Lawn Grubs are a very big enemy for lawns. If you are planting a garden or a flower bed, or just leveling up some winter potholes, and find one white grub or any type of grub; then you know that you will have a potential Lawn Grub issue. Where you find one grub, you will eventually see more and more of them. These insects can cause very serious damage if their population increases.
During the latter part of the summer time, if you notice that your lawn has some brown spots in it, and you know that this section of lawn is getting enough water, then this is a sure sign that you have Lawn Grubs. Grubs feed on the roots of grass, which causes the browning areas. If this is the case, gently pull back the brown layer of grass and dig around with a garden tool. This is an effective way to determine for sure if you have Lawn Grubs.
If the brown sections of sod are in a shaded area, then Lawn Grubs may not be your issue. Grubs do not usually like shaded areas. Another way to tell if you have grubs in your lawn is if you notice animals digging in the grass. Moles, birds, Raccoons, and other small animals feed off these grubs.
You are probably wondering by now where these Lawn Grubs come from. The answer is from a beetle called the Masked Chafer. This beetle is brown in color and you can sometimes notice them flying around at night. Japanese beetles which are black with a dark brown back will also lay eggs in the soil and the larvae, or grubs will eat the grass roots.
The best way to prevent Lawn Grubs is to keep monitoring your lawns brown sections. If you find any sign of the grubs, you can try insecticides such as Halofenozide, or Imidacloprid. Other insecticides which can be used are Diazinon, or Trechlorfox. You should water your lawn before you apply the insecticides, then again after you apply it, to help it sink into the soil. You can also drive to your local lawn and garden center to check what sort of products they carry. Always look in the lower right or left corner to find out what types of bugs the products get rid of. Some people use Seven Dust, as it kills almost all sorts of insects which could be bad for your lawn.
If you have very severe Lawn Grub damage, it may be easier to reseed the area in the spring. If however, you do not want to reseed, your next option would be to rake away the dead debris and water the area; this can be done right before Labor Day.
You can purchase organic Lawn Grub controls, called Nematodes. These Nematodes are very small worms. There proper name is Heterorhabditis Bacteriophora Nematodes. These worms search for grubs and enter its body; once the Nematode enters the grub’s body it releases bacteria into the grub, which causes the grub to die. You should apply these Nematodes in the late afternoon, and use adequate moisture immediately.
These lawn care tips should help you prevent any unwanted Lawn Grubs; as well as detecting if you do actually have a grub problem, or if you simply have issues with lawn browning. Having a great looking lawn will depend on how good you take care of it.
