🕷️ Redback spider
Latrodectus hasselti
High — medically significant
🕷️ White-tail spider
Lampona cylindrata / murina
Medium — painful but rarely serious
Identify
Female: black with a distinctive red or orange stripe on the upper abdomen. Small (1cm body). Male is much smaller and brown, rarely responsible for significant bites.
Identify
Dark grey to black with a distinctive white tip at the end of the abdomen. Slender body (1–2cm). Smooth, no webs, a wandering spider that hunts other spiders.
Where
Dry, sheltered spots: under outdoor furniture, behind letterboxes, inside garden gloves, in rockeries and log piles, along fence bases, inside outbuildings and sheds.
Where
Inside homes under beds, in clothing, in shoes left out, and in bedding. Often enters homes at night hunting other spiders.
Venom
Alpha-latrotoxin causing latrodectism, severe localised pain, sweating, nausea, muscle weakness. Antivenom available and effective.
Venom
Causes localised pain and redness. The flesh-eating effect historically attributed to white-tail bites is not supported by research, this is a medical myth.
Treatment
Professional residual spray to all harbourage zones, fence lines, and shelter spots. Do not handle a redback spider.
Treatment
Residual spray to internal skirting boards and under-furniture areas. Reducing prey species (other spiders) also reduces white-tail activity.
🕸️ Black house spider
Badumna insignis
Low–medium — minor bite risk
🦀 Huntsman spider
Heteropoda / Delena spp.
Low — nuisance, not danger
Identify
Dark charcoal to black, robust body (1–1.5cm). Builds messy funnel-shaped webs in window frames, wall crevices, and under eaves.
Identify
Large, flat, grey-brown with legs spread wide (up to 15cm across). No web, a free-roaming hunter that flattens against walls and ceilings.
Where
Webs in window frames, door frames, wall crevices, gutters, and eaves, very common in Melbourne homes and rarely causes alarm.
Where
Behind wall hangings and mirrors, inside cars, in tree bark, under roof eaves, and behind loose bark outdoors. Enters homes seasonally.
Venom
Bites can cause localised pain, nausea, and sweating but are not usually medically significant in healthy adults.
Venom
Can bite if provoked, causes localised pain and swelling, not medically significant. Huntsmans are not aggressive and will not attack unprovoked.
Treatment
Residual spray to web sites, window frames, eaves, and external wall crevices. Webs brushed down before treatment to encourage contact with treated surface.
Treatment
Residual spray to interior perimeter, roof void, and external eaves. Huntsmans are beneficial predators — treatment focuses on reducing indoor presence for comfort.
🪟 Window frames & door frames
The most common black house spider web site, residual spray applied inside and outside all frames, where spiders rebuild webs after treatment.
- Black house
- White-tail
🏚️ Eaves & roof overhangs
Protected from rain and close to exterior lights that attract insect prey, prime territory for multiple species.
- Black house
- Huntsman
🌿 Garden, rocks & log piles
Dry, sheltered garden features are the primary redback habitat, treatment targets fence bases, rockeries, pot plant undersides, and garden furniture legs.

- Black house
📪 Letterboxes & outdoor fittings
Letterboxes, power boxes, tap fittings, and any enclosed outdoor structure provide sheltered, dark harborage for redback spiders.

🏠 Subfloor & garage
Dark, undisturbed subfloor spaces and garages harbour redback and black house spiders, webs are often found under beams and along perimeter walls.

Standard treatment
Interior and exterior residual spray for a typical Melbourne home, eaves, window frames, garden perimeter, and interior skirting boards.
$220 – $320
Redback-focused treatment
Extensive external treatment targeting redback harbourage zones, garden, fence lines, outbuildings, letterboxes, and all sheltered outdoor structures.
From $150 / visit
Annual program
Scheduled annual retreatment to maintain residual barrier, recommended for all Melbourne homes, particularly those near parks or with established gardens.
Exterior first approach
We treat where spiders live, external eaves, garden, and fence lines, not just interior surfaces where they occasionally wander.
Web removal before spray
Brushing down webs before spraying forces rebuilding on treated surfaces, significantly improving contact and kill rate.
Written reports
Documentation of species observed, zones treated, products applied, and recommended retreat interval.
Species specific priority
We note and prioritise redback activity in high-risk zones, children's play areas, gardens, and outbuildings, and treat accordingly.
Service guarantee
If significant spider activity returns within the guarantee period, we return and retreat at no additional cost.
All Melbourne suburbs
Same day bookings available across greater Melbourne, redback activity peaks in late summer and autumn.
