Before jumping into the list, let’s have a proper idea of the lawn insecticides. You should know why you need granular insecticides for your lawn or garden.

Types of Lawn Insecticides

Insect killers come in different forms. The most popular ones are Granules and Liquid. Both of these are pretty efficient in killing insects. Granular insecticides possess many benefits over liquid insect killers.

First, let’s learn more about these Insecticides.

Granular Insecticides

As the name suggests, granular insecticides come in granule form. They’re usually attached to porous materials like corn cob or ground-up clay.

To apply granular insecticides, you’ll be requiring a spreader. You also can do it by hand with gloves on. After that, it works slowly but steadily.

Granules get exposed as you water the lawn. So, they keep killing insects in your garden even after a long time.

  • Lasts longer outdoors in every weather.
  • Rain doesn’t wash away the insecticides.
  • Exposes itself more to the soil rather than on grass. Hence, it is safe for pets, children, and the environment.
  • Efficient for every season.
  • It takes time to produce positive results.
  • Some granular insecticides leave a mild odor after applying.

Liquid Insecticides

The second type of insecticide available in the market comes in liquid form. Unlike granules, you’ll have to spray the liquid insect killers on your lawn.

However, it’s easy to apply and works pretty fast. But it may not provide you with long-lasting results. Hence, you’ll need to apply the liquid insecticides often in your garden.

  • Good for killing flying insects.
  • Convenient to use.
  • Produce positive results quickly.
  • Not suited for extreme weather.
  • Rain can wash away the liquid insect killers.
  • Direct contact with the liquid can be harmful.

Difference Between Granular and Liquid Insecticides

You already may have understood the difference between these two insect killers. Still, for your convenience, let us explain it in brief.

The first difference is obviously the form. One comes in granular form, while the other one is liquid.

Granular insecticides spread over the soil. Hence it works best for ground pests. On the other hand, liquid pest killers are more suited for killing flies—especially those who attack the leaves.

If you’re applying in a large area, then you may need to purchase extra tools. A spreader will assist you in applying pesticide granules. Similarly, a sprayer is good for applying liquid insecticides.

Most granular insecticides expose themselves slowly. Usually, regular watering and sunlight help it to work better. In contrast, liquids start working as soon as applied. Comparatively, granules stay active longer than liquids. However, nowadays, granular insecticides also start working immediately.

Lastly, you may need to mix the liquid insect killers with other ingredients before applying. That’s not the case with granular insecticides. They come in their optimum form and are ready to apply after unpacking.

Why Should You Choose Granular Insecticides for Your Lawn?

Granular insecticides have a lot of benefits. That’s why most lawn owners prefer this form of insect killer.

Some of the reasons why you should apply granular insecticides on your lawn are:

  • Granular insecticides are best for areas covered with grass. And most of you do want to have green grass on your lawn.
  • Besides, granules are easy to store for a long time.
  • As the granules work slowly, it’s not harmful to the plants. Still, quite efficient in killing insects.
  • If you have edible plants, you wouldn’t want the fruits to absorb liquid chemicals. Hence, granular insecticides are the solution.

These were some of the common advantages why we recommend lawn owners to use granular insecticides.
