I know sodium benzonate wont do it
Sodium benzoate has mold inhibiting properties in it. It might not be the best mold inhibitor but it does work. Salt & Alcohol will do the same thing as well.
Common mold inhibiting / preservatives easily obtained from trapping sites would be sodium benzoate, methylparaben, and potassium sorbate to name a few. Possibly a few more if you ask. Or you could reach out to companies who specialize in them to give you more of a variety. FYI..Some will significantly alter your bait.
Key words "might not be the best" but.....
Sodium Benzoate has some mold retarding properties.
That's all I was stating... has them. May not be the best but in regards to the posters original post in that it doesn't work. It does work to some degree.
Then one poster typed about a gallon of bait. SB should have no problem with a gallon of bait, but the poster didn't specify what he was using it in. Methylparaben has always been one of the top 5.
jmo imo imho jm2c
