Dairy Operations

Because of the confined nature of a dairy operation, fly control is important not only to cows, but also to the people who work and live around them. Nuisance and biting flies are a vector of disease and an irritant. ClariFly® Larvicide targets all of the fly species present on a dairy operation – including house flies, stable flies, face flies and horn flies – making it an ideal fly control solution.

When recommending the use of a feed through such as ClariFly® Larvicide on a dairy operation, it is essential to point out that this is only one part of a complete fly management program. There is no such thing as a “silver bullet” for fly control issues; a multi-faceted approach will yield the best results. Further, to be fully effective, animals of all ages – from calves to active milking cows – should be treated with ClariFly® Larvicide. When only some animals are given treatment, fly populations that start amongst untreated animals can cross over to treated animals.

Understanding the Problem

In operations focused on livestock, flies are part of the bargain at certain times of year. This is especially true on dairy operations, where everything from cattle housing to the milk operation, can be infested. When fly populations are out of control, dairy operators feel it in the bottom line.

There are multiple ways in which fly infestations can affect profits on dairy operations. When animals are in the milking parlor, they may move around in an effort to dislodge biting flies. This can lead to damage and wear on equipment, as well as increased occurrence of teat lesions. Additionally, as a result of animal discomfort, producers may notice a decrease in milk production. Lastly, flies are a vector for costly diseases such as mastisis and pink eye; when conditions are right they can spread illness at alarming rates.

House Fly

  • Feeds freely on human food, fresh animal waste and rotting garbage
  • Prefers manure and warm decaying organic matter as breeding sources
  • Implicated in the transmission of more than 65 disease organisms, including the bacteria that cause mastitis

Stable Fly

  • Feeds on blood, inflicting painful bites on a variety of animals, including humans
  • Breeds in rotting vegetation, urine-soaked bedding and manure/vegetation mixtures
  • Shown to cause reduced milk production in dairy cows

Face Fly

  • Feeds on secretions around the eye, nose and mouth of cattle with sponging mouthparts
  • Typically lays eggs on fresh, undisturbed manure
  • A known vector of eye diseases, including infectious bovine pink eye

Horn Fly

  • Takes up to 40 blood meals with piercing mouthparts
  • Congregates on the backs of cattle, leaving only to lay eggs in fresh manure
  • Painful bites can interfere with feed efficiency and weight gain of cattle

Fly Management Through IPM

Effective control of costly, damaging flies on a dairy operation is dependent on a complete Integrated Pest Management (IPM) program. An IPM program incorporates several routine practices and control methods, in addition to a feed through that help keep fly populations in check and below an established economic threshold – the calculated number of flies per animal in which the economic losses outweigh the costs to control them.

Building an IPM program can be broken down to three phases; planning, implementation and evaluation.

How Feed-Through Products Work

Conventional insecticides – often referred to as adulticides – kill flies by attacking their nervous systems. Feed-through products such as ClariFly® Larvicide work by interrupting the fly’s life cycle rather than through direct toxicitiy. The active ingredient in ClariFly® Larvicide specifically targets flies in the larval stages of pupation by disrupting the proper development of an exoskeleton. Without an exoskeleton, flies are unable to survive into adulthood.

When a feed through like ClariFly® Larvicide is mixed into feed or feed supplements, cattle ingest it as part of their daily feed intake. It then passes through the animals’ digestive systems and ends up in their manure, where flies lay eggs. It is here that the fly life cycle is interrupted. Independent studies show that ClariFly® Larvicide can reduce fly populations in the manure of animals treated with ClariFly® Larvicide by as much as 96.7%.*

For best results, ClariFly® Larvicide should be added to your feed supplement 30 days before fly emergence (typically when average daily temperatures reach 65 degrees) and continued throughout the season until 30 days after the first frost. To learn more about the 30/30 program, download our 30/30 White Paper.

ClariFly® Larvicide Formulations

Selecting the right formulation of feed through is the key to effectiveness. It is not only dependent on the size of the operation and the intensity of the fly problem, but also on which products your organization has access to and actively sells.

ClariFly® Larvicide can be premixed and floor stocked at dealerships when proper end use registrations have been granted. End use registrations have been granted for numerous concentrations available in blocks, tubs, granules, add packs and finished feeds. ClariFly® Larvicide can also be custom blended into a producer’s specified ration when requested.

It is important to select the right formulation for your customer as well as your dealership. To find out which product best suits your needs, contact your ClariFly® Larvicide representative to get more information.
