Here is the recipe for anyone asking how to make a homemade fly spray for cows?
- Take 4 cups of apple cider vinegar.
- 20 drops of essential rosemary oil as it repels flies owing to its strong aroma
- 20 drops of basil essential oil as basil is a wonderful fly repelling herb plant.
- 20 drops of peppermint essential oil as peppermint is a major deterrent for flies.

What are the best fly control methods for cattle?
Several measures must be taken to control flies. Result-oriented measures will reduce the number of flies significantly.
A decline in population is observed once the waste, dump, and debris is removed from the ground. Regular removal of fly-breeding material is required to break the life cycle of a fly which on average lasts between 10 to 21 days.
The fight against flies has become a bit easier with ear tags or fly tags. Once harmlessly hung in the cattle’s ear, ear tags provide optimum fly control for 3 to 4 months. The chemicals on the tags may vary some not very good for the lactating cows. Check before buying. Wear on both ears and also on calves.
Backrubbers and Dustbags
Another weapon to help in this annual battle is dustbags. Dustbags hover across the gates and doorways to combat flies. Hang the bag low for the protection of calves.
Cattle rub themselves against objects or surfaces when harassed by the pests. Those surfaces and objects must be soaked with insecticide to repel flies.
Insect Growth Regulator
Feed-through insecticides help get rid of troublesome flies and manure-lying pests. These feed-through pesticides work by killing the pest at the larval stage of life. Insect growth regulators are added to the manure to stop the fly growth at the breeding stage.
Fly control during warmer temperature is a grief every livestock farmer is burdened with. Though daunting, fly control is possible with the top-notch fly control spray in combination with other pest control practices. The above-mentioned fly control sprays lend a helping hand in combating flies. A cattle farmer can opt for a cheaper homemade fly control spray to repel pests.
