A program was immediately undertaken to prevent further spread of the tick on the island, 
and an eradication program was quickly developed. All livestock on the island were immediately 
inspected. Later a second inspection was made, and in June 1969 all livestock were inspected again. 
The infestation was found to be limited to six contiguous premises involving some 2,600 acres. 
A. variegatum ticks were collected from cattle, sheep, goats, dogs, horses, and mongooses. 
The A. variegatum eradication program on St. Croix included insular quarantines on the 
infested premises; dipping all livestock at 7-day intervals (changed to 14-day intervals in August 
1968) in 0.125 percent coumaphos (Co-Ral); and spraying infested premises with 2 pounds of active 
ingredient carbary! (Sevin) per acre. 
In August 1971, a tick survey was made on the Islands of St. Thomas and St. John. A total of 
26 herds comprising 267 cattle, 23 horses, 121 sheep, and 97 goats was inspected. Numerous 
B. microplus and D. nitens but no A. variegatum ticks were found.
