Fruit Flies in Maine: what to know
What to note
Where you see fruit flies, how long it has been going on, and anything you’ve already tried are the most useful details to mention.
A useful next step
Ask about an inspection, what treatment would involve, and whether follow-up visits are included. You don’t need to identify the problem yourself before getting in touch.

Fruit Flies in Maine: what the public record shows
Before you compare quotes, it helps to know which fruit flies actually live in Maine, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.
The genus Drosophila contains more than 1,500 species; the flies are 2 to 3 mm
Genus size and adult length
University of Maine Cooperative Extension's numbers explain why a Maine homeowner cannot rely on one trap or one product recommendation found online for the specific fly in their kitchen.
University of Maine Cooperative ExtensionSpotted wing drosophila has a saw-like ovipositor letting it cut into healthy soft-skinned fruit, unlike common fruit flies that need overripe or rotting fruit
Why spotted wing drosophila is different
Maine gardeners can no longer assume that sound-looking berries are clean; the fly attacks fruit before it spoils.
University of Maine Cooperative ExtensionFemales can deposit up to 500 eggs in the skins of vegetables and fruit; the cycle from egg to adult can be as little as one week under the right conditions, but is normally 9 to 12 days
Egg output and life cycle
Maine's Board of Pesticides Control uses these figures to argue for sanitation first, telling residents to practice integrated pest management and to use pesticides only as a last resort.
Maine Department of Agriculture, Conservation and Forestry, Board of Pesticides ControlWhen fruit flies are busiest in Maine
University of Maine Cooperative Extension's 2026 alert found SWD in damaging numbers in southern Maine berry fields by early July, which it described as relatively early; populations typically do not reach damaging levels until later in the summer, and the fly survives Maine winters rather than being reintroduced each year.
The Maine Department of Agriculture, Conservation and Forestry Board of Pesticides Control describes vinegar flies as nuisance pests of homes, restaurants and grocery stores that pose little threat to people but transmit sour rot bacteria, and it urges residents to practice integrated pest management and use pesticides only as a last resort. For berry growers, University of Maine Cooperative Extension recommends weekly trap checks, harvesting frequently, and chilling harvested fruit to 36 degrees F for at least 12 hours.
