Scientists today confirmed that they've seen an alarming rise in Noble False Widow spiders across Ireland.

Research conducted by the NUI Galway has found the species is actually capable of producing many of the same deadly toxins found in real Black widow venom.

The name 'false widow' refers to its appearance, strikingly similar to 'true' black widows with their characteristically dark, shiny, bulbous abdomen.

The relationship goes beyond their looks - they are in fact, closely related.

Though traditionally viewed as non-deadly, in parts of Ireland and the UK, it is now one of the most common spiders found in urban settings.

If you were unlucky enough to be bitten, symptoms range from mild to debilitating pain and mild to intense swelling. Some victims have experienced tremors, nausea and impaired mobility.

Dublin seems to be one of the most 'rampant' spots. Most people who get bitten are either in their bed, or putting their clothes on in the morning.

Best practice is to shake your clothes and bedding before getting ready. WOW, that's not scary at all!

Where is the False Widow spider originally from?

The species originated in the Canary Islands and Madeira but has been spreading worldwide in the last two decades.

It's believed that they made their way into Ireland in freight containers and have spread to all parts of the country since being detected here in the late 1990s.

A genetic mutation within the species may have made the False Widow more adaptable to new environments.

What to do if you see a False Widow spider?

If you do see a noble false widow spider, you can remove it by placing a glass or other receptacle over the top of them, and then sliding a piece of card under the container.

Pick it up carefully and release it outside, preferably a little way away from the property if possible.
