Michaela Egan with her two children George, one, and Ella-Mae, five - the mum found a Tesco banana full of spiders. See MASONS story MNSPIDER; A mum-of-two fears she could have a family of the world's deadliest spider living in her home after she found a suspected nest on her BANANA. Michaela Egan, 24, bought the pack of fruit from Tesco last weekend and four days later she found the spider's webbing on the last banana in the bunch. The full-time mum who lives with her partner William Osborne, 26, a postman, took a photo and immediately posted it on Facebook to ask for people's advice. She posted the photo on a local community page and within minutes she was inundated with messages from other users suggested it was the Brazillian wandering spider - which are known to nest in bananas.
