10 BEST Insecticides for your Vegetable Garden (2020)

Do you have insects and pests, but don’t know how to get rid of them?

Have pests ever killed your plants leaving you frustrated and wanting to quit gardening because nothing ever seems to work?

After much research, trial and error, and talking to experts across the world I have found the perfect solution for YOU!

Below are 10 BEST Insecticides for your Vegetable Garden!

Not only this, but I am providing the different types of pest controls, DIY organic options, and tips for application.


Types of Pest Control

One of the biggest mistakes your average gardener makes when trying to kill pests is purchasing pest control or insecticide without the proper research.

With little or no research, the average gardener ends up purchasing the wrong insecticide for their actual garden and plants.

Because of this, I have compiled a list of different types of insecticides that can be used for your vegetable garden

Insecticides

Insecticides are pesticides used to kill specific insects like ants, snails, wasps, etc. They are typically applied after insects have begun attacking your vegetable garden

Pesticides

Pesticides are chemicals used to control, repel, and kill insects and diseases, such as snails, slugs, fungus, and bacteria. Typically, all the different insecticides on this list are considered pesticides

Herbicides

Herbicides don’t kill insects. They kill weeds. I am putting it on this list though because gardeners commonly mistake herbicides for insecticides, only to be disappointed with the results.

Botanical (Organic)

Botanical insecticides are organic applications that are non-toxic to humans and the environment. As the years have gone by this tends to be a choice for more and more gardeners.

Some examples of store-bought botanical insecticides are spinosad, pyrethrin, and neem oil.

Spinosad

Spinosad insecticides are natural mixtures that are highly toxic to insects, but to nothing else.

This type of insecticide is great for killing thrips, spider mites, mosquitoes, ants, and fruit flies. It typically comes in granular, dust, and spray applications.

In addition, you can typically see immediate results within one to two days.

Pyrethrin

Pyrethrin is an insecticide that is extracted from flowers and is non-toxic to your vegetable garden. It is very effective in killing ants, cockroaches, fleas, true bugs, aphids, caterpillars, flies, and wasps.

In addition, this insecticide quickly disappears from plants and soils after it eliminates pests within a few days.

Neem Oil

Neem oil is another great non-toxic option that has been extra from fruit and seeds. It should be applied before pests have attacked your vegetable garden. This is a great option for controlling both pests and plant disease.

Essential Plant Oil

Essential Plant Oils are the most non-toxic insecticide option on the list. Some examples include cedar, lavender, eucalyptus, citronella, and rosemary.

It should be noted that these are good preventive options, but do not typically kill pests once they attack your vegetable garden.

Bonus – DIY BEST Insecticide Options

While I personally use and recommend the above insecticides for your vegetable gardens for the best results, I also understand that certain readers may want to create their own organic ones.

For those wishing to DIY their own insecticide, I am listing the 5 best options below. While each of these takes a little bit of work, they are worth the effort.

It should be noted though that these are not as effective or lasting as products you can buy in the stores.

Soap Spray

  • To make soap spray you will want to add 1.5 teaspoons of mild dish soap to 1 quart of water. After mixing you can apply it directly to your plants.
  • This mixture will work against mites, aphids, whiteflies, and beetles

Vegetable Spray

  • To make the vegetable spray you will want to add 1 cup of vegetable oil, one tablespoon of dish soap, and 1 quart of water together. After mixing, you can apply it directly to your plants.
  • This mixture will work against mites, thrips, and aphids

Garlic Spray

  • To make garlic spray you will want to take 2 garlic bulbs and puree them. After pureeing the bulbs add it to 1 quart of water, 1 teaspoon of liquid soap, and add 1/2 cup of vegetable oil.
  • This will work against mites, thrips, aphids, beetles, wasps, and ants

Chile Spray

  • To make chile spray you will want to take 2 chile peppers and puree them. After pureeing them add it to 1 quart of water, 1 teaspoon of liquid soap, and add 1/2 cup of vegetable oil.

  • This mixture works against mites, thrips, and aphids.


10 BEST Tips to Do Before Applying the BEST Insecticide

Typically, you can immediately apply your insecticide after you purchase it. If you want the best results though there are several things you should do before application.

Below, are the 10 BEST Tips to Do Before Applying Insecticide:

  1. Remove infected or weak plants. These plants can quickly spread their disease to other plants.
  2. Use organic soil, fertilizer, and compost. If you use potting mix, change it out every year. Fresh, organic soil typically limit the spread of pests and disease
  3. Rotate crops. One of the easiest ways to limit the risk of pests is to move where you plant your vegetables every year
  4. Use raised garden beds. And keep them close to your house. This again protects them against the elements like insects
  5. Remove debris. Any high grass, dead plants, and other debris is a breeding ground for insects
  6. Mulch. This is a simple one. Mulch around your vegetable garden to prevent a habitat that can encourage insects
  7. Clean your pruning tools. Again, another easy tip. Cleaning pruning tools help prevents the spread of insect diseases.
  8. Always wash your hands and clean your clothes. Again, insect disease can quickly spread from your hands and clothes to your vegetable garden
  9. Wear gloves, pants, and long-sleeve shirts. This will prevent any harm from agitating your skin
  10. Read the instructions. Most people never read instructions and hence never properly use their insecticide


5 BEST Insecticide Application Tips

Just like there are tips to have success before you apply your insecticide there are also several tips you should do during your application to have better results.

Below, are the 5 BEST Insecticide tips I personally use to have the best success.

  1. Buy and use a Chapin Sprayer. This will be the best $15 you ever spend. Easy to use, disperse more spray, and makes spraying much quicker.
  2. Apply your insecticide to a specific area. Many gardeners apply their insecticide to a large area, but the more specific and concentrated the better.
  3. Don’t apply to pets, food, etc. I know this may seem obvious, but gardeners still do it.
  4. Don’t burn wood for a month after application. Burning wood that has insecticide on it can quickly spread into the air and be harmful to you and the environment
  5. Apply at least 24 hours before a rain if you want to have the best results.


Conclusion

After reading this article you should not only have a great idea of the best insecticide killers, but also the best tips to do before application and during application.

In my opinion, I personally would recommend using Insecticide #10, Bayer Suspend Insecticide.

While this is the most expensive option, it is also the most effective against most insects. And while the price tag may make you take pause the amount of mixture that it makes will last you a lifetime!

In addition, I would take advantage of tips 1, 3, and 7 for things you should do before application.

Rotating crops, cleaning pruners, and removing infected plants is easy, cost-effective, and one of the most effective ways to control pests.

I also recommend using Tip #1 and 5 during your application of the insecticide for the best results.

Using a reliable sprayer and spraying before rain can not only save you time and money but will also give you the longest-lasting results.
