The H-trap controls horsefly numbers and is designed to be placed outdoors. The shape of the large black ball mimics an ideal target for female horseflies (the ones that bite) and they are ‘tricked’ into mistaking the trap as a large animal. The ball absorbs heat from the sun and the flies are then attracted to the heat when emitted.
Once they land on the 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.
Getting the best from the H-trap
- Horseflies breed in damp ground
- To maximise the interception of horseflies before they reach their target prey, identify their likely flight paths from damp areas such as around ponds and riverbanks, etc to where humans or animals congregate
- Decide if more than one H-trap is required
- Position the H- trap(s) between these areas, but closer to places where animals congregate e.g. around gates and near stable yards
- Place the H-traps early, preferably just before the first adult horseflies emerge in April/May
- Check traps weekly, emptying and topping up with soapy water as necessary
- If the H-trap is not catching sufficient numbers of flies and you are sure adult emergence has started, reposition the trap
Where to use your horsefly trap
Horse flies are typically found in damp ground, where there is long grass or heavy undergrowth and are typically associated with the following places:
• Horse stables or paddocks
• Lakes, streams, ponds or dams
• Golf courses, gardens & waterparks
• Amusement parks
• Cattle farms, meadows

- Shipment: The trap will arrive disassembled and needs to be constructed on location.
- Manual: An English language manual is included.
- Packaging: 110cm (L) x 31cm x 21cm.
Before Assembly: While unpacking your H-Trap, check for any signs of shipment damage. Your trap was checked prior to it’s final dispatch to you but we like to ensure it arrives with you complete and in the best condition. If you have any concerns, contact sales@sentomol.com.
Choice of location: The H-Trap should be installed near to where the problem exists. If you have horses, this may be close to where they stand or rest. Chose a sunny location as the ball is heated by the sun rays.
Required materials: A pump and small spanner are provided. In addition you will require a heavy hammer and possibly a spade or implement to loosen the soil if compacted. If the soil is particularly dry, a hose may be required to dampen the ground.
Installation:
1.Decide where to place the ground spike and prepare the ground if it is hard and compacted.
2.Using a heavy hammer, drive the ground spike into the soil. Take care not to damage the top of the spike and use a block of wood if there is a risk.
3. Drive the spike into the ground, until the anti-rotation anchor comes into contact with the soil.
4. Add the middle section (‘S’ shaped) by dropping the larger open end over the top of the ground spike. Using one of the long bolts, match up the corresponding holes and secure both sections with the bolt and nut. Place the washer between pipe and nut. Do not tighten at this stage.
5. Mount the top section (‘C’-shaped) of the tubular from onto the middle pipe and repeat the process with a second bolt and nut.
6. Attach the mounting bracket to the gimbal of the catch chamber ring into the last opening section and inset onto uppermost section of the frame. The velcro section should hang below the gimbal.
7. Tighten all nuts
8. Inflate the ball using the hand pump provided or a suitable compressed air unit or camping bed pump. Be careful when using compressed air not to over inflate. Insert white stopper.
9. Insert the 3 white poles into the hem of the funnel. There is an opening provided for this. Insert one at a time and then join the next section and push through. If there is any resistance or friction, use some liquid detergent soap to make the process easier. The last section will require a little manipulation to attach the first and third poles, but eventually the 3 sections will form the circular hoop of the funnel.
10. Attach the funnel to the metal stand by means of the velcro fastening
11. Attach the metal pendulum or ball hook to the top of the ball so that the square end holds the ball. Lift the ball into place under the funnel by lifting one side of the funnel to expose the gimbal.
12. As an alternative you can place the funnel over the top of the ball so it rest on top. Attach the pendulum and lift the entire funnel and ball into place to attach the pendulum. Then the velcro funnel section can then be attached.
13.Place the collection chamber into the top of the gimbal.
