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

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.

    By Karmen in Iowa City on 11/11/2015

    I first put milky spore on my lawn about 3-4 years ago. I haven't had any moles since. Neighbors on both sides of me have moles. I must have missed a small area between my house and one neighbor, and a mole took advantage of that. I've treated and will treat again in the spring. This stuff works 100%. I received my order quickly. Great service.

    By Bobby in Manning, S.C. on 11/03/2015

    Just completed my third application of milky spores on 35,000 square feet of lawn. The lawn looked much more healthy this summer. I hope that one of the advantages of getting rid of the grubs will be getting rid of the moles. Can see some improvement in mole population since the first application.

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.

QCan I put Grub X down now and follow-up with Milky Spore Lawn Spreader Mix in May?
I have a terrible mole/vole/grub problem. Nematode application this past spring did little. Want to try your product next spring (already had a freeze here). Can I try putting down grub x now, follow through with your product Memorial Day, then July 4 and Labor Day? Also how do I put your product in my extensive perennial beds (can't use a spreader there!)? Thanks

A

If you have already had a frost, then it is very unlikely there are still any grubs actively feeding close enough to the surface to be killed by curative insecticides. You should apply Milky Spore Lawn Spreader Mix in the Spring, Summer, and Fall for 2 consecutive years for best results. If there are areas where it is difficult to apply with a spreader, then you can wear gloves and use your hands to disperse the product. Be sure to remove any groundcover such as pine straw, wood chips, etc. so that the spores will actually get into the soil. Be sure to read the FAQs on the product page and the product info sheet for more information.

QWill milky spore control June Bug white grubs here in South Florida
From what I have been told at nurseries we do not have Japanese beetles here in South Florida and the white grubs I am finding in my garden are June Beetle white grubs. Will milky spore control these also?

A

The Milky Spore only affects Japanese Beetle Grubs. A better option for you would be to treat in the beginning of May and in June with a product like Merit to control the grubs during the most activity of them in the soil to get the best results. Fall treatments even in warm climates like Florida will not see full control, typically, as they are feeding less on the lawn and will not consume as much of the Merit to be affected by it. The other option if you want something for what activity you are experiencing now, the only product that will really work to drop the grub population is Dylox. It only lasts in the soil about 24-48 hours but its designed to knock back the numbers in large amounts in that time frame.

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

AMilky 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.

APer St. Gabriel the manufacturer, you can never put too much down. You can switch to the Milky Spore Powder. you want to apply 1 tsp every 4 feet.

QCan I use the Milky Spore Granules in one application then the powder the next application?

AThe Milky Spore Spreader Mix should be applied at least 3 times a year for 2 years. 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 using the powder. 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.

Tank sprayer application behind tractor; 1.5 acre residential.

AMilky spore would be a great product for you! Milky Spore should be applied three times a year for two consecutive years in a row. The best time should be in the spring (May), summer (July) and fall (September). It would be too late in the year to apply this product now. We would recommend waiting until the Spring to apply.
