The Dangers of Pesticide

There’s nothing like growing your own food in your garden. Everything is healthier and tastes so much better than what you buy at the store.

But then, before you know it, you have caterpillars eating your cucumbers, snails devouring your lettuce, and mites making a mess of your green beans.

Even though pest infestations are frustrating, you shouldn’t reach for those harmful, toxic sprays. The sprays might eliminate the bugs, but they’re also bad for you and the environment.

Pesticides Effect on the Environment

Pesticides sprayed on land can make their way into nearby sources of water. These chemicals can then kill fish and other animals. They can also leech into the groundwater and poison our own drinking water.

When pesticides turn into a gas, they can spread far and wide across the land. This can be harmful to people and wildlife.

Pesticides Effect on Human Health

Not only are pesticides terrible for the environment, but they’re also hazardous to your health. Pesticides are stored in your colon, where they slowly poison your body.

Study after study has linked pesticides to birth defects, ADHD, Alzheimer’s disease, and even cancer. They can also harm the nervous system, the reproductive system, and the endocrine system. They can even pass from mother to fetus during pregnancy.

Plus, even if you wash a piece of fruit before you eat it, you can still consume pesticides that have seeped inside.

1. Natural Insecticide Soap Spray

This natural pesticide soap spray is easy to make and good to have on hand, since it can take care of a variety of common garden pests, such as mites, aphids, white flies, thrips, and mealy bugs.

In a spray bottle, combine:

Shake well to combine the mixture. Spray your plant thoroughly, making sure you get the underside of the leaves as well.

Although you can apply this soap spray as necessary, you should NOT apply it during the hottest and sunniest part of the day since it can burn the leaves of your plant. Instead, apply it in the early morning or evening.

2. Homemade Vegetable Oil Spray

This homemade vegetable oil insecticide works very similar to the soap spray, which means it’s also good for controlling aphids, mites, and thrips.

To make the vegetable oil spray insecticide, combine the following ingredients in a jar:

Cover the jar and shake the ingredients thoroughly to combine. When you’re ready to apply, add two teaspoons of the oil mixture to one quart of water in a spray bottle. Shake thoroughly, and spray directly on the leaves of the affected plants.

3. Homemade Neem Oil Spray

Neem oil is an amazingly powerful natural insecticide that’s extracted from the seeds of the neem tree. It acts as a hormone disruptor to insects that feed on leaves and other plant parts, and it can disrupt the entire life cycle of insects at all stages (egg, larvae, and adult).

Although neem oil is biodegradable and non-toxic to pets, birds, fish, and other wildlife, it’s highly effective against a variety of common garden insect pests, including aphids, whiteflies, spider mites, powdery mildew, black spot, and more.

It’s VERY IMPORTANT to note that neem oil is toxic to bees if they’re directly exposed to it. Therefore, you need to spray it when bees are not active, such as at dusk, and give the oil time to dry.

To use neem oil as an insecticide, you can either buy a bottle that’s already premixed and ready to go, or you can purchase a concentrate and follow the directions on the back to make the mixture yourself.

When you’re ready to use it, simply spray it on the leaves of the affected plant. You can also use neem oil preventatively by spraying the leaves of plants that are often ruined by insects before they’re actually infested.

4. DIY Garlic and Chili Pesticide Spray

Garlic and chili peppers are both known for their strong aroma, which means they can often act as more of a natural insect repellent than an actual insecticide. No matter how they work, they’re good at keeping away smaller pests, like Japanese beetles, borers, leafhoppers, and slugs, as well as larger nuisances, such as rabbits and deer.

In a bowl that has a spout, combine:

Let the ingredients steep overnight, then strain and pour into a spray bottle. This mixture will keep for about 2 weeks. When you’re ready to use, spray it liberally on infested plants.

Warning: Chili peppers are also extremely potent to humans! Make sure you wear gloves when you’re making this mixture, and keep the spray away from your eyes, nose, and mouth when you’re using it in the garden.

5. Diatomaceous Earth

Diatomaceous earth is an abundant natural substance that’s made from a sedimentary rock created by fossilized algae. You can use it around your home in a number of ways, including a natural ant repellent and a natural insecticide in the garden.

Diatomaceous earth doesn’t poison insects like traditional pesticides. Instead, the powdery substance gets stuck on the insects’ body and dehydrates them.

To apply diatomaceous earth, simply use it to dust the ground around your plants to help control snails, slugs, and other crawling insects. Keep in mind that since it’s a powder, you’ll need to reapply after every rain.

6. Natural Antifungal Spray

Fungal diseases, such as powdery mildew, are an especially frustrating garden nuisance to deal with because they can quickly overwhelm your entire plant. What was once a healthy and thriving plant now has leaves covered in patches of white blotches.

Fortunately, this natural antifungal spray can help. To make it, you will need:

Add the baking soda and vegetable oil to one cup of warm water and stir until the powder completely dissolves. Combine this mixture in a spray bottle with the rest of the water.

Before applying the spray, first remove the leaves with the most damage. Then spray the solution on the leaves every few days until the fungus disappears. This mixture works best when it’s made and used immediately.
