[QUOTE="milesvb, post: 31092, member: 413"] About two months ago we treated our herd with Cydectin. Now at the beginning of June, heel flies (gad flies) are plaguing the cattle and causing them to run around with their tails in the air. My question is if there is enough residual toxicity to kill the grub when it enters the body at this time or if another treatment is necessary the next time we pen (end of June or so)? I would like to know at what point killing the grubs in the cow's system will endanger the cow. I would really like to interupt the life cycle of these heel flies and reduce the problem in the future. Any advice is appreciated. [/QUOTE]
