Which type of lawn insect killer should you choose?

There are typically two types of lawn insect killers in the market. These are the sprayed and the granular insecticides. And both are used in different settings. Below are several factors that should be considered in deciding which one is best for your use. 

The size of the area you will use it on

The size of the area you will use it on is among the most important things you need to consider before buying either liquid or granular insect killers. It boils down to the amount of effort it would take to treat your lawn. If you need to treat smaller areas, it is best to use granular insect killers as it would be easy to apply them to the soil, and you can ensure that you cover the whole area well. On the other side, it is best to use a sprayed insecticide to treat whole lawns as it is easier and more efficient. 

The existing plants in the area

If you want to treat flat areas like your turf, lawns, and backyards, it won’t matter which product you choose as they will work as effectively as their counterpart. However, it is best to use the sprayed insecticides for flowerbeds. This is because sprays will allow you to coat the leaves and stem better and allow the product to do its job more effectively. 

Safety considerations

It should be noted that these products contain chemicals. Some of which can be dangerous for humans and pets. Some are even not suited for use on plants, especially those for human consumption. It is important to read the product’s label first and follow the safety precautions written on it. Although, if you want to be safer. You may consider using products formulated with natural ingredients.


Natural insecticide substitutes

Aside from the insecticides in the market, which mostly contain unsafe chemicals for people, there are also natural substitutes that you can use. Although their effectiveness isn’t as guaranteed compared to the ones listed above.

Clove oil

This has been identified as an effective insect killer that is safer for use around people, animals, and bees than those in the market. This is a completely natural substitute to the usual insecticide and can kill insects shortly after contact. Its effect has also been observed to continue repelling insects hours after application.

Thyme oil

Thyme oil is another type of insecticide made from essential oils that may be a safer alternative than other chemical insecticides. This can also kill a wide variety of insects while still being safer for pets, bees, humans, and other animals.

Oregano Leaves

Oregano leaves have long been used as an effective means of fending off mosquitos, especially in Southeast Asian countries. However, studies on the matter are not common. Regardless, these plants grow fast and can be spread around the homes if you want to try it out.


Tips for effective use of these products

Take weather into consideration

Most of these products are best used on days that are not sunny. This will allow the products to seep into the soil before it evaporates. This is why these need to be used with water, and the heat from the sun won’t give it enough time to reach the insects living deeper underground. However, heavy rainfall should also be avoided, as this won’t allow for the formula to dry and be washed off instead. 

Mow the lawn beforehand

It is necessary to mow the lawn before you start the treatment. This will eliminate spaces for the insects to run to and hide. Also, overgrown grass would put a greater gap between the insecticide and the ground. Mowing the lawn will ensure maximum contact with the product and the target insects, therefore, being a more effective treatment. Also, mowing the grass beforehand will allow for other beneficial insects like ladybugs, bees, and butterflies to not be harmed in the process. 

Keep people and pets away from the area

Several of these products are toxic to humans and pets. This may cause your skin and eye to get irritated on contact. Thus, it is best to stay away from recently treated areas and allow for it to dry before going to these places.
