Fruit Flies in Michigan: what the public record shows

Before you compare quotes, it helps to know which fruit flies actually live in Michigan, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

Fruit flies, also known as vinegar flies (family Drosophilidae), are very small, about 1/10 inch, and light brown with red eyes; MSU notes flies of all kinds peak in numbers during late summer, and that the fall months are when fruit fly population size is high and bothersome

Adult size and fall peak

Michigan's indoor complaints are a fall event, particularly for anyone with a vegetable garden or backyard orchard bringing produce inside.

Michigan State University Extension

After eggs are laid inside overripe or rotting produce, larvae emerge in a few days and become adults in as little as seven to 10 days; ripe tomatoes on a kitchen table can become a breeding ground in just a few days

Speed from egg to adult indoors

The Michigan garden tomato on the counter is the classic source, and the week-long cycle is why the flies seem to appear out of nowhere.

Michigan State University Extension

MSU recommends covering a suspect drain overnight with a plastic food storage bag and inspecting it the next morning for adults, and offers two traps: a jar with a paper cone pointing down over juice or rotting fruit, and a glass two-thirds full of apple cider vinegar with a drop of dish soap sealed with taut plastic wrap punched with about a dozen toothpick holes

MSU drain test and trap designs

The overnight bag test tells a Michigan homeowner or restaurant operator whether the drain or the fruit bowl is the actual source before anything is bought or sprayed.

When fruit flies are busiest in Michigan

MSU Extension reports fly numbers peak in late summer with fall the worst period for indoor fruit flies, and puts the spotted wing drosophila activity period from early to mid-June through late fall.

Michigan State University Extension states that chemical control alone will not solve an indoor fruit fly problem because the adults you see have already laid eggs, and that efforts should focus on the egg and immature stages by eliminating food sources and cleaning frequently. It specifically advises emptying and drying the kitchen garbage can nightly during a severe outbreak, cleaning up any spilled fruit juice, beer or wine, checking under refrigerators and movable appliances, rinsing cans and bottles before storing them, and sterilizing drains and traps with boiling water.
