EPA-registered larvicide paired with an enzyme that breaks down red worm cocoons, exposing more larvae to treatment. Complete midge fly control program.

What it is

Midge Fly Complete pairs AQUABACxt, a US EPA-registered biolarvicide, with Lar-V-Zyme, an enzyme that breaks down red worm cocoons and the organic matter surrounding them. That exposure is what raises the larvicide's effectiveness, which is why the published dose rates assume both are used together.

TimelineFour week initial campaign

How it works

Red worm larvae shelter inside cocoons surrounded by organic matter, and a larvicide reaching only what is exposed leaves a substantial share of the population untouched. Lar-V-Zyme breaks down those cocoons and the surrounding material, exposing more larvae to the larvicide and lifting the effectiveness of the same dose.

The larvicide itself is AQUABACxt, carrying Bacillus thuringiensis endotoxins that are lethal to target larvae and harmless to treatment biology. Together the two products break the life cycle of midge flies, mosquito larvae and black flies at the larval stage.

Because the published dose tables are written as matched volumes of both products, this pairing is the normal way to buy it rather than an upsell. A site running the larvicide alone is dosing at rates designed around exposure the enzyme was meant to create.

Check these before you buy

These decide whether this product can work at all. If one fails, fix that first, because the money spent here will not survive it.

Confirm red worms are the problemDisappearing mixed liquor solids and stringy or clumpy return sludge are the process symptoms. Confirm microscopically before treating for the wrong thing.
Budget the full campaignFour weeks of initial dosing followed by two months of maintenance in a lagoon. Stopping when the swarms disappear is how a site repeats the campaign next season.
Set expectations about adult fliesNeither component affects adults already flying. If complaints are driving the purchase, whoever fields them needs the timeline in advance.

Is this the right fit

Good fit for

Heavy or established red worm infestations
Sites where larvicide alone underperformed
Midge flies, mosquito larvae and black flies together
Both lagoons and conventional treatment plants

Not the answer for

Killing adult flies already on the wing
One-off application without a maintenance phase
Problems that are not larval

Dosing and application

Plant, initial dose: Twice a week for 4 weeks. 100,000 GPD: 0.5 gal each. 500,000 GPD: 2.5 gal each. 1 MGD: 5 gal each.
Plant, maintenance dose: Once per week. 100,000 GPD: 1 pint each. 500,000 GPD: 5 pints each. 1 MGD: 10 pints each.
Lagoon, initial dose: Once a week for 4 weeks. 1 acre: 2.5 gal each. 4 acres: 10 gal each. 8 acres: 20 gal each.
Lagoon, maintenance dose: Once a week for 2 months. 1 acre: 1 gal each. 4 acres: 4 gal each. 8 acres: 8 gal each.
Case contents: 5 gallons AQUABACxt plus 5 gallons Lar-V-Zyme, which is two weeks of initial lagoon dosing on one acre.

What to expect, and when

Weeks 1 to 4The initial campaign. The enzyme opens cocoons while the larvicide works on the exposed larvae.
Week 4 onwardFewer emerging adults as the larval population collapses. This is the first fair test of the program.
Following two monthsMaintenance dosing holds the result. This phase is the one most often skipped and most often regretted.
Process sideMixed liquor solids and return sludge appearance recover as larvae stop feeding on the biomass.

How you prove it worked

Count emerging adults rather than adults in the air, and track mixed liquor solids and return sludge appearance. Both reflect the larval population, which is what the program actually targets.

Larvicide programs that underperform usually fail for a physical reason rather than a chemical one. Red worm larvae shelter inside cocoons surrounded by organic matter, and a larvicide reaching only the exposed population leaves enough behind to rebuild.

Pairing the larvicide with an enzyme that degrades those cocoons is what closes that gap. It is also why AquaFix publishes the dose rates as matched volumes of both products: the rates are calibrated around the exposure the enzyme creates, so running the larvicide alone is dosing against an assumption that no longer holds.

Everything else about a midge fly program is scheduling discipline. Four weeks of initial dosing to break the reproducing population, two months of maintenance to keep it broken, and the patience to judge results by what emerges rather than by what is currently flying.

Common questions

Why add an enzyme to a larvicide?

Because red worm larvae shelter inside cocoons surrounded by organic matter, and a larvicide only reaches what is exposed. The enzyme breaks those cocoons down so more of the population is actually treated by the same dose.

How much does a case cover?

A case is 5 gallons of each component. At the lagoon initial rate of 2.5 gallons of each per acre per week, that is two weeks of treatment on a single acre, so a full four-week campaign on one acre needs two cases.

Should I buy this or the larvicide alone?

The published dose tables assume both components, so this pairing is the normal purchase. Buying the larvicide alone makes sense only if you already hold Lar-V-Zyme.

Will it harm my treatment biology?

No. The larvicide's endotoxins are specific to target larvae and the product is US EPA-registered, which is why it is used in permitted systems where a broad-spectrum insecticide would be unacceptable.

The flies are still here. Did it fail?

Probably not. Neither component affects adults already flying; they have to die off naturally. Judge it by how many new adults emerge after the initial four weeks, not by what is in the air during them.
