I use marshmallows and Caven's moonshine lure, DP is filled to the brim but raccoons leave the bait at the bottom untouched. what do I do about this?

Might be mice.

Very likely.
If a coon is eating that much out of the trap it ain't going to stop until its all gone.

Buy you some COONDAGGERS !!!

Why are you filling it up?

Unless your DP’s aren’t functional, it ain’t coons.
Put just enough whatever to cover the trigger. If they hungry, they’ll find it and get caught.

I use duke dp's with no trouble .Marshmallow under trigger ,half full of flavored dry cat food ,never a problem .Try a slice of garlic bologna instead of marshmallow wedged in bottom under trigger ,then dry cat food.

Birds ?

Mice. Agree there's no reason to fill a DP. Your wanting to catch them not fatten them up.

thanks for the tip, i didn't know not to fill them to the brim, just though it may keep them working the set longer

X2. Fill to the trigger or just below. Put a golf ball on top, it'll stop the mice. Coons will have no problem knocking them off. I don't set a dp without one. I've made a habit of picking up random golf balls I find while shed hunting. No matter what woods I am in I can always count on finding a couple golf balls in the middle of nowhere.

I like a Gatorade bottle over the top of the trap , then when it rains and rains and rains I am not dumping out bait to reset

the liter Gatorade bottles work nice , clear bottle , orange cap you can see the bait through the bottle and the orange caps are easy to spot
I cut the bottom out they fit over the dukes very well.

I don't drink Gatorade any more so I need to find someone who does and get them to collect them up for me.

When I’m trapping the river in my boat I like to put one large marshmallow under the trigger and one sideways half sticking out of top of DP. Shot of fish oil on top mallow and a bit for trailing if necessary. The top mollow helps keep mice out and lets me check at a distance while driving by in the boat. Amazing how well that marshmallow sticks out, unless it snows of course!

Nice for sure but only need some bait under trigger and put some fish oil or paste on the trap lip , make them work

Agreed, but how can you tell if mice cleaned you out? Without investing each DP close up that is.

If the bait is gone and the trigger ain’t tripped, it’s either mice/rats/flying squirrels. If you really want to know, set that joker with a hair trigger. Hair trigger being the dog barely in the notch. You catch whatever is stealing your bait, lol.
And by only filling up to cover the trigger, you’ll catch quite a few coons by both paws.
