Grub Control

Grub Control is a very important part of lawn care.  Grubs can do a lot of damage quickly if not treated properly and at the right time.  They feed on and around the root system of the lawn.  When they eat the roots the lawn has no way to take up any water... therefore the lawn starts to dye from the lack of water.  Grubs are the babies of beetles.  There are a bunch of beetles that lay eggs which we consider to be grubs when they hatch.  Masked Chafer and Japanese Beetles are the most common  types though  and typically lay their eggs over the summer.  If an insect control is put down before July then it will be present int the soil when the eggs hatch... this is good.  The insect control needs to be there when the eggs hatch so that the damage can be prevented.  If the insect control is not put down  in time then the eggs will hatch and the hungry babies will start feeding on and around the roots and will continue this through the fall.  When this happens the lawn will start to dry out from the lack of water and turn brown.  The lawn can then be lifted up like a carpet because there are no roots holding the grass down  to the soil. This is bad and the lawn now needs a lot more work done to it to get it to be green and grow properly.  Also skunks, raccoons and other critters will come out at night looking for grubs to feed on and enjoy a nice midnight snack.  A homeowner will wake the next day to look at a lawn ripped up and destroyed by grubs and nocturnal critters.  Now the lawn needs fixing which includes a grub killer still, then dirt and overseeding so the lawn is level and grass can grow back in the fall.  It's much easier to prevent the damage by having a grub control or grub killer applied before July such as Merit, Mach 2 or Grub Ex.  It should not be applied too early and those need to be put down before the eggs hatch.  Those products can not be applied after the eggs hatch and they will not kill the grubs if applied after the eggs hatch.  If you do not apply a grub control before July and you find out your lawn has grubs you can  have us apply an insecticide such as Dylox, Imidacloprid, Bayer, Seven, trichlorfon, carbaryl.   Once the  proper insect control is applied it needs to be watered in so that it reaches the grubs.  If you skip this step the grubs will continue to feed on and around the roots and damage the lawn until it's watered in.  It should be watered for about 30 minutes, this will usually take the insecticide down to where the grubs are and then the grubs will die.  

Sometimes a lawn that has too much thatch will prevent the grub control from reaching the grubs, it gets trapped in the thatch later and the grubs will not die.  That's why it's important to core aerate regularly to reduce the thatch amount.  Also having a healthy lawn which naturally reduces the thatch amount is possible and important, it's similar to us keeping our body healthy to that the food we eat can do what it's supposed  to do.  Another natural way to help combat grubs and  their damage is by watering the lawn.  This will not kill the grubs but since the grubs are eating the roots and the lawn is dying from lack of water if we water the lawn the lawn will use this water to hang in there and try to stay green.  But this should not be the only method of control, proper mowing, proper watering, controlling the thatch amount and using an insect control when needed will help keep a lawn looking beautiful.  

There are some natural insect controls that are available.  Some are good and some are simply a nice alternative but they all have their limitations.  Nematodes can be introduced to a lawn and they will find the grubs and kill them from the inside out.  This is a nice natural way to control and kill grubs.  They can be put in a sprayer or in a watering can and poured or sprayed onto the lawn.  They then need to be watered into  the lawn so they can be taken down  to where the grubs are at.  Nematodes are a great environmentally friendly and natural way to control grubs.  But if the soil dries out they can die (similar to if a worm travels onto the road, sidewalk or driveway then it gets too hot and the area and the worm dries out), so it's important to have the lawn mowed on the high  side so the grass shades the soil and also the lawn needs to be watered when needed to keep the soil moist for the nematodes.  Nematodes can also kill flea larvae, weevils, and cutworms.  

Another natural way to control grubs is by using Milky Spore.  Milky Spore needs to be applied properly in the spring, summer, and fall for two years before it will work properly.  So you need to plan ahead to achieve good results.  If you currently have grubs then Milky Spore is not an immediate option for controlling grubs.  When the Milky Spore is applied 3 times per year for 2 years straight there will be living  spores in the soil for up to 10 years.  The grubs will eat the spores and the spores will live inside the grubs and reproduce while inside the grub, eventually killing the grub in about 7-21 days.  

Another option for controlling grubs without a pesticide is the use of Cedar Oil.  Cedar Oil can  be sprayed onto the lawn which then gets worked into the soil and can kill the eggs laid by Japanese Beetles.  The Cedar Oil also repels the adult Japanese Beetles so it can be sprayed on a lawn, on the landscape and around the house.  The Japanese Beetles have nostrils down their backside and they dislike the smell of the Cedar Oil so they will go away which means likely less Japanese Beetles in and around your yard which means less grubs in your lawn.  This can be an expensive option compared to chemicals but it's nice to have these natural options for those that want them.  Cedar Oil can be sprayed onto the lawn or landscape with most any type of sprayer.  It's safe for kids, pets, families and kills and repels many insects such as mosquitoes, fleas, ticks, Japanese Beetles, White Grubs, Army Worms and Mole Crickets plus many more.

What our customers are saying

My yard really suffered this year from the heat and drought.  Pure Prairie Organics came right out, surveyed my yard and brought it back to life!  They even took the time to walk my yard and mark each individual sprinkler head to make sure they were not damaged during the aeration.  Many of my neighbors have been loyal customers for quite some time and now so am I! Very friendly service. A+
