False widow spiders call outs on the increase, says LNPS
BPCA member London Network for Pest Solutions is advising property managers to be on the look out for false widow spiders in London and Essex.
bpca.org.ukHere’s the latest I can share based on recent reporting.
-
The noble false widow spider (Steatoda nobilis) continues to attract attention in the UK and Ireland, with several outlets noting a rise in sightings and related bite admissions in the last few years. In England, hospital data suggest a trend of more people being treated after bites, reflecting both increased spider activity and heightened awareness. In Britain, pest-control networks have highlighted London and Essex as areas with notable activity and ongoing infestations in some urban settings. These developments are commonly framed as a growing but manageable public health and pest-control issue rather than sudden, extreme outbreaks.[2][3][4]
-
In Ireland and the UK, reports and studies have documented the spiders feeding on vertebrates in rare cases, underscoring their widening predatory range as their urban presence expands. Notable examples include evidence of noble false widows feeding on vertebrates such as small mammals and bats in some documented cases, with researchers calling for public reporting of sightings to better understand impacts. Such cases are uncommon but have been repeatedly cited in academic and popular coverage to illustrate the spider’s adaptability.[1][6][10]

Public guidance commonly emphasizes calm and practical steps: reduce clutter and secure web-prone areas, seal entry points, and consider professional pest control if infestations are visible or bites occur. Health guidance urges people to treat bites with standard first aid and seek medical care for significant reactions, especially for children, the elderly, or those with allergies.[3][4]
If you want, I can:
- Summarize the main takeaways for homeowners in Los Angeles (your location) with practical prevention tips tailored to that climate and urban environment.
- Pull the most recent UK/Ireland sources and extract key numbers (bite admissions, sightings) into a quick bullet list with dates.
- Create a simple chart showing the trend in hospital admissions for spider bites over the last decade using publicly available numbers (I’d need to compile them from sources you’re comfortable with).
Would you like me to proceed with one of these options?
