Below we have provided some information on some commonly encounted spiders in Perth.
Black House Spider
Black house spiders are a dark brown to black spider. The female is usually about 15mm to 18mm in body length but can get even larger. Black house spiders are commonly found around window and door frames, and especially around pergolas and patios. They make a messy web, usually with a distinctive round entry, not unlike a funnel shape. The black house spider may bite if provoked. Black house spiders are venomous, but are not considered dangerous. They seldom bite unless provoked. The bite may be very painful and cause local swelling, and in some cases cause vomiting and nausea.
The female redback is usually 12-15mm in body length with a smooth black body with a flash of red or orange on its abdomen. The redback can give a painful bite, causing illness and if medical assistance is not sought can cause death. Redbacks can be found in stacked items, leaf matter, sheds, and other quiet dark places. Redbacks make an untidy web and will be more likely to bite when she is guarding her egg sacs which can contain up to 2 000 babies.
White Tailed Spider
The whitetailed spider is generally a dark grey to black spider with a cigar shaped body finishing with a characteristic white spot on the end of its abdomen.
It is commonly found outdoors around mulch and leaf matter, behind the bark on trees and under rocks.
Upon wandering indoors it can be found under couches, fridges and particularly bathrooms.
Although the whitetailed spider is not particularly aggressive, it will administer a painful bite if touched or placed against the body such as within clothing or a towel and bedding . White tail spider bites represent a high portion of all spider bites to people in Perth due to their wandering habits. The bites can be very painful, and may cause nausea, malaise and headaches.
Orb Weaver Spider
Orb weavers are probably best known for the large sticky webs they make over night. Orb weavers can get to large sizes, especially when well fed. Despite their fearsome appearance, Orb weavers cause minimal risk to humans as they seldom bite, and only cause mild pain if they do so. Orb weavers are often beneficial in the garden as they are great predators of many nuisance flying insects. Their large sticky webs are normally found around trees, or light sources, where flying insects are likely to be trapped. There are great variances of colour and appearance of spiders in the Orb weaver family.
