H Trap Plus Professional Horsefly Trap
£159.00
13th July 2026: ‘SOLD OUT’. Â Very sorry to disappoint anyone who was hoping to buy an H-Trap as we are now sold out until 2027.
No hidden cost. Â The price you see includes VAT and delivery from our Monmouthshire store.
The H-trap controls horsefly numbers and is designed to be placed outdoors. The shape is designed to mimic an ideal target for female (the ones that bite) horseflies. The insects are ‘tricked’ into mistaking the trap as a large animal.
They are attracted to the heat from the large black ball. Once they land on the black ball, they will try to bite it and when they fail to obtain a blood feed, they fly upwards, where they are caught in the funnel and guided into a centrally placed collection chamber. Â This chamber can be kept empty where insects will dehydrate and die, or can be part filled with water to drown them. Change water often to avoid becoming stagnant.
New for 2026 now with a Blue/Black Funnel that dramatically improves horsefly capture.
Horse flies are visually driven insects. High-contrast colours and glossy surfaces are known to trigger stronger attraction responses. The blue/black striped funnel enhances visual stimulation, guiding more flies into the trap and increasing capture efficiency.

2026 Field Trials
In independent field trials, the blue black canopy out performed the standard green canopy. Â In the trials, to ensure reliable results, the traps were
• Operated continuously for six consecutive days
• Rotated daily to eliminate location bias
• Tested under stable summer-like weather conditions
The results were striking:
• Blue/black striped funnel: 830 horse flies captured
• Standard green funnel: 207 horse flies captured
That means in the trial the blue/black funnel captured over four times more horse flies than the standard design.
Why Does the Blue/Black Funnel Work Better?
Horse flies are visually driven insects. High-contrast colours and glossy surfaces are known to trigger stronger attraction responses. The blue/black striped funnel enhances visual stimulation, guiding more flies into the trap and increasing capture efficiency.
Proven Upgrade for Better Fly Control
This independent field study confirms that simply changing the funnel design can dramatically improve trap
performance – without chemicals, electricity or added complexity.
Key benefits of the blue/black funnel:
• Proven 4x higher capture rate
• Scientifically validated under field conditions
• Ideal for livestock environments
• Enhances effectiveness of the H-Trap unit
Conclusion:
The H-Trap with a blue/black striped funnel delivers significantly superior horsefly
control and represents a smart, evidence-based upgrade for professional users.
