One of the main challenges of maintaining an organic garden is choosing which organic pesticide recipes to use. With so many recipes online, it is hard to know which ones will best protect plant health. Here is a list of ten different recipes for sprays and oils that are guaranteed to protect your garden from common pests. These recipes also have all of the organic pesticides benefits gardeners are looking for: they are environmentally friendly, inexpensive, and most are nontoxic.

Garlic Spray
Steep cloves of garlic in hot water like tea. Spray on plants to repel insects.

Hot Pepper Spray
Mix 1 teaspoon cayenne pepper with a pint of water and a teaspoon of dish soap. Use as a spray.

Salt
Dissolve 1 tablespoon of salt in half a gallon of water and spray to repel caterpillars and other insects that eat leaves. Salt also kills slugs.

Beer
Trap slugs by leaving dishes of beer out in the garden. Slugs will be attracted the beer and then drown in it.

Mineral Oil
Half a cup of mineral oil mixed with a gallon of water protects plants from aphids and flies.

Vegetable Oil
Mix 1 part vegetable oil with 30 parts water and a couple drops of dish soap. This is a general-purpose spray.

Diatomaceous Earth
This is another all-purpose natural insecticide. Simply spread diatomaceous earth over the soil around plants that are having bad pest problems.

Eucalyptus Oil
This works very well for flying insects like bees and wasps. Use small amounts of undiluted eucalyptus oil in areas where you have seen a lot of insects.

Tobacco Spray
This one may seem weird, but tobacco has been used as an insecticide for hundreds of years. Steep one cup of tobacco in a gallon of water overnight, then use the strained liquid as a spray. Be careful, because this one is toxic.

Citrus Spray
Steep 1 part lemon peels in 2 parts water (by volume) and use this mixture against flies.

When applying sprays, you must keep weather considerations in mind. Do not apply if it is very hot, as the heat may cause sprays to burn the plants. Also, don’t apply if it is supposed to rain soon, because the rain will wash the spray off of the plants.
