I used a couple of strategies with DD's insect fears. I try to normalize the bugs by getting close, watching them, picking them up, etc. After a while, she wants to get close too and is excited about them--after a few months of this, she'll coax a spider onto a piece of paper in order to move it out of the house and into the garden. With flies, I make it humorous and start talking to them. In my silliest voice I say "hey fly, you don't belong in here, this is Anneke's house, you belong outside with the birds and the trees and the flowers." And now she no longer freaks out when she sees them and she starts trying to talk them into flying out the back door. With bees, we talk about how lucky we are to have them around since they make honey--we watch them flying to each flower and talk about how they're picking up the flower juice to bring back to the hive and make honey. With ants, we talk about how they must be on their way to the ant picnic since they're carrying things, and now she's excited to see them too. And I never step on or swat the bugs (I just move them to their "bug houses" outside). I hope that helps!
