Why Natural Pesticides Are the Way to Go
Let’s start by talking about why natural pesticides are so much better than their synthetic counterparts. For one thing, they’re much safer for you, your family, and your pets. Synthetic pesticides are full of chemicals that can be harmful if ingested or inhaled. And if you’ve got little ones running around, that’s a major concern.
But it’s not just about safety – natural pesticides are also better for the environment. Synthetic pesticides can be incredibly harmful to pollinators like bees and butterflies, not to mention the other wildlife in your garden. And when those chemicals seep into the soil or run off into nearby water sources, they can cause even more damage.

To use basil as a pest control option, you can either plant it in your garden or crush its leaves and sprinkle them around your plants. However, be careful not to use too much, as excessive use can harm beneficial insects like bees and ladybugs.
