What It Is

Commercial fly control that solves the source, not just the swarm

Fly problems in Indianapolis commercial kitchens, bars, and food-processing facilities almost never come from outdoors. They come from drains, neglected floor sinks, damp mop closets, dumpster pads, organic buildup under equipment, and occasionally from phorid flies breeding in broken sewer lines under the slab. An aerosol knockdown on adult flies makes the room look better for a shift, then the larvae hatch in the biofilm below and the swarm is back by the next weekend. Real fly control is source control, and source control starts with diagnostics.

Our technicians identify the species first, because drain flies, fruit flies, phorid flies, and house flies each have different breeding substrates and each demand different treatment. We inspect drains with scopes where needed, check floor-sink condition, look under equipment for organic buildup, and investigate slab penetrations for phorid fly evidence. Treatment combines biological drain cleaners that digest biofilm, targeted residual and non-residual materials, mechanical devices where appropriate, and a sanitation plan for your team. Every program is documented for health inspections and scheduled around operating hours.

In Their Words
We had drain flies bad enough that guests were mentioning them in reviews. Two companies came out, sprayed, and charged us for swarms that came back in five days. ProTech spent the first visit identifying species and finding the actual sources — two floor sinks nobody had cleaned properly in years and a cracked grease line under the dish pit. They treated with biological drain cleaner, coached the team on nightly drain care, and scheduled bi-weekly service. Flies were visibly gone within three weeks. Review complaints stopped entirely.

How It Works

Our 4-step commercial process.

Structured, documented, and built around the compliance standards your facility faces.

01

Species diagnosis

A technician identifies the species, inspects drains and floor sinks, checks under equipment for organic buildup, and investigates slab penetrations where phorid fly activity is suspected.

02

Source treatment

Biological drain cleaners digest biofilm, targeted materials address adult populations, and sanitation recommendations go to your team in writing the same day as the inspection.

03

Recurring cadence

Bi-weekly or monthly visits maintain drain treatment, inspect for new sources, and adjust protocols as operations change. Staff coaching keeps nightly drain care consistent.

04

Verification

We track adult fly activity visit over visit. When counts stay at zero through a full seasonal cycle, we right-size the program to a maintenance cadence that protects against reintroduction.

What's Included

Every program delivers this baseline.

Specialty services and add-ons layer on based on facility type. This is the foundation.

Species ID

Drain, fruit, phorid, and house flies all require different treatment — identification is the first step every visit.

Drain scope

Visual scope inspection of drains where biofilm, cracks, or sub-slab issues are suspected.

Biological treatment

Enzyme and microbial drain cleaners that digest biofilm rather than just flushing it temporarily.

Floor-sink focus

Inspection and treatment of neglected floor sinks, a top overlooked fly-breeding site in commercial kitchens.

Phorid diagnostics

Investigation of slab cracks, broken sewer lines, and sub-floor voids when phorid flies are confirmed.

Mechanical devices

LED fly light traps placed out of sight of customers for monitoring and ongoing capture where appropriate.

Sanitation coaching

Practical nightly drain and equipment-base routines for your kitchen and bar team, in writing.

Audit documentation

Written service reports, SDS, and trend logs aligned with health-inspection and third-party food-safety expectations.

Re-service included

If fly activity spikes between scheduled visits, we return at no additional charge.

How We Compare

ProTech vs. typical national pest control.

Most buyers hire a national chain because the brand is familiar — then deal with rotating technicians, sub-contractors, and call centers. Here's how ProTech is structurally different.

Frequently Asked

Commercial Fly Control — common questions.

Why do fly problems keep coming back after aerosol treatment?+
Because aerosol only kills adult flies that happen to be in the room at that moment. Every fly species driving commercial problems — drain flies, fruit flies, phorid flies — breeds in organic substrate: biofilm in drains, fermenting residue in floor sinks, decomposing material under equipment, or broken sewer lines under the slab. Larvae in those substrates hatch into adults on their own timeline, so aerosol knockdown buys you a few days at best. Real fly control kills the source, which means treating the biofilm and the buildup, not just the room.
How do you tell drain flies, fruit flies, and phorid flies apart?+
Size, shape, wing pattern, and behavior all differ. Drain flies are small, fuzzy, moth-like, and rest on walls near drains. Fruit flies have red eyes and hover around fermenting fruit, beer drains, and garnish stations. Phorid flies are small, humpbacked, and run in short bursts on surfaces rather than flying. Phorid flies in particular are a red flag because they often indicate a broken sewer line or organic material under a slab, which is a sanitation issue far more serious than what the swarm itself suggests. Species ID drives every treatment decision.
What is a floor sink and why does it matter so much?+
A floor sink is the small recessed drain under ice machines, soda lines, and dish machines that collects indirect drainage. In almost every kitchen we inspect, at least one floor sink has been ignored for months or years, and the biofilm inside is a near-perfect drain fly breeding site. They are hard to see, hard to clean, and easy to forget. Our inspections specifically check every floor sink, and our sanitation coaching includes nightly floor-sink care as a standard routine for your dish team.
Do you work with our chef and operations team on sanitation?+
Absolutely. Fly control without sanitation is a losing battle, and we are direct with chefs and GMs about what we need from the kitchen side. After every inspection we leave a written sanitation and source-removal plan: drains that need nightly enzyme flushing, equipment that needs to be pulled and cleaned monthly, floor sinks that need daily attention, dumpster areas that need tightening up.
Are the drain treatments safe with food prep happening?+
Yes. The biological drain treatments we use are enzyme and microbial formulations designed specifically for food-service environments. They work by digesting organic biofilm, have no residual toxicity for food-contact surfaces, and produce no harsh odors. Adult fly treatments in kitchen environments are low-toxicity, low-odor materials applied as targeted residuals or crack-and-crevice, never fogged or broadcast-sprayed across prep areas.
What if we have phorid flies under the slab?+
Phorid fly activity coming from a slab crack or broken under-slab sewer line is a serious issue and is diagnosed with careful inspection, sometimes including emergence traps placed over suspect cracks. If we confirm a sub-slab source, treatment alone will not solve it — a plumber needs to scope the line and repair the break. We document findings with photos, coordinate with your maintenance team, and continue surface-level fly control while the structural repair is scheduled.
Can you service multiple restaurant locations under one program?+
Yes. Multi-location programs are a significant part of our commercial book. We standardize the protocol across every location — species ID, biological drain treatment, floor-sink inspection, sanitation coaching — while documenting each site individually for health inspections. Corporate QA teams get a consolidated view of trends across the group, and location managers get the same consistent service experience regardless of which site they run.
