If the grubs in your lawn are identified as chafers or any species other than Japanese. The nematodes will give more immediate control while milky spore inoculation is spreading. For a pesticide alternative I recommend growing Kentucky bluegrass or fine fescue, raising the mowing height to the highest setting on the mower, fertilize modestly (1 to 3 lbs active N per year. Milky spore bacteria, Paenibacillus popilliae (formerly known as Bacillus. I have not seen a single university test with positive results. treatment with a fast-acting curative insecticide in September, but expect only. Milky spore in the soil is not harmful to beneficial insects, birds, bees, pets, or people and milky spore, like other bacteria, is highly survivable in drought conditions but suffers in temperatures of Zone 5 and colder. If the infestation is large enough (>10 grubs per square foot), you can use beneficial nematodes and milky spore powder at the same time. The Milky Spore Tube Dispensers are great for treating larger areas with more convenience. Unfortunately, the milky spore product does not appear to work well for grub control. Never apply milky spore when the ground is frozenit will be useless at this time. Within 7–21 days the grub will eventually die and as the grub decomposes, billions of new spores are released into the soil. Spring and summer applications of milky spore are also effective. This ingestion of the spore by the host activates reproduction of the bacteria inside the grub. Resident spores in the soil are swallowed by grubs during their normal pattern of feeding on roots. This is also the optimal time frame for turf inoculation or applications with milky spore to increase milky spore in the soil environment (there are product specific guidelines that should be followed for milky spore application). In August, when the grubs are close to the surface and feeding, they are vulnerable to infestation by milky spore. Read below to learn more about what is milky spore, milky spore treatment, how to apply milky spore powder and other tips for milky spore grub control. When grubs ingest the milky spore bacteria, they die from the infection.

Its actually a bacterial disease, but dont worryits non-toxic to humans. As the weather gets cooler and winter approaches, the grubs go deeper into the soil, and feeding declines as they over-winter. Milky spore, also called milky spore disease, is a naturally occurring organism in the soil. Milky spore is an eco-friendly option for treating lawn grubs. The eggs hatch soon afterwards and in this larval or grub stage, they feed on the roots of grass and other plants. During this adult stage, the beetles also mate and the females lay eggs in the soil in late July to early August. The adult Japanese beetles pupate in July (in the Northeast United States) and feed on flowers and leaves of shrubs and garden plants. It is responsible for a disease (commonly called milky spore) of the white grubs of Japanese beetles. popilliae bacteria in milky spore products enters the soil during application. Paenibacillus popilliae (formerly Bacillus popilliae) is a soil-dwelling, Gram-positive, rod-shaped bacterium. Milky spore is a natural, organic product that kills Japanese beetle grubs.
