Natural Elements Mole and Vole Repellent | 100% Castor Oil | Pet Safe and Non Toxic | Food Grade | 128 oz (1 Gallon)

Seems to be working! I was skeptical, after having used several other things to try and rid my yard of moles. I sprayed my front yard three times with one gallon mixed up following the instructions. I mixed it into a 15 gallon spot sprayer. Within at least two weeks of the second application, I noticed a marked reduction in activity and since the third application, I haven't seen any activity in my front yard. I'm going to get a second gallon to treat my back yard and hit the front yard again. Just be aware, this is, obviously, an oil. So your grass will be a bit slick after applying it. It does have a slight odor, but not a chemical odor or anything like that. I wouldn't apply it right before a heavy rain, but maybe when the grass is slightly damp (e.g. heavy dew or right after a rain...) as it may help it soak into the ground quicker. I applied mine about 4-6 weeks apart. I used the "finest cheapest" store brand dish soap (will help it mix in the water for spraying).

I use it once and the voles did not come back

This is not a solution to mole/vole infestations but it will help keep them away after trapping/fumigating. I use this with my CO2 gassing machine. It coats their tunnels and seems to keep them away for a while. Anything is a big help when you have a bad infestation. It's all natural so it won't harm the environment. There is no noticiable scent for humans but probably a nasty one for Voles, Moles or Gophers. I have a gopher problem and castor oil is a good repellant. So it's effective for my application.

I have tried everything over the years to get rid of these obnoxious critters. Since I have a very large yard and water is expensive I opted to use the Castor Oil differently. I used Castor Oil, dish soap and a few other ingredients. I poured a little bit of my concoction down into each mole mound that I found. It’s a process that I have had to do daily. To my surprise I have managed to herd the moles off the grass and flower bed's. And I still have some Castor Oil left. I also discovered that moles are attracted to bird feeders. We had one in our backyard and the moles ruined our grass and beds. We took it down and the moles haven’t returned. If you have the patience and time I recommend using this product and my method.

Don't mash the tunnels, you'll need them as a guide for applying the recipe. I mixed it with a couple other things, then i mixed just half the water in the recipe, poured that into a countainer, and mixed it up (shook it). I let it set for about a week and a half. We've had alot of rain, and you have to spray the ground when the ground is just right, and also it's best if it's going to rain the next day after application. Day of application, i sprayed (just outside the parameter of their digging, and making sure not to spray an area so they could exit, then i sprayed the top of all the active tunnels except one that could take them to their exit). So i added the additional water to the concotion that'd been sitting outside and poured it into a cheap $10 hand held sprayer. NOTE: my recipe calls for a very small amount of this somewhat expensive product - but it's been worth every stinking penny. I sprayed almost a quarter of an acre area and had some left over. IT WORKS! Within a weeks time, no more digging into my yard all slong the fence line. No new tunnels, and i can literally see where they exited my yard. My following the recipe then learning how to apply it really paid off here. Now you can go mash the tunnels. Now i'm curious how long it will last, but i'm pretty sure i'll have to reapply since I've learned that the first application should be BEFORE they start digging, early Spring.
