People living in the Cork town of Carrigaline have been warned after a photo emerged showing a False Widow spider in a resident's home.
The picture was posted on the Carrigaline Notice Board by a curious local who wanted to know if the species was dangerous.
However, residents quickly informed them that the species was in fact a False Widow, a spider that can be quite dangerous to humans with the bite being quite painful, Cork Beo reports.
