Spider pest control prices & warranty
All our general pest control treatments include spiders. Most people choose the Complete Pest Package for $250 which includes…
- Treatment of any size house, inside and out for $250
- Cockroaches (excludes Germans), Spiders, Ants (internal only) and Silverfish
- Full 12 months warranty even on spiders and ants (no-one else does this)
Spider pest control treatments are only warranted for webbing spiders which includes redbacks attached to the house or other physical structures.
We cannot provide warranty on spiders on shrubs or bushes because plants lose their leaves (or grow new ones) and any chemical applied will either disappear (old leaves) or not be there in the first place (new leaves).
Where can I take a funnel-web spider for collection?
The Australian Reptile Park accepts male and female funnel-webs for its venom-milking program. They collect the venom for serum laboratories to make antivenom. They also accept all native spider species for education purposes.
There are several drop-off points in Sydney, Newcastle and the Central Coast.
Dangerous spiders in Newcastle, Australia
Sydney Funnel Web Spider
Sydney Funnel Web
With highly toxic venom produced in large amounts and large fangs to inject it, the Sydney funnel-web is without a doubt the deadliest spider in Australia, and possibly the world.
Found in most parts of Newcastle, they burrow in humid sheltered places. They can wander in backyards and sometimes fall into swimming pools, and though they’re not often encountered, they can be quite aggressive when threatened.
Though just 1.5-3.5cm big, the Sydney Funnel-web has fangs larger than a brown snake’s and so powerful they can even pierce through nails and toenails.
The Sydney Funnel Web spider has a compound that can attack the human nervous system and alter the functioning of all organs and, when coming from a male, can kill. One in six bites causes a severe reaction, but since the antivenom has been made available, in 1981, no fatalities have been recorded.
Redback spiders are found throughout Newcastle. They often hide in dry, sheltered places such as garden sheds, mailboxes and the classic place, under toilet seats.
We find that recent construction in the area has a direct impact on Redback spider numbers. Our theory is redback spider eggs are often transported attached to wooden pallets and then distribute from there.
Numbers of redback spider bites are uncertain, but about 2000 are reported each year and about 250 people receive antivenom. No deaths have been recorded since redback antivenom became available in the 1950s.
Most serious bites are from the female redback spider, which measures about 1cm long (bigger than males) and is recognisable by the well-known red stripe on its back, from which it gains its name. Their venom affects the nervous system, which is potentially dangerous for humans, but their small fangs make many of the bites ineffective. The main symptom is severe and persistent pain – which can last hours to days depending on the person’s sensitivity to the venom – and may include nausea and lethargy.
There are a few species of mouse spider found across Newcastle and they’re typically found in burrows, often near rivers or waterways, and can occasionally be found in suburban areas.
Their venom is similar to the funnel-web spiders, although no deaths have been attributed to them. Studies have shown the funnel-web spider antivenom to be effective for mouse spider bites; and because it is sometimes difficult to tell the two species apart, the bites should be treated with the same precaution.
Mouse spiders are rather lethargic and rarely aggressive. The females generally remain in their burrow, while the males wander looking for them, generally in late summer to early winter. Unlike other spiders, mouse spiders are often active during the daytime, while other species from the same family prefer to wonder at night to avoid the heat and the day-active predators.
Trap Door Spiders
These spiders are named after their habit of camouflaging the entrance of their burrow to trick their prey into falling inside. They measure about 1.5 to 3cm long and as is often the case, females are distinctively larger than males but males tend to be more aggressive when feeling threatened.
Found throughout Newcastle’s natural or urban environments, trap door spiders cause only minor symptoms for humans, generally inflicting only localised pain, but sometimes nausea, lethargy and malaise.
Just like the mouse spiders, trap door spiders are often mistaken for funnel-web spiders, especially since the early effects of their bites are similar; these spiders should therefore be treated with caution. While most spiders live for about one year, trap door spiders can live between five and 20 years.
White Tailed Spiders | White Tip Spiders
Found in natural and urban areas across Newcastle. Unlike burrowing spiders, white-tailed spiders are mobile hunters and wander about at night, hunting other spiders.
Though white-tailed spiders have a reputation for releasing necrotising (flesh-eating) venom, the scientific evidence doesn’t support this. More likely, the spiders were wrongly held to blame for difficult to diagnose skin ulcers. Recent studies have shown the venom causes no major danger to humans and is limited to mild local pain.
Huntsman spiders are widespread in Newcastle. They are famous for their up to 15cm leg-span. In reality, they are reluctant to bite and more likely to run away when approached and their venom isn’t considered dangerous for humans.
Despite their intimidating size, huntsman spiders can be an ally in the house; they help with pest-control by eating smaller insects.
Common garden orb weaver spider
Garden Orb Weaver Spider
Garden orb weave spiders are aggressive: they’re the most common spider species to bite.
They measure between 1.5cm and 3cm and live in all the gardens, generally weaving webs between trees, on hedges or washing lines, in places where other insects are likely to fly and get caught in the sticky threads. Active at night, they hide during the day and rest with their legs withdrawn under the body, hanging off a thread under a leaf or in the clothes hanging from the line.
How does Newcastle Pest Control treat for spiders?
Webbing Spider Treatments
Not all spiders treatments are the same. The most common spider treatment is for webbing spiders.
Effective treatment requires specialised application equipment. We dust all voids and cavities in walls, eaves, framing etc. eliminating the spider’s refuge.
Spiders establish themselves close to an escape area into a void. For effective control, you must treat the voids directly. The most important formulation in spider control is a pest control dust. You can’t rely on the residual nature of a spray because there’s no guarantee spiders will make contact with the active.
For treating external webbing spiders such as Redbacks invert all outdoor furniture to expose the underside where spiders hide during the day.
We will also inspect and treat hollows in retaining walls or other garden sculptures.
The Importance of residual treatments for spiders
Webbing spiders move by a process known as ballooning. Young spiders secrete a silk strand into the air on a prevailing breeze and are picked up and carried by the wind until they hit a solid surface. With a residual chemical in place, these spiderlings are killed preventing or suppressing recolonisation while the residual lasts.
Non Webbing Spider Treatments
Non-webbing spiders have completely different habits and are very difficult to control. A lack of webbing makes them tricky to locate. Typical pests from this group include the Huntsman spider & Wolf spider. These spiders hunt for prey (usually small insects) in cracks and voids or across open ground.
Dusting is essential for treating voids while an internal fine pest spray pushes spiders out of their harbourages. Huntsmen love to rest around curtains and above the rails.
External residual treatments are an important element of your control program but there are limitations. Wolf Spiders nest in soil burrows so we include a ground spray to about 5m out from the structure. Cavities are found in debris, mulch, retaining walls, paving, pot-plants, and rockeries – any area where stacked items create insect harbourage.
Treating dangerous species
Funnel web spiders are difficult to locate without very careful inspection of garden areas. These ground dwelling spiders rarely come in to contact with humans, only when digging into the ground. Unfortunately, the male spiders can roam during the mating season and wander into areas where they are a danger.
