🐴 Bot flies 🪰
Vet Nicky spotted some strange flecks on her horse's legs today and inspired us all to post! Have you ever spotted similar small white/yellow eggs stuck to your horse's hair over the summer? There is a good chance you could be looking at some Bot Fly eggs!
Bot flies lay their eggs on the horse's hair, most commonly around the legs, shoulders, and face. Horses may try to bite or lick at the areas where the flies are bothering them and sometimes accidently ingest a few!
So what can you do?
🪰 Remove the eggs – daily grooming and checks can help reduce bot eggs. Using a bot egg remover or bot knife can be useful for getting those stubborn little eggs off the hairs, taking care around sensitive areas such as the face.
🪰 Removing eggs regularly can help reduce the number of larvae your horse swallows while grooming.
🪰 Bot flies can be a nuisance, but seeing a few eggs on your horse doesn't necessarily mean there is a problem. A quick check during grooming can help keep on top of them throughout the fly season.
🪰 In some cases, larvae can be found incidentally during a gastroscope exam as seen in our picture! This would then prompt treatment with a good worming protocol from our vets to ensure the right wormer is used.
Have you spotted any bot eggs on your horse this year? 👀🐴
