A South Ruislip woman said she was 'hysterical' after she found a giant tarantula while she was cleaning her home.
Lindsay Herlihy, 32, phoned the RSPCA after spotting the massive spider but they refused to come out unless she could actually see the spider, reported The Sun .
But since the eight-legged intruder had scuttled away, Lindsay and her family were forced to go on the hunt.
She told The Sun: “I was panicking, crying and hysterical and phoned [husband] Thomas trying to tell him what had happened and I think because of my reaction he did actually believe me.”
Linday's husband Thomas finally found the monster arachnid behind a drainpipe and the RSPCA arrived to whisk the tarantula away.
The spider is believed to be a Poecilotheria tarantula from India and may be an escaped pet.
It has powerful venom, and while not deadly can cause cramps and intense pain.
The spider has now been re-homed with expert Belinda Guildford-Payn in Iver near Uxbridge .
Lindsay added: “I physically couldn't control myself because I was shaking.
“The girls were hysterical as well because of how I reacted, which wasn't good.”
