I've get Grubs!!!?
Answers: In most areas of the US, we are concern primarily with three white grubs that do most of the trash to our lawns: these are the Japanese Beetle, May/June Bug and the Masked Chafer.
There are two classes of insecticides that you can use to treat grubs. The first class is identified as preventative. These insecticides offer a season-long residual or “preventive” controls of white grubs. They are becoming the preferred direction strategy. Preventative control strategies require insecticide application prior to egg lay or hatch. Timing varies depending on grub species and where on earth you live. In the upper Midwest: May/June beetle; late May to rash June, and Japanese beetle; late June to behind time July. "Season-Long Grub Control" by Bayer Advanced Lawn or "GrubEx" by Scotts are two preventative products available to the homeowners. If you are looking for an immediate solution to your grub problem, after these would not be my recommended solution at this time of the year. They would be a good choice to prevent another grub problem subsequent season.
The second class of insecticides for white grub control are known as curative. The curative approach entail applying a control product when grubs are present, active, and cause measurable damage. These insecticides should be applied when grubs are actively feed in the root zone. However, greater control can be attained if these insecticides are applied to small, childlike grubs – usually in July for May/June beetle, or August for Japanese beetles. Both "24 Hour Grub Killer" by Bayer Sevin products can be applied as a curative control from Mid-May to Early October. If you want to apply something very soon, one of these curative products would be your best option.
Remember that grubs nurture in the root zone. These insecticides must be within that root zone in direct to be effective. Regardless of the insecticide you use, it must be watered into the root zone to complete maximum effectiveness. Apply at least possible 1∕2 inch of irrigation or rainfall on sandy soils, and up to 3∕4 inch on heavier clay soils. Apply water in 24 hours after your application to get the most benefit. For spray formulations, clear up spray off grass plants and into the soil previously the spray dries. Liquid formulations of some products have shown to be more modernized.
Milky spore is effective singular on Japanese Beetles and works best when soils can reach at lowest 70 degrees F. Here is what North Carolina State University Extension have to say something like Milky Spore: "Commercial preparations of the Bacillus popilliae (milky spore disease) offer some slight effect as a soil treatment. These spores infect and kill in cold blood ONLY Japanese beetle grubs... Results of milky spore have be disappointing, however, and generally do not claim the expenditure".
Next season, if you are looking for an organic, biological control alternative, try beneficial nematodes (Heterorhabditis bacteriophora). Beneficial nematodes attack adjectives white grubs and are an effective, colloquial, & safe biological control alternative to pesticides.
Yes, you will enjoy grubs next spring if you do not treat this stumble. Grubs simply move further down into the soil during winter to avoid freezing. Come next spring they will return to the root zone of your grassland to feed until they pupate into adults, mate and lay eggs, possibly contained by your yard again.
