Indoor Gardening Pests – Natural, Organic Solutions

Indoor gardening pests can come along to upset the apple-cart at any time. It’s important to know how to respond should you start seeing pests. I prefer natural pest control methods to chemicals, so that’s what I’ve put together on this page.

Common Pests

Indoor Gardening Pests - Aphids

The most common indoor garden pests that you will come across are:

  • Aphids
  • Spider mites
  • Mealybugs
  • Whitefly
  • Scale insects
  • Soil insects
  • Thrips

Prevention is better than cure

Companion planting is a good way to keep pests away from your plants. This involves having plants that repel pests near the ones that are vulnerable.

This plant Repels these pests
Garlic Japanese beetles and aphids. You can make a garlic/oil spray to spray on plants to repel pests.
Calendula Several above and below ground pests
Mint Aphids and flea beetles
Lavender Moths

Other Prevention Tips

  • Use clean pots and containers when planting new plants
  • Don’t use old potting soil. Use new soil that is fresh. Don’t soil from an outside garden.
  • When you buy a new plant, isolate it from other plants for a month or so. This gives you time to monitor it before it’s able to infect your other plants.
  • Make sure dry, dead leaves and flowers are removed as soon as you notice them.
  • It’s a good idea to look at your plants often with a magnifying glass to look for anything suspicious. If you see something, treat with a soap-water insecticide immediately.
  • Daily maintenance of your plants is important. Pick bugs off by hand that you see on your plants.
