Black House Spider

Natural Habitat

Diet & Feeding

Carnivorous; they eat a variety of insects, including flies, beetles, moths, and mosquitoes, which become trapped in their messy webs.

Behavior Patterns

They are nocturnal and construct characteristic messy, funnel-like webs. They rarely leave their web unless forced and are known to be quite shy, retreating into their funnel when disturbed.

Risks & Benefits

Benefits the ecosystem by controlling pest populations. While they are venomous and their bite can cause local pain, swelling, and nausea, they are generally not aggressive and bites are rare.
