Just read your question. I found it depends on the weather. The bottle does state that it won't hold up to major rains so it advises using the sheep dip version. However, that's another purchase. I compared the ingredients and from what I gathered, citriodiol is the active ingredient in a lot of the Barrier stuff. It's not citronella! I thought it was, but Google it, it's completely different! The cattle get bothered by horseflies and sheep get blowflies and call me tight, but if there is 1 product that's safe for all that will do the same job, then why not? Besides, last summer after quite a lot of "persuasion" and firm talking, the cattle shone! Will be doing the same this year! I've had maggots on maggots on some badly struck sheep and this stuff is deemed mild but strong enough and to spray the little b******s and watch them fall off the sheep makes me feel better. I had a neighbour's sheep here last year, wild little blighters, not a cat in hells chance to get near them and they had been dipped! Just a few days after the end of the coverage time and one lamb was looking rather down. I had to drive all sheep to the buildings for one mad hatter (mine, grab in the field), it was full of maggots. Neighbour came to shear it and by the time we'd finished it took a lot of barrier spray to 'empty' out the crawlies as they were under the skin. I resprayed it for the next few days. Now, just when it was recovering, flies started laying eggs again on it as the wound smell must have been too strong for the citriodiol to tackle. By then, the owner was back, he took it home and sprayed sheep dip over it. It did live.
