If you have a plant that is infested with aphids, here's an easy and non-toxic way to get rid of aphids. Put one ounce of Coke (the soda) in a spray bottle along with eight ounces of water. Spray the plant leaves with the aphids with this spray. Make sure you do this outside since you don't want the coke solution to get one the surfaces of your house. Leave the solution on the plant for a week or so, it will kill all of the aphids. Once the aphids are all dead, take the plant outside or in the bathtub and rinse all of the leaves off.
