When does tick season start in CT?

Tick season is technically all-year-round, as ticks don’t really go anywhere when the weather is cold. During the winter months, they burrow in deep leaves and sometimes go dormant, if it’s cold enough.

Ticks are most prevalent starting around April when the weather starts to warm up. People generally refer to this time as “tick season”

This is when the nymphs (immature ticks) become active and mature ticks begin to feed again after the long Connecticut winter.

The 2021/2022 winter season went on a bit longer than in previous years. So, the ticks are out in full force this spring – hungrier than we’ve gotten used to.

How long is tick season in Connecticut?

So, when is tick season going to end?

The answer to this question really depends on this year’s weather. However, tick season in Connecticut typically ends in late October or mid-November.

Come the fall months, though, it’s not time to let down your guard on tick bite prevention and tick-checks for yourself and your family.

While spring is when nymphs are most active, Fall is when the mature ticks are most active.

So, now that you know a bit about what to expect from these disgusting little Connecticut arachnids, what can be done to prevent getting a tick bite?
