Snail and Slug Control

Diatomaceous earth is a powder-like dust made of tiny marine organisms called diatoms. It is effective on soft-bodied insects as well as snails and slugs. Spread it on top of the soil and it will cut and irritate soft-bodied pests while not harming other organisms. Placing shallow dishes of beer around plants will also help trap snails and slugs.

Houseplant Pest Control Recipe #1

Mix 3 tablespoons of liquid detergent into one gallon of water and apply it to houseplants with a spray bottle. It is a safe and natural pesticide that is effective on a large variety of bugs and insects.

Houseplant Pest Control Recipe #2

Mix 1 clove of garlic, one small hot pepper and one quart water in a blender. Pour it into a spray bottle and apply to plants. Putting hot sauce on a cotton ball in a house plant pot will also repel pests.

Cabbage Worms and Spider Mites Mix

For garden pests like cabbage worms and spider mites, mix 2 tablespoons of salt in one gallon of water and use in a sprayer bottle.

General Garden Pest Control

Collect several dead bugs then crush and mix them with water. Strain the mix until it will come out of a spray bottle. This mix is for outside use only.

Spearmint Hot Pepper Horseradish Spray

This is effective on many different kinds of outside bugs and insects and should be an outside spray only.

  • 1/4 cup of hot red peppers
  • 1/2 gallon water
  • 1/4 cup of fresh spearmint
  • 1/4 cup horseradish that includes both root and leaves
  • 1 tablespoons of liquid detergent
  • 1/4 cup green onion tops

Mix the spearmint leaves, horseradish, onion tops and peppers together with enough water to cover everything. Strain the solution then add a half-gallon of water and the detergent. This can be safely sprayed on almost any plant. Store the mixture for a few days in a cool place.

Aphids and Whiteflies

Mix a few drops of dish washing detergent with water and spray on plant leaves. This is extremely effective in controlling many soft-bodied insects like aphids and whiteflies.

Homemade Pesticide for Roses

In your blender make a solution of leaves from a tomato plant, 4 pints of water and a tablespoon of cornstarch. Strain the mix and spray it on roses as a natural pesticide. Keep any unused spray refrigerated.

Natural pesticides can work well for any home gardener and are much safer for you and your family. If you want to control pests naturally instead of chemically, homemade pesticides may be the ideal choice.
