Ticks are most active in Virginia from April through September, with peak activity occurring in June and July when both nymph and adult ticks are seeking hosts.
If you are planning outdoor activities, you might be wondering when to start worrying about tick prevention. You might be surprised, however, at just how early ticks can become active—and how long they can stick around in Fredericksburg.
Once temperatures consistently reach the mid-40s, ticks emerge from winter dormancy and start looking for blood meals. In Fredericksburg, this typically happens around early to mid-April. From that point onward, tick encounters become increasingly common as spring progresses into summer.
Tick dangers are at their highest in June and July. Nymph-stage blacklegged ticks, which are the primary carriers of Lyme disease, are most active during late spring and early summer. These tiny ticks, roughly the size of poppy seeds, are responsible for most Lyme disease transmission because they’re small enough that people often don’t notice them. About one in seven ticks in Virginia carry Lyme disease bacteria, and nymphs are extra worrisome because of their small size and abundance during this peak period.
To make matters worse, adult ticks are also active during summer months. Deer ticks, dog ticks, and lone star ticks all overlap during June and July, meaning there is a threat window where different ticks of different species are all active at once, posing different disease risks.
Tick activity doesn’t end as the temperatures cool down, though. Ticks remain active through September and can even resurge in October during warm fall days. Adult blacklegged ticks have a second, smaller peak in autumn as they search for final blood meals before winter. In Virginia’s relatively mild climate, you could see ticks on any warm day above 45°F, even in winter months.
This extended tick season means that doing occasional tick checks after spring hikes isn’t enough. Families need to be vigilant from April to September at a minimum, checking kids and pets after outdoor play, wearing protective clothing during hikes, and inspecting yards for tick-friendly habitats like tall grass, leaf litter, and wood piles.
If you live in Fredericksburg and you’re looking for season-long protection, Mosquito Squad of Fredericksburg's tick control program can help. Barrier treatments can reduce tick populations by up to 85-90% throughout Virginia's active season. This is because professional inspections find high-risk areas on your property where ticks are most likely to be a problem, including yard edges, wooded borders, and areas around wood piles. Regular treatments starting in early spring and continuing through fall create consistent protection during peak months and beyond.
