Residents of a seaside town have been warned to keep an eye out as the terrifying false black widow spider has made multiple appearances recently.
Locals in Dalkey, south Dublin have reported many sightings of the venomous spider.
There are no indications, however, if they're male or female - the female bite has a stronger sting.
The spiders have been causing fear across Ireland, with reports earlier this summer of bites in Waterford and Kilkenny.
Sharing a zoomed in image of the eight-legged terror that they found in their garden with a local group, one man said he will be wearing garden gloves from now on when outside.
He said: "Just to be aware found this morning in a coiled up hose in garden. It's a False Black Widow, they are aggressive and give a very sore bite.
"Not fatal like their Aussie cousins but can have complications.
"Definitely wearing garden gloves from here on. Normally I capture spiders and release them but this guy (or girl) is going to get the chop!"
It seems that the creepy crawlies are making more and more appearances in the capital, Dublin Live reports.
Some even said that most of the spiders they see are the false widow.
One woman said: "They are very common here now.. I've so many in my garden and they like to come into the house a lot!"
While a man added: "I’d say 6 out of 10 spiders I come across in garden and shed are these guys."
It seems that they still have a tendency to bite, with many warning against the infection that comes with it.
One man said: "Be very careful of them, I got a bite from one, when I was asleep. It got infected and I had to go on antibiotics for two weeks. They are vicious!"
While another added: "Got a bite from one of these. VERY sore and lasted for weeks."
And it seems that a bite is not the only risk - as the spiders like to play mind games.
Another woman said: "One on the wall of our house last year jumped at me and kept swinging towards me on a strand of web - terrifying! He made quite a mess when I eventually squashed him!"
