To prevent moles from coming back, you’ll need to remove their major food source which is usually grub worms.

To permanently remove grub worms, apply milky spore to the affected areas each spring, summer and fall for at least 2 years in a row.

Milky Spore is a naturally occurring microscopic bacteria (Bacillus popilliae) that kills Japanese beetle grubs before they can grow into ravenous adults. It’s a long-term solution because it survives winter temperatures. The Milky Spore population increases each year, reaching peak effectiveness about three years after application, and lasts ten years or more.

  1. when you have moles tunneling in your yard they are usually after white grubs. destroy the grubs and the moles move away. this is a case of spending more to get better value.

    i recommend milky spore is a bacteria that specifically goes after white grubs but is harmless to people and other animals.

    the value to this is it does not poison the environment and the effects of one application last 15-25 years.

    Shop around, I know you can get it off of Amazon.

      I almost spent the money for milky spore bacteria one year, but checked with my local Master Gardeners first. I’m glad I did as I was informed that it rarely lasts for more than one season in our northern climate.

      Moles do not only eat grubs, so getting rid of grubs does not garuntee getting rid of the moles!

      Awesome, thanks for the tip. I not only have mole issues, but wild pig issue. They too are coming in for the grubs.

      Work for garden too?

      I’m guessing yes and can be tilled in when I do spring tilling.

      I tried milky spore and it did not work to get rid of the moles/voles.

      • I tried milky spore and it did not work to get rid of the moles/voles.

        Milky Spore will only work if they’re feeding on grubs, as the point of the spore is to kill the grubs themselves, thereby removing the foodsource. They also love earthworms, so if their main diet is actually consisting of worms, you’re out of luck.

        Hence the recipe we shared 😉

      After years of fighting the moles, I went big time, ripped up the lawn dug down put in 1/2″ galvanized steel mesh dug down deeper, around the edges down two feet put a two foot wall of steel mesh around the perimeter, and back filed with top soil, layed sod, result nice green lawn, zero mole holes.

  2. sounds like great ideas for repelling moles! i’ll have to go find some castor oil and try the first remedy, because i think we are too far into the cold season to apply milky spore right now. in the spring i’ll try milky spore for a more lasting recipe.

    thanks!

    • I will try both and get back to you all. The moles are destroying my yard.

      Did you try this? How well did it work?

  3. :springsmile:

    thanks for the recipe, its getting warmer out and this is the first thing i’m gonna do in the process of restoring my lawn. hopefully it will drive the tiny little pest away from my yard.

    today is a new beginning, another day to give thanks and praise. :occasion16:

    • What is milky spore- my daughter and son in law have a big problem with moles

      Milky spore is an organic product that you can buy to kill the grubs in your lawn and soil which in turn will make the moles leave. The only reason you have moles is because you have their favorite food living in your lawn. If you kill the japanese beetle (the grub stage) the moles will go away permanently.

  4. in my backyard area i have tons of holes, some are really deep and others aren’t. i was told snakes make these holes. could that be true?

    or is this a family of moles digging these aggravating things?

    i know my neighbor says her cats kill moles in her yard so they have to be in our neighborhood. the snake issue scares me as i’m highly phobic. thanks for your help.

      Actually if you’re in SC, chances are they’re ground spiders. They make little “trapdoor” holes to catch prey.

      my “chemical guy” applies grub control once or twice a year. it has done no good whatsoever. i’m told it does not kill earthworms which is also a good source of food for the moles.

      last year we once caught 9 moles in a 9 square foot area with traps. They used old tunnels mostly. This time we cannot seem to catch a single one.

  5. we have suffered with moles for 2 or 3 years, now. Our once beautiful lawn is really a mess. I am going to try both of these ideas.

    It is now August…will it do any good to use Milky Spore now?

    Or should I wait for Spring?

  6. we are going to try both and find out if it works. we bought a mole trap and what a waste of money. will inform our neighbor as she has the same problem.

    have to do something as they are truly destroying our yard.

    thanks for the info, and will let you know the results.

  7. hello…. has anyone else tried, and found these things worked? my moles have become a bad thorn in my side!!we bought the whirlygig sort of things, and placed 2 in what we call our field in front of our home.

    The did leave that area..

    but… they moved into our yard!! I understand they are after the grubs, and maybe the constant vibrations of the whirlygigs, just moved them further away?

    We also tried the traps to no avail!

    I like both these remedies because I try not to use chemicals. I’ll try the castor oil remedy/recipe now. Sure hope it works!

    Thanks!!

      I was just looking on this site and saw the problem you were having with moles, it’s just like ours. Did you ever resolve it? Did you try the Milky Spores?

      Thanks.

  8. thanks for the tips on getting rid of moles. the moles have taken over in our yard and its time they move out! thanks again!

  9. beware that moles have babies in april so try to get rid of the offenders before then our you’ll have many more to kill.

  10. how does this mole repellant using castor oil and detergent supposed to work to get rid of moles anyway? i’m rather curious. do you just pour it on the mound they push up from their tunnels?

  11. i have found the best mole or vole repellent is to put peppermint essential oil on a bit of cotton and put it in in one of the mounds. i had tried every tip imaginable to no avail. but, they hate that peppermint.

    you can also use peppermint oil that you can get from your pharmacist or at hobby lobby in the candy/cake decorating department.

    i would really like to use milky spore but the price is a bit steep for my budget right now.

  12. i used moth balls. just drop one in each hole you find. i flower gardens or vegetable gardens, plant 3 moth balls at the end of each row.

    I had a peanut garden and they were eating them. A friend told me to do this and within a few days, I had dead moles allover my yard.

  13. We have both moles and gophers on 20 acres and they are here by the droves… Does this mixture kill them or just discourage them? Once the mound is formed it seems we may be too late to catch them before they move on..

  14. Whenever moles/voles begin tunneling around our fruit trees or in our garden, we get some juicy fruit gum and tear off little pieces and push it down in their tunnels. They eat it and die underground. It has always worked for us in Va.

    and its cheap!

  15. Is the castor oil and detergent recipe safe to use for moles that are tunneling under my vegetable raised beds? I do use Dawn detergent and epsom salt for killing weeds, but cannot use it around vegetables or plants/flowers.

  16. I’ve tried milky spore – applied every 4 months for 2years. Used juicy fruit gum, moth crystals, castor oil spray containig peppermint oil. Nothing works!

    Have also used the “peanuts” placed in the runs. I guess the best remedy was a dog I had that would dig them out and bring her “gift” to me…(yuck) That worked till I lost her due to age and illness. Only thing I have not tried is the live traps.

    Ground becomes unstable when we have an lot of rain. I’ve talked to pest control as well as professionals in the city where I live. They just shrug and shake their head.

  17. We are in a new home community. Our front lawn never has had a mole dug up, but our back lawn is terrible. The past two years, the homes that have had sod put down, have never had not one …yet.

    But they love our lawn and our neighbors. I work hard on our lawn, but by mid summer I give up and let them win. It becomes dangerous to walk back there as the underground tunnels give way with the weight of our feet/shoes.

    Late summer moles decided to come so close to the house they were actually digging up my flowers with their piles of dirt left behind. There does seem to be ant hills nearby the areas, so my thinking is to get rid of the ant hills, maybe they will just go away? Has anyone actually had success with anything?

    With my grandkids around often, we need to be careful what we use. We have tried everything other than digging up the whole lawn and starting over. As moles seem to leave new sod alone in our area.
    I see this has been an issue for years for many.

    With living in the midwest and winter still here, I want to be as proactive this spring as I can.
    Thanks for anyone that can give suggestions. I live on you tube for suggestions, and nothing has worked so far.

  18. Hi, I tried to read all the post here on moles and I don’t believe this suggestion has been mentioned. With many years of bad mole problems and lots of $$ on poison peanuts, ect. and still moles, I had a bad attitude with them.

    Two years ago, I was chatting out in the yard with a local Veterinarian who stopped by the Yard Sale I was having. I mention the mole problem. He said he was raised in the country here and the country folks would do this.

    day one: stomped down all the fresh mole hills you can.
    day two: find the new fresh hills made overnight. dig a small hole in the top of one. put water hose into hole and let it flood them.

    you might have to do it in a couple of places if your covering a large area. repeat when needed. this was just to simple!

    i didn’t think it would work. of course its not permanent, but this work better and faster than anything else i’ve tried. hope it can help.

  19. Moles, I live in the country (Wisconsin) and have them all the time. Last year I trapped 21 of those buggers. I’ve tried every type of trap, waste of money until a friend of mine who works at a golf course told me to buy “No Mole” traps.

    https://amzn.to/2rZK7xs. I have 8 of them now.
    I set two traps at each long run, one in each direction. About 30% of the time I get two money per run.

    You never know which way they are running.

    I’ve tried castor oil, peppermint oil and cotton balls, they only move onto a new area. Trapping is it. Follow the instructions, use latex gloves when doing setting them.

    If you set only one trap in a run, you’re not gonna get the best method for removal. Good luck
