If this happens over a large area, such as what was experienced last year in parts of the Midwest, the overall populations can be reduced. Granted, there are still many lawns that are irrigated, so plenty of grubs still made it, but overall, the populations can be reduced by drought. The cooler spring and early summer may have pushed back the adult emergence, which in turn, may affect when the eggs hatch. Keep an eye out for areas of turf that appear to be turning brown when the rest of the lawn looks good.
If so, you may have grubs. No Location Added. Enter your address to find available services. If you don't water regularly, anytime in September should work well, but the earlier the better. Sometimes, skunks and raccoons will flip up chunks of sod looking for grubs. If you catch this in time and lay the sod back down then water it deeply, many times the lawn will recover.
You can apply an organic animal repellent like Nature's Defense, or call in an animal trapper to relocate the pesky critters who are ruining your lawn. I prefer to use the repellent however, because it's difficult to control skunk and raccoon populations in an entire neighborhood. If the lawn is just brown and dead looking, you'll probably need to reseed. The key to successful seeding is seed to soil contact. One labor intensive way to achieve this is to physically remove all the dead grass and haul it to your compost pile, then scrape up the soil with a garden weasel, seed the area, and mulch it with straw, 1 bale per 1, square feet.
To accomplish this, you would cover the dead areas with dirt, distribute seed, and mulch with straw. Turf Type Tall Fescue has a deep root system and seems to be less likely to get damaged by grubs or animal digging. I wouldn't call it grub-proof, but it's a lot more resistant to grubs than shallow rooted grasses like Bentgrass.
If you have a large flat area of grub damage, it might make sense to rent a little machine specifically designed for fixing up lawns. It's a Toro Dingo with a Soil Cultivator attachment. The Soil Cultivator turns dead grass into soil that is ready to seed. It takes a little getting used to, and isn't effective if there are a lot of tree roots, but if you have an open lawn with dead areas, it works great.
Oil from the Neem Tree in India works minor miracles on plants. It coats leaf surfaces and protects them from disease great for roses and acts as a repellent and antifeedant for insects that like to feed on plants. If you apply Neem Oil to your lawn three times a season June, July, and August , the likelihood that you'll have grub damage is reduced. It may also protect the lawn from disease issues.
Milky Spore is another natural alternative for controlling grubs. I'm not a huge fan of Milky Spore for grub control because it only controls Japanese Beetle Grubs, and there are a plethora of other grub species that damage your lawn.
Milky Spore is a good tool if you're trying to reduce the levels of Japanese Beetles in your yard, but not the best product if you're trying to control grubs in your lawn. If you would like our help in controlling your grub populations, or preventing future grub damage, don't hesitate to give us a call. Generally speaking, chemical treatments fall into two categories: curatives and preventives.
