Tea Tree & Citronella Shampoo for Horses
Tea tree and citronella act as natural insect deterrents when used in a wash — milder and shorter-lasting than a synthetic spray, not a replacement for one. Ferro's Repel Oil Shampoo is an oil-based bathing shampoo built on tea tree, citronella, lemongrass, and eucalyptus. It cleans the coat and leaves a light, deterring finish behind. This is a wash, not a leave-on spray.
What's in This Wash, and What It Actually Does
Repel Oil Shampoo is an oil-based bathing shampoo built on botanical oils — citronella, lemongrass, eucalyptus, and tea tree. Worked through the coat, these oils clean the way any shampoo does, then leave behind a scent and a light oil residue that flies and other biting insects tend to avoid, for a while anyway. It's a cleansing wash first; the deterrent effect is a bonus of the formula, not the point of it. Read more on citronella and tea tree for horses and eucalyptus and lemongrass for horses.
- Citronella and lemongrass — classic insect-deterring botanicals
- Eucalyptus — adds to the deterring scent profile
- Tea tree — a cleansing botanical, not a medicated antifungal treatment
- Oil-based formula — cleans while leaving behind a light protective residue
A Wash, Not a Leave-On Spray
During heavy fly season, bathe with Repel Oil Shampoo on your normal washing schedule rather than every day — over-washing dries the coat no matter what's in the bottle. Pair it with a leave-on repellent for coverage between baths. See our summer fly grooming guide for a full seasonal routine.

Frequently asked questions
Is Repel Oil Shampoo the same as a fly spray?
No — it's a rinse-out wash for bath time, not a leave-on spray.
Does tea tree treat fungal infections on the skin?
No. It's a cleansing botanical, not a medicated antifungal treatment — a genuine infection needs a vet.
How long does the deterrent effect last after a bath?
Expect hours, not a full day — botanical deterrents like these fade faster than synthetic repellents.
Can I use this shampoo at every bath?
Yes. It cleans like any regular shampoo, so it fits right into your normal wash schedule.
