Homemade Pesticide Recipes

Note: Some recipes online require liquid dish detergent but I recommend you substitute with a gentler liquid soap such as liquid castile or a perfume free, gentle liquid hand soap.

WEBSITE TO CHECK OUT: I also love planting herbs and flowers that NATURALLY repel bad bugs. Click on this GREAT WEBSITE to learn how to use PLANTS as natural pest control!

Many of these recipes below were taken from HERE.


(Misty's favorite) ALL PUPRPOSE PEPPERMINT PESTICIDE SPRAY: great for almost all bad bugs

  • 1/2 tsp of liquid castile soap

  • 10 drops of essential oil PEPPERMINT

  • 2 cups of water. Place all ingredients in water bottle, shake well before application. NOTE: will also repel bee's (which you DON'T want) so do NOT spray on blooms. APPLY LATER IN THE DAY because the oils can actually burn the leaves.

Rhubarb Leaf Mix

1 cup rhubarb leaves 6.5 cups water 1/4 cup liquid castile soap

  • Cover rhubarb leaves with water and bring to a boil. Boil for 20 minutes then remove from heat and cool. Strain then add 1/4 cup liquid soap. Apply. Good for aphids, june beetles, spider mites, thrips.

  • Rhubarb leaves are poisonous, take care when preparing and handling. Do not use on food bearing plants.

Garlic Tea

  • Make your own garlic spray by boiling a pint of water, throw in roughly chopped garlic cloves and steep until the water cools. Remove garlic bits then apply.

Cockroach Killer

  • Mix 1/2 cup flour, 1/2 cup of cocoa, 1 cup Diatomaceous Earth. Sprinkle around baseboards or where you see roaches. If in your home, you can place in a tray or bowl. Roaches will carry it back to their homes and it kills all stages of roaches.

MARIGOLDS: Plant marigolds all around the garden and even between plants to repel many different bad bugs, but they can also attract spider mites and snails.

Garlic, Peppers & Onion Insecticide

Spray on roses, azaleas, vegetables to kill bug infestations. Bury mash in ground where bugs are heaviest. Good for thrips, aphids, grasshoppers, chewing and sucking insects.

Onion Insect Repellent For Plants

Save Onion Peels & Bits To Make Your Own Garden Brew

  • Save onion skins, peels and ends then refrigerate in an empty margarine-sized tub or ziploc bag until the container is full.

  • Once you have enough, place the onion pieces in a pail and fill with warm water. Soak for a few days, up to a week. Optional: You can keep this on the patio in the sun to steep.

  • After one week, strain the onion bits out and store the onion water in spray bottles. Bury the onion bits around plants that are prone to aphids, spiders and other pests.

  • Spray both house and garden plants with the water to fight aphids and pests.

*You could also mix your garlic trimmings in with the onion pieces, bugs hate garlic too.

Mineral Oil Mix

3 parts oil per 100 parts water

  • Benefits: Helps with Aphids, Codling Moth, Leaf Roller, Mealybugs, Scaled Insects, White Fly

Easy Soap Flakes Spray

2 TBS soap flakes (don’t use detergents) dissolved in 1 quart water

  • Benefits: Aphid control


  • Apply the treatment on top of the leaves as well as underneath–don’t overdo it, excess can cause damage.

  • Most recipes can be used effectively with just a weekly treatment. Excessive use may affect the plant as well as kill the good insects you want to encourage in your garden (earthworms, bees, ladybugs, etc.). If you aren’t seeing results with a 7 day treatment, you can bump it up to 5 days but watch carefully to make sure plants can handle it without being damaged.

  • Avoid treating during hot sunny weather, do so later in the day to reduce the risk of burning.

  • If it looks like rain, delay until the weather is clear since any rain will wash away the new application. If it has recently rained, wait till greenery is dry before applying to prevent the mix being diluted with water.

  • When trying a new recipe, test on just a couple leaves first (apply then watch how the test leaves react after two or three days, if no signs of damage proceed with spraying the whole plant).
