If she really can't stand to be near bugs, even in an insect house (and I know how she feels, am the same with spiders!) I saw a great idea on TV years ago where a girl was being treated for arachnophobia (sp?) First they showed her a cartoon of a spider that really looked nothing like a real spider and asked her to touch the screen, they then progressed through more cartoons that became more and more realistic, continuing with touching the screen, then they went on to photos and finally videos before she went to an insect house and was eventually able to be in the same room as a 'loose' spider, maybe a scaled down version of this would help?
