Applied in my vegetable gardens as described. Heavy rain next day so was well embedded. Two days later half of my broccoli plants, 3 cauliflower, and all but 2 spinach were gone. Yesterday found 7 more broccoli and all but 5 cauliflower gone. Obvious gopher damage. This morning, they're all gone and the hole I dug to the gopher tunnel was filled in. Was it just not enough time to work? Don't know yet, but now I'm watching for activity with my crossbow.
Will see how it works on the moles.
They were still active even a week later, making new holes and mounds. I saw Gopher lay right down where it had been spread, didn't bother them a bit. Waste of my money.
