Here are some of the key reasons behind these predictions:
| One major factor is the winter. Although it may seem like cold weather would reduce tick populations, it often does the opposite. Snow and leaf cover act as insulation, allowing more ticks to survive until spring. This means larger populations are already in place as temperatures rise.
Warmer weather is another key reason. In recent years, New York has experienced milder winters and earlier springs. Ticks become active when temperatures rise above about 40°F, so warmer conditions allow them to emerge earlier and stay active longer into the fall. Instead of a short season, tick activity can now stretch from early spring through late autumn. New York is also considered a hotspot for tick-borne diseases. The state consistently reports high rates of Lyme disease, especially in regions like Long Island and the Hudson Valley. Many ticks in the area carry not only Lyme disease but also other infections such as babesiosis and anaplasmosis. Some ticks can even carry multiple diseases at once, increasing the risk of complications. Another reason for the increase is the abundance of host animals. Deer and white-footed mice, which ticks rely on for feeding and reproduction, are common throughout suburban and wooded areas of New York. As these animal populations thrive, so do tick populations. Experts are particularly concerned about nymph ticks, which are most active from late spring through mid-summer. These ticks are very small—often no bigger than a poppy seed—and are responsible for most disease transmission because they are difficult to detect. In short, the concern about a “bad tick season” comes down to a combination of mild winter conditions, longer warm periods, high disease rates, and favorable environments for ticks and their host animals. Together, these factors are expected to make ticks more active and more widespread across the region this year. |
