Fly Control in Swine Operations

February 3, 2020

This past week, I was fortunate enough to attend a swine nutrition meeting where a topic of discussion was fly control in swine barns. The Central Life Sciences rep gave a presentation on a feed supplement called Clarifly. Clarifly Larvicide has been a commonly used product in the cattle industry. And recently, swine was added to the label in Jan of 2016 featuring the active ingredient of diflubenzuron. Flies impact employees, animals, and possibly neighbors. By controlling the emergence of manure breeding flies, you can reduce the stress caused to pigs which affects feed intake and weight.

Secondly, with the threat of disease being transported to pigs through flies, Clarifly may help ease the mind of producers. Even during the winter months, flies, such as the dark-eyed, fruit fly, remain an issue. Clarifly can be used in breeding, gestating, and farrowing buildings, along with nurseries and finishing barns, for protection against flies and Indian meal moths. The Indian meal moth is usually the culprit for building the webby nests that often clog the drop tubes for gestation feed systems.  

Clarifly works differently than most insecticides whose action is to attack the nervous system of an insect. When mixed into feed, Clarifly passes through the swine’s digestive system into the manure, thus disrupting the molting process and preventing emergence of adult flies. A 2,400 head finishing swine operation in Ohio gave results of a 5-week trial after years of battling flies with no results. Clarifly was fed to the swine and hanging fly traps were hung to collect flies for counting. By week 2 and 3, fly populations decreased by 27%; and by week 5, each room showed a 99% reduction in flies with no room totaling no more than 10 house flies.

Keep in mind that fly management programs need to be proactive to protect the pigs, employees, and profits. By reducing the presence of flies, you will be reducing the stress on pigs that can affect feed intake and weight. For more information, contact your local Central Valley Ag feed location.
