The short version
Fly control in Alabama means finding the breeding source first, because the state's subtropical climate keeps outdoor filth flies cycling nearly year-round. With summer highs around 91F across Alabama cities, a house fly can go from egg to adult in about a week, so sprays alone fail fast. Remove garbage, pet waste, drain biofilm, or a hidden carcass, then handle the adults.
- Statewide climate context cannot identify a property-level source.
- Adult knockdown does not remove larval habitat.
- Commercial programs should document zones, counts, findings, and corrective actions.
- Confirm provider credentials, scope, pricing, and follow-up in writing.
- Research: Local quotes vary; ask for a written estimate.
For Alabama homeowners, renters, landlords, and small-business owners who keep seeing flies indoors and want to stop the cycle rather than repeat it. If you have a slab home with a floor drain problem, a dog run that stays wet, or a few chickens behind the house, the sections below apply directly.
What to look for
The median winter low of 34F slows outdoor breeding but rarely stops it, and indoor drains never slow at all. Alabama's median summer high of 91F sits near the fast end, so a can missed for one pickup can produce a full generation before the next truck. Texas A&M AgriLife Extension puts the house fly at about 45 days from egg to adult at 60F and about 7 days at 95F. Heat sets the pace. Phorid flies breed in wet decaying matter, including soil under a slab where a sewer line has cracked. Drain flies breed in the biofilm inside drains and condensate pans, which in a state with 72% median humidity almost never dry out. House flies, blow flies, and stable flies breed outdoors in garbage, manure, grass clippings, pet waste, and carcasses. Four fly groups cause almost every indoor complaint in Alabama, and they breed in different places.
- 1Repeated adults in the same zone while doors and windows remain closed.
- 2Small flies resting near drains, wet equipment, beverage stations, or mop areas.
- 3Larger flies clustering at windows or emerging suddenly in one part of a building.
- 4Visible larvae or pupae near waste, drains, animal material, or another organic source.
- 5Monitoring counts that remain elevated after adult-only treatment.
Why it’s worth acting soon
- Breeding material can continue producing adults after visible flies are killed.
- Food and sanitation concerns can expand when waste, drains, or moisture are not corrected.
- Repeated pesticide use without source identification can add cost without resolving the cause.
- A plumbing, moisture, or concealed-source problem may worsen while attention stays on adult insects.

Under-sink leaks and forgotten food under cabinets can keep small flies going.A Alabama source-inspection sequence.
Inspect entry routes, waste, animal areas, drains, beverage or food residue, cleaning tools, condensate, and concealed-source clues. Record the affected rooms or zones, approximate counts, time, and fly appearance. Retain a specimen or clear photograph when identification is uncertain.
flies activity by season.
In Alabama, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in. The most useful first step in Alabama is to note where you have seen flies and when they appear, because that timeline is what lets a provider focus on the right area instead of treating the whole property. Scheduling before the busy stretch, rather than after it, tends to mean faster service and a more accurate quote, and a local provider can point out the conditions that matter most in Alabama.
Trash bins are the top source in summer. Keep lids closed and rinse bins every week or two.Small flies near drains and wet areas.
Organic film inside drains, overflows, beverage equipment, mop areas, leaks, and other persistently wet locations can support different small flies. Confirm the developmental site before treating. Physical cleaning and repair address the material; adult treatment alone does not.
Larger flies near waste, doors, or windows.
Trace waste handling, animal material, door and screen conditions, loading activity, and any sudden localized emergence. Window concentrations may show where light-seeking adults collect without proving where they developed.
Commercial monitoring that supports decisions.
Number devices, map zones, record counts by date, document sanitation and structural findings, assign corrective actions, and compare follow-up counts. Device placement should support the plan without increasing entry or contamination risk.
How to compare Alabama providers.
Confirm the company performing the work, applicable credentials, inspection charges, treatment scope, preparation requirements, products, follow-up terms, and written warranty language, if any. Ask what observation supports each recommendation.

Where are flies most concentrated?
When to call for help
A sudden crowd of shiny green flies in one room almost always means a dead animal in the structure, and in a humid attic that needs to come out fast. Tiny humpbacked flies coming up through a slab crack or floor drain point to a sewer leak that needs a professional eye before the plumbing bill grows. Call a fly control company in Alabama when flies keep arriving in a room with no obvious food or trash, when you find maggots somewhere you cannot reach, or when a spray worked for about a week and quit.
What you can do yourself
You can handle a lot of Alabama fly problems yourself when the source is in plain sight. Lid and rinse the outdoor can, get it picked up weekly, and scoop the dog yard every day or two, since at 91F a missed week is a full generation. Scrub bathroom drains with a stiff brush and follow with a bacterial drain cleaner, then check the condensate pan under the air handler. A professional earns their fee when the source is hidden. A carcass behind drywall, a cracked sewer line under a slab, or a crawlspace that has stayed damp through 54 inches of rain all need tools and patience. Do not pay for a perimeter spray with no source named.
Flies in Alabama
The coast is the wettest and warmest end, where garbage and pet waste breed house flies in nearly every month. The northern cities get a slightly longer cool stretch but still see six or more generations a year, since the University of New Hampshire Extension counts six to eight even in New Hampshire. Statewide, 72% humidity and 54 inches of rain keep drains, condensate pans, and crawlspaces wet in every season, and a median home value near $220,000 points to mid-century stock on slabs or crawlspaces with aging sewer lines. Alabama runs from the Tennessee Valley around Huntsville and Decatur down through Birmingham and Tuscaloosa to Montgomery and the Gulf Coast at Mobile, and the fly picture shifts along the way. The whole state is subtropical, with a median summer high of 91F and a median winter low of 34F across the 18 cities in our data, so the outdoor filth fly season is long everywhere.
Fly tips from the experts
Where are the flies coming from?
The kind of fly tells you where to look. Around Alabama, note its size, where it gathers and when it shows up. Then go after the source.
Small flies near drains
Tiny, fuzzy flies near a sink or shower usually breed in the slimy film inside the drain. Scrub the drain with a stiff brush. Spraying the adults won’t stop them.
UC IPM: drain fliesHouse flies around doors and trash
House flies breed in garbage, pet waste and rotting plants. Clear those out first, then add screens and keep doors closed. Traps help, but they don’t fix the source.
EPA: managing fliesWarm weather speeds things up
In warm weather, flies go from egg to adult faster. Take trash out often, rinse bins, and keep screens in good repair. Sprays are a last resort, not a fix.

Simple ways to keep flies away
- Keep waste containers clean, closed, and emptied on a schedule matched to use.
- Physically clean confirmed drain sources and correct contributing leaks or moisture.
- Repair screens, sweeps, and gaps and avoid routinely propping doors open.
- Clean pet and animal waste promptly and store feed securely.
- Dry mops and cleaning tools and correct condensate or standing water.
- Use dated monitoring records to confirm whether corrective actions reduce activity.
Commercial kitchens need a steady routine: floor drains, dumpsters and doors all matter.Did you know?
House fly maggots can hatch within 8 hours of the eggs being laid in warm weather.
A house fly adult lives up to about three weeks.
Blow fly adults emerge one to two weeks after maggots first appear on a carcass.
Questions people ask
What fly problems occur in Alabama?
Several fly groups may occur, but their importance varies by region, season, property, and source. Identification and the sighting pattern are more useful than assuming one statewide problem.
Does Alabama weather identify the source?
No. Weather can affect activity and development, but it does not prove where flies are breeding.
How much does fly control cost?
This site does not publish an invented statewide price. Obtain a written scope and quote from the provider performing the work.
Will spraying visible flies solve the problem?
Adult treatment may reduce visible activity, but it does not remove larval habitat or correct entry.
How should a commercial program be documented?
Use a zone map, numbered monitoring devices, dated counts, findings, assigned corrective actions, and follow-up records.
Does Fly Exterminator perform treatments?
Confirm identity, credentials, service area, charges, products, and terms directly. No.
Why do I suddenly have big shiny flies in my house?
A sudden indoor cluster in one area often means a dead rodent or bird in a wall, chimney or attic. Finding and removing the source usually ends the problem within days. Metallic blue or green flies are usually blow flies, which breed in decaying meat, carrion and garbage. They are common indoors: Bertone and colleagues found blow flies in 48% of the 50 North Carolina homes they searched in 2012, a small regional sample that measured presence, not infestation.
Are drain flies common in houses?
It is not a national rate. Drain flies breed in the organic film inside drains, overflow pipes and rarely used traps. Scrubbing the drain and clearing the biofilm, not pouring bleach, is the practical fix. Yes. Moth flies, usually called drain flies, were found in 74% of the 50 North Carolina homes that Bertone and colleagues inspected in 2012. That is a small regional sample and measures presence, alive or dead, rather than an active infestation.
