Chemical sprays aren't the only answer to garden pests. Building a system where beneficial insects do the work is slower but more stable.
Certain plants attract helpful predators. Yarrow and dill bring in ladybugs and parasitic wasps that hunt aphids. Cilantro and fennel draw wasps that target cabbage worms. Alyssum, cosmos, and marigold support lacewings and pirate bugs. These flowers also feed ground beetles and tachinid flies that manage slugs and tomato worms.
The key is leaving room for the whole food chain. If you spray everything, predators starve. Let some pests stay so beneficial insects have a reason to stick around. A diverse garden with mixed plantings gives them shelter and breeding space.
It takes patience. You won't wake up to a pest-free garden overnight. But over time, the balance shifts. Pests still show up, but they're managed by the insects already living there.
