Frequently Asked Questions (FAQs): Preventative Measures (excl. vaccination)

  • I have put a fly rug on my horse that covers his neck and body. I have heard that the midges are so small that they can penetrate the small mesh holes in the rug. Is this true or will the rug provide some barrier between the midges and the horse? I put it on him at 4pm just before he comes in at 5pm for the night however he was getting too hot so i only put it on at about 5 if I am not riding. I cannot afford the amount of grass needed to bring in him at 3pm and out at 9am. Thus I am trying to reach a compromise?

  • Hi.We are putting day sheets on our horses when stabled at night. From 16:00 to 10:00 the next morning when they go out. Is this in ANY way effective?

  • I think I have heard somewhere that cironella should not be used on horses as it does deter flies, but actually attracts the AHS midgies. Is this correct? I use Deltab dip once a week, is this much good?

  • I have read that you said that prime biting time is between sunset and midnight and that the midges are attracted to odour and CO2 ommissions. Surely then, horses stabled in open stables without 80% shadecloth or any other methods to prevent midges from getting to them would be better off outside where there is airflow during these times?

  • What would you recommend to large breeding in protecting their horses. They can't possibly stable 100 + horses, and have to live out in the felt?

  • Good day. I have heard from our vet that horses are dropping like flies from AHS. We stable in Randjesfontein, Midrand area. I have a few questions: We have a mare & her foal who is now only 5 months old who are out 24/7 (in grass paddock; no stable) We are putting Peaceful Sleep (PS)on them (this is what the vet recommended we use). We are currently using the stick (instead of the cream or spray). Is Peaceful Sleep better than Tabbard? Does it make a difference which kind we use (spray, stick or cream). Are there any parts of the horse that are at greater risk of being bitten (eg legs or under the tummy)? We are currently only able to treat them in the late afternoons (after work); does this mean they are at increased risk of exposure in the mornings (effect of PS warn off)? Can we overdo the insect repellant and poisen the horse (we even put PS on their faces and around the ears)? Is there anything else we can do (eg feed lots of garlic)? Are our other horses who are stabled at night safer from being bitten? One of the mares in our yard who gave birth last week, who is stabled at night at this stage, was confirmed as having AHS - will this increase the risk to other horses stabled near her? Is there anywhere where we could find more accurate record of confirmed and suspected cases per area (your map only indicates one incident in the Midrand area)? thanks thank you?

  • I have 20 horses in Laikipia, central Kenya. It is a real hot spot for AHS and I have lost 4 horses in the last 10 months - all vaccinated. I am planning to build a new stable block that will be midge proof. Do you have any advice on design and materials that have proved successful?
