It will take at least two to three years for the milky spore to build up in the soil before it can even think about effectively controlling Japanese Beetle larva in the soil. But not the way that people seem to think it works. yes, to the best of my knowledge it does work. Bacterial Milky Disease, also known as Milky Spore. They are so supposed to deliver long term results. However, that alone is enough to know that they are imagining these “immediate” results because biological controls don’t deliver immediate results. Those that use them absolutely swear by them and will tell you that they see immediate results. We love biological controls! Don’t we? The only problem is is that they are only so-so effective. spraying doesn’t really do anything to reduce the grub populations, so you are only partially solving the problem. If spraying is what you want to do your local garden supply store will have a spray you can use. Spraying for Japanese Beetles can be effective but spraying can have an adverse effect on bees, butterflies and other beneficial insects.
However, your chickens will absolutely love your for doing this! But we really don’t know what that number is. So depending on when you pick her off your plant you are without a doubt reducing the egg population by some number. Each female will lay 50 to 60 eggs, but she does it in small batches of only 5 or 6 eggs at a time. This is sort of, maybe a little bit effective and in a way you know that for each female you pick you have reduced the egg population in your lawn. You can pick the adult beetles of of your plants and feed them to your chickens. before we get started, you need to know, this isn’t my first rodeo with Japanese Beetles or Japanese Beetle Grubs. These are not just my opinions, I’ve researched this a number of times over the years.īut. Methods of controlling Japanese beetles are as follows.Īlong with each method of control I will share with you my opinion of how effective these controls are. The adults die and process starts all over again. It will not affect wells, ponds or streams. It is not toxic to insects, birds, pets or humans. This bacterium becomes more effective over time and has a life span of 15 years. As time passes, the spores will spread to neighboring lawns. As the grub decomposes billions of new spores will be introduced into the soil from one grub.Īs the spores multiply in your soil, they spread to cover the entire lawn. You apply milky spore to your lawn and water it in so grubs become infected by swallowing a spore when feeding on grass roots. Milky Spore is a bacterium that infects and kills grubs. Milky Spore is one of the products recommended by the Amazon book, Home Improvement Solutions : What Every Homeowner Should Know.
