Milky Spore Lawn Spreader Mix - 20 lb.

The product picture shown above is the NEW packaging for this product. Some websites still display the older, dark blue and yellow bag with a large grub on the front. The product is the same.

Milky Spore for Grubs provides safe and effective grub control which can remain active in the soil for as much as 20 years. To get this long lasting control you should apply Milky Spore at least 3 times a year for 2 years. You should apply Milky Spore grub control granules with a push spreader or a hand spreader in the Spring, Summer, and Fall for 2 years to create the long term residual. Each 20 lb bag of Milky Spore will cover 7000 square feet. Milky Spore is safe to use along with other herbicides and fertilizers and it is harmless to birds, bees, and fish. Safe to use around pools or ponds. Milky Spore contains Milky Spore disease bacterium (Bacillus popillae) that kills grubs in a way that is environmentally safe and highly recommended by professional and organic gardeners.


Active Ingredient: Spores of Bacillus Popilliae 0.02%
Target pests: grubs (Japanese beetle larvae)
Yield: One 20 lb bag will treat 7000 square feet
NOT FOR SALE TO: FL, HI, ID, LA, MT, ND, NM, SD, UT, WA, WY
Special Features: Will stay and protect in your lawn for 15 to 20 years after just 6 applications over 2 years.

MILKY SPORE -- Frequently Asked Questions:

1. How fast does the Spore work and how long does it last?
Milky Spore begins working as soon as it is applied as long as grubs are feeding. Once grubs are infected they will multiply the Spore by several billion times and spread it further. In warm climates good control can occur in one to three years. In colder areas like New England, three to five years. Once established in a lawn, Milky Spore has been known to last 15 to 20 years.

2. Will freezing ruin the Spore? What about heavy rain?
No, Milky Spore is not affected by freezing or other adverse environmental conditions. Heavy rain may wash away newly applied Spore dust necessitating retreatment.

3. Will fertilizer or chemical pesticides that have dursban and diazinon in them affect Spore?
Dursban and diazinon have been banned by the EPA as toxic to the environment. Milky Spore is safe for the environment and is not affected by pesticides, fungicides or herbicides. They may be applied at the same time.

4. Can I use it in the vegetable garden?
Yes, Milky Spore is harmless to food crops. It is not a chemical pesticide. It may be used in gardens, around pools and wells.

5. Should we keep our pets off the lawn?
Milky Spore does not affect pets, beneficial insects, fish, bees, birds, other animals, plants, or man. It is not a poison.

6. Can I mix the Spore with water and spray it?
Neither the Milky Spore powder nor the Milky Spore Spreader mix should be mixed with water and sprayed.

7. Can I cut my grass after applying the Spore?
Do not mow or rake your yard until Milky Spore has been soaked into the soil.

8. What if I treat my yard and my neighbor does not?
Your lawn will be protected even if you are surrounded by untreated property. Eventually, the Spore will creep next door into adjacent areas by natural movement.

9. Won’t beetles fly in from my neighbors yard?
An adult beetle feeds only during it’s first two weeks. By the time they fly in from adjacent areas, any new grubs laid in late Summer will be affected by the Spore.

10. What about Moles?
Eliminating grubs with Milky Spore often cause Moles and Skunks to feed elsewhere. Unfortunately, they may head for your neighbor’s untreated yard instead. Milky Spore does not affect moles, it simply eliminates their food source.

11. Can I have too many grubs?
If you are rapidly losing your lawn due to too many grubs, more than 10 per square foot, you may be wise to use an insecticide along with Milky Spore.

12. How do I know if I have beetle grubs?
Grubs feed on the roots of your grass which can become brown and die. Simply lift the dead grass and look for white larvae curled into the shape of a “C” about the size of a penny. Active grubs can completely destroy a lawn. Use Milky Spore for safe, long-lasting control.

13. Do beetle larvae feed more aggressively in Fall?
Yes, grubs in fall are in the first instar stage and are feeding for growth to store body fat for winter. In the spring, grubs reach 3rd instar prior to molting and do not require as much food.

14. Are grubs infected by Milky Spore in spring when rising to the surface following hibernation?
Grubs become infected by swallowing a spore. They do not become infected by rubbing up against spores or passing through them. Since grubs feed less in Spring, the incidence of infection is not as great as in fall.

15. What are the application rates for Milky Spore?
Milky Spore Powder in cans is a one time application put down in spots in measuring teaspoon amounts every four feet apart creating a checkerboard pattern of spots throughout your yard. Each spot contains 100 million spores.
Milky Spore spreader mix should be applied at least 3 times a year for 2 years. You should apply Milky Spore Spreader Mix with a push spreader or a hand spreader in the Spring, Summer, and Fall for 2 years to create the long term residual.

16. Can I broadcast the Spreader mix?
No, Milky Spore Spreader Mix is too light to be used with a broadcast spreader. It must be placed in concentrated areas on the lawn and that is why it must be used with a drop spreader.

17. Can I wait to water in the Spore?
Yes, you can wait 36 to 48 hours before watering in the Spore. Make sure you water the Spore before raking or mowing your lawn. The whole idea is to soak the Spore into the soil where it will become available to grubs feeding on the roots of grass. Simply use an oscillating hose sprayer for 15 to 20 minutes over the entire treated area. There may still be some white residue but this is chalk used as carrier for the spores.

18. What is the difference between the Spreader mix and the powder?
The main difference is that in using the six part spreader mix program you are essentially spreading the spore over an entire lawn rather than in concentrated areas. In doing this the number of spores in any one location is significantly less than the concentrated spot method.
Grubs become infected by swallowing a spore and this occurs by happenstance when feeding on grass roots. The more spores in a given area, the greater chance for infection. Each infected grub dies and releases 3 billion new spores into the soil.

19. How do I know if I have Japanese Beetle Grubs?
St. Gabriel Laboratories provides a free grub analysis for it’s customers. Simply place six grubs in a non-crushable container with some moist earth and grass roots. Don’t punch any holes in the container as grubs do not need much air. Send the container to: Free Grub Identification Program St. Gabriel Laboratories 14044 Litchfield Drive Orange, Virginia 22960 Tel: (880) 801-0061

20. What is the shelf life of Milky Spore?
The older the Spore, the more effective it becomes.

21. What if I get Milky Spore in my eyes? What if I breathe it in?
Milky Spore itself is not toxic. However, Milky Spore contains chalk and a powder carrier. Care should be taken not to get any dust in one's eyes as it is an irritant.

    We had a major problem with raccoons digging up our yard looking for grubs. I've completed the third application and even now the digging has stopped. Of course will finish the fourth application, but this stuff really works. I'm actually going to buy plants now since I believe the raccoons will leave them alone.

  • 4 of 5 Stars  Opinion to be determined
    By Carolyn in COLLINSVILLE on April 23, 2015
    Verified Purchase

    I really can't rate this yet because it's a product that says to apply 3 times per year for 2 years. However, I gave it a 4 star rating because I bought the product on a grub control (thus moles in the yard) recommendation from a friend. They had great success with it. I applied it about 3 weeks ago and so far, have not felt any more mole tunnels and the ones I did have seem to be not as soft. I think this summer will tell more than I can now. I'll apply again in July and October. I will give DoMyOwnPestControl.com 5 stars. The shipping was extremely fast. Had no trouble ordering, paying, etc.

  • 4 of 5 Stars  Mole Deterrent
    By Glenn in Aptos, CA on April 7, 2015
    Verified Purchase

    I'm only giving a 4 star right now because I'm in my first full year of seeing what this product will do. So far, so good. However, I live in a rural area and have a LOT of active mole's. Mainly from April thru July. I had a bad case a few years ago in my lawn and now using the Milky Spore's (after doing research), seems to have deterred a few of the pesky varmits. I do have them in the ditch line and side forest area, but not much in the lawn. I'll return later with an update once I have a few years use. I'm told it can take up to 4 years for the product to really work. For now, ???

  • 5 of 5 Stars  milky spore lawn spreader mix
    By June in Hillsborough, NC on March 5, 2015
    Verified Purchase

    I used this product last year just around the crepe myrtles , golden chain tree, and hazelnut bushes, all of which had been severely attacked by Japanese beetles the previous year. The number of beetles was much reduced as a result. I am hoping one more application will again be effective. I did not apply the milky spore all over my lawn as I did not want to kill the larvae of the fireflies I enjoy watching during July and August.

    5 of 5 Stars  Seems to do the job even when we don't follow the directions
    By Greg in Cobden, IL on October 14, 2014
    Verified Purchase

    I have to begin by saying that we didn't follow the directions. They say to use a drop spreader and apply three times per year but we used a broadcast spreader and applied only in the fall. Nonetheless, we've had a lot fewer mole problems in the areas we used this than elsewhere. Results would probably be even better if we did what they say to do, but we didn't want to spend that much time and money. We do try to minimize our use of pesticides, and this product seems to fit the bill for what we want.

    didn't have any major problems spreading it - i used a broadcast rotary spreader despite the mfg directions saying that it only works with a drop spreader. spread evenly across my yard in May; noticed some grubs in June (don't know if they were specifically japanese beatle grubs though). plan to do another application this July and September, then again next April, July, and September, as per recommended directions to be grub-free for 20 years...

    Verified Purchase

    We have used Milky Spores on our lawn the last 3 seasons. When we first planted a new lawn of tall fescue... the grub worms ate the roots and the yard was full of brown spots in the grass. After applying Milky Spores the end of spring ....no signs of Grub worms any more. Before I could dig up a little of the earth where brown spots were and there would be 40 or 50 grub worms under the grass!!! NO MORE BROWN SPOTS !!!!

QAre Natural Guard products pet and child safe?
I need a product that is for grub control. I need something completely pet safe and child safe. What product do you recommend? Is the Natural Guard grub control product safe? Why are there warnings on the label? Thanks

AEvery pesticide has some level of toxicity, even the natural and organic products. Natural Guard is a "lower risk" product meaning that while there is some amount of toxicity it is very low. Every pesticide, natural or synthetic will have some warnings on the product label as there will be some level of toxicity and safety precautions will need to made.  As long as you follow the product label instructions and keep your children and pets out of the area while the application is being made and until the area is dry you should not have any issues.  As for using a Natural Guard product for grub control, that may not be possible as none of them are labeled for grubs. We do carry Milky Spore which is labeled for grubs and is one of the "lower risk" products. We should have Milky Spore back in stock shortly.

May 19, 2015 Jan from Springfield, Ma. asked:

QWhat is the setting on a Scott's speedy green 3000 for milky spore?

A Milky Spore Spreader Mix is too light to be used with a broadcast/rotary spreader. It must be placed in concentrated areas on the lawn and that is why it must be used with a drop spreader over every square foot of grass.  It requires six applications usually Spring and Fall for three years to build the number of spores in any one area to millions of spores.

QHow much Milky Spore Lawn Spreader Mix should i use for a small raised veg garden?
I have two 4' x4' raised vegetable garden containers. I have grubs in both. I purchased your product. How much should I use on my small area?

A Normally the Milky Spore is applied to a much larger area and to a lawn with a drop spreader so we are unsure exactly how much to tell you to use for your raised beds. One 20lb bag is supposed to cover 7000 sq/ft so if you want to figure out the square footage of your beds and then break down the amount used per 1000 sq/ft that way it would likely be the most accurate application. If you are still unsure, you can contact the manufacturer St Gabriels for a better answer at 1-800-801-0061.
