Peggy, I used peanut butter. The first batch I didn't put on too good or very much. You got to jam it in the hole where the trigger is. Sometimes they can still lick it out but eventually they DO get caught. I believe putting more on there helps too.
Gluing the dog food to the trigger? That's a hoot!

Sounds like it might work though.
Update: I checked them this morning and again this afternoon. The two I could get to (on the bench and under Ole Booger's seat) still had the peanut butter on them. That's a good sign. I'll be checking the one on the garage floor later on when I can get to it.
About Jake, I've only seen the tail end of him crawling back into the woodwork. His skins are almost 6' long. About 20" from his tail he is about the diameter of a quarter or more. I hope he didn't get caught by the first trap that 'crawled away'.
Rance
[Edit:] Just checked the third trap. Someone has been licking on it but I must have interrupted him. Looks like there's still one lurker left.
