If the trap fills and every bag is empty, the fix is the refrigerator and the trash. If the bag over the kitchen drain holds flies while the trap by the tomatoes stays empty, sterilize that drain with boiling water. Seal a plastic food storage bag over each suspect drain at night and check it in the morning. The most useful thing MSU offers a Sterling Heights homeowner is a test, not a product.
September in Sterling Heights: tomatoes, cider, and a seven-day clock.
Refrigerate tomatoes once ripe, empty and dry the garbage can nightly, and keep a trap on the counter until the cold arrives. With adults appearing in as little as seven to 10 days, each September week produces another generation. Orchard apples and a jug of cider add a second wave when the jug goes into recycling unrinsed. MSU points to ripe tomatoes on a kitchen table as a breeding ground within a few days, and a Sterling Heights garden delivers them by the bowlful in September.
Ripe fruit on the counter is the classic source. Refrigerate it once it's ripe.Michigan fruit from June to late fall, and what rides along.

When to call for help

What you can do yourself
DIY is the right first move in most Sterling Heights homes. During a bad outbreak MSU says to dry the garbage can nightly, wipe up spilled juice, beer or wine, look under movable appliances, and sterilize drains with boiling water. A provider helps when film sits in a drain you cannot brush or a landlord needs a written plan.

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.

Questions people ask
Why are fruit flies worst in Sterling Heights in the fall?
Because that is when the most fermentable food comes inside. MSU calls fall the high, bothersome stretch, and a Sterling Heights kitchen in September can hold garden tomatoes, orchard apples and farm-market fruit at once.
How do I know if the drain or the fruit is the source?
Tape a plastic food storage bag over the suspect drain at bedtime, as MSU suggests, and look inside at breakfast. Flies in the bag mean that drain is breeding. An empty bag plus a busy trap by the fruit bowl points to produce.
What homemade trap does MSU suggest?
MSU describes a jar fitted with a downward paper cone over juice or rotting fruit, and a glass of cider vinegar with a drop of dish soap under tight plastic wrap poked with about a dozen toothpick holes.
Is spotted wing drosophila in Sterling Heights?
It is expected statewide. MSU first detected it in Michigan in fall 2010 and puts its activity from early to mid-June through late fall. Blueberries and cherries are hosts, so farm-market fruit can carry larvae into a Sterling Heights kitchen.
Will the Michigan winter end my fruit fly problem?
Only outdoors. Winter lows near 18F end garden and orchard breeding, but a heated house keeps the cycle running. Flies in January point to a drain, a drip pan, or a spill you have not found.
