Using Milky Spore to Kill Japanese Beetle Grubs

For a number of years our neighborhood has been fighting an infestation of Japanese Beetles. Our landlord up to this point has tried almost everything on the market to deal with the problem. This started with the usual poisons. Then the pheromone bags. Those bags work great at attracting Japanese Beetles and they will be killed but not to a point of going away for good. Like many others have said the bags just tend to attract more beetles making the problem worse. Even though many of our neighbors used the bags I don’t think there was a time we had the problem under any type of control.

Of course I liked the bags do to them being more environmentally friendly. Meaning you don’t have poison all over your yard. This helps to keep water supplies, people and animals safe from contact with substances that could harm them. Unfortunately the bags just weren’t going to get the job done. Earlier this year our yard and trees were professionally sprayed to kill the Japanese Beetle infestation. I’m not sure what product was used. I’d venture a guess it was one of the more popular pesticides.

My thoughts kept coming back to giving Milky Spore a try. Price was the original concern as well as where to purchase it. So a little while back I started seriously looking into this. As the picture above shows we finally purchased the product. What interested me right out the box is the amount of warnings and directions. For a product that is suppose to be safe for humans, animals and water supplies the warnings would have you thinking otherwise. From all the reading I’ve done on this subject what I have never seen is actual pictures of the product container with all the instructions etc listed. This article will now solve that problem. Below I will offer several photos that will allow you to read all of these things.

I feel offering these pictures will help educate people further in regards to Japanese Beetles and Milky Spore as an option to combat them. After I had watched a video on the St. Gabriel Organics website in regards to Milky Spore lawn application. I was truly surprised at all the precautions the box stated to take when applying this product to your landscape. Especially since the woman in the video had no eye protection or any dust mask on. These are just two of things stated to use when applying Milky Spore Powder. I’ll embed that video below as well.

Honestly it would be nice when purchasing Milky Spore online if all these precautions were addressed. Because you end up and have to spend extra money on things like goggles, waterproof gloves and the proper rated dust mask if you don’t happen to have them already. So with caution in mind we took a trip to our local hardware store to make these purchases. Since Milky Spore is a bacteria I figured it wouldn’t hurt being overly cautious. I just hadn’t expected or thought I’d have to wear full body protection to apply the product.

Online some opinions stated that Milky Spore should be applied with temperatures ranging in the 60 to 70’s. Last night when we finally put the product down it wasn’t this cool outside. But rain was in the forecast so we wanted to get the Milky Spore applied. If you don’t have rain coming you should lightly water the product into your soil. I had asked that one of our landlords come and help me with getting the Milky Spore where it should be. This was for several reasons. One I figured I would over apply it and two I wanted to talk about the product. Both of us with goggles, dust mask, waterproof gloves, long pants and shirt took turns using the dispenser tube to distribute the product. We didn’t use the bump to the ground method shown in the video. It was more of a tap the top of the tube to allow an amount of the Milky Spore to make contact with the grass.

The method of distribution was far from exact especially when I was using the dispenser tube. But we did our best to follow label instructions. The worst part about the whole process was having to wear all the long clothes with the goggles and dust mask in the heat. It was discussed several times that Milky Spore only kills Japanese Beetle Grubs. Adult Japanese Beetles can still fly over from a neighbors property who haven’t treated their landscaping to combat the Asian Beetle. This is one major downside to using Milky Spore. You can’t use insecticides against the adults because you need them to the lay the eggs for new grubs who will then become infected with the bacterial milky diseases. While your property won’t be contributing to the problem by providing new adults. Other locations in your neighborhood that are untreated could still have you seeing your landscaping attacked by Japanese Beetles. While it is hard to get most people to agree on the same avenue of attack. You will see your best results when everyone in the area makes an effort to deal with the problem.

From the reading I have done there aren’t to many methods for killing adult Japanese Beetles without the use of pesticides. The few methods that have been recommended are either ineffective or time consuming. This is something I need to do further research into. Both of my previous articles offer a large amount of information to help educate homeowners on the different options available to combat Japanese Beetles. As I mentioned above I think the only one that hadn’t been used at our home until now was Milky Spore. I’m hoping the expenditure will show results in the coming year. Keep in mind that we didn’t use all 40 ounces of product. I’m hoping others in our neighborhood might consider using our leftovers. It should also be kept in mind that if you don’t purchase the concentrated Milky Spore you may need to reapply more than once. Honestly I still can’t tell if we purchased the concentrated version. There isn’t anything stating such on the box and online it was hard to decipher what was what. So use caution when purchasing.
