at the same time.
