Burrowing animals such as Moles, Voles, and Gophers, are notorious for destroying the root systems of landscaping shrubs, flower beds, and vegetable gardens. It's natural for moles to create two types of tunnels. The first, are feeding tunnels. These run just below the surface, and appear as raised ridges above ground. The second type of tunnel is dug deeper, and unites the feeding tunnels. It also creates molehills, and is often the signal that you have a pest problem. We found a few people this summer who had this challenge, and asked them if we could review the results after applying a mole repellent to their inflicted areas.
For our tests, we used "Root-Saver" mole repellent from Repellex.com. Repellex Root-Saver is a deterrent available in granular bags, and a ready-to-use 100% organic liquid form. Root-Saver targets moles, voles, and gophers, but also states it's, "ideal for skunks, field mice, woodchucks, and other burrowing animals"... even armadillos.
Active ingredients are used to dis-flavor food sources, and create an uncomfortable environment. The liquid form includes Castor Oil, Sodium Lauryl Sulfate, and Potassium Sorbate. Paprika and water are listed as inert ingredients. Granular Root-Saver combines Garlic Oil, Castor Oil, Paprika, and Wintergreen Oil. The included emulsifying agents allow the mole repellent to penetrate through the soil, which allows a pest-free environment for up to 90 days. Our tests were conducted in an iris garden, a vegetable garden, and the lawn of a backyard.
Gordon tried the granular version on his back lawn. "I've had moles in the backyard, ever since we moved into this place two years ago. They'll leave molehills, which become a nuisance when mowing. I already had a spreader I've used for fertilizer. The bag had easy-to-use instructions, and even included directions for specific spreaders.
After a week of spreading the repellent, I actually noticed an increase of molehills. I'd read that this could be expected, because of increased activity. After about three weeks, the hills were about gone when mowing. We have a field behind us, and they moved there."
Janet used Root-Saver on her iris garden. "Last year I lost a few iris to moles. They ran a path straight through the North corner. When it was announced at Garden Club that Mike (editor of allrepellents.com), would provide mole repellents to any member with pest problems, I grabbed a bottle.
There was activity just outside the garden, and I was worried the moles would move in. The bottle easily hooked up to a garden hose for spraying. I probably used only 1/3 of the bottle. I sprayed the iris, and surrounding area as suggested. The activity moved behind the fenceline. I'll use Root-Saver again next year, even if I don't see activity."
Similar results were seen when sprayed around a vegetable garden. Mole activity moved.
Our reviewers were all happy with the Root-Saver Mole, Vole and Gopher Repellent. Root-Saver is available online.
