I do find that this product is expensive, if it were double the amount it would be a lot better value. However, this product works within hours of application and has continued to work weeks after.

Service from Viovet very good.
Dotty suffers extremely badly from sweet-itch. Given the opportunity will rub herself raw around her head and elsewhere on her body.
She wears full fly-sheet covering, except in winter. Butox Swish pour on purchased on a vet's recommendation "that it was worth trying". It was applied a few days as directed. She has since rubbed raw patches on her face, but less then last year.
Conclusion: in Dotty's case it may be helping, but it is not the total solution to the problem she has.

Can this product be used on horses

  • VioVet Staff

This product should not be used on horses. I would recommend one of the DEET products, which are very effective, though have to be applied more often. There are lots of examples, just put DEET into the search box on our website.
