\u201cSince much of the Southeast has such a long horn fly season, we recommend that producers use a pour-on, spray, or dust on their cattle in the spring.\u00a0 If you\u2019re getting up your animals to vaccinate and treat otherwise, this works okay.\u00a0 Once fly numbers start to take off, likely in early June, it is probably time to install ear tags.\u00a0 If organophosphate tags have been used more than the past three years in a row, it\u2019s likely time to switch to another mode of action such as a pyrethroid tag.\u00a0Similarly, if you\u2019ve used a pyrethroid continuously for the past three years, it\u2019s probably time to switch to something else.\u00a0 If neither pyrethroids nor organophosphates are providing the level of control you\u2019re seeking, consider using the abamectin tag (XP-820).\u201d<\/p>\n
\u201cSome producers are still getting good control using feed-through products containing insect growth regulators (IGRs) such as methoprene and diflubenzuron.\u00a0 Remember, these products prevent fly maggots from developing in the manure, but they do not kill adult flies.\u00a0 So, reductions in fly numbers on cattle will be apparent only a week or two later.\u00a0 And if your herd shares a fence line with a herd that is covered in horn flies, nothing will stop those flies from flying across the fence to infest your animals.\u00a0If ear tags begin to fail late in the season, consider treating with a spray, dust, or pour-on.\u201d\u00a0 Fly tag removal is also essential to help reduce insecticide resistance.<\/p>\n
\u201cOf course, fly control can always be supplemented using self-treatment devices such as back-rubbers or dust bags.\u201d \u00a0Dr. Hinkle suggests using pest control handbooks to understand which mode of action each product uses to determine rotation strategies. Your local University Extension is a good resource to find information on pest management information in your area.<\/p>\n
Lastly, although pour-on avermectin dewormers do provide some fly control, excessive use may cause internal parasites to build resistance to those products.\u00a0 You definitely want to avoid both internal and external parasite resistance.\u00a0 Work with your local veterinarian and Extension resources to develop a multi-year game plan targeted for your area and herd.<\/p>\n
