2014: Comparison of Adult Tabanidae (Horse Fly) Collections at a Wildlife Refuge
Near a Horse Boarding Facility in Cedar Key, Florida

The United States Department of Agriculture conducted testing in the summer of 2014, comparing horse fly collections from two commercial traps, the H-Trap and the HorsePal, and one standard surveillance trap, the NZI,  in a wildlife refuge that was near a horse boarding farm in Cedar Key, FL.  Researchers set up these three different style traps, per each manufacturer’s instructions, using no added attractants.   On the first day, the researchers placed the H-Trap, HorsePal, and NZI traps at one of three sites, and then rotated them 24 hours later.   This method allowed all three traps to be tested at each site.   The researchers conducted three repetitions, and recorded the total number of Tabanids collected over time.   The total number of horse flies collected was 3483; of that number, the H-Trap alone collected more than half (57.5%) of the total number of horse flies!

2015: Comparison of Adult Tabanidae (Horse Fly) Collections in Massachusetts

In the summer of 2015, the Cape Cod Greenhead Fly Control Project, a division of the Mosquito Control District, compared the efficacy of the standard Cape Blue Box trap with the H-Trap horse fly control system for the collection of Tabanids.   Both the H-Trap horse fly control system and the Blue Box were baited with the same experimental lure.   Two of each trap type were used in the testing at four sites in Northern Cape Cod.   Each morning, the researchers emptied the traps just before 10 a.m., placed new lures in the traps, and ran the testing for three hours.  Traps with lures were rotated between sites in order to prevent uneven population densities from skewing the test results.  Testing took place at the four sites over 10 days, and the total number of Tabanids collected over time was recorded.   The total number of horse flies collected was 5352; of that number, the H-Trap significantly collected more horse flies (almost 60%).

2016: Comparison of Adult Tabanidae (Horse Fly) Collections in Massachusetts

Testing of the  H-Trap Professional Horse Fly Control System in Cape Cod continued this July for the third straight year by the the Cape Cod Mosquito Control District and its division the Cape Cod Greenhead Fly Control Project, again under the watchful eyes of Gabrielle Sakolsky-Hoopes and Bart Morris, respectively.   This year Orleans, MA was the test location for catching horse flies known as green heads.

During the experiments charted below, the H-Trap  horse fly control system  and the Blue Boxes were baited with no lure and an octanol lure.   In  total, the testers conducted 13 repetitions and collected 872.5 horse flies with four traps.    In all comparisons with lures as seen in the charts below, the H-trap performed significantly better than the Cape Cod Box trap.
