The nematodes then swim and attack the grubs while swimming in water between the soil particles. Nematodes are microscopic worms that are applied to the soil in a water spray. To summarize, even under ideal conditions, purchasing and using milky spore disease is a serious waste of money and time especially since there are more effective organic/biological methods like Nematodes. The Fourth reason not to use milky spore relates to how Japanese beetle grubs must ingest or eat the milky spore in the soil, not come into contact with, but eat it.
The high soil temperature necessary does not occur in our region and the bacteria can take over 4 to 5 years to build up, under ideal conditions, with a high population of Japanese beetles! Wow! You might want to go buy that lottery ticket today versus buying milky spore. Therefore, if you do not have a large japanese beetle population, one where you would likely see damage- why bother? The third reason not to use milky spore in NH and VT is the fact that soil temperature must be between 60 and 70 degrees for 3 months. The second major issue not to use milky spore is you must have Japanese beetles in your lawn in sufficient numbers to promote the bacterial population enough to expand and spread out in the soil. So now you understand that even if milky spore could work, you would be controlling one grub out of many, not good odds. The first reason not to use milky spore was the design, it was manufactured to control ONLY Japanese beetle grubs- unfortunately there are many more! Other turf damaging grubs in NH & VT include Asiatic beetles, European and masked chafers, June and May beetles and armyworms.
Milky Spore comes in a powder and consists of a bacteria. Milky spore has been around for decades and was the first biological control means for Japanese beetle grubs. According to a 2008 University of New Hampshire publication on Milky Spore disease, there are more reasons NOT to use this product than to use it in your home lawn.
