The short version
Across Memphis, fruit fly control is usually sold as its own small fly service and priced after inspection, not bundled into a general spray. The cost depends on how many breeding sources and drains are involved, whether drain or phorid flies are mixed in, and how many visits the job needs. Humid Memphis summers and late-summer produce make August through October the busiest stretch.
- University of Tennessee Extension notes many companies now sell small fly work as a separate service.
- Fruit flies and drain flies made up 74 percent of small fly calls in a 2022 survey.
- UT puts the fruit fly life cycle at eight to 11 days, so follow-ups matter.
- Drain fly and phorid fly jobs take longer and usually cost more than fruit fly jobs.
- Old, evaporating vinegar traps can start attracting phorid flies, so refresh them often.
This page is for Memphis homeowners and renters with fruit flies that will not leave, people with an existing pest plan who were told small flies cost extra, landlords dealing with a recurring complaint, and owners of restaurants, barbecue joints, bars and markets where sauces, produce and drinks feed flies every day.
What to look for
University of Tennessee Extension describes fruit flies as 2 to 4 mm long, with a life cycle of eight to 11 days depending on temperature. Memphis summers average highs near 91F, which keeps that cycle on its short end for months. UT also lists several Drosophila species in Tennessee, including D. melanogaster, D. repleta and D. hydei, all of which breed in fermenting material. The weather here keeps everything damp. Memphis averages about 70% humidity and around 54 inches of rain a year, so very little dries out quickly. Outdoor garbage, compost and fallen fruit stay wet, and flies breed outside before drifting in. UT notes that fruit fly numbers peak in late summer and early fall, partly because fruit is often infested before it is brought indoors. The job gets more complicated when drain flies or phorid flies are involved, since both develop more slowly and live in drains, grease and decaying matter. Sorting out which flies you have, and where each is breeding, is what you are really paying for.

Why it’s worth acting soon
- With an eight to 11 day cycle, every week of delay adds a generation and more breeding spots.
- Drain flies that settle into pipes take three to four weeks of clean drains to clear.
- In a food business, flies can turn into findings on a state retail food inspection.
- Sauce-covered trash draws flies that then walk across prep surfaces and plates.
- Old traps left out too long can start breeding phorid flies, adding a second problem.

Treatment options and typical costs
Small fly inspection and identification
Quoted after inspection
A dedicated small fly visit where the provider identifies each fly type present, then searches produce, trash, recycling, drains and disposals. Across Memphis, outdoor garbage areas belong on the list because rain keeps them wet. Ask for the species and sources in writing, since the rest of the quote depends on them.
- Time
- One visit
- Best for
- Any home or business with small flies
Drain brushing and enzyme treatment
Quoted after inspection
UT Extension recommends a wire brush plus enzymatic or microbial drain cleaners for drain flies, and the same approach clears drain-breeding fruit flies. Expect it to be priced per drain. Because drain flies take three to four weeks to develop, this often needs more than one application.
- Time
- Two or more applications over several weeks
- Best for
- Kitchens, bathrooms and commercial floor drains
Traps and adult cleanup
Quoted after inspection
Traps and a light aerosol reduce adults after sources are removed. UT stresses that traps only cut adult numbers and that populations will not drop until the larval food source is gone. Vinegar traps also need refreshing, since aged traps can attract phorid flies.
- Time
- Traps maintained for two to three weeks
- Best for
- Finishing a job after sources are cleared
Recurring commercial small fly service
Quoted after inspection
Regular visits that treat drains, service traps and check sauce stations, produce storage and trash. It suits restaurants and bars that create new sources daily. Ask how often the provider comes, which drains are covered, and whether each visit is documented for inspections.
- Time
- Weekly to monthly
- Best for
- Restaurants, barbecue joints, bars and markets

Small flies in the bathroom usually mean a sink, tub or shower drain.Why small fly work is billed as its own service.
University of Tennessee Extension explains why: many companies now sell small fly work as a separate service because it needs dedicated source and drain work rather than a general spray. Demand backs that up. UT cites a 2022 survey of 141 pest management professionals in which small fly jobs increased by 35 percent over the prior year, and fruit flies and drain flies made up 74 percent of small fly calls. For you, that means two things. First, check your plan's terms before assuming fruit flies are included. Second, when you get a small fly quote, look for source inspection, species identification and drain treatment. A small fly service that only adds a spray to your regular visit is not doing the work that ends the problem. If a Memphis provider offers to fold small flies into an existing plan, ask what the extra visits include and how many are covered. If you have a regular pest plan in Memphis, do not assume it covers fruit flies.
Fruit flies, drain flies and phorid flies: three timelines, three price tags.
Fruit flies complete their cycle in eight to 11 days. Once the source is removed, numbers drop within about two weeks. A single visit with a follow-up is often enough. Drain flies take about three to four weeks from egg to adult. Even after drains are brushed and treated with enzyme cleaners, adults can keep showing up for weeks. That often means two or more applications. Phorid flies range from as short as 11 days to as long as four weeks, and they can breed in decaying matter that is hard to reach, including around plumbing leaks. These cases take the most investigation. In a Memphis kitchen with sauces and grease, it is common to have more than one type at once. Ask the provider to identify each one and quote the work for each. A single price for all small flies can hide the fact that the drain work is the long part. The type of small fly you have changes how long the job takes and what it costs, and UT Extension gives clear timelines for each.
Ripe fruit on the counter is the classic source. Refrigerate it once it's ripe.Restaurant and barbecue kitchens: where commercial costs add up.
Sweet sauces, rib bones, produce scraps and drink spills all ferment, and grease in drains can support drain and phorid flies alongside fruit flies. Tennessee's agriculture department inspects more than 9,500 retail food establishments regularly based on risk, with high-risk operations inspected twice a year. A visible fly problem is something any food business wants solved well before an inspector walks in. Commercial quotes usually depend on the number of floor drains, bar sinks and dish areas, how often the provider visits, and what documentation is included. Ask for drain brushing and enzyme treatment on every visit, trap service, and a short sanitation note for staff after each one. Compare plans on what each visit covers rather than the monthly fee alone. A cheaper plan that skips drains often costs more over a summer, because the flies keep coming back between visits. For Memphis restaurants, especially sauce-heavy and barbecue kitchens, fruit fly control is usually an ongoing program rather than a single visit.
A Memphis season planner for small flies.
In winter, lows near 32F slow outdoor breeding. Indoor cases come mostly from a drain, a pantry bin or holiday produce, and they are often quick to clear. By late spring, heat and humidity return. Memphis averages about 70% humidity and around 54 inches of rain a year, so outdoor garbage and compost stay damp and flies build up outside before moving in. June through July, summer highs near 91F shorten the cycle and backyard gardens start producing. August through October is the peak. Market produce, garden harvests and warm kitchens line up. That is when the most fermenting produce sits in Memphis kitchens at once. For cost planning, set traps and refrigerate produce early in August. Businesses should arrange small fly service before the peak instead of waiting for a complaint. Fruit fly pressure in Memphis builds through summer and peaks in late summer and early fall, which UT Extension ties to produce that is often infested before it comes indoors.
How to line up two small fly quotes.
A few questions put them on the same footing. Ask each provider what flies they found and how they confirmed them. Ask which sources they identified, indoors and out, and who will clean each one. Ask how many drains are included and whether they will use a brush and enzymatic or microbial cleaner, as UT Extension recommends for drain flies. Ask how many visits are in the price, and what a follow-up costs if flies continue. Then ask whether the work is part of an existing plan or a separate small fly service, since that affects the total. Write the answers side by side. A cheaper quote that skips identification or drains is a gamble, especially if drain flies are present, because they take weeks to clear. A higher quote that covers sources, drains and follow-up may be the better value over a month. Two Memphis small fly quotes can look very different simply because they cover different work.
What affects the price
- Whether small fly work is included in an existing plan or sold separately.
- The mix of flies, since drain and phorid flies take longer than fruit flies.
- How many drains need brushing and enzyme treatment.
- Outdoor garbage and compost areas that stay wet in Memphis rain.
- Number of follow-up visits needed to cover more than one life cycle.
- Commercial kitchens with grease, sauce and many floor drains.

Where do you see the most fruit flies?
When to call for help
Food businesses should call at the first sign of flies near prep areas. If you already have a pest plan, ask whether small flies are covered before booking, because many companies treat them as a separate service. Call sooner if you see fuzzy moth-like flies or hump-backed flies that run on surfaces, since drain and phorid flies need different work. UT's eight to 11 day cycle means two weeks covers at least one full generation, so steady numbers point to a source you have not found. Call after two weeks of cleanup if trap catches are not falling.
What you can do yourself
You can solve many Memphis fruit fly problems on your own. Refrigerate produce as soon as it comes home, since UT notes fruit is often infested before it comes inside. Take out sauce-covered trash promptly, rinse recycling, brush and flush drains, and set a vinegar trap. Change that trap often: UT warns that aged vinegar can attract phorid flies and become a breeding site. Paying for help makes sense when several fly types are present or when drains are involved. Drain flies need weeks of clean drains, and phorid flies can come from decaying matter you can't reach. A provider who identifies the flies on the first visit can save you weeks of treating the wrong problem. For food businesses, scheduled service and records are usually worth the cost.
Fruit Flies in Memphis
Memphis sits at about 337 feet in a humid subtropical climate, and its rainfall, roughly 54 inches a year, is one of the biggest reasons fruit fly control here involves outdoor bins as well as kitchens. Winter lows near 32F slow outdoor breeding in the cold months, but warm kitchens keep indoor flies going. The city of about 621,000 is known for blues, barbecue and Graceland, and its food scene adds a steady supply of sweet sauces, rib bones, produce and drink spills to restaurant trash and drains. Those settings can breed fruit flies, drain flies and phorid flies at the same time, which helps explain UT Extension's note that small fly work is now often priced on its own. For households, the median home value of about $170,000 does not set the price. The number of sources and drains does, and a short, focused visit is usually enough.

Fruit Flies in Memphis, TN: what the public record shows
Before you compare quotes, it helps to know which fruit flies actually live in Tennessee, when they are busiest around Memphis, and what the state figures look like. Everything below links to the agency or university page it came from.
When fruit flies are busiest around Memphis
University of Tennessee Extension states that fruit fly populations tend to be the greatest in late summer and early fall, as they often infest fruits before they are moved indoors.
UT Extension (publication W 1256) warns that vinegar traps must be checked and refreshed often: as the vinegar ages and evaporates, the volatiles can attract phorid flies and the damp media becomes ideal for phorid larvae, essentially trading one pest for another. It also stresses that traps only reduce adults and that populations will not drop until the larval food source is eliminated, and recommends a wire brush plus enzymatic or microbial drain cleaners for drain flies.

Simple ways to keep fruit flies away
- Refrigerate market produce the day you buy it, since it may already carry eggs.
- Scrape and bag sauce-covered plates and bones, and take the trash out that night.
- Keep outdoor garbage cans lidded so the Memphis rain does not pool inside.
- Brush and flush kitchen and bathroom drains weekly from August through October.
- Replace vinegar traps every few days instead of letting them dry out.
- Rinse cans and bottles before they go into recycling.
- Pull the curtains in the evening so a bright kitchen does not lure outdoor flies against the screens.

Questions people ask
How much does fruit fly control cost in Memphis?
Memphis small fly jobs are priced one at a time after a walkthrough, which is why no set local figure exists. A one-source kitchen job is the lowest case. Multiple fly types, drains, outdoor garbage areas, follow-ups and commercial kitchens raise the total. Ask whether it is billed as separate small fly service.
Why is small fly work not included in my regular pest plan?
University of Tennessee Extension notes that many companies now sell small fly work as a separate service, because it depends on finding sources and treating drains rather than spraying. Check your Memphis plan's terms, and ask what the add-on covers before you agree.
Are small fly problems becoming more common?
Pest professionals report they are. In a 2022 survey of 141 pest management professionals cited by UT Extension, small fly jobs rose 35 percent in a year, and fruit flies and drain flies accounted for 74 percent of small fly calls. Busy seasons can mean longer waits.
Why do drain fly jobs take longer than fruit fly jobs?
UT Extension says drain flies take about three to four weeks to go from egg to adult, compared with eight to 11 days for fruit flies. That means adults keep appearing for weeks even after drains are cleaned, and the job often needs more than one visit.
Can a vinegar trap make things worse?
It can if it is left too long. UT Extension warns that as vinegar ages and evaporates, it can attract phorid flies and the damp residue can become a breeding site for their larvae. Empty and refresh traps every few days. Pair traps with source cleanup, never use them alone.
When are fruit flies worst in Memphis?
Late summer and early fall. UT notes fruit fly numbers peak then, partly because produce is often infested before it is brought inside. Across Memphis, humid weather and summer highs near 91F add to the pressure, so August through October is the busiest stretch.
What should a Memphis restaurant ask a provider?
Ask which fly types they found, which drains and stations are covered, how often they visit, and whether each visit is documented. Barbecue and sauce-heavy kitchens should also ask about grease-laden drains, which can support drain and phorid flies alongside fruit flies.
