Fly season is rough on horses, and constant chemical sprays get old fast, for you and them. A natural fly-repellent shampoo takes a gentler angle: it cleans the coat while leaving behind botanical oils — citronella, lemongrass, eucalyptus and tea tree — that insects would rather avoid. Ferro's [Repel Oil Shampoo](/product/repel-oil-shampoo/) is a wash, not a leave-on spray, so here's how it actually fits into your routine.

## A Repellent Wash, Used Honestly

[Repel Oil Shampoo](/product/repel-oil-shampoo/) is a bathing shampoo built around insect-deterring botanical oils. It's the cleansing, coat-conditioning base layer of a fly routine, not a substitute for a leave-on fly spray during peak season. Think of it as sending the horse out clean and less appealing to insects, then topping up with your usual spray wherever you need lasting, all-day cover.

### Using It During Fly Season

- Wash with [Repel](/product/repel-oil-shampoo/) the same way you would any shampoo, working the lather over the whole body.
- Let it sit a couple of minutes so the botanical oils coat the hair fully, then rinse.
- Dry the horse and, in peak season, follow up with your leave-on fly spray for staying power.
- Re-bathe every week or two instead of relying on the wash alone for all-day protection.

What 'Natural Repellent' Can and Can't Do

Botanical oils like citronella and eucalyptus do genuinely deter insects, but they're gentler and shorter-lived than synthetic actives — that's the trade-off for being kinder to skin. Use the wash to cut down the burden, and stay realistic: on a bad midge day, your horse may still need a dedicated leave-on repellent as well.
