1. Plant Companion Herbs and Flowers

Certain plants emit scents or chemicals that repel pests. Marigolds deter nematodes and aphids, while basil keeps mosquitoes and tomato hornworms away. Pair these with vulnerable crops:

  • Garlic + Roses: Repels aphids.
  • Nasturtiums + Cucumbers: Lure aphids away.
  • Lavender + Squash: Deters squash bugs.

2. Use Neem Oil Spray

A natural insecticide, neem oil disrupts pests’ feeding and reproduction. Mix 2 tsp neem oil, 1 tsp liquid soap, and 1 liter water. Spray weekly, focusing on leaf undersides. Safe for bees but lethal to aphids, mites, and whiteflies.

3. Introduce Beneficial Insects

Encourage ladybugs, lacewings, and praying mantises to patrol your garden. Plant dill, fennel, or yarrow to attract them. Avoid broad-spectrum pesticides, which kill these allies.

4. Mulch with Organic Materials

Straw, wood chips, or grass clippings deter slugs and retain moisture. For extra pest resistance, use cedar mulch—its oils repel ants and moths.

5. Rotate Crops Annually

Pests like cabbage worms and tomato blight thrive when plants grow in the same spot. Shift plant families yearly to break their life cycles.

6. DIY Garlic and Chili Spray

Blend 10 garlic cloves, 2 hot peppers, and 1 liter water. Strain and spray to repel beetles and caterpillars. Reapply after rain.

7. Install Physical Barriers

Use floating row covers to block cabbage moths or copper tape to stop slugs. For birds, try netting over berries.

8. Encourage Birds and Frogs

A birdhouse or small pond invites natural predators. Robins eat grubs, while frogs devour slugs.

9. Handpick Large Pests

For tomato hornworms or Japanese beetles, drop them into soapy water. Best done early morning.

10. Keep Soil Healthy

Compost-enriched soil grows stronger plants resistant to pests. Test pH and amend as needed.
