Melbourne homes are often inundated with several spider species during spring and summer.
The hot and humid conditions can lead to a spike in the populations of the insects they eat. Likewise, many spiders come out of hiding in search of a mate.
Most of the common spider species found in Melbourne are reluctant to bite and rarely cause significant injuries.
However, becoming familiar with their key characteristics can reduce your risk of envenomation and a potentially adverse reaction.
In this article, we cover the appearance, habitat, and danger level of six of the most common spider species found in and around Melbourne homes.

Where Will I Find Spiders?
Most spiders are nocturnal and are most active overnight hunting their prey. During the day, they hide within their webs or burrows. Spiders will hide out in dense vegetation and grass. Shrubs, bushes, and trees are all home to spiders. They also like to hide around docks, under decks, behind shutters and siding, or in doorways or under roof eaves.
Spiders that find their way into homes, sheds, garages, or other outbuildings and often get inside through:
-
Open windows or doors
-
Vents
-
Spaces in exterior walls, the foundation, or roofline
Once inside, they will seek out dark, quiet areas to hide and hunt for insects. Spiders live in closets, boxes, under furniture, in the corners of rooms, and on windowsills. They are also regular visitors to attics and crawlspaces.
