Here are a few household products that actually work well as organic pesticides.
Lemon insecticide: Grated a lemon and add to boiling water. Turn off the heat and allow it to sit overnight before straining the liquid through a coffee filter. Spray on the top and underside of the leaves of the affected plant.
Oil spray: To make, just mix a cup of vegetable oil with a quarter cup of liquid soap. Shake until it turns white in colour. This is a simple but effective spray coats soft body insects in oil. The added soap helps the oil stick to the bugs. To treat your plants: mix one tablespoon of this liquid with four cups of water and reapply every five to seven days.
Epsom salt pesticide: Dissolve one cup of Epsom salts in a large bucket of water. Add to a spray bottle and apply to the affected plants. The salt works by burning the slugs and beetles. Alternatively, sprinkle salt around the base of your plants, reapplying when the salt has dissolved.
Garlic spray: Peel and crush the cloves from five bulbs of garlic and mix them with 2 cups of water. Allow to sit for several hours and add a few drops of dish soap before filtering through a fine strainer. Add the concentrate to a gallon of water. Spray this mix on your plants once or twice a week. To avoid destroying beneficial bugs, only spray the plant parts that are affected.
Rubbing alcohol spray: Rubbing alcohol can be sprayed directly on the entire plant: including the stems, flowers and underside of the lower leaves. Repeat the application once or twice a week.
