Dead spots in your yard can be an eye sore for you and can be very frustrating. The top culprits can be grubs or beetle larvae, which can make a home in your grass without you even knowing. The grubs tend to feast on the grass roots while they mature causing a lack of water to the roots. You may treat the grubs with grub killer to prevent them from causing more damage to your yard but you must apply it correctly.
There are certain areas in your lawn that are more susceptible to grub infestations then others. Lawns on the west and south are favorite infesting spots because they get the most sun causing the soil to stay warm. Also excessively watered lawn areas at the beginning of the summer will attract adult beetles to lay eggs. Only apply grub killer to those areas that are affected.
Before you even treat the area, make sure that is the problem. If you see a dead patch, use a shovel to dig up a few Frisbee-size samples of your grass around the bare area. Once you have dug up about 2-inches look for three-quarter inch, C-shaped with white grubs. If infestation is the problem you must treat the area properly. Over the past month we have seen improper grub killer applications, which can cause damage to other areas in your lawn-, it is very important to apply it properly.
