Grab a cup of tea, settle in, and let’s chat about banishing bugs the eco-friendly way! This is our Top 10 homemade pest repellants for your organic garden.

Did you know that the history of pest control dates back to ancient civilizations? In ancient Egypt, around 2500 BC, cats were revered not only for their companionship but also for their pest-control prowess. Egyptians recognized the feline talent for keeping grain stores free from rodents. Fast forward to ancient China, where around 1000 BC, farmers used predatory ants to protect citrus orchards from pests. The concept of utilizing natural predators for pest control has deep roots, and it’s fascinating to see how our ancestors creatively tackled the age-old challenge of keeping their harvests safe and sound.
