Important Information on Grubs

Grubs are small larvae of a beetle that lives in the ground. It rarely comes out on the surface, feeding on the roots of the grass. It is colored in white or creamy shades with a dark brown head.

Usually, they prefer to curl into the shape of a C letter. Before you buy any of the killers I reviewed, you have to make sure that it is grubs you are dealing with. Here you can find the answers on how to kill grubs, while almost all of the killers I recommend are suitable for multiple insects.
Why grubs are dangerous for your garden?

After we have already discussed what kills grubs, let’s talk about why we have to kill them anyway. I have to say that all experienced gardeners who were unlucky to find grubs on their territory are not particular fans of these insects. Grubs do not spread diseases or bite people.

However, they eat the grass on the lawn. They feed on the roots and can exterminate huge territories. Once they turn into beetles, there will be another problem, as they will crawl up onto the surface, destroying your harvest and breeding.

How to get rid of grubs without poisoning your pets

The most used variant of getting rid of grubs is to spread killers on the land. Since most of them contain active chemicals, it is recommended to work in gloves and glasses. Most of the killers work actively for 24 hours. After that, they can act as a preventive measure, but they are not that harmful to dogs and people. Just don’t forget to irrigate the lawn to prevent the grass from burning down.

If you are worried about your pets that can’t leave the lawn even for a day, pick eco-friendly Milky Spore by St Gabriel Organics I’ve mentioned on the list. It is harmless to other creatures except for small insects.

How to use different grubs treatments


Usually, grub killers are produced in granules or dust. They all are simple to spread and all developers of the killers attach brief instructions. No matter whether the killer is organic or not, these are common rules. Here are a few simple steps you have to memorize on how to treat for grubs:

  • Choose the perfect timing. The middle of spring and the beginning of summer is the most suitable period for applying insecticides. Grubs just awake from the winter, and still did not turn into the beetles;
  • Wear protective gloves and glasses, no matter whether you use chemicals or natural products. They will protect your skin from itching and allergic reaction, and your eyes from irritation;
  • Use a spreader to apply granules. If you have a dust killer, you can use specific dusters. Some bottles are already made for easy applying, like Sevin Ready to Use Dust;
  • Cover all the territory with the product;
  • Don’t irrigate the lawn for 24 hours.

How to prevent grubs in your yard in the future

Preventive measures are considered the most effective against grubs. They protect the lawn from the appearance of new grubs by the extermination of old grubs and beetles. In my top-5 favorite products list, I specifically mentioned universal killers that take care of all the insects, from their grubs and larvae to adult species.

Almost all of them stay active for several months and kill pests that can settle down on the former habitat of grubs you’ve got rid of. To protect your lawn from the new grubs, I recommend re-applying the killer two times a year.

After you killed pests in spring/early summer season, it is important to spread the product on your lawn at the end of July. This way new grubs will not appear from hatches of eggs. Beetles will not have enough time to lay eggs.

The Widespread Questions about Grubs

I have gathered several questions that you may have had. I advise you to get familiar with them before you buy grub killers. You can also check users’ reviews if you have more specific questions for some of the products that will help you with white grubs in home lawns.

How to tell if you have grubs?


  • Check out whether you have these signs of infestation:
  • The grass is getting brown in random spots. Your lawn looks like a jaguar;
  • Birds, skunks, raccoons visit your lawn more often. It looks like they have found a source of food there;
  • The grass feels like a sponge while you are walking on it;
  • The increased amount of beetles near your lawn.

When to treat lawn for grubs?

It is extremely important to find the perfect time when to put down grub killer. That depends on what you want to do. Usually, we notice grubs at the end of spring or at the beginning of summer.

If you are wondering when to apply grub control products, I recommend you act immediately and not to wait for grubs to turn into beetles or there will be more problems. Experienced gardeners spread the remedy in Spring. To make sure that grubs will not appear again, they re-apply the killer in July or August, before adult beetles lay eggs.

Why are grubs dangerous?

Grubs in lawns are not deadly dangerous, as you may wonder. They are not contagious. These small creatures may look ugly, as they are definitely not colorful butterflies, but grubs are not dangerous for people. However, they are harmful to the grass on the lawn. Besides, if you don’t get rid of them in time, these insects quickly turn into beetles and can cause damage to bigger territories.
