Productive cattle starts with ClariFly

Product Information

Productive, fly-free cattle starts with ClariFly®

ClariFly® Larvicide is a feed supplement that prevents adult house flies, stable flies, face flies, and horn flies from developing in and emerging from the manure of treated cattle. Unlike conventional insecticides that attack the nervous system of insects, ClariFly® works by interrupting the fly’s life cycle, rather than through direct toxicity. When mixed into cattle feed, ClariFly® passes through the digestive system and into the manure. With only very small concentrations, ClariFly® is able to disrupt the normal molting process of the fly larvae. The mode of action of ClariFly® is specific to insects. It disrupts the production of a substance called chitin, a key component of an insect’s exoskeleton that is NOT found in mammals. Without a properly formed exoskeleton, the immature fly cannot survive to adulthood.

Not a Conventional Pesticide

The active ingredient in ClariFly®, Dimilin® brand of Diflubenzuron†, is considered by the Environmental Protection Agency (EPA) to pose a low risk to human health and the environment. Diflubenzuron has the following advantages over existing conventional pesticides:

  • Low impact on human health
  • Lower toxicity to non-target organisms (birds, fish, plants)
  • Low potential for groundwater contamination
  • Low use rates
  • Low pest resistance potential
  • Compatibility with Integrated Pest Management (IPM) practices

ClariFly® is able to exert its effect with little risk to human health and the environment and is therefore an ideal fly control choice for today’s environmentally conscious producer.

An Integrated Fly Control Program

Integrated Pest Management (IPM) is a pest control strategy that uses an array of complementary methods: natural predators and parasites, pest-resistant varieties, cultural practices, biological controls, various physical techniques, and pesticides as a last resort. It is an ecological approach that can significantly reduce or eliminate the use of pesticides.

ClariFly® should be used as part of an integrated pest management program aimed at reducing fly populations in the cattle’s environment. Adult house and stable flies can breed in decaying organic matter or silage. Good sanitation practices, such as cleaning up spilled feed and preventing manure build up around barns and fences or under feed bunks, will eliminate breeding sites for these flies.

Adult flies can also migrate from other areas. In these situations supplemental fly control measures may be needed in and around barns, calf pens, and dry lots. On-animal and premise insecticide applications and/or the use of traps and baits may be necessary to control these migrating adult flies. Visit StarbarProducts.com for more information.

Feeding Recommendations

Begin feeding ClariFly® early in the spring before flies begin to appear, and continue feeding though the summer and into the fall until cold weather reduces or ends fly activity. The actual feeding period will depend on the regional climate. Starting a program during the fly season will require the use of other fly control measures to reduce the existing adult fly populations. ClariFly® prevents the emergence of house flies, stable flies, face flies, and horn flies from the manure of treated cattle. It has no effect on existing adult fly populations.

To control manure-breeding flies, all cattle on the premises need to consume adequate quantities of ClariFly® every day. The feeding level for this product is 0.10 mg of Diflubenzuron per kg of bodyweight per day. Daily consumption of ClariFly® by individual animals may vary. However, fly control will not be affected.

Feeds and supplements containing ClariFly® may be fed up to slaughter and to lactating dairy cows without withholding the milk from market during or after treatment.
