best grub killer

Depending on the time of application, the severity of the infestation, and the closeness of the lawn to water bodies or vegetable patches, you may choose from a variety of grub management options.

The most prevalent kinds are as follows:

1. Insecticides for Cure

Curative pesticides destroy grubs at any stage of their development. They either have carbaryl or trichlorfon in them. This is the option to choose if you want to get rid of a significant quantity of grubs and insects right away. They must be administered in the autumn or early spring to perform properly.

2. Insecticides for Prevention

Imidacloprid, thiamethoxam, and chlorantraniliprole-containing products help limit grub development and proliferation. They work on removing freshly born grubs effectively. For the best results, you should use them around June or July.

3. Insecticides Don’t Work on Grubs

Grubs are not killed by lambda-cyhalothrin, gamma-cyhalothrin, or bifenthrin. They are, however, efficient against other insects such as ants, fleas, and ticks. Because they bond to organic stuff in the soil, they do not seep under the earth to where grubs live.

4. Grub Control Products Made Naturally

Long-term protection against grubs may be achieved using milky spores (bacteria) and nematode-containing biological pest management approaches. They last for many years in the soil. One disadvantage is that they do not give quick relief from your insect issue and need time to show results. For example, milky spores must be administered for two years before they can entirely rid your grass of grubs.


Grubs are detrimental to the health of your lawn. As a result, it is critical that you take steps to destroy them as soon as possible. The application of grub-killing insecticides is one such method.
