Organic pest control recipes


It’s important to think of your backyard as a mini ecosystem where all the elements need to be balanced. So when you do get an invasion of pests, the predator bugs will deal with them in a few days and keep their numbers down. Some times the best solution is just to sit back and let nature sort itself out.

If that doesn’t work, then you can make your own pest control solutions with these organic recipes:

Chilli soap mix – Aphids
Add a generous handful of hot chilies and a tablespoon of pure soap flakes to a litre of hot water and puree in a blender. Strain the mixture through  a stocking. Spray directly onto the aphids and they will quickly die. Several applications may be necessary for particularly bad infestations.

Coffee spray – Slugs and snails
Dilute one part strong espresso coffee to ten parts water and spray it liberally over the foliage of plants that are being eaten by slugs and snails, and on the soil around their base. When the pests travel across the coffee mixture, they absorb it and quickly die.

Milk spray – Fungal diseases, including powdery mildew
Combine one part organic milk to ten parts water and cover the upper and lower surfaces of the leaves and stems thoroughly. This can be used as a preventative measure during humid conditions which favour mildews.

Vegetable oil soap mix – Mites and scale
Blend 2 cups of vegetable oil with half a cup of pure liquid soap and mix thoroughly. Dilute one tablespoon of the mix with a litre of water and spray over infestations. The pests will suffocate and soon die.

Do you have any tried and true organic pest contol methods?

  1. Thanks, these are all great. Any ideas on natural solutions to vegetable seedlings dying from root rot? They grow happily enough to a few inches tall then suddenly the plant droops, withers & dies. No bugs that I can see. When you pull the plant out the roots are wasted & black, almost like the plant was frozen below the stem…but we are on the Sunshine Coast – no frost here! Meanwhile the plants either side may be perfectly fine, there seems to be no rhyme or reason to the placement of the plants that succumb. All suggestions gratefully accepted, that is very sad!

    1. It depends on what you are trying to grow. Perhaps you are watering them too much for their needs, the soil is too wet or boggy. Is the water draining well in the area?

      Make sure your soil is a good mix of different things. For example, compost can be too nutrient rich so it mixs well with some sand or coir to give it better drainage.

      You may need to leave the area fallow for a while.

      1. The seedlings have been broad beans, peas, celery, beetroot, carrot, tomato….the beds are raised & soil actually quite sandy so good drainage. The best answer I’ve been able to come up with is a bacteria in the soil, in which case you’re right, really the only thing you can do is leave the area fallow…very frustrating when you’re growing from seed!

  2. This is for pineapple root rot, but the advice could still apply.

    “These soil inhabiting fungi are favoured by wet soil. Spores are spread by running water and water splash. …. Do not plant in poorly drained areas. Do not overwater. Plant in raised beds and install drains so that rain water can move away quickly. If the soil is alkaline, take steps to lower the pH.” No chemical controls.
