Those of you who have used these .what bait works best on chipmunks for you.
I have used there nut gel, commercial adc baits and peanut butter. I have watched several chipmunks and pine squirrels ignore the bait inside it. I turned the trap so they can see inside it , pre baited , spread several baits just below the trap on the post its attached to. Nothing. Its been monitored with a cell cam for over a month. They seem like a good solution if they would actually get visits.

I just use a weasel box with a rat trap inside. I screw the rat trap down. Holes in both ends, I cover one hole with welded wire. All I ever use for bait is black sunflower seeds just a few in the inside and a few on the outside. I use the rat trap with the large yellow pan.

I have both the A24 (rodent) and A18 (squirrel) traps and have been unsuccessful at using them regardless of bait, presentation, or setting, even in a target rich environment. They have been very disappointing and I share your frustration.

I have been successful using rat traps in a box. I have wood boxes that hold four each and a few plastic ones that hold singles.

I’ve had great luck with them on rats, mice, and chippies. I’ve used their Nutella stuff and pb. You have to set the height off the ground correctly. Attach it to a stake. Then drive the stake in to the correct height. I only have the A24.

I've killed close to 400 california ground squirrels and 85 chipmunks with them this summer plus assorted rats (maybe 20) and a half dozen mice.

I use salted peanuts in the shell and then I fill the cap with peanut flour and screw it on.

The peanut flour sifts out some when the thing goes off and gives the next one a taste.

Don't use gooey sticky stuff, it just makes a mess, dry peanuts will knock the shitt of them.

I build an incline platform out of a 2x6, I drill holes on the top and bottom top gets a spike with a head on it and bottom gets the point to stick in the ground and stabilize it.

I want the ramp so they roll of and get out of the way for the next one.

It doesn't have to be much, I cut a foot to 18 inches and put a 1x1 for a foot hold so they can shove their head up in there.

One (This word is unacceptable on Trapperman) of a device, I've got about 20 of them out.

Thanks. I will try that. I haven't gotten a single taker on any of the bait I've used.

It sounds like you’re setting too high. Mice, chipmunks, etc aren’t that picky. Rats can be.

I think rats are wary of new things in their environment.
I've heard that from others and it squares with my exoerience.
