Nettex Fly Repellent Advanced is a popular and trusted product containing powerful and long-lasting repellent. Effectively repels flies, stable flies, and all biting insects, keeping your horse or pony comfortable and happy at all times.

  • D.E.E.T based formulation.
  • Added moisturisers, conditioners and natural extracts to assist with the longevity of repellency.
  • Ideal for use where horses and ponies are kept in problem areas such as around ponds, streams and waterways that are heavily burdened with biting insects.

Made in the UK.


Shake well before use.

Patch test 48 hours prior to application if you have not used a D.E.E.T based product before or if horse is sensitive skinned.

Spray evenly over the coat but be careful not to saturate. If horse or pony is nervous of sprays apply to a cloth or sponge and wipe over the areas required.

For best results apply early in the morning before turnout and before heat of midday sun to allow the formula to dry and seal the hair. Avoid direct contact with mucous membranes. When fly infestation is very heavy, re-application may be required more frequently.

Avoid contact with broken or irritated skin. Not recommended to use under saddles, fly rugs or fly masks as may cause irritation.

Key ingredients: DEET – N,N-Diethyl-M- Tolumide, P-Menthane 3.8-diol.

  • If a fly rug is used during the summer apply Nettex Fly Repellent Advanced over the top of the fly rug to reduce flies landing and biting through the material of the rug.
  • Garlic can have natural insect detterent properties when added to the feed and many horses enjoy its taste, so it can be a useful addition to your insect avoidance strategy. Nettex Garlic Granules are made from the finest pure garlic cloves.
  • For an increased level of protection use Nettex Fly Repellent Shampoo weekly. This will coat the hair and help further prolong the effect of the Nettex Fly Repellent Advanced.
  • Nettex Fly Repellent Advanced is safe to use on pregnant and lactating mares, avoiding application around teats.

Archie is my 11yr old Cob/TB we like to compete in dressage and we won Nettex Associated Champion at Intro level in 2018, he also placed 6th at the preliminary in 2019. Archie had dermal testing last summer, our vets confirmed that he had 22 different allergies some of which are flies and midges. Archie’s allergies cause him to get itchy to the point where he would bite or rub himself raw. We first saw NETTEX Fly Repellent Spray on social media. When we first started using the product the results were seen within minutes he was much more comfortable and he had less flies bothering him. This product is by far the best we have tried. For Archie I wouldn't consider purchasing anything else as I know I have found the right product that works for him.

My 24 year old cob, Dice is very susceptible to irritation from flies and midges. After struggling to find a fly spray that remotely worked I contacted Nettex, who were extremely helpful and they recommended the Advanced Fly Spray. I tried a small bottle for a week and after seeing immediate results I bought another 6 big bottles. It’s fantastic, it really works and seems to suit her skin, not to mention it does not smell ‘chemically’ like other brands do, plus a little goes a long way which is great for me in terms of cost. Dice is now content when left in the field and she seems overall a much happier mare.

Great product, it’s working well against all the tiny midges which my horse’s skin reacts to and another flyspray didn’t work on. It smells quite strong, but not bad! The wipes and cream are also brilliant where he doesn’t like me spraying.



Love this product it's one of only three I've found to work on a pony with awful sweetitch and is extremely effective at dealing with midges. Lasts and smells not to bad
