Dark-Eyed Fruit Flies
Diet: Fresh fruits and vegetables, such as bananas, grapes, peaches, pineapples, tomatoes; and fermenting liquids, such as beer, cider, vinegar, and wine.
Reproduction: Fruit flies can develop from egg to adult in as little as seven days. Populations can go from zero to unbearable in a few weeks. Dark-eyed fruit flies can breed in new materials as well as organics in an advanced state of decay. The common thread through all of this is the fact the organic matter must remain constantly moist.
Fruit flies are annoying and persistent in food establishments. Without the restaurant or bar management's acceptance of their role and commitment to cleaning operations and repairs, fruit, phorid, and moth fly infestations are typically impossible to resolve. A pest management professional needs to be involved in:
1. Assisting in discovering the breeding sites
2. Educating and selling the client on the importance of their cooperation.
Treatments cannot solve a small fly problem nor can traps. If the breeding sites are not addressed, then the problem will persist. Bacterial products show much promise for long-term resolution of small fly issues, if they are properly utilized. Constant vigilance by the service professional is needed to help point out areas of concern before they become a problem. Staying ahead of the fly's ability to populate quickly is the best strategy.
