Veterinarians across North America are reporting that ticks are appearing on pets earlier in the 2026 season than ever before [1].
This trend increases the risk of tick-borne illnesses in pets and humans, as owners may not have started seasonal preventative treatments. The shift suggests that traditional seasonal windows for pest control are no longer reliable.
Practitioners in Canada and the U.S. have observed these early surges, with specific reports coming from Florida and Vermont [1], [2]. Multiple U.S. states are experiencing early tick surges [4]. Veterinarians said peak tick season is underway [2].
Warmer temperatures and longer warm periods are causing ticks to become active earlier in the year [1], [4]. These climatic shifts allow parasites to emerge from dormancy sooner than in previous years. This environmental change is compounded by gaps in year-round prevention, which contributes to higher exposure for animals [1], [3].
Medical professionals are urging pet owners to remain vigilant and maintain consistent preventative care. Because ticks are active sooner, the risk of infection begins well before the traditional peak of summer. Experts said people should be on the lookout for ticks [5].
In previous years, some regional veterinarians said ticks and fleas were worse than they had ever been [3]. The current 2026 observations [2] suggest a continuing or accelerating trend of increased parasite activity. Vets said owners should check pets daily after they spend time outdoors to identify and remove ticks before they can transmit diseases.
“Veterinarians say peak tick season is underway.”
The shift in tick activity reflects a broader environmental trend where warming climates are expanding the active windows for zoonotic parasites. When pests emerge earlier than historical norms, it creates a 'protection gap' where pets are exposed before owners apply seasonal medications. This necessitates a transition from seasonal to year-round preventative care to mitigate the risk of tick-borne diseases across North America.
