What to spray to repel ticks? - briefly
Apply a 20 % permethrin spray to clothing and gear; for exposed skin, use a lotion containing 0.5 %–1 % DEET, 10 %–20 % picaridin, or 20 % IR3535.
What to spray to repel ticks? - in detail
Effective tick deterrents fall into two categories: synthetic chemicals and plant‑derived compounds. Both groups require proper concentration, coverage, and re‑application to maintain protection.
Synthetic repellents
- DEET (N,N‑diethyl‑m‑toluamide) – concentrations of 20‑30 % repel ticks for up to 6 hours; higher percentages extend protection but increase skin irritation risk.
- Permethrin – a contact insecticide applied to clothing and gear, not directly to skin; 0.5 % solution prevents attachment for several weeks after laundering.
- Picaridin (KBR‑3023) – 10‑20 % formulations provide 8‑10 hours of efficacy, comparable to DEET with lower odor and reduced skin sensitivity.
- IR3535 – 20 % solution offers 4‑6 hours of protection; useful for individuals sensitive to DEET.
Plant‑derived repellents
- Citronella oil – 10‑20 % concentration yields 2‑3 hours of tick deterrence; effectiveness diminishes rapidly in high humidity.
- Lemon eucalyptus (PMD) – 30 % formulation protects for 4‑6 hours, comparable to low‑concentration DEET.
- Geraniol and lemongrass – 5‑10 % mixtures achieve 1‑2 hours of activity; best used in combination with synthetic agents for extended coverage.
- Rose geranium oil – limited data suggest 5‑15 % solutions provide short‑term repellent effect; not recommended as sole protection.
Application guidelines
- Clean skin or fabric before spraying to ensure adhesion.
- Apply evenly, covering all exposed areas; for clothing, treat both interior and exterior surfaces.
- Allow the product to dry before dressing to avoid transfer.
- Re‑apply according to label‑specified intervals, typically every 4‑6 hours for skin sprays and after every 5–6 washes for permethrin‑treated garments.
- Store containers in a cool, dark place to preserve chemical stability.
Safety considerations
- Avoid applying DEET or picaridin to infants under two months; use only pediatric‑approved formulations.
- Do not apply permethrin directly to skin; wash treated clothing before wear.
- Test essential‑oil blends on a small skin patch to detect allergic reactions.
- Follow occupational exposure limits when handling concentrated chemicals in bulk.
Combining a synthetic skin repellent with permethrin‑treated clothing maximizes protection, covering both direct contact and environmental exposure. Selecting the appropriate product depends on activity duration, skin sensitivity, and the need for long‑term garment treatment.
