Giant Spiders 'Size of Human Hand' Have Record Breeding Year in UK

What's Happening?

The UK has seen a record-breaking year for the breeding of giant house spiders, with sightings of the eight-legged creatures reaching unprecedented levels. These spiders, which can grow to the size of a human hand, have been spotted in homes, gardens, and even public spaces across the country.

Reasons for the Increase

Several factors have contributed to the surge in spider populations. The mild winter of 2022/23 allowed spiders to survive and lay eggs in greater numbers. Additionally, the abundance of prey, such as flies and other insects, has provided ample food for the spiders.

Climate Change Impact

Some experts believe that climate change may also be playing a role in the increase. Warmer temperatures and changes in precipitation patterns can create more favorable conditions for spiders to thrive.
