Flies are a constant nuisance

The H-Trap Professional Horsefly Control System uses no chemicals and yet can reduce horsefly numbers to give long term protection to you and your animals. It uses the female horsefly’s natural hunting instincts against it, by providing an artificial target for it to land on and then become captured. Removing female flies has a long term effect on the breeding population and so reduces their presence and biting threat over successive years.

First introduced into the UK by Sentomol in 2013, the H-trap system has grown in use and popularity and many British horse owners have added their voice to the success that has been experienced all around the world.

Extensive independent trials have shown a reduction of 90-95% in horsefly numbers in areas protected by H-traps can be realised.

In 2016 Sentomol are introducing the H-Trap’s baby brother, the MT-Trap, which adds greater flexibility in creating an area-wide, fly-free zone and an affordable option for those non-horse owners wishing to also have protection in gardens, around swimming pools, while camping and in other public spaces.

Sentomol specialises in the supply of insect pest management products and in addition to the H-Trap available in our webshop, we offer a range of additional fly management products for use in and around the stable and other outdoor working environments.

Sentomol is a pest management product supply company that aims to deliver monitoring and trapping solutions that can help manage insect pest problems without using or minimising the use of pesticides.  We are involved in various novel projects investigating how pheromones, attractants and traps can best be developed and adapted to learn more about the pest species we live with and  to produce tools to help manage them.

We supply not only the UK but we annually ship to 4 of the 7 continents and are working hard to find customers within the other 3.  If you are interested in any aspect of our business, or wish to source products and are outside the UK, then please do get in touch. We’d be pleased to hear from you.

SWHP, Society for Welfare Horses and PoniesSentomol first saw the benefit of the H-Trap for controlling horseflies when the traps were tested at a nearby horse hospital. Since then Sentomol has been pleased to provide horsefly traps to the Society for the Welfare of Horses and Ponies, which has been run as a horse hospital for more than 35 years. The SWHP takes in sick, injured or abused animals and nurses them back to health.

SWHP is run from the MacGregors’ farm at St Maughans, near Monmouth, South Wales, where the buildings have been adapted to stable up to 35 horses and ponies in easily managed conditions and 30 acres of grass provide grazing.

Anyone wishing to see the horsefly trap in action can visit on one of the regular Open Day events or during a POP IN SUNDAY, (see website for details) when the SWHP will be open to the public between 11.30am and 14.30pm.
