#MILKY SPORE GRUB CONTROL PLUS#

The Bayer 24 hour Grub Killer Plus is a broad spectrum insecticide that kills beneficials as well as pest insects and not recommended. The other downside is that it only controls Japanese beetle grubs and there are many other types of grubs in Maryland lawns. University research has indicated it performs poorly. We have not recommended milky spore for grub control for many years. See our publication on japanese beetles for more information. This product is more environmentally friendly. Look for a season long grub control that contains the active ingredient Chlorantraniliprole. Grub controls are applied as a preventative (time frame is mid June through August). This product is available at many garden shops under such trade names as Doom ®, Japidemic ®, or Milky Spore. Application at the time of turf installation may result in a more uniform distribution of the spores in the soil. In general, adult egg laying begins in July and root feeding begins in August. When milky spore disease becomes established, it will spread naturally to adjoining, untreated areas. If the grub count exceeds 6-8 per square foot, you may want to consider treating for grubs. Look for grubs in the upper soil surface, you may need to dig with a trowel. The turf can be rolled back from the soil like a rug this is usually in late summer to early fall. Reasons include past history of grubs, if you have a sprinkler system that keeps the soil moist for egg laying, and if we have weather conditions like wet summers and lush lawns while the adult beetles are active in June. Here are some reasons to apply a grub control. Grub control products should only be applied to lawns that have experienced a grub problem and grubs are feeding on turfgrass roots. The application of lawn insecticides to kill grubs is no longer recommended if wildlife is feeding on soil insects. Tamp down raised tunnels with your foot whenever they appear and the ground is not soggy. Activity often stops on its own so in many cases control for moles is not needed. They are more a nuisance in the spring and fall when soil moisture levels are higher and prey are closer to the surface of the soil. Moles feed on a variety of soil invertebrate such as earthworms not just grubs. We only recommend a grub control if grubs are feeding on your turfgrass roots.
