if you have the ability to age some ground meat underground for 30 days i love ogormans montana bait solution. taint 1 gallon of ground or chunked meat (i use either beaver or bobcat)for 30 days underground. dig up, mix in one pint of the above mentioned solution and viola. it stops the taint by preserving the meat and adds some goodie smells such as beaver castor, rat glands, and skunk jizz.
i make at least 1 gal each year whether or not i am going to get a chance to use it and run out every year as if i dont use it buddies steal it off me. works great on cats, yotes, fox and ive had enough wolves visit sets to know it will work on them as well. when it is all mixed up i leave it in the 5 gal bucket for 5-6 more days mixing it well once per day. then i simply place it into 10 oz plastic bait containers and seal them with a couple wraps of black electrical tape and place them in a different clean 5 gal bucket and seal the lid. for the most part i believe this gets better with age, so i make it 1 year ahead of when im going to use it and let it sit in the bucket till the next season.
it will remain pliable and useable down to about 0 degrees F, but you can add an antifreeze and a little more skunk jiz to make it work down well below -20/-30 F.
another great LDC which can easily be made is to melt down 1 pint of vaseline either in the microwave or dbl boiler. while that is melting (takes like 8 minutes in the microwave) you can add 1/2 oz pure skunk quill to ea 4 oz GLASS widemouth lure container. When the vaseline is melted simply pour enough into each GLASS container to fill it up, leaving 1/4" air space. Put the covers on and run a couple wraps of black electrical tape over the cover/container seal to trap in the lovely smell, then immediately shake like crazy and place in the freezer. you want it to solidify asap to elliminate any seperation. every 10-15 min take them out, shake like crazy and invert it 90 deg in the freezer. when it is solid take out and its ready to use right away. this is a very powerful ldc so use it accordingly and dont haul it in the cab of your truck!
there are better bases than vaseline, but for the most part vaseline will work as well so why spend more.
