A photograph is more useful than a guess
Many spiders are misidentified. Take a clear photograph from a comfortable distance and describe where it was found. Avoid making a medical conclusion from a spider sighting.
Manage the immediate area
Keep the location accessible for inspection without handling the spider. If frequent sightings concern you, ask for identification and advice on the surrounding conditions.
If you have symptoms
Use NHS guidance or an appropriate healthcare professional for bites or a concerning reaction. This website does not diagnose bites or recommend medicines.
