The Problem With Lawn Grubs
Though many people have the motto live and let live that they apply to their daily lives, this may not be an option when it comes to lawn grubs. Lawn grubs are actually the larvae of various beetles and while a few grubs will not hurt your lawn a large infestation may cause serious damage leaving your lawn looking disease ridden with dead and wilting grass and major brown spots.
How Lawn Grubs Damage You Lawn
Lawn grubs damage your lawn by eating the root of you grass causing the grass to weaken and eventually die. Some types of grubs also tunnel which furthers weakens the grass and can even damage other plants as well. Worse they can bring all sorts of other unwanted pests into your yard. These pest eat the grubs and in doing so further cause damage to your grass by tunneling, or digging for the grubs that live just below the surface of the grass. Moles, raccoons, skunks, and various birds are just a lawn damaging animals that an over population of grubs can invite into your yard. So, how do you know if you have a grub problem and what do you do about it?
Detecting A Lawn Grub Problem
Most people are not even aware they have a grub problem until late summer when their grass begins showing brown spots for no apparent reason. At this stage fighting those grubs is sometimes difficult and often results in having to replant grass in those brown spots of you lawn. Chances are if you have had grub problems in the past you have the problem again as beetles lay their eggs in certain types of soil conditions.
The best way to check for grubs is to find a sunny place in your yard and pull back a small patch of lawn. You can do this by cutting the grass in a patch with a shovel on three sides then lifting the sod. If there is a group of grubs hiding under the grass you have a problem and the only way to solve the problem is by treating your lawn and killing the grubs.
How and When To Treat You Lawn For Grubs
There are several kinds of chemical insecticides you can use to rid your yard of your grub problem. However, keep in mind that chemicals may harm your family, pets, and the environment. The best treatment for lawn grubs is to use organic predatory nematodes, which are a type of worm that survives in the wild and will eventually kill the grubs. Early fall is the best time to treat your lawn for grubs as the grubs are near the lawns surface still feeding. Making sure to follow the directions for the use of the nematode compound will help to ensure you are successful in your war against grubs.
Prevention Is Best
Of course preventing the infestation of the grubs in the first place is always the best course of action and the best way to do that is by caring for your yard properly. Avoid planting plants that are particular favorites of beetles and grubs such as baby breath will help as will keeping your lawn properly mowed. When it comes to watering deep watering periodically is better than daily misting as the grubs like moist soil. When your soil is allowed to become dry between watering it helps to make for an unfriendly environment for the grubs to survive in.
