Thanks Arcadia, we didn't want all of the chemicals so i got some 'spider spray' (a spray bottle with water) and we spray it around her bed and at the door of her room and the house which settles her enough to get her to sleep. We also talked about how it means that there are no more spiders and they are poisoned which she seems to accept. I will look into getting her a mosquito net, i worried though that she would think that the spiders where in the netting, but its worth a try!
