not much as far as bugs and things go. I figure I am way bigger than they are. Snakes use to but a really weird thing happened , I had surgery and ended up in a coma for a week, when I woke up I wasn't afraid of snakes anymore. Even bought my DGD one and handled it. It was only a gopher snake but at one time one the size of a worm made me lose it to the point I scared everyone around me.
