Fruit Flies, most times, is a cleanup problem where professionals are not required. Fruit Flies require a source to reproduce, source being a fruit, vegetable or one of their bi-products. If we get rid of the source/breeding area we solve the problem. E.g.. Old fruit in cupboard, under appliances or furniture, spilled juice or pop, empty beer/wine/ pop cases, dirty garbage containers. If sources are cleaned up and removed most times the problem will be resolved.
