LymeHQ · Prevention Reference
Not getting bitten is the only intervention that works every time — and when it fails, how you take the tick off measurably changes your risk. Repellents compared honestly, and the removal technique that does not make things worse.
Repellent active ingredients, the treated-clothing guidance, and the tick-removal procedure. A clinically-informed reviewer has not yet signed this off, and it stays marked until one does.
This section is first on purpose. Most people arrive here mid-problem, and removal technique is where avoidable harm happens.
Use fine-tipped tweezers, not fingers
Grasp the tick as close to the skin as you can get. Pointed tweezers work far better than the flat household kind, which tend to squeeze the body.
Pull straight up, slow and steady
Even pressure, straight out. Do not twist or jerk — that is what breaks the mouthparts off in the skin.
If mouthparts stay behind, leave them
Try to lift them out with the tweezers, and if they will not come, leave them and let the skin heal. Digging around causes more trauma than the fragment does.
Clean the bite and your hands
Soap and water, or rubbing alcohol. Nothing more complicated is needed.
Save the tick and write down the date
Sealed bag, a scrap of damp paper towel, the date and where on your body it was attached. It can be tested, and the date is what tells a clinician whether a later blood test means anything.
Nymphs peak exactly when people are outside most — late spring into summer.
Northeast and upper Midwest pattern. Timing shifts by region and by year, so read the months as orientation rather than as a local calendar — a month outside a stage's range is not a month with no ticks.
Life-stage seasonality for the blacklegged tick (Ixodes scapularis) in the Northeast and upper Midwest: US Centers for Disease Control and Prevention. Months are approximate and shift by region and by year; nothing on this drawing is a measured quantity.
Nymphs are out when people are, and small enough to miss entirely.
Silhouettes for scale only — not an identification aid. Size varies by species and sex, and a tick that has already fed is larger than any of these.
Life stages and the poppy-seed / sesame-seed size comparisons: US Centers for Disease Control and Prevention, tick life cycle and tick identification. The three silhouettes are drawn to scale against one another; no absolute measurement is shown.
A routine C6 antibody test at the annual vet visit.
A dog and the people it lives with walk the same ground. A positive result is a fact about that ground, arrived at without anyone having had to notice anything.
Nothing here is a result for a person. What it gives you is one sentence worth saying out loud at your next appointment.
It says nothing about whether any person is infected. Dogs are tested yearly, stay close to home, and cannot hide symptoms.
Orientation only. Nothing on this drawing is a measurement — there is no rate here, no timeframe and no dose. It says what the alert itself says: where ticks are, never what anyone has. We test the real alert against that same limit on every build.
Rated on the prototype's five-point scale. Effectiveness varies with concentration and how thoroughly it is applied — the best repellent is the one you will actually use properly.
CDC Recommended · On Skin
Effectiveness
An active ingredient CDC lists for tick and mosquito repellents. At 20–30% concentration, provides 6–8 hours of protection. Safe for adults, children 2+ months, and during pregnancy.
CDC Recommended · On Skin
Effectiveness
Equal effectiveness to DEET with better aesthetics. Odorless, non-greasy, won't damage plastics or fabrics. The preferred choice for children and anyone who dislikes DEET's feel. Widely used in Europe and increasingly recommended by pediatricians.
CDC Recommended · Plant-Based
Effectiveness
The only plant-derived repellent CDC recommends for ticks. OLE (also called PMD — the synthesized form) provides 6+ hours of protection. Important: this is NOT the same as pure lemon eucalyptus essential oil, which is unformulated and not registered with EPA.
CDC Recommended · On Skin
Effectiveness
A synthetic repellent that's been used in Europe for 20+ years. Effective and gentle — commonly found in sunscreen-repellent combination products. Slightly less potent than DEET or Picaridin for tick-specific protection but widely considered safe.
On Clothing Only — NOT Skin
Effectiveness
Kills ticks on contact within seconds. Apply to boots, socks, pants, and tent fabric. Let dry completely before wearing (hang overnight in garage). Effective insecticide — keep away from cats until dry.
Pretreated · Long Duration
Effectiveness
Clothing treated with permethrin at the factory holds its protection for 70+ washes; spray-on treatment lasts around 6. It costs more upfront and less per wash.
No cost · Immediate effect
Effectiveness
Smart clothing choices significantly reduce tick access before you even open a repellent bottle.
Post-Exposure · Free · Highly Effective
Effectiveness
One of the most underused and most effective tick-killing methods. Ticks are highly susceptible to desiccation (drying out). Tumble drying on high heat kills ticks on clothing before they can crawl off to find you.
Permanent · High Impact · No Chemicals
Effectiveness
Modifying your yard to make it inhospitable to ticks provides lasting protection with no ongoing cost or chemical exposure.
Acaricide · Most Effective Chemical Option
Effectiveness
Kills ticks on contact and creates a barrier lasting up to 40 days. A 2.5% permethrin concentrate with a hose-end sprayer covers 10,000 sq ft. Focus on the transition zone between lawn and woods — where 80%+ of tick encounters happen.
Commercial Acaricide Service
Effectiveness
Professional pest control using commercial-grade acaricides reduces nymphal tick density by 80–90% in treated areas per UW study. One treatment persists approximately 4 weeks. Worth it for high-exposure properties.
Reduced Toxicity · Moderate Effectiveness
Effectiveness
For households that prefer to minimize pesticide use, especially around children and pets. Less effective than permethrin but better than nothing in the right areas.
Prescription · Dogs Only · Fast Kill
Effectiveness
Most veterinarians' first-choice recommendation for dogs. Oral chewables that kill ticks within hours of attachment — before Lyme transmission can occur. No skin residue, fully systemic, not washed off by swimming or bathing.
Dogs & Cats · Repels & Kills · 8 Months
Effectiveness
The longest-lasting single-application option — 8 months of continuous protection. Unlike oral preventatives, the Seresto collar repels ticks and prevents attachment by releasing imidacloprid and flumethrin across the coat. Must maintain skin contact to work.
Dogs Only · Repels & Prevents Attachment
Effectiveness
Monthly spot-on topicals containing permethrin that repel and prevent tick attachment — like the Seresto collar but applied monthly to the skin.
Detection · Sentinel Signal · Annual Vet Visit
Your dog is a household sentinel. The IDEXX 4Dx Plus test screens for Lyme (C6 antibody), Ehrlichia, Anaplasmosis, and Heartworm in a single blood test. A positive C6 result triggers a LymeHQ household alert — and is a strong signal that all household members should consider testing.
Within 2 Hours of Coming Inside
Effectiveness
The CDC-recommended routine that catches ticks before they attach or early enough to prevent transmission.
Immediately on Discovery
How you remove a tick matters. Incorrect removal can squeeze pathogens into the bite site and increase infection risk.
Discuss With Your Doctor Within 72 Hours
After Any Tick Bite
Knowing what pathogens the tick carries informs whether prophylactic treatment is urgent and what to watch for.
