IR3535 vs Permethrin Horse Rugs – What’s the Difference?

A standard fly rug provides physical protection by covering your horse's body. An insect-repellent fly rug, such as one treated with IR3535, combines that physical barrier with insect-repellent technology designed to discourage insects from landing on the rug in the first place.

Yes. IR3535-treated fabrics are designed to reduce insect landings by making the treated surface less attractive to many biting insects. Unlike a standard fly rug, the treatment helps repel insects before they have the opportunity to bite.

IR3535 and permethrin both aim to reduce insect pressure, but they work differently.

Many horse owners choose IR3535-treated rugs because they combine the physical protection of a fly rug with insect-repellent technology designed to help reduce insect landings.

No. IR3535 is designed to repel many biting insects rather than kill them. By discouraging insects from landing on the horse, it helps reduce the opportunity for bites while allowing the fly rug's physical barrier to provide additional protection.
