APHIDS, MITES, SCALES & OTHER SMALL INSECTS
How can I get rid of aphids and spider mites?
1) For aphids, set out a small yellow dish with soapy water in it (aphids are attracted to the colour yellow). For spider mites, use a daily buttermilk spray. Combine ¼ cup of buttermilk and 2 cups of wheat flour in 2 – ½ gallons of water. Shake thoroughly and spray on your plants.
2) For most small insects, spray your plant with the jet function on your hose (but only if the plant is strong enough!), this will dislodge most of them. If you follow up with a spray of some sort, it acts as a one-two punch.
3) For most small insects, soapy water works as a contact insecticide, simply mix a squirt of soap (preferably biodegradable) in a spray bottle with water, and apply to the affected plants.
4) For aphids: plant nasturtiums; aphids love them and therefore aphid predators (like ladybugs) will always have something to eat. When you use a plant like this, it is called a cash crop or a banker plant.
