If you have shopped for bug spray in Canada, you have probably seen the word icaridin on the label and wondered how it fits next to the more familiar DEET. Here is the short version. Icaridin is a well-studied insect repellent active that Health Canada recognizes for protection against mosquitoes and ticks. It is the same ingredient that shoppers in the United States know as picaridin. Different name, same molecule.
This guide explains what icaridin is, how it works, the concentrations you will see on Canadian shelves, the age guidance to keep in mind, and how it compares to DEET. We will also cover where a plant-based option like oil of lemon eucalyptus, and the PMD it contains, fits for people who want protection without either icaridin or DEET.
The quick answer
Icaridin (also spelled picaridin, and sometimes listed by its chemical name hydroxyethyl isobutyl piperidine carboxylate) is a synthetic repellent modeled loosely on a compound found in black pepper plants. Health Canada lists it as an effective active ingredient against mosquitoes and ticks, alongside DEET. The US Centers for Disease Control and Prevention (CDC) recognizes the same active under the name picaridin. In Canada you will commonly see it at concentrations such as 20 percent. It tends to feel light on skin, is generally low-odor, and does not damage plastics and synthetic fabrics the way DEET can.
If you would rather skip synthetics entirely, oil of lemon eucalyptus (OLE) and its active compound PMD are the CDC-recognized plant-based route. That is the category The Superbloc formulates in, with an 8 percent PMD active derived from lemon eucalyptus.
Icaridin vs picaridin: why two names for one ingredient
This trips up a lot of Canadian shoppers, so it is worth stating plainly. Icaridin and picaridin are two names for the exact same active ingredient. There is no difference in the chemistry, the protection, or the safety profile between them.
The naming split is mostly regional. Icaridin is the name used in Canada, Europe, and much of the rest of the world. Picaridin is the name that took hold in the United States and Australia. So a product sold in Ontario might say icaridin while a nearly identical product sold in New York says picaridin. Same molecule, different label.
If you have read American guides or CDC materials that reference picaridin, everything they say about it applies to the icaridin you find in Canada. When you cross-shop reviews and testing from both countries, treat the two words as interchangeable.
How icaridin works
Icaridin does not kill mosquitoes or ticks. It works by making you harder to find and less appealing to bite. Mosquitoes locate people largely through the carbon dioxide we exhale, body heat, and certain scent compounds on our skin. Icaridin appears to interfere with the receptors insects use to home in on those cues, so treated skin reads as a poor target. The insect is more likely to move on rather than land and bite.
Because it works at the surface, even coverage matters more than heavy application. A thin, complete layer over exposed skin generally outperforms a thick patch that leaves gaps.
Common icaridin concentrations in Canada
Concentration affects how long a repellent keeps working, not how strongly it repels in the first minutes. A higher percentage usually means a longer window before you need to reapply, up to a point of diminishing returns.
On Canadian shelves you will typically see icaridin around 20 percent, which many products position for several hours of protection against mosquitoes and ticks. Lower-percentage formulas exist and are often aimed at shorter outings or lighter exposure.
Because product claims and approved ranges are set by Health Canada and can change, always read the specific product label for its stated protection time and reapplication instructions rather than assuming a number from a general guide. Please verify current approved concentration ranges directly on the label.
Age guidance for icaridin
Age guidance is one of the most searched questions about any repellent, and it is exactly the kind of detail where you should follow the product label and Health Canada guidance rather than a rule of thumb.
In general, Health Canada provides separate guidance for different repellent actives and for different age groups, including specific direction for infants and young children. Icaridin products carry their own minimum-age and application instructions on the label. Before using any repellent on a child, check that the product is approved for that age and follow the stated limits on how often to reapply.
This article does not replace that label. Treat the packaging and Health Canada as the source of truth for who can use a given product and how.
Icaridin vs DEET
DEET is the active most Canadians grew up with, and it remains one of the most studied repellents in the world. Both DEET and icaridin are recognized by Health Canada and the CDC as effective against mosquitoes and ticks. The practical differences come down to feel and materials.
DEET can feel oily and carries a stronger odor, and at higher concentrations it can degrade certain plastics, synthetic fabrics, and coated gear. Icaridin tends to feel lighter, is generally lower in odor, and is friendlier to synthetic materials, which is why many people who dislike the DEET experience switch to it.
Neither is a plant-based option. Both are synthetics. For a fuller side-by-side, see our companion guide on how picaridin and DEET compare. And if you are wondering about the regulatory status of DEET north of the border, we cover that separately in is DEET banned in Canada.
Comparison table: icaridin vs DEET vs OLE/PMD
| Feature | Icaridin (picaridin) | DEET | OLE / PMD |
|---|---|---|---|

Values above are general and vary by product. Confirm protection times, concentrations, and age limits on the specific label.
Is icaridin safe?
When used as directed, icaridin is regarded by Health Canada and the CDC as an effective repellent option, which is why it sits alongside DEET in their guidance. As with any repellent, the safety picture depends on using the product the way its label instructs, applying an even layer to exposed skin, avoiding eyes and broken skin, and following the reapplication and age directions.
We are a repellent brand, not a medical authority, so we point you to Health Canada and the CDC for the regulatory and health specifics, and to the individual product label for how to use it correctly. If you have a specific medical concern, especially for infants or during pregnancy, talk to a healthcare professional.
Where plant-based OLE and PMD fit
Icaridin is a strong option, but it is still a synthetic, and plenty of people are specifically looking for a plant-based repellent that is both DEET-free and icaridin-free. That is the space oil of lemon eucalyptus occupies.
OLE is derived from the lemon eucalyptus tree, and its active repellent compound is PMD. Importantly, PMD is the one plant-based active the CDC recognizes in the same breath as DEET and picaridin. It is not folk wisdom. It is a botanically sourced active with real testing behind it.
The Superbloc formulates in this category. Our Bloc Off Spray uses 8 percent PMD from lemon eucalyptus as its active. It is alcohol-free and water-based, which is part of why it feels light rather than harsh going on. In our own lab testing it held up for 6 or more hours, and our brand testing supports use from 6 months of age. Those last two points are based on The Superbloc's testing, and we call that out plainly rather than dressing it up as a regulatory position.
If you want to understand the ingredient itself before you choose, our explainer on lemon eucalyptus mosquito repellent goes deeper on how OLE and PMD work. And for households covering a range of ages and activities, the Family Mosquito Protection Pack bundles the spray with our other formats.
How to choose between them
There is no single right answer, and the honest framing is about fit rather than one option beating the others.
Choose icaridin if you want a synthetic that feels lighter and lower-odor than DEET and is gentler on gear, and you are comfortable with a synthetic active. Choose DEET if you prefer the most heavily studied conventional option and do not mind the feel. Choose OLE and PMD if your priority is a plant-based, DEET-free and icaridin-free active that is still recognized by the CDC, and you want a water-based formula that feels light.
Whatever you pick, apply an even layer, follow the label for timing and age, and reapply as directed. Coverage and correct use matter more than any single number on the front of the bottle.
Frequently asked questions
Is icaridin the same as picaridin? Yes. Icaridin and picaridin are two names for the identical active ingredient. Icaridin is the name used in Canada and much of the world, while picaridin is used in the United States. There is no difference in the chemistry or the protection.
Does Health Canada approve icaridin? Health Canada recognizes icaridin as an effective active ingredient for repelling mosquitoes and ticks, alongside DEET. For the specific approved concentrations, age guidance, and protection claims, follow the individual product label, which reflects Health Canada's current direction.
What concentration of icaridin should I look for? In Canada you will commonly see icaridin around 20 percent, which is generally positioned for several hours of protection. Higher concentrations extend the reapplication window rather than making the repellent stronger. Always confirm the protection time and reapplication instructions on the label.
Is icaridin better than DEET? Neither is strictly better. Both are recognized by Health Canada and the CDC as effective. Icaridin tends to feel lighter, is lower in odor, and is gentler on plastics and synthetic fabrics, which is why many people prefer it. DEET is the more heavily studied conventional option.
Is there a plant-based alternative to both icaridin and DEET? Yes. Oil of lemon eucalyptus and its active PMD are plant-based and CDC-recognized. The Superbloc's Bloc Off Spray uses 8 percent PMD from lemon eucalyptus, is alcohol-free and water-based, and in our lab testing lasted 6 or more hours.
