Table 1.

Number of D. reticulatus collected in situ into the crates for the two treatment groups at 2 and 4 h post-infestation (proportion out of the 500 ticks used for infestation)

	Untreated control group number of ticks in the crate (percent out of the total number of ticks)	Treated group number of ticks in the crate (percent out of the total number of ticks)
Number of ticks and dogs Infestation Day	500 ticks/10 dogs	500 ticks/10 dogs
1	12 (2%)	178 (36%)
7	7 (1%)	294 (59%)
14	9 (2%)	271 (54%)
21	22 (4%)	262 (52%)
28	8 (2%)	203 (41%)

Number of ticks differed statistically significantly between treatment groups at each time count (p < 0.002).
