Is there anyone that sells bait in bigger quantities.I need something bigger than a pint.

Keg creek, gallons and half gallons. Good stuff at a good price.

Check out Billingsley Brand Lures. I'll bet Dale can fix you up with what you need.

Appleroad baits. https://www.appleroadlures.com/product-page/apple-road-bobcat-meat-bait

MTP sells 2.5gal of muskrat or beaver or bobcat, your choice. Comes preserved and fresh and you can add what you want. And it’s under $50.

What kind of bait?

Your a trapper and you buy bait,lol.Make some up with some of your carcasses,I guess you have to use some kind of preservative,or dry/smoke it for your climate.
It is cold here now,and I spent an hour making up bait today.
I have a bait shed full of frozen carcasses some fresh and some tainted.
I chopped up some fresh beaver and some tainted beaver in fist sized chunks for the marten boxes.
I chopped some fox lynx and otter carcasses in half for trail sets and I have a bunch of whole beaver carcasses for jackpot bait or to chop later if I need to replenish the buckets.
I also chopped up some marten carcasses for extra castbait at the jackpots.
I like chopping bait before it gets frozen like concrete.
Tomorrow I go out to feed the pets,lol.

When we were kids we would go out in the spring for the sucker run and net and snag hundreds of suckers and dry some and freeze a bunch in burlap bags in the deepfreeze for trapping bait in the fall and winter.
Its all free for the taking just a little time spent getting it- there is so much of it all around

I've been having excellent results with cavens.

Agree with Boco make it , I like to taint excess venison scraps and add sodium benzoate if u want to hold it.
