This guide compares mosquito repellent options and provides safety recommendations. Key considerations include:
General Safety Tips
- Follow product labels strictly to avoid overuse.
- Avoid applying sunscreen over repellent, as this increases chemical absorption.
- Apply repellent only to exposed skin (avoid face, hands, and mucous membranes). Wash treated skin after returning indoors.
- Children are more vulnerable to toxicity; avoid letting them apply repellent themselves.
- DEET concentrations above 30% are not recommended for children or infants under 2 months.
Repellent Options
- DEET:
- Effective for 2-12 hours depending on concentration (30% is optimal).
- Avoid concentrations over 30% for children.
-
Damages synthetic fabrics (use cotton, wool, or nylon).
-
Picaridin:
- Similar effectiveness to DEET with fewer long-term studies.
-
Safer for children than DEET but same application precautions apply.
-
Oil of Lemon Eucalyptus:
- Effective for ~2 hours.
-
Not recommended for children under 3 or pregnant/nursing individuals.
-
IR3535:
- Available in 7.5-20% concentrations.
-
Safe for use during pregnancy when applied as directed.
-
Permethrin:
- Apply to clothing only (not skin).
- Effective for 6-60 washes depending on application method.
Additional Notes
- Natural alternatives (soybean oil, citronella) may offer limited protection (<1 hour).
- Clothing barriers (long sleeves, socks, hats) should be used with repellents.
- Choose products based on local mosquito-borne disease risks and personal sensitivity.
