Aphids are not harmful to humans although they are seen as pests by most people.
Aphids are even edible and some people say they have a sweet or bitter taste.
If you happened to eat an aphid by accident it will not harm you or your animal.
Although aphids may sometimes bite humans which can cause red swelling of the bitten area that should go away within a few hours or less.
The bite from an aphid may leave a very itchy rash which can persist for 2 to 3 days.
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea.
Common names for aphids include greenfly and blackfly, although individuals within a species of aphids can vary widely in color.
The group of aphids includes the fluffy white woolly aphids.
Insecticides and soaps can kill aphids and make them go away.
If insecticides are needed to get rid of the aphids, insecticidal soaps and oils are the best choices for most situations.
Oils that can get rid of aphids include petroleum-based horticultural oils or plant-derived oils such as neem or canola oil.
These products kill the aphids primarily by smothering the aphid, so thorough coverage of infested foliage is required.
A natural way to get rid of aphids in your garden is to make a soap solution.
Mix a few drops of pure castile soap with water in a spray bottle and shake well.
Spray the solution onto your plants, focusing on the areas where aphids are present.
The soap will suffocate the aphids and cause them to die off.
