Aktiv Equine FlyTek Ultra Insect Repellent 5L
Aktiv Equine FlyTek Ultra 5L is a powerful insect repellent for horses, formulated with 15% DEET and a blend of selected natural oils to help repel flies, biting flies, mosquitoes and Culicoides midges.
The ready-to-use liquid can be sprayed or wiped directly onto the horse’s coat, making it a practical choice for everyday fly control during the warmer months and in areas with high insect activity.
Its DEET-based formulation is particularly useful where mosquitoes and biting midges are a major concern. Horses may also be ridden or worked immediately after application, making it convenient for competition yards, riding schools and everyday horse owners.
Aktiv Equine FlyTek Ultra Powerful Fly and Midge Repellent for Horses
Flies and other biting insects are more than simply annoying to horses. Persistent insects can cause tail swishing, stamping, head shaking, skin irritation and general restlessness, potentially making grooming, riding and stable time uncomfortable.
The formula helps repel:
- Flies
- Biting flies
- Mosquitoes
- Culicoides midges
These insects are particularly active during warmer weather, especially around dawn and dusk.
Regular topical insect control can therefore form an important part of a broader stable and horse-management programme during spring and summer.
Aktiv Equine FlyTek Ultra with 15% DEET
The primary repellent ingredient is DEET, or diethyl toluamide, at a concentration of 15% m/v.
DEET has a long history of use as an effective insect repellent and is commonly used to discourage mosquitoes, flies and other biting insects from landing.
Aktiv Equine specifically formulated this equine product to provide strong repellent action against insects that can cause significant irritation to horses.
Natural Oil Blend
The formulation combines DEET with selected aromatic oils and compounds, including:
- Eucalyptus oil
- Tagete oil
- D-limonene
- Alpha terpineol
These ingredients complement the main repellent action while providing a formulation specifically designed for topical use on horses.
Importantly, the product does not contain citronella oil.
Current retailer product information also lists piperonyl butoxide at 1% m/v as part of the formulation.
Ideal for High-Insect Seasons
This horse fly repellent is particularly useful during spring, summer and autumn, when fly, mosquito and midge activity is at its highest.
It can be used as part of the daily care routine for:
- Horses kept outdoors
- Competition and performance horses
- Horses in high-fly areas
- Horses exposed to mosquitoes and midges
- Horses that become irritated by biting insects
- Stable yards with seasonal insect problems
- Horses travelling to areas with high insect activity
Because horses can be worked immediately following application, it is also practical to use before riding or training.
Directions for Use
Shake the container thoroughly before each application.
The manufacturer’s retailer guidance recommends shaking the product at least 10 times before use to ensure the ingredients are properly mixed.
Apply the repellent to the horse by spraying or wiping it evenly over the coat.
For best insect protection:
- Apply during the early morning and late afternoon, particularly when biting insect activity is high.
- Pay special attention to the legs and other areas with thinner hair or exposed skin.
- Ensure the product is distributed evenly over the areas that require protection.
- Reapply according to conditions and the current product label, particularly where heavy insect pressure is present.
Horses may be ridden or worked immediately after application.
Avoid spraying directly into the eyes, nostrils, mouth or other sensitive areas. For the face, applying the product to a cloth first and carefully wiping the required areas is the more controlled option.
Always follow the directions and precautions printed on the current container.
Insect Control and African Horse Sickness
Culicoides midges and mosquitoes can act as vectors for certain equine diseases.
Using an effective insect repellent can help reduce contact between horses and biting insects. However, insect repellent should never be considered a replacement for vaccination or other recommended disease-control measures.
Aktiv Equine retailers specifically advise that appropriate vaccination programmes and other control measures remain essential where diseases such as African Horse Sickness are a concern.
