Milky Spore Powder

Milky Spore Powder is a natural, safe, effective grub control product that can remain in the soil for up to twenty years. This is an OMRI certified organic control of Japanese beetle grub control that is safe to use with other herbicides and insecticides that is safe to use around birds, bees, pets and fish and around pools and ponds. Milky Spore Powder contains Bacillus popillae, a bacterium that kills grubs by multiplying inside the grubs, causing them to die. The spores are then dispersed in nearby soil, which is how the product is able to exist in your soil for so long and even comes with a ten-year guarantee.

Please note: Your Milky Spore will arrive in a clearly labeled box. Inside that box will be a white bag that is flipped inside out that has Milky Spore printed on it. The manufacturer, St Gabriels Lab, is a very environmentally conscious company. They had too many bags for a different product that they produce and instead of throwing them away, they opted instead to flip them inside out and use them for the milky spore. This helps keeps costs down for everyone and keeps the bags from being wasted needlessly.

Use the Lawn & Garden Dispenser Tube to apply Milky Spore Powder.

Product Documents


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 in bags is applied with a drop spreader over every square foot of grass and requires six applications usually Spring and Fall for three years to build the number of spores in any one area to millions of spores.

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.

    4 of 5 stars  Product as advertised, funny packaging
    By Susan in Glenn Dale, Maryland on 10/20/2014

    We received the product, but it was in recycled rose food bags, which really threw me! I called "DoMyOwnPestControl" and their service rep knew all about the recycled packages and reassured me that I had the correct product. The coverage of the product was exactly as advertised. We won't know until next summer if the beetle population is reduced and the moles head out for yards with more grubs.

    Buy this if you want to get rid of your Japanese Beetles. It doesn't harm anything and goes right into your yard. By getting rid of the larvae, you also "mole proof" your yard. Don't by the dispensing container…make up one yourself and you will feel much better!

    5 of 5 stars  Helps to keep moles away!
    By Dale in topeka, ks on 08/28/2015

    I initially spread about 4 feet apart like the label says and it took a while to spread itself. I have some moles again up by the house so I bought some more and spread it in about 3 feet apart or somewhat a little closer to make it work faster, sooner. Even in the garden area's.

QWill milky spore harm earthworms?
I have an edible garden with rich soil, likely due to my vast number of earthworms. I want to get rid of the grubs, but I do not want to harm my earthworms. Can Milky Spore help me with that?

AMilky Spore will only harm Japanese Beetle Grubs and will have no effect on any other insect.

QWith milky spore, it takes 3 to 5 years. Should I use another product in addition to get faster results?

ANo. Do not use any other products for grub control when using milky spore. It does take up to 2 years to see the full effect of the product but it will start working on the grubs right away. When you apply Milky Spore the existing grubs must eat the spores and digest them which in turn will multiply and spread the spores. If you kill off the existing grubs the spore will not have a way to multiply.

QMy lawn is now just dirt and dead grass; does it matter when I apply Milky Spores? Should I still apply it?
I plan on reseeding in the Fall because there is no grass there now is it worth putting Milky Spore down (I am assuming no new eggs will be laid on just dirt.)

AMilky Spore can be applied any time the ground is not frozen. That being said, the spore can only reproduce and spread when grubs eat it. If there are no grubs at the time of application the Milky Spore will not be able to reproduce and move through the property.

QWhat would be the best way to apply Milky Spore Powder, and what amount do I need?
My yard is 80'x500', or 40,000 sf. I have an infestation of Japanese Beetles. What is a checkerboard pattern? When to apply?

A

You will need 4 of the 40 oz boxes of the Milky Spore Powder for a 40,000 sq ft area. You should use the Milky Spore Lawn and Garden Dispenser for the correct application method. You will apply one shake of the dispenser in spots every four feet in rows four feet apart. This is considered a checkerboard pattern.

QWhy can Milky Spore only be sold to certain states?
I know they have restrictions, Why this product.

A

Milky Spore is not for sale to all states because these states do not have Japanese Beetles, the only insect this product will work for. White grubs can be other insects as well and other products are needed. Please refer to our White Grub page for the complete product listings and further information to help identify your pest.

QCan I apply Milky Spore Powder now or wait?

A

For Milky Spore Powder to work, live grubs have to ingest it. For long term treatments, we would recommend using Milky Spore Powder. This is a slower acting product, but it will last about 15-20 years in the soil after one application. It 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. Right now the grubs are not actively feeding and going deeper into the soil.

QCan I also use Merit or Dylox with this?
I have a new lawn only two years old, but already see the grubs and the beetles. I need the best solution, please advise.

A

No, Milky Spore Powder and products such as Dylox 6.2 Granules and Merit Granules should not be used together. They will counteract each other.

For Milky Spore Powder to work, live grubs have to ingest it and Dylox 6.2 Granules and Merit Granules will kill them. For long term treatments, we would recommend using Milky Spore Powder. This is a slower acting product, but it will last about 15-20 years in the soil after one application.

With Merit Granules, it is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.

Dylox 6.2 Granules is only active and kills for 48 hours. Dylox should be watered in for at least 1 to 1.5 hours for best results to ensure the product makes it through the thatch layer to where the grubs are feeding.  Mature grubs usually require at least 2 applications, 3 to 4 days apart.
