The Superbloc vs OFF! Botanicals: Which Plant-Based Bug Spray Wins?

Shopping for a plant-based mosquito repellent? You've probably seen OFF! Botanicals on store shelves and The Superbloc online. Both promise DEET-free protection. But how do they actually compare?

We're breaking down ingredients, protection time, scent, skin feel, kid safety, and value side by side — everything you need to choose the right one for your family.

The Brands at a Glance

OFF! Botanicals is a line extension from SC Johnson's OFF! brand (making insect repellents since 1957). The Botanicals line is their plant-based alternative to flagship DEET products. Widely available at drugstores and grocery stores across the US.

The Superbloc is the first brand dedicated entirely to plant-based bug solutions — covering both personal care (sprays, wipes) and home products (moth and odor defense tags). Women-founded, stocked at Anthropologie, and featured in Goop and Harper's Bazaar. Available on thesuperbloc.com, Amazon, and select retailers.

Active Ingredients: What's Doing the Work?

OFF! Botanicals uses 2% p-Menthane-3,8-diol (PMD) derived from pine oil extract. The product is EPA-registered and marketed for up to 2 hours of mosquito protection.

The Superbloc uses 8% PMD as the primary active ingredient, supported by 1% eucalyptus citriodora oil, 0.5% cedarwood essential oil, and 0.5% copaiba essential oil. Classified as a 25(b) exempt minimum risk pesticide under FIFRA. Lab-tested for 6+ hours of protection.

Both products rely on PMD as the repellent workhorse — but at 4× the concentration in The Superbloc. That concentration difference directly impacts how long protection lasts.

Head-to-Head Comparison

Protection Time: How Long Do They Last?

OFF! Botanicals: Up to 2 hours. Adequate for a quick errand, but a full afternoon at the park means 2-3 reapplications.

The Superbloc: 6+ hours lab-tested. The higher PMD concentration and supporting botanical oils create a longer-lasting barrier. One application covers an entire evening outdoors.

For a family spending 4 hours at an outdoor barbecue, that's the difference between one application vs three.

Scent: Would You Actually Want to Wear This?

OFF! Botanicals has a mild, lightly herbal scent that fades quickly — inoffensive but forgettable.

The Superbloc was designed with scent as a priority. The Bloc Off line features lemon eucalyptus and cedarwood notes that read more like a fragrance than a bug spray. The Bloc & Chill line adds peppermint for a fresh cooling variation. Press coverage in Goop and Harper's Bazaar has specifically called out the scent as a standout feature.

If daily wearability matters to you — applying before work, dinner, or a date — this category has a clear winner.

Skin Feel & Formula

OFF! Botanicals applies as a light mist, absorbs reasonably quickly, but adds no moisturizing or skincare benefit. It's a repellent, full stop.

The Superbloc takes a skincare-forward approach. The base includes hydrogenated castor oil (8%), glycerin (1%), aloe barbadensis leaf juice (1%), and chamomile extract (0.5%) — ingredients you'd expect in a moisturizer. It's alcohol-free, so there's no stinging or drying effect. The result is a product that actually feels good on skin, which makes a real difference when you're applying it every day.

Kid Safety

OFF! Botanicals: Not for children under 3 years old (standard for EPA-registered OLE/PMD products).

The Superbloc: Safe for children 6 months and older. The lower PMD concentration (8%) combined with an alcohol-free, skin-soothing formula is designed for sensitive young skin.

For families with babies and toddlers, this is a meaningful 2.5-year difference in when your child can start using effective plant-based protection. Learn more in our guide to DEET-free repellent for babies and toddlers.

The Verdict

Choose OFF! Botanicals if: You want a quick, affordable plant-based option for short outdoor stints and prefer buying at your local drugstore. It's a fine entry point into DEET-free repellents.

Choose The Superbloc if: You want longer-lasting protection (6+ hours vs 2), a product that feels and smells good enough for daily use, a formula gentle enough for babies 6 months+, skincare ingredients that actually nourish your skin, and a brand that extends plant-based defense into your home with the Home Series.

Frequently Asked Questions

Do The Superbloc and OFF! Botanicals use the same active ingredient?

Both rely on PMD (para-menthane-3,8-diol), the plant-based compound from lemon eucalyptus recognized by the CDC as effective against mosquitoes. The critical difference is concentration: The Superbloc uses 8% PMD while OFF! Botanicals uses 2% PMD. This 4× concentration gap directly impacts protection duration — 6+ hours vs approximately 2 hours per application. The Superbloc also includes supporting botanical oils (cedarwood, eucalyptus citriodora, copaiba) that complement the PMD for broader repellent coverage.

Can I use OFF! Botanicals on my toddler?

OFF! Botanicals' label states it should not be used on children under 3 years old, which is the standard age restriction for EPA-registered OLE products at that concentration. For families with younger children, The Superbloc's Bloc Off line is formulated for children 6 months and older, using a lower 8% PMD concentration in an alcohol-free base with skin-soothing aloe vera and chamomile. This 2.5-year age advantage is one of the most significant differences between these products.

Which plant-based mosquito repellent smells better?

The Superbloc was designed with scent as a priority. The lemon eucalyptus and cedarwood blend has been specifically featured in Goop and Harper's Bazaar for its wearable, elevated fragrance. OFF! Botanicals has a mild herbal scent that's inoffensive but fades quickly and isn't particularly memorable. For a product you'll actually want to apply daily — before work, dinner, or outdoor activities — The Superbloc's scent is in a different category entirely.

Is The Superbloc worth the higher price vs OFF! Botanicals?

When you compare cost per hour of protection, the math shifts significantly. OFF! Botanicals at $8 provides ~2 hours per application. The Superbloc at $28 for a 2-pack provides 6+ hours per application, meaning fewer reapplications and less product used per day. Add the skincare-grade formula (aloe vera, chamomile, glycerin — you'd pay for these in a separate moisturizer), the younger age suitability (6 months+ vs 3 years+), and the alcohol-free base that's gentler on sensitive skin, and the value proposition is strong for families using repellent regularly through mosquito season.
