[QUOTE="kyblockhead, post: 224623, member: 3603"] IGR (Insect Growth Regulator) is a feed through product. It is manufactured with a very large molecular size so that it merely passes through the digestive tract of cattle and is never digested so it never enters the blood stream nor meat. It is deposited into the manure so that the fly larvae do eat the chemical and it prevents the larvae from ever developing into adult flies. Note that it does not kill adult flies but merely prevents the development of new ones. Altosid has a clearance on horn flies which is the biggest economic pest. Other flies often lay eggs in rotten hay, silage, etc. so the IGR doens't work there because it isn't being deposited into those breeding areas. Most flies migrate very little and they only leave the host animal to lay eggs then return very quickly. It is possible for flies to leave the neighbors cows and come to your animals if they have a common fence area. IGR (Altosid) is effective but like most other things is only a part of a good management program. Hope that helps some. IGR (Altosid) is available in loose mineral, pressed blocks or tubs. Another option is Rabon oral larvacide which is also available in all 3 forms. Some resistance has been shown with the Rabon. [/QUOTE]
