Operation Big Itch was a September 1954 series of tests at Dugway Proving Ground in Utah23 The tests were designed to determine coverage patterns and survivability of the tropical rat flea Xenopsylla cheopis for use in biological warfare as disease vector3 The fleas used in these trials were not infected by any biological agent4 The fleas were loaded into two types of munitions and dropped from the air4 The E14 bomb and E23 bomb, which could be clustered into the E86 cluster bomb and E77 bomb, respectively3 When the cluster bombs reached 2,000 or 1,000 feet 600 or 300 m the bomblets would drop via parachute, disseminating their vector3
The E14 was designed to hold 100,000 fleas and the E23 was designed to hold 200,000 fleas but the E23 failed in over half of the preliminary Big Itch tests3 E23s malfunctioned during testing and the fleas were released into the aircraft where they bit the pilot, bombardier and an observer4 As a result, the remaining Big Itch tests were conducted using only the smaller capacity E143 Guinea pigs were used as test subjects and placed around a 660-yard 600 m circular grid3
Big Itch proved successful,35 the tests showed that not only could the fleas survive the drop from an airplane but they also soon attached themselves to hosts6 The weapon proved able to cover a battalion-sized target area and disrupt operations for up to one day3 The one-day limit was due to the activity of the fleas; the air dropped fleas were only active for about 24 hours2
