However, some insects and worms destroy our vegetable gardens, and we call them pests, and we should aim to keep them out of our garden as far as possible.

Let us discuss how to but before then that these are some of the pests, namely:-

  • Insects
  • Weeds
  • Aphids 
  • Whiteflies 
  • Beetles 
  • Fungi
  • Slugs/snails
  • Nematodes
  • Gophers/moles
  • Garden ants, etc

Pesticides that are not good to use

Certain pesticides in the market may look like they solve the issue with the pests momentarily, but they tend to do more damage than just pest control in the long run. Some of these kinds of pesticides with their disadvantages are-


Some of the insecticides, together with killing the insects that destroy our plants, also kill the good insects that are beneficial for our plants and gardens. Hence it results in adverse effects on the health and proper growth of our plants. Some of such insecticides are namely 

  • Carbamates 
  • Organophosphates 
  • Pyrethroids and
  • Neonicotinoids

Most of these insecticides get into the pollen or nectar parts of the plants because of what they become poisonous for the butterflies and bees that might have landed on them and would have helped in the process of pollination.

But the presence of these toxic insecticides kills these butterflies and bees as well. Adding on to that loss, they are also poisonous for even us humans and other animals or fishes whoever may be going to eat these vegetables and has an adverse effect on our health.


Fungicides may be used as pest control for prevention. But are mostly based on the temperatures and humidity levels. The issue of using fungicides is resistance. 


Herbicides that are used as a pest control mechanism are mostly water-soluble. This means that they dissolve in the water that may accumulate on the ground’s surface or even percolate with the groundwater.

Even though they may not be poisonous for humans or animals, they are still very harmful for consumption when they get mixed with water that may be consumed by either of the two. Also, herbicides make the soil contaminated with them, creating the quality of the ground degraded.

This may hamper the quality of the earth and hence affect your produce in the next season.


These kinds of pesticides have baits that contain the chemical metaldehyde that is very harmful in nature for animals, including your own pets and even aquatic life. 


The chemicals in them work like acute poisons against the pests. They are harmful to other animals like the hawks and foxes and can even be poisonous for children if you have children moving around who may come in contact with them somehow.

Even though many pesticides in the market can be readily available to us and look like they do their job of controlling our pests’ primary issue, but still, these pesticides contain a lot of poisonous chemicals and stuff that, together with helping us get rid of the problems, also creates much more damage to the health of humans, animals, and nature at large.

Here are some pesticides that you can use for vegetable gardening pest control that are organic in nature and help in pest control without the use of poisonous chemicals. Let us discuss the organic pesticides together with the pests that they are suitable to use against-

However, if your garden is heavily infested by such pests and handpicking is not suitable for you anymore, then you can use an organic pesticide using the following-

  • Take a tablespoon of bacillus thuringiensis (Thuricide)
  • And mix it in a gallon of water.

So you can make this mixture and put them in a spray bottle. Make sure the spray bottle is clean every time you use it. Try to use the entire batch in the same go as if you want to store the same mixture for future use; it might not work well the next time. So prepare it when you are willing to actually spray it on your plants. 

The best time to spray this mixture is the morning time or the evening time, and you should avoid using it during the sunlight on your plants. As we know, caterpillars and worms might be present under the leaves as well. So make sure that you spray the mix all over the plants and especially under the leaves. So using this, you can ensure vegetable gardening pest control against worms and caterpillars.

#2- Organic pesticides for insects like Aphids, whiteflies, thrips, mites, and other insects.

Many insects attack our plants and destroy them. In order to control these kinds of insects, we can use the neem oil mix as an organic fertilizer. Neem oil has a chemical called azadirachtin that helps in preventing the growth of such insects naturally and regulates them without causing any damage. For making this mix-

  • Take a tablespoon of neem oil of horticulture grade.
  • And then take a tablespoon of insecticidal soap or horticulture grade, or you can also take a non-dishwashing detergent dish soap, for example, pure Castile liquid soap.
  • And mix them in a gallon of water.

After mixing them well and putting them in a clean spray bottle, they are ready to be used. It is organic and does not create poisonous damage, unlike other pesticides. This mix can be used twice in a week in the season of massive pests and once will be sufficient during the season of moderate to low pests. Try to use up all the mixture as they are not suitable to be stored.

Ensure that you spray this pesticide on the leaves and even under the leaves since many insects stay hidden underneath.

#3- For large insects like beetles, stink bugs, thrips, and other large ones.

Since decades gardeners have used pyrethrin to concentrate as pest control, and it is one of the best ways to grow a healthy pest free crop. For this, you can 

  • Take a teaspoon of pyrethrin concentrate of residential grade. 
  • Mix it up in a gallon of water

These pyrethrins are found in chrysanthemum flowers and are organic and fair to keep the beatles and large insects away. You should use them the same way as told above. 

#4- For leaf fungus

Sometimes the plants can have fungal problems like powdery mildew, leaf spot, leaf dampening, etc. due to different kinds of bacterias and fungal pests. It can affect the seedlings and mature plants, causing lots of damage to them.

For this, you can use potassium bicarbonate, garlic extracts, or liquid copper fungicide that can help you in dealing with harmful bacteria and fungal issues in plants. You can use these components by mixing them in a gallon of water and using them in clean spray bottles. 

Spray on the leaves as well as underneath. You can spray pesticides in the morning or evening but don’t use them during the daytime when there is sunlight as it may damage the plants.

Do not grow the same family of plants at the same spot every year. Keep rotating the plantation areas of the same kinds of plants every year since it gives the diseases a chance to build upon them. The plant families should be turned to a different place with adequate sunlight conditions to grow well.

You should plan your gardening style in such a way that you can get success in having vegetable gardening with reasonable pest control right from the start, and taking care of crop rotation can be a game-changer in that case.

#4 Frequent harvest 

When your plants keep growing and start to mature, it feels great to see the foliage and the vegetable and fruits hanging from the plants. But it is an attraction to our eyes as well for the pests. If you keep your foliage growing and don’t harvest them, there is a chance that different types of pests can attack them and spoil your vegetable garden.

Hence you should keep harvesting as much as you can during the harvest season when the plants are harvested. If you leave them, there can be a pest attack and a danger for your beautiful crops. 

#5 Use sprays

When you notice pests in your vegetable garden, you should do something without delay. If the pests attack is only at its primary level, you can use the sprays mentioned in the article, depending upon the pest attacking your garden.

By using organic pesticides, you can get rid of pests without causing damages. So you must use sprays weekly in your garden if there is a moderate pest attack, or you can use twice in a week if more. 

#6 Water early and take care of sunlight
