What is Spider Season in the UK?

Spider season in the UK typically runs from late August through October. During this time, you’re more likely to see large house spiders scuttling across your floors, walls, and even appearing in the bath. This increase in sightings prompts a common question: when do spiders usually come out in the UK?

Male spiders leave their nests in search of mates, which often leads them inside our homes. Warm interiors and undisturbed corners provide ideal conditions for them to settle.

Why Do Spiders Enter Homes During This Season?

Spiders are attracted to the warmth and shelter inside homes as temperatures drop outside. The presence of small insects, such as flies or midges, can also encourage them to stay.

If you’re wondering when spiders stop coming into the house, the peak usually ends by mid-autumn, although some stragglers may appear later.

How to Prevent Spiders from Entering Your Home

The best way to prevent spiders from coming in is to seal up entry points and reduce attractants such as food crumbs and other insects. However, the most practical solution is to install insect screens for your doors and windows.

Fly screens for windows  & door fly screens  act as a physical barrier, allowing ventilation while stopping spiders and flying insects from getting inside.

Is the UK’s Spider Season Getting Worse?

Reports of increased spider sightings suggest that changing weather patterns, milder autumns, and urbanisation may be contributing to longer or more noticeable spider seasons. That’s why it’s important to be proactive with prevention, especially in spider-prone households.
