How to keep my dog from eating bugs?

Our porch is littered with dead june bugs that fly into the door and die. My lab thinks that they're tasty treats apparentally, because she will try to eat every single one. She'll pick one up or sniff at it, I tell her no, and she moves on to the next one. It's a constant battle and if she does eat one she'll end up puking all day. Every morning I sweep them into the grass where she's too lazy to pick them out, but it would nice if I could take her on a walk without having to stop. How can I get her to stop for trying to eat them for good?
