Quick answer
Tick season on Delmarva runs roughly April through November, with the most dangerous window being May through July when tiny nymphs are hardest to spot. After any wooded, brushy, or tall-grass outing, do a full body check within two hours, shower, and toss your clothes in a hot dryer for 10 minutes. If you find an attached tick, remove it with fine-tip tweezers, save it, and watch the bite for a month.
When is tick season on Delmarva?
Ticks are active any time the ground is unfrozen, but risk concentrates in two big windows: late spring through midsummer (nymph season) and early through late fall (adult season).
March – April
Adult black-legged ticks become active on warm afternoons; nymphs start emerging by late April.
May – July
Peak nymph season - the most dangerous window for Lyme exposure because nymphs are tiny and easy to miss.
July – August
Lone star ticks dominate brushy areas. Aggressive and fast-moving; bites can trigger alpha-gal sensitivity.
September – November
Adult black-legged ticks return in force. Fall yard cleanup is a high-exposure activity.
December – February
Risk drops but isn't zero - adult ticks quest on any day above ~40°F.
Where do most Delmarva tick encounters happen?
- Walking wooded trails at Trap Pond, Killens Pond, Cape Henlopen, or Pocomoke State Forest.
- Cutting through tall grass, brushy field edges, or marsh-adjacent paths.
- Yard cleanup - raking leaves, hauling brush, working along the wood line.
- Dog walks through grassy shoulders, then close contact with the dog at home.
- Sitting or kneeling in leaf litter (gardening, mulching, hunting setups).
- Tent camping or cabin stays where gear sits on the ground for hours.
What does a tick bite look like?
- A small red bump at the bite site, often unnoticed until itching starts a day or two later.
- An expanding circular or oval rash 3–30 days later - the classic 'bull's-eye' is one pattern, but many Lyme rashes are uniformly red.
- A flat red ring with a clear center (lone star tick) sometimes called STARI.
- Itchy welt at the bite that lingers for one to two weeks even with no infection.
- Multiple bites in one outing - adults often pick up several nymphs from a single brush against tall grass.
Most tick bites do not transmit disease. The risk goes up with how long the tick was attached - generally above 24 hours for Lyme.
What should I do right after finding a tick?
- 1Don't panic - most bites don't transmit disease, especially if the tick is removed quickly.
- 2Note the date and roughly how long the tick may have been attached.
- 3Remove the tick using the steps below. Don't squeeze the body or use folk remedies.
- 4Save the tick in a sealable bag or stuck to clear tape, labeled with the date.
- 5Wash the bite, mark the spot in a phone photo, and watch it for 30 days.
- 6Check the rest of your body - ticks travel in pairs more often than people expect.
How do I remove a tick safely?
- 1Use fine-tip tweezers or a dedicated tick-removal tool. Don't crush or twist with fingernails.
- 2Grasp the tick as close to the skin as possible - at the mouthparts, not the body.
- 3Pull straight up with steady, even pressure. Don't jerk, twist, or yank sideways.
- 4If a piece of mouthpart breaks off, leave it - your body will work it out. Don't dig.
- 5Clean the bite with soap and water, then rubbing alcohol or an antiseptic.
- 6Save the tick in a sealable bag or piece of tape with the date. If symptoms develop, your clinician can use it for ID.
- 7Don't use petroleum jelly, nail polish, matches, or essential oils - these don't work and can make the tick regurgitate into the wound.
When should a tick bite see a doctor?
Most tick bites resolve on their own. A short list of warning signs means you should stop self-treating and contact a clinician.
- Expanding red rash at or away from the bite site, days to weeks later.
- Fever, chills, body aches, headache, or fatigue within a month of a bite.
- Joint pain or swelling, especially in the knees.
- Facial drooping or nerve symptoms.
- A new meat allergy after a lone star tick bite (alpha-gal syndrome).
- Tick was attached more than 24 hours and you live in a high-Lyme area - ask about prophylaxis.
How do I prevent tick bites for people, kids, and pets?
For adults
- Picaridin or DEET on skin; permethrin on clothing and shoes.
- Tuck pants into socks for trail and yard work.
- Shower and full-body check within two hours of coming inside.
- Run worn clothes in a hot dryer for 10 minutes.
For kids
- Permethrin-treated outer layers; picaridin on exposed skin.
- Make tick checks part of bath time after any outside play.
- Pay attention to the scalp, behind ears, and waistband.
- Light-colored clothing makes ticks easier to spot.
For pets
- Year-round vet-prescribed tick preventive (oral or topical).
- Run hands through coat after every walk - focus on ears, neck, armpits, between toes.
- Keep grass short and clear leaf litter near the house.
- Consider a tick collar for dogs spending time in fields and woods.

Why are ticks so common on the Eastern Shore?
Ticks live almost everywhere on the Peninsula - the wooded trails at Trap Pond, Pocomoke, and Cape Henlopen; the tall-grass shoulders along every back road; the brush lines behind farms and subdivisions; the campgrounds that fill up every weekend; and the marsh-adjacent paths where deer paths cross human ones. Dog walks and fall yard cleanup are two of the most reliable ways Delmarva families pick up ticks. Build the habit of a quick check at the door, a shower within two hours, and a 10-minute hot dryer cycle for the day's clothes.

Frequently asked questions
- When is tick season on the Eastern Shore?
- Ticks are active any month above freezing. Peak activity runs April through November, with lone star ticks especially aggressive in the southern Delmarva woods.
- What is the right way to remove a tick?
- Use fine-tipped tweezers to grasp the tick as close to the skin as possible. Pull straight up with steady pressure. Clean the area, save the tick, and note the date.
- How long does a tick need to attach to transmit Lyme?
- Most studies suggest 24 to 48 hours of attachment. Daily tick checks and prompt removal substantially lower the risk.
- Does permethrin on clothing actually work?
- Yes, and it is the single most effective tick precaution. Treated clothing kills ticks on contact and remains effective for several wash cycles.
