About Black House Spiders

Black house spiders (Badumna insignis) are common species found in Australia. They are known for their distinctive black or dark brown colour and are typically found in webs near human habitations, hence their name.

They are a common species of spider that is often encountered in and around houses, sheds, and other structures. Black house spiders are typically dark brown or black in color, and they have a robust body shape with long, spindly legs. They construct messy, irregular webs in corners, crevices, and other sheltered areas.

They are not considered dangerous to humans, but their bite can lead to pain, redness, swelling, and itching.

Black house spiders are medium-sized spiders, with females having a body length of about 12-18 mm and males having a body length of 9-15 mm. Black or dark brown, these spiders have eight eyes arranged in two rows, with the two largest eyes in the centre and the smaller ones on the sides.

Black house spiders are commonly found in Australia, including in Perth and throughout Western Australia. They are known for building webs near human habitations, such as in garages, sheds, and corners of windows and doors. In addition, they are often attracted to areas with a high population of insects, which serve as their food source. Black house spiders are also found in other outdoor areas such as gardens, parks, and wooded areas.

Life Cycle

The life cycle of black house spiders involves several stages, including egg, spiderling, juvenile, and adult. The female black house spiders lay their eggs in a silken egg sac, which they attach to their webs or nearby objects. When the eggs hatch, the spiderlings emerge and begin to spin their webs.

They feed on small insects and other small invertebrates. As the spiderlings mature, they shed their skins several times and grow larger. Once the spider has reached adulthood, it is fully developed and begins to reproduce. Black house spiders live for several years, with females generally living longer than males.

Frequently Asked Questions

Are Black House Spiders Dangerous?

Black house spider bites are venomous but are not lethal to humans. In most cases, bites from these spiders cause mild symptoms such as pain, redness, swelling, and itching, which usually resolve on their own within a few days. However, some individuals may experience more severe symptoms like nausea, vomiting, and headache, which may require medical attention. Therefore, it is always recommended to seek medical attention if you experience symptoms after being bitten by a spider.

Will Black House Spiders Return to My Property After The Extermination?

Black house spiders may return to your property after extermination, as they are native to the area and are likely to be present in the surrounding environment. However, the frequency and number of spiders returning to your property will depend on several factors, such as the severity of the infestation, the measures you have taken to prevent their return, and the availability of food and shelter in the surrounding environment.

To minimise the chances of black house spiders returning to your property, it is essential to follow preventative measures such as sealing cracks and gaps, keeping the house clean, removing webs, using insecticides, and keeping outdoor lights off.

Do Black House Spiders Eat Insects?

Yes, black house spiders do eat insects. As predators, they feed on various insects, such as flies, moths, and other small insects, which they catch in their webs. Their webs serve as traps for their prey, and the spiders use their fangs and venom to subdue their prey and then consume them.
