How long does the protection last and when should I reapply?

The product is labelled for up to 8 hours of protection against mosquitoes and ticks under typical conditions. In practice, duration depends on temperature, humidity, how much you sweat, and whether you swim or towel off. DEET and Citriodiol both gradually evaporate from the skin surface, so protection declines over time rather than stopping abruptly.

Reapply if you notice insects landing on treated skin again, after swimming or heavy sweating, or after towelling dry. Because this is a 30% DEET lotion, avoid unnecessary frequent reapplication — use the minimum needed for your exposure time. For a full day outdoors, a morning application plus one top-up in the afternoon is often sufficient. Do not exceed the number of applications recommended on the packaging (typically 1–2 times per day for 30% DEET products).

Apply as the final step before going outside, on dry skin. If you also use sunscreen, apply sunscreen first, let it absorb, then apply the repellent lotion. Sunscreen may need more frequent reapplication than the repellent; in that case, reapply sunscreen over the repellent if needed, but avoid layering repellent more often than directed.
