CONTROL OF THE CATTLE TICK. 
Toowoomba. During the winter, very few ticks gave rise to progeny, 
but when such did occur, the period was usually between four and six 
months in all stations except Toowoomba, where none of the eggs in the 
plots survived the cold. 
From these results, it will be seen that. a quarantine period of six 
calendar months should be effective, very few of the periods having been 
found to extend beyond that length of time. 
The results obtained have led the author to form the opinion that 
cattle-owners in districts where the cattle tick occurs, whether sparingly or 
as a pest, should commence dipping early in spring (say September or 
early October), and continue it regularly. It is at this time that the 
larvee are few in numbers, and the menace could be most easily con- 
trolled. If the ticks which have survived the winter, either as eggs or 
as larvee, gain access to the host and are allowed to mature, then in a

comparatively few weeks’ time an enormous number of resulting larve 
are ready to infest the cattle. Cattle-owners should realize that they 
must dip their cattle before ticks become evident on the animals. By 
so doing, they will destroy the greater number of the tiny larval and 
nymph ticks already present on their animals, but whose small size 
prevents their ready detection by those in charge of the herd. 
A half-yearly rotation of paddocks would go a very long way towards 
the eradication of the cattle tick in Queensland. Combined with 
systematic and thorough dipping, such rotation would, in the writer’s 
opinion, lead to the control of the tick pest.
