  • The best fly sprays for horses are an absolute lifesaver in the summer months – they are highly effective and long-lasting, which negates the need for constant reapplication. Flies are a general nuisance, but for some horses their bites can lead to reactions and persistent itching and discomfort. With a wide range of flying insects across the country, protecting your horse can present a challenge. 

    Preventing flies from landing in the first instance is the best solution for protecting your horse – in addition to fly sprays, you can use fly gels, lotions or washes as well as fly masks and fly rugs to arm your horse with a full defence. Fly gels are particularly handy if your horse is averse to the spray. It can be a case of trial and error to find out what works for your horse, but once you’ve found a solution you can buy in bulk and save money in the long run. Some owners swear by their own home recipes

    Some fly deterrents contain synthetic active ingredients such as DEET or permethrin, some of which are insecticides, while other sprays contain natural ingredients known to deter a range of flying insects. Some formulas will need to be reapplied more often than others, so while some appear to be more expensive they may last you a lot longer. It’s also wise to consider the bottle and spray type – finding a gentle and quiet spray with good coverage can be difference between a calm and stressful turnout routine. 

    In the UK there are a lot of restrictions about what can be called a fly repellent, what can be applied to your horse and how companies can talk about different products. This guide includes a full range of fly deterrents – those you can apply to your horse, as well as those that should be applied to his living area or your feed room. Some products in this guide have been approved for use on animals in the US, while in the UK they are only approved for premise use around horses. Anyone choosing to use the spray in a manner that is not in line with the guidance on the bottle’s label, does so at their own risk.

    Here is a selection of some of the best fly sprays for horses and their premises…
