Our lawns and yards are little oases of green. We take pleasure in the vibrant green color and the soft, springy turf: a place to relax, a place for our children to play, and something good to look at.

But what if your lawn looks thin with ugly brown spots, patches of grass that look as if they are dying, wilting blades and parts that are just dead?

Pests have invaded your space!

What are granules?

Insecticide granules consist of a porous organic material, like corn cob or clay, with insecticide attached. To activate the insect granules, they have to be wetted – and once wet, the granules release some of the insecticides. This means that the product continues to be active for a relatively long time.

Insecticide granules or spray?

Your first decision – but which suits you best?

Insect killer granules are usually used out of doors in your yard or on your lawn. They are easy to apply since they are packaged ready to use – there is no mixing required.

You are unlikely to accidentally inhale any of the poison, which is always a risk when using sprays – and once watered, the insecticide is activated and seeps down into your lawn. Once there, the granular insecticide gets to work and acts as a very effective lawn insect killer. Providing you use gloves, you are unlikely to either inhale the insecticide or come into direct contact with it. The granules also store well.

Liquid insecticides usually come as a concentrate that you have to mix with water. Then most of the liquid insect killers are applied with a spray. 

A downside to sprays is that they can be blown by the wind and drift into places you do not want to treat. The concentrates pose a certain risk to you when mixing: accidentally inhaling tiny particles or coming into contact with them, which can damage your skin. BUT, they are easy to apply – and some do come ready to use.

In both cases, correct application and reading the instructions and keeping to them will allow the insecticides to work as they should and keep you, your children, and your pets safer.

You need the right tools for the job. For the liquids, you need a sprayer, and for the granular insecticide, a broadcast spreader is the best way to apply the granules – you just need to set it to the correct reading.

What to consider when choosing your granular insecticide

There are a few things you might want to check out when choosing your best granular insecticide:

  • Safety
  • Location
  • Target insect 
  • The time it acts and lasts
  • Ease of application
  • Environmental and ecological issues

So, let’s look at them in a bit more detail.

Safety

There is no completely safe insecticide! Any chemical has risks, and even the organic pest control granules are not 100% safe, but there are ways to minimize the risks when you use them – just follow the instruction on the pack!

Location

Many people make the mistake of applying the granular insecticide just on individual ant heaps in the lawn – and this is ineffective since either some of the ants relocate or there are already ant colonies forming elsewhere.

It’s best to apply the granules over the whole area – which is easy to do using a seed spreader.

And if you treat your lawn early in the day while the ants are still asleep, you may get the best results.

Target insect

Some insect killer granules work for some pests but are less useful for others. You might have ants in your lawn, or you may need flea and tick granules for the yard, and there are many other insect pests you might need to apply pest control granules for.

How can you tell if you have fleas? They like moisture, and they like to hang onto your pets, but if you want to be sure, try this – don a pair of long white socks and walk through the grass! If little black dots collect on your sock, then you probably have fleas!

As for ticks, they stick to you or your pets after a romp in the grass, and you need to remove them safely since ticks spread Lyme disease (which can be serious). You might like to check out this short video on the right way to remove a tick.

When does the granular insecticide work?

When you use pest control granules, you need to activate them by watering them in (or apply before it rains).

Depending on the pesticide you choose, and the insects you are targeting, the results can take effect within a day and continue for several weeks.

For example, if you are using lawn insect granules to kill off ants, then although each ant who eats the poison is killed off within one to two days, they must return to the nest and share it with others. This process can take several weeks. The larger the colony, the longer it is likely to take.

Ease of application

If you have the correct equipment, granules are very easy to use. You just need a spreader, gloves, and protective clothing.

Ecological and environmental considerations

More and more people are taking ecological and environmental considerations into account when choosing their bug killer granules. Does this insecticide kill worms and pollinating bees? Is it safe to use near water?
