Well after nearly a year here it finally happend - our 9 year old son was bitten on the arm by a white tip last night!
He had left his pj top on his bedroom floor and when he put it on last night the spider was waiting!
We put an ice pack on right away and phoned GP Plus for advice - Doc said not to worry too much and just watch for allergic reaction. Within half an hour the pain was gone.
Never seen the boys tidy their rooms so fast! Oh and that particular spider won't be biting anyone else :p
