This stuff is amazing. We live on a farm in rural NSW and have pet sheep which attract many flies. Our backyard has the Murray River running through it. In summer the temps get into the high 40's and the flies, sandflies, midges and mozzies are everywhere. I bought one bottle to try it and 2 days after getting it in the mail I am about to order 2 more. What a relief to walk outside and not get covered in flies or bitten by mozzies at dusk. Thanks so much Seamus for getting the mosi guard to me so quickly, I am looking forward to a summer with no bites or itches. So impressed that it is natural as Deet is a dangerous poison and not as effective as this. I even put some on my sheeps heads and backs and they seem fine with it and it has reduced the flies on them as well. Great product which will be in my cupboard forever!!!!!!
