In this guide, we’ll explore a few effective recipes for natural pest control sprays and a handy companion planting chart you can use to plan your garden.
Keeping pests away from your garden doesn’t have to mean reaching for chemical pesticides. In fact, some of the best pest control organic pesticides are simple, natural, and can be made right in your kitchen. Along with homemade sprays, companion planting — the practice of growing certain plants together to benefit each other — can help you maintain a thriving, healthy garden without harming the environment.
1. DIY Natural Pest Control for Your Garden
Natural sprays work by either repelling pests or disrupting their life cycles. They’re gentle on your plants, safe for pollinators, and better for your soil health.

2. Companion Planting: Nature’s Pest Control
Companion planting is the art of placing plants together so they help each other grow. Some plants release natural chemicals that repel pests, while others attract beneficial insects like ladybugs and bees.
