Save your $12 and don't buy a bear bomb. Tonight I sat on one of my bait sites that was hit recently and tried out a bear bomb in Anise Oil scent. I rebaited the site, and set off the bear bomb just before I got into my stand. It stopped spraying before I got into my stand which is 40 yards from my bait where I set the can up. There was virtually no odor at all, and I had no bears come in tonight.
