Abstract [condensed]: Mowing vegetation is a recommended method to control ticks, but few studies have evaluated the efficacy of this practice. This study determined if a single mowing event could reduce the abundance of host-seeking ticks on recreational trails. The authors encountered a total of 3,456 ticks (2,459 Ixodes scapularis Say and 997 Dermacentor variabilis L.) during the 7-week study period. There were no significant differences in the abundance of I. scapularis (adults) or D. variabilis (adults only) between control and mown trail sections. Mowing was a significant predictor of nymphal I. scapularis abundance, but trended towards more ticks in mown sections compared to controls. These results suggest that a single mowing intervention during early June is likely to be ineffective as a strategy to reduce the risk of human contacts with ticks on trails.
Note: Vegetation was mowed to a height of 8 cm, but this did not appear to reduce the numbers of ticks that could be sampled by dragging, indicating there potentially was no impact on the risk of tick attachment.
