Sooner or later, a gardener is going to have to deal with pests. Indoor gardens are particularly susceptible to pests, because they will find no natural enemies there. The first step to pest control is recognizing the problem, and careful daily inspection can go a long way toward preventing total pest infestation. Most gardeners prefer not to use chemical poisons on their food crops, and use biological pesticides instead. Examples of biological pesticides are Neem oil or pine soap solution. If choosing a store bought pesticide, read the label to ensure it is safe for fruits and vegetables.
