You know chili peppers for their fiery flavor—but did you know they can repel insects and rodents too?
That’s right—the same spicy compound that sets your mouth on fire can send pests running for cover.
With just a few simple ingredients from your kitchen, you can make a powerful, non-toxic spray that keeps your home and garden safe—without harmful chemicals.
Let’s break down how capsaicin, the active ingredient in chili peppers, works to eliminate pests—and how to harness it effectively.
🔥 Why Chili Peppers Work Against Pests
The magic lies in capsaicin, the compound that gives peppers their heat:
It irritates insects’ and rodents’ senses—causing discomfort on contact
It masks scent trails and deters pests from nesting or feeding
It’s completely non-toxic to humans and pets in small, external amounts
Different pests, one fiery solution! 🌶️
