This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.

What this guide covers

Four active substances have real published protection times — DEET, icaridin, IR3535 and PMD — and the page gives the concentration-to-hours table for each, against mosquitoes and against ticks separately, because they differ.

Item pages cover the products with no effect (ultrasound, bracelets, vitamin B), permethrin-treated clothing, age and pregnancy limits as they appear on the authorised label, how to check a product in the Estonian and Finnish biocide registers, the sunscreen-first ordering and the SPF loss, nets and mesh sizes, Lapland midges, and tick-removal tools and technique. ~15 pages.

How to use it

Use Insect and tick repellents that work to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.

The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Search vocabulary in four languages

Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

Evidence and provenance

The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.

Source: Regulation (EU) 528/2012 and the ECHA active-substance list (open), Terviseamet biocide register and Tukes biosidirekisteri (official), CDC and US EPA repellent guidance (public domain), published protection-time trials (cited), ECDC tick distribution maps (open). · checked 2026-09-09

Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
