The 7 Best Organic Pesticides for Safer Gardening

You plant your seeds, water your plants, and take care of weeds. But then one day you walk out to your garden and discover pests devouring your plants! Fortunately, you don’t have to use a toxic pesticide to banish those bugs. Instead, check out these best organic pesticides.

Also, don’t forget, you don’t have to turn to toxic chemicals to keep bugs out of your home. Instead, simply use one of these best eco-friendly and non-toxic bug sprays for your house.

Why Use Organic Pesticides?

We’ve already discussed why you should use organic fertilizers in your garden, but what about organic pesticides?

If you’re trying to grow an organic garden, you obviously want to use an organic pesticide to keep your food safe to eat. However, even if you’re not trying to follow organic guidelines, it’s still very important to choose organic pesticides.

The main benefit of using organic pesticides is that they’re better for the environment. Chemical-based pesticides can have harmful effects on the environment.

They can contaminate soil, kill other animals, and pollute nearby sources of water, including groundwater meant for drinking.

Additionally, pesticides can leech into food and leave behind dangerous residue. Countless studies have linked pesticides to cancer, Alzheimer’s disease, birth defects, ADHD, and damage to the nervous system, reproductive system, and endocrine system.

Just like you don’t want to purchase antibacterial hand soap or hand sanitizer because they leave behind bacteria resistant to antibiotics, you shouldn’t use chemical sprays and pesticides because insects can become resistant to them.

However, since organic pesticides are biologically based instead of artificially created, garden pests are less likely to develop a resistance to them.

Now that you know why you should use an organic pesticide, figure out what type of pest is bothering your garden and then pick out one of these best organic pesticides!

Keep in mind that this powder is very fine. Make sure you wear a face mask and protective goggles when you apply it so it doesn’t irritate your eyes, nose, and throat.
