Buyers Guide

Types Of Insecticide

The main point to consider when buying insecticide is the type of pest control that you are planning to use, as using the wrong kind is a common mistake that the average gardener can make. 

If you go into purchasing insecticide with little to no research, you can end up using the wrong kind of insecticide for your plants, your vegetables and your garden, which can do more harm than good. 

It is imperative to ensure that you are using the right product. With this in mind, let’s have a look at the different types of insecticides are available and what they are best used for. 


Standard insecticides are pesticides that have been designed specifically to kill small insects, such as ants, aphids etc. 

Insecticides tend to be applied after the insects have begun to snack on your vegetables. 

Botanical Insecticides

When we refer to botanical insecticides, we are referring to insecticides that feature organic applications, meaning that they are non-toxic to the environment, animals and humans. 

Organic insecticides are the most commonly used kind of insecticide, particularly in our society when preventing environmental damage to the planet is a number one priority (as is preventing damage to humans and animals, of course!).

Herbicides are non-lethal to insects, as they instead kill weeds. It is common for beginner gardeners to accidentally confuse insecticides with herbicides, so make sure to remember the difference between them, as otherwise you could end up accidentally killing your plants or veggies whilst the pesky bugs live to tell the tale!

Neem Oil

Another non-toxic option, neem oil is- as previously mentioned- vegetable oil that is pressed from the fruits and the seed of the neem tee, which is indigenous to the subcontinent of India but has been introduced across various areas of the tropics. 

Neem oil is excellent for pest control in your vegetable garden for a variety of reasons, as it has a range of beneficial properties when it comes to dealing with pests. 

These benefits include being able to disrupt a pests drive to feed, generally repelling the pests and affecting the hormone regulation of the pests, which can slow their drive to procreate whilst also impeding their growth. 


Pesticides are chemicals that are designed specifically to kill, control and repel both diseases in plants- such as bacteria and fungus- as well as bugs. 

Essential Plant Oils

Much like botanical/organic insecticides, insecticides that contain essential plant oils are also an organic and non-toxic choice. 

However, it is important to remember that whilst essential plant oils can act as a good preventative measure against bugs, they aren’t typically known for killing pests once they have begun their attack on your veggies. 

Some of the most popular and effective essential plant oils include citronella, cedar, eucalyptus, lavender and rosemary. 


This kind of insecticide is also a non-toxic and organic one, as it is extracted from the chrysanthemum flower. 

Pyrethrin might be non-toxic, but it is incredibly effective when it comes to killing certain bugs, including aphids, ants, caterpillars, cockroaches, flies, fleas, true bugs and wasps.


These kinds of insecticides are natural mixtures that are only toxic to bugs, and they are incredibly effective when it comes to getting rid of them. 

Spinosad insecticide comes in spray applications- like many of the other insecticides we have discussed- but they can also come in dust forms and granular forms. 

The kinds of bugs that spinosad is most effective against includes fruit flies, spider mites, thrips, ants and mosquitoes. 

This is also an excellent type of insecticide if you need to see quick results, as you will usually witness these results between one and two days. 

Now that you have a thorough understanding of the different kinds of insecticides that are available, you should be able to choose the one that is best suited for you and your vegetable garden.
