Spraying plants with natural pesticides

Key steps

Follow these easy steps to make effective natural pesticides:

  1. Identify problem/risk areas in your garden.
  2. Let your citrus fruit or garlic solution sit for up to 24 hours.
  3. Spray affected areas liberally.
  4. Scatter sand and/or coffee around plants to deter ground-crawling bugs.

Keeping unwanted insects away from your home doesn’t mean you have to spray your garden with harsh chemical pesticides. Instead, you can make your own natural insecticide. Whether it’s natural slug control you’re looking for, or a way to get rid of greenfly, we’re here to help you decide what type of homemade insecticide you’d like to try.

In addition to using a homemade pesticide, make your garden as inhospitable to critters as possible. Rake away leaves regularly, and clear mulch, to prevent bugs from thriving in dark and damp environments.

How to make natural pesticides

Pesky pests in the garden can wreak havoc on your shrubs, plants, grass, and patios. But do you want to spray harsh pesticides around, which could harm the environment, animals, and children? Well, you don’t have to. There are plenty of homemade insecticide solutions you can try. Here are three of the best.

Citrus fruit

A number of different citrus fruits make great homemade pesticide solutions, perfect for garden pest control — lemons, oranges and grapefruits all work, for example. There are a number of ways to employ these fruits to get rid of the pests, including:

  • Leave grapefruit halves, flesh removed, face down on the ground. Ants, slugs and other creepy crawlies won’t be able to resist the scent and will find their way in with ease.
  • Boil the peel of an orange and let the solution sit for 24 hours. Add a few drops of liquid soap and pour into a spray bottle. Then: spray away!

Garlic

Garlic has a pungent smell so strong it supposedly gets rid of vampires! Seriously, though, it’s a really good natural insecticide that repels critters and helps you keep them away from your garden greenery and flowers. Here are a couple of ways to make a garlic spray:

  • Blitz two whole garlic bulbs in a blender with a little water to make a puree. Let it sit overnight, before adding a good glug of vegetable oil, a little soap and enough water to fill your bottle. Spray liberally on any affected areas to scare flying insects away.
  • Send the garlic spray into overdrive by adding some onion and a pinch of cayenne pepper to the mix.

Coffee and sand

We’re combining the two here because both are very good options for natural slug control.

  • Scatter some grains of either coffee or sand around potential areas that critters want to get to. 
  • The smell of coffee will keep them away, and the feel of the sand will also deter them from crawling any further. 
  • As an added bonus, both sand and coffee provide nutrients to the soil, too, which can help your plants flourish.

Keeping irritating bugs away from your much-loved garden doesn’t have to mean resorting to harsh chemicals. As you can see, there are plenty of gentle insecticides that don’t risk harming kids, animals or the environment in the same way. Once you’ve tried these homemade pesticide solutions, you’ll be on top of your own critter control, naturally.
