Does your lagoon system or wastewater treatment plant suffer from midge fly outbreaks? Midge flies, or chironomids, which resemble mosquitos but don’t bite, commonly occur in wastewater treatment and pond or lagoon systems, and along lake shores.

Aquabac
VitaStim 5000bt
Midges are often seen in large mating swarms over water. They lay their eggs in the water and in about ten days these eggs hatch to form larvae, often called red worms or “bloodworms” because of the presence of hemoglobin in the blood. Bloodworms love the nutrient-rich conditions in a wastewater treatment plant and feed off the bacteria and sludge. This is why a wastewater plant with a lot of red worms can watch their mixed liquor go down even though they are not wasting. In another ten days, the bloodworms mature into midge flies.

Midge Fly Life-Cycle
Midge flies have four stages to their life cycle.
- The adult midge
- The egg mass, which you'll find in the wastewater plant
- The egg forms a bloodworm
- The bloodworm forms the pupa, which hatches into the adult midge
Additionally, sometimes the bloodworms will colonize on the side of a tank. When they colonize, that’s called cacooning.
Midge Flies Eating Your Good Bacteria?
Aquabac is a highly effective, US EPA-registered biological larvacide. It contains a species of bacteria called Bascillus thuringienisis, commonly referred to as Bt. Bt works by producing a crystal that kills red worms that digest it.
“We had a terrible midge fly problem. We started dripping this weekly into our plant and the midge flies went away. I highly recommend this technology to any operator with these pesky flies.” Steve, Illinois Wastewater
“Works slick. They got so thick in our sand filter building we could hardly breathe. Aquafix told us about the Aquabac, and it works.” Jeff, Illinois Wastewater
“We had bad red worms in our sand filters. Aquabac knocked them out.” Larry, Wisconsin Wastewater
Sold in 5 gallon units, Aquabac can be dripped either into the head of your plant or before the clarifier, depending on where you have the problem. In a traditional activated sludge plant we start at 30 oz per 100,000 gallons of water. This dose is either metered in over a twenty four hour period or is spread out over a week. Apply this dose once per week until they are under control. Once they are under control the dose can be reduced.
If the problem is in the clarifier the products would be fed between the aeration basin and clarifier. Once the product is established, a reduced dose will do fine, most often plants will find 10-20 ounces is fine. Other plants will use 5 oz per 100,000 just to limit their activity. If the mixed liquor concentration is really high, or the plant gets a lot of grease we may couple this with our VitaStim 6000 or 5Alive. These products help to expose the red worms.
