320 | Ask the Expert: Natural Solutions for Fly Control with Dr. Mike Catangui
On this episode of the Uplevel Dairy Podcast, Peggy Coffeen is back with Dr. Mike Catangui, of MWI Animal Health, to chat about natural insecticides for dairy farm fly control.
Dr. Mike describes growing dairy interest due to milk safety concerns about residues, environmental and sustainability expectations from consumers, and reduced risk of insect resistance. He outlines practical use of natural pyrethrins (derived from plants) that can be sprayed directly on calves, heifers and cows, and in sensitive areas where synthetic products may be restricted, supported by improved application tools like battery-powered foggers.
He cites research showing stable flies can reduce milk production 10–20% during fly season and estimates a strong ROI, including a prior calculation of $27 gained per $1 spent.
