If you have noticed that you have little bugs on the plants in your garden, then you may be seriously considering attacking them with pesticides. However, if you are an organic gardener, this is not an option, and even if you do not mind using pesticides, they can harm other plants in your garden or even make some plants less safe to eat. Before you go the chemical route, consider a natural approach to kill little bugs on plants with a home remedy.
Pull off any yellowing vegetation. Wear your garden gloves. Throw the yellowed or dead leaves away in the garbage bag to ensure that any little bugs or eggs on the infected part of the plant do not get a chance to spread.
Combine the rubbing alcohol and distilled water in the spray bottle. Use a 1-1 ratio, which means if you use a cup of rubbing alcohol, you also need a cup of distilled water. Swirl the liquids to combine them.
Spray the rubbing alcohol solution on the plants. Make sure to hit the tops and bottoms of the leaves as well as the plant's stem. The rubbing alcohol will kill the bugs on contact, but will evaporate before it does any harm to the plant.
Repeat the treatment each day until you no longer see the little bugs on the plant. This may take a week or two.
