Why does the recipe contain milk powder?
Is there a reason why you use palm oil instead of an oil like canola or rice bran?
Is the texture of the lure similar to Nutella?
Adding a bit of flour or corn starch could thicken the lure to make it harder for predators to eat.
This recipe sounds like an absolute magnet for rodents, but there are a few modifications that I think could enhance its appeal to stoats and weasels.
Adding some of Goodnatureās Meat-loversā blood-based to the mix, should increase its multi-species appeal. Insects arenāt attracted to Goodnature lures, so a recipe containing some might reduce insect interference somewhat. GNās lures are weather-resistant, so even if a small amount of one was in a recipe, it would extend the lureās field-life a bit.
Another ingredient option is tallow, which is rendered beef fat (100% saturated). Rats are primarily attracted to nuts due to their high fat content, and the inability of mustelids to store body fat puts high-fat foods at the top of the menu, so adding saturated fat to the mix would put an already potent lure on steroids. Itās difficult to smell when itās cold, but at room temperature or in the heat, tallow smells like roast beef.
Tallow would probably affect the texture of your recipe, with numerous small pieces of fat in it, but I doubt that it would pose a problem. Because tallow is hydrophobic, it would increase the lureās ability to repel water, which would give it more mold-resistance. Tallow is the ultimate winter lure, because it is very attractive to all predator species and doesnāt go moldy.
What do you put the lure into?
It isnāt easy to get thicker lures inside bottle with good nozzles on them, like tomato sauce ones, but theyāre great to use, especially in snap trap bait cups.
Cheers.
