Red backs usually make their homes in sheltered, out-of-the-way areas, and are usually not dangerous unless provoked. Only the female red back bites. Red back spiders can be dealt with using topical sprays, and by regularly checking sheltered areas for evidence of red back webs.

Red back spider habitats.

Red back spiders are found all around Australia, including in Sydney, with sightings common in dry areas and urban or built-up environments. This is because red backs make their home in protected, out-of-the-way areas such as in outdoor furniture and equipment, or in rarely used machinery or materials.

Red back spiders live in messy, loosely-spun webs with leaves and rubbish caught in them, that are typically situated close to the ground. The spider is usually found sheltering in a funnel-shaped hiding space in one corner of the web, and typically only emerges when provoked or when defending her eggs, which are white and fuzzy in appearance.

Red back bites.

Although the red back spider is shy and timid and not prone to aggressiveness, they are highly venomous. A bite from a red back can potentially be fatal, particularly for the very young or for the elderly.

Red back bites induce a variety of symptoms in victims, with common symptoms including nausea and vomiting, pain and muscle spasms, fever and sweating, and restlessness. Fortunately highly effective anti-venom is available for red back spider bites, allowing for prompt treatment. Initial treatment, however, should involve icing the bite and if appropriate, the use of mild painkillers to help manage any pain or irritation.

Managing red backs.

Red back spiders can be managed using care and caution when working in the garden or in or around the sorts of sheltered areas where red backs make their homes, particularly when children are nearby. Wearing gloves is always recommended in case a nesting red back is inadvertently disturbed.

If a red back infestation is a concern, then calling in an experience Micropest pest controller to help identify and manage the infestation is recommended. As pest control treatments tend to only have a temporary effect on managing red back spider numbers, ongoing treatments are needed to ensure that red back numbers remain in check.
