Big House Spider UK

A big house spider in the UK is a large, non-venomous spider commonly found in British homes. Known scientifically as Eratigena atrica, these spiders are famous for their impressive size, with leg spans that can reach up to 10 centimetres. In simple terms, they are the UK’s largest domestic spider, easily identifiable by their long legs and brownish bodies with subtle banding.

Here’s why these spiders catch attention: despite their intimidating size, they are generally harmless and play a beneficial role in controlling household pests such as flies, mosquitoes, and other insects.

Types or Styles of Big House Spiders in the UK

While “big house spider” often refers to Eratigena atrica, there are a few variations and look-alikes in the UK:

1. Giant House Spider (Eratigena atrica) – The classic big house spider, dark brown with lighter markings on the body. Most commonly seen in lofts, garages, and corners of rooms.
2. Domestic House Spider (Tegenaria domestica) – Smaller than the giant house spider but often confused with it. Typically found in basements and behind furniture.
3. Funnel-Web Spiders – Related to big house spiders, they build funnel-shaped webs to trap prey. Not dangerous but can startle with their large size.
4. Wandering Spiders – Rarely seen indoors, they sometimes enter houses during warmer months. Their appearance is similar to big house spiders but they are less social and more solitary.

The main reason Australians (and Brits!) are fascinated by these spiders is their size combined with their surprisingly gentle behaviour indoors.

How to Choose One (or Manage One)

You don’t buy a big house spider, but you may want to manage their presence. Here’s a practical guide:

1. Identification – Confirm if it’s a big house spider by looking for long, banded legs and a body length of around 2–3 cm.
2. Relocation – If found indoors, use a jar and a piece of cardboard to safely move it outside.
3. Prevention – Seal gaps around windows, doors, and skirting boards to reduce indoor entry.
4. Cleaning – Regular vacuuming and decluttering remove webs and reduce hiding spots.
5. Non-Chemical Approach – Avoid spraying insecticides indoors as big house spiders are not harmful and contribute to pest control naturally.

Benefits & Use Cases

Big house spiders offer surprising advantages around the home:

• Natural Pest Control – They hunt flies, mosquitoes, and other small insects, reducing the need for chemical sprays.
• Eco-Friendly Presence – By keeping insect numbers in check, they help maintain a balanced indoor ecosystem.
• Educational Opportunity – Observing these spiders can help children and adults learn about arachnid behaviour safely.
• Conversation Starter – Their size and unique web patterns often intrigue guests, making them a “curiosity feature” for nature enthusiasts.

In simple terms, a big house spider isn’t just a large insect—it's a small guardian of your indoor environment.

2. Declutter – Open spaces make it easier to see and safely relocate spiders.
3. Introduce Plants Strategically – Indoor plants can attract small insects; keep them trimmed to avoid spider webs nearby.
4. Light Placement – Spiders often move away from well-lit areas, so bright corners and outdoor lighting can help.
5. Use Decorative Storage – Cabinets from brands like Gallery Home or Florabelle Collection keep storage neat while blending with your home style.
