Sustainable Pesticides 

Over the past year, the Sustain team has encouraged our readers to connect with plants: 

• Native plants for an eco-friendly yard
• Vegetable and fruit gardens to understand food cycles
• Plants as physical and mental therapy

Living in Florida means you are likely not the only one enjoying those plants.  Today, we are talking about pests and sustainable ways to control them. 

In the United States, we use nearly one (1) billion pounds of pesticide each year.  Most of that comes from the industrial chemical industry.  Those chemicals can contaminate soil, leach into water supplies, and harm wildlife. 

Are there ways to control those pesky visitors without harsh chemicals?   

Start with the Plants 

Before you consider pesticides, think through the physical structure of your plant-space: 

• Are there other plants/vegetables that would be more resilient in your space?
• Could you include other plants in your space that would mitigate pests?

The latter is called “companion planting”.  Certain plants do better with specific friends.  These “companions” may prevent pests, attract beneficial insects, or enhance the surrounding soil.  Marigolds are a great example of this triple-play benefit. 

Then Move into Your Kitchen 

The most common approach to creating a natural pesticide is 1) to combine certain household ingredients with water and then 2) spray the solution on your plants. 

Here is a list of common ingredients that make fantastic pesticides: 

• Vegetable oil
• Soap (we recommend Castille)
• Garlic
• Chili pepper
• Vinegar

This article provides guidance on the quantities and techniques for your spray solutions. 

And Finally Head to the Garden Store 

There are two, natural pesticides that you won’t have lying around the kitchen: 

• Neem Oil
• Diatomaceous Earth

Neem oil is extracted from the Neem tree; the oil is highly effective at all stages of insect development and is non-toxic.  Diatomaceous Earth derives from fossilized algae and is spread across your plants as a powder. 

Quick Tips 

Even “natural” pesticides can be harmful.  Remember the following when using: 

• Wear protective gloves and eye covering
• Be mindful of children and pets who may encounter pesticides
• Spray in the morning or evening (away from direct sunlight)
• Do not use pesticides on stressed plants

Enjoy your green space!
