A lot of new homeowners get very excited when it comes to finally seeing their lawn turn green for the very first time. Unfortunately, not all of these homeowners will be able to enjoy their new lawns simply because some of them will find their turf stunted, thin, or having bald patches without any growth.

Although in some cases, it might be because of the lack of proper maintenance or the lack of fertilizers, there are situations when they are actually caused by grubs. What are grubs? Grubs or lawn grubs are actually white worm-like creatures that can live in the soil. They are the immature forms of beetles.

Since these grubs will eat the roots of the grass as well as any organic matter in the soil, the grass on your lawn will easily die. If you do not want your lawn to look patchy or poorly maintained, you will have to eliminate the grubs properly. Dealing with them however, needs to be timed correctly.

How Do I Know If There Are Grubs?

The first thing you need to do is to try to locate areas in your lawn that has brown or yellow spots without any grass growth. The best way to tell if grubs are indeed the culprit is to try to lift the dead turf from the ground. If the grubs are present, you should be able to easily lift the area and see them below.

The grubs will look like C-shaped worms that have tiny legs near the head. You might be able to see a couple of them underneath the soil. You might also be able to see pupae or small beetles. Another way of telling if grubs are the culprit is if you will notice birds, skunks or raccoons digging on the dead turf.

You can also try to dig the area with a shovel. Grubs are typically seen from August to October depending on your area. They will usually feed for 10 days and they will turn into a pupae and become mature by the end of October. Grubs can be European chafers, Asiatic or Japanese beetles.

Why Should I Know When To Apply?

Knowing when to apply the grubex is very important simply because this product will only work against specific growth cycles of the beetle. In most cases, this product will not be able to work properly against mature beetles. This is why you might want to make sure that you will be able to use it earlier.

Most experts recommend that you target the larval stages of the insect so that you will be able to get the correct results. This means that you will have to use the product while the mature beetle is laying its eggs. This will allow the grubs to die as soon as they become hatchlings, ending the beetle’s life cycle.

When To Apply Grubex?

In most cases, experts want homeowners to apply grubex in early spring and in early summer. This will allow you to hit the beetles the hardest simply because this is the time that they lay their eggs. If you do this properly, grubex can easily act on the newly hatched eggs since it will kill the emerging larvae.

With that in mind, you cannot actually use grubex whenever you want to. You should know that you cannot kill the grubs if you put the grubex in too early or too late. You should also remember that beetles lay eggs in the summer and the grubs will start to hatch and eat grass roots by mid-summer.
