I have used fishing line to hold a bait cup or a piece of fruit in place just past the trip plate. Fruit works well, used some damaged peaches or apples off my trees, or even a piece of cantaloupe rind (worked great, fragrant). PB is another good bait.
I have had to work hard to protect my orchard (peaches, pears, apples) and garden for years. No one has bothered the figs yet except ants, yellow jackets, beetles. But I trap critters all summer. Last year I caught 3 coons in 4 nights, had no more problems from them. This year I have caught 7 groundhogs, 2 squirrels, 2 rabbits, 1 coon, and unfortunately 2 skunks. I generally take them al out to a county park about 8 miles away and release them, except the skunks.
Good luck Dave
