Frequently Asked Questions (FAQs)

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?

The midges that are implicated with the transmission of AHS are Culicoides namely two sub species   Culloides c. Imicola  and Culloides c. Bolitinos.  The Imicola prefer to stay outdoos but the Bolitinos. is found to breed in horse manure and is also found in many cases indoors.


The most common sub species is Imicola  and therefore by implication stabling your horse will reduce the exposure to the greater number of midges and increase his chances of not getting AHS virus.
