Good luck sleeping tonight because feared venomous False Widow spiders are taking over one Dublin area.

The giant and highly dangerous arachnid has become 'rampant' in Dalkey and surrounding areas with the foreign beast constantly on the look out for its next victim to inflict pain upon with their horror bite.

The false widow originally comes from the Canary Islands but has been spotted in Ireland for the last few years after first being sighted in Bray in the 90s.

A number of Irish people have been hospitalised due to bites from the spider in recent years sparking fear in many across the country.

The snap was posted into a local Dalkey group with residents warned to keep an out for the not so friendly neighbourhood spider.

The deadly False Widow

She said: "This is my best photo of a False Widow, taken yesterday in my front garden, the only venomous spider in Ireland. From what I can see they’re rampant in Dalkey and surrounding areas and are taking over from our lovely harmless native spiders.

"Anyone else had any experiences with the False Widow spider in Dalkey?

"They’re not camera shy, they can be quite vain so don’t be afraid to go up close for a good shot. Oh and they normally hide during the day and only come out at dusk."

Here's all you need to know about the eight-legged critters;

What do they look like?

In appearance, most false widow spiders are a brownish colour with pale markings and round bulbous bodies.

The females are larger than males and can measure up to 15 millimetres while the males measure up to 10 millimetres.

Where will you find them?

You'll most likely find the spiders outdoors in the bark of trees but as proven by the storm of pictures of them making themselves at home lately, they do sometimes venture indoors.

False widows can be found hiding in window frames, sheds, and warm areas indoors like bedrooms.

The creepy crawlies also like toilets, kitchens, lofts and conservatories.

How dangerous are they?

New Irish research has found that the spided can potentially deliver a very real dose of dangerous toxic venom to its victims in one bite.

Scientists from NUI Galway   and the University of Liege in Belgium discovered that the Irish spider produces many of the same toxins found in real Black widow venom.

As detailed in the research released in the Journal Toxins., 111 out of a total 140 toxins recovered were found in both species of the spider - including compounds that attack the central nervous system.

If you're quaking in your seat and checking your house for spider points of entry, you shouldn't be overly worried. Lead author of the research, John Dunbar said the likelihood of getting bitten by one isn't very high, even if the news of two women being hospitalised by one is a scary thought.

Dunbar said: “Although our study shows that the venom of false widow spiders may be more potent than previously thought, it does not mean we need to fear them.

“In many parts of the world even ‘true’ black widow bites rarely require medical attention.”

“However, this new discovery will ultimately help medical professionals to diagnose and treat severe false widow bites.”

A bite by the creature will usually cause swelling and redness, but doesn't usually result in any long-lasting side effects.
