AQUABACxt and Larva-Zyme
Larva-Zyme is a catalyst that degrades cocoons, exposing more of the worms to the Aquabac XT treatment. When used alone, we typically see Aquabac XT kill 70 to 90 percent of the redworm population, and dramatically decrease midge fly activity. By adding Bug Juice to the treatment, we can typically improve the kill to 100 percent, or very near 100 percent.

Midge Fly Impact on Wastewater
Midge flies, or chironomids (Chironomidae), commonly occur in wastewater treatment plants and pond systems. The red worm that forms the midge loves the nutrient-rich conditions in a wastewater treatment plant and feeds off bacteria and sludge. The worms will eat mixed liquor and once transformed into adults, clog filters and buildings entrances. Some operators have told us they couldn’t see past their hand in some buildings.
Red worms, also called blood worms, are found in mixed liquor. Over a period of ten days the eggs hatch into red worms and then pass through the pupa stage to become adult midge flies. With no aquatic life to feed on the midges, their life cycle runs uninterrupted, and they multiply fast. If left alone midge flies will cause poor settling, high TSS, and disrupt the bacterial environment. I mixed liquor infested by red worms can see reduced solids, stringy or clumpy sludge, and poor nutrient removal. Not to mention the midge flies are a nuisance that attract birds and spiders.
*There is no LC50 for aquatic organisms except for mosquito larvae. All other organisms except nuisance flies and midges Psychoda, Chironomus, and Chironomine are not affected by the product. Minnows, fish, Daphnia, even other aquatic insects can’t be killed by the active ingredient in the formulation. AQUABACxt is specific to mosquito, blackfly and midge larvae and again is not toxic to anything in the application sites except the larvae of these targets. The LC50 against susceptible mosquito larvae averages 0.15 micrograms per milliliter

AQUABACxt + Larva-Zyme: while AQUABACxt alone can kill midge flies, powerful lasting results come when using it in conjunction with Larva-Zyme.
AQUABACxt is a highly effective, US EPA-registered biological larvicide, but to work it must be able to reach the red worms. This is where BugJuice comes in to aid the larvicide. Red worms will use BOD to build protective cocoons around themselves, which AQUABACxt cannot penetrate. Larva-Zyme is a biocatalyst that specializes in dissolving tough forms of undigested BOD. Larva-Zyme is able to easily degrade the red worm cocoons so that the AQUABACxt can fully reach the red worms.
