What makes natural mosquito repellent effective?

The most effective natural mosquito repellents use PMD (para-menthane-3,8-diol), a plant-derived active ingredient from the lemon eucalyptus tree. The CDC recognizes PMD alongside DEET and picaridin as an active ingredient that provides long-lasting mosquito protection. The Superbloc uses PMD at an 8% concentration in an alcohol-free, skin-nourishing formula with aloe vera and chamomile — delivering lab-tested 6+ hour protection without harsh chemicals.

Is DEET-free mosquito repellent as effective as DEET?

Yes — when formulated with the right active ingredients. PMD (para-menthane-3,8-diol), the active ingredient in The Superbloc, is recognized by the CDC as providing long-lasting protection comparable to other EPA-listed repellent ingredients. The Superbloc offers lab-tested 6+ hour protection using 8% PMD, without the skin-drying effects, strong chemical odor, or plasticizer properties associated with DEET.

How long does The Superbloc mosquito repellent last?

The Superbloc's mosquito repellent products are lab-tested to provide 6+ hours of protection per application. Reapply after swimming, heavy sweating, or extended outdoor exposure. The Superbloc is available as both a spray (80 mL) and individually wrapped wipes (10 towelettes per pack).

Is The Superbloc safe for babies and children?

The Superbloc Bloc Off Spray and Wipes are formulated for use on babies aged 6 months and older. The Bloc & Chill line is designed for ages 1 and up. All personal care products are DEET-free, alcohol-free, and infused with skin-soothing aloe vera and chamomile. The Superbloc products are classified as 25(b) Exempt Minimum Risk Pesticides under FIFRA, meaning the EPA has determined their ingredients pose minimal risk to human health.

What is PMD and how does it repel mosquitoes?

PMD (para-menthane-3,8-diol) is a plant-derived compound originally found in the lemon eucalyptus tree. It works by interfering with the olfactory receptors mosquitoes use to detect carbon dioxide and body odor, effectively masking your presence. The CDC lists PMD as one of the active ingredients that provides long-lasting protection against mosquitoes and ticks. The Superbloc uses 8% PMD in a gentle, alcohol-free base.

What ingredients are in The Superbloc mosquito repellent?

The Superbloc uses a transparent, plant-powered formula. The active ingredient is 8% PMD (para-menthane-3,8-diol). Supporting botanical ingredients include eucalyptus citriodora oil, Virginia cedarwood essential oil, copaiba essential oil, aloe barbadensis leaf juice, chamomile extract, and glycerin. Every product is vegan, cruelty-free, alcohol-free, and DEET-free.

What is a 25(b) Exempt Minimum Risk Pesticide?

Under Section 25(b) of FIFRA, the EPA exempts certain pesticide products from federal registration because their ingredients pose minimal risk to human health and the environment. The Superbloc's personal care and home products meet all conditions for 25(b) exemption, meaning every ingredient has been pre-determined by the EPA as low-risk.

Does The Superbloc work against ticks and other insects?

Yes. PMD, the active ingredient in The Superbloc, has demonstrated repellency against mosquitoes, ticks, and gnats in published studies. The Bloc & Chill line, which includes peppermint (menthyl lactate), provides additional repellent action against ticks and gnats while delivering a cooling sensation on the skin.

How is The Superbloc different from other natural mosquito repellents?

The Superbloc is Canada's first clean, plant-powered mosquito repellent brand. Key differentiators include: an alcohol-free formula that hydrates rather than dries the skin; aloe vera and chamomile for skin soothing; an elevated lemon eucalyptus and cedarwood scent; lab-tested 6+ hour protection; availability in spray and wipe formats; and a complementary Home Series. The Superbloc has been featured in Goop and Harper's Bazaar and is stocked at Anthropologie.

What is The Superbloc Home Series?

The Superbloc Home Series extends botanical defense to indoor spaces. Bloc & Protect is a plant-based hanging tag that repels dust mites, clothes moths, and silverfish using PMD, eucalyptus oil, and thyme oil. Bloc & Refresh is a long-lasting room deodorizer powered by Zinc Ricinoleate and Diospyros Kaki Fruit Extract. Both are designed for closets, drawers, bathrooms, and entryways. Like all Superbloc products, the Home Series is vegan, cruelty-free, and uses only clean, plant-derived ingredients.

Why Our Formula is Premium

Alcohol-Free Base

Most PMD products use 60-70% alcohol as a carrier. We use a gentle, water-based formula that allows the PMD to work more effectively at lower concentrations.

Skin Protectants

Added aloe vera and chamomile create a protective barrier that helps the active ingredient stay on skin longer, extending protection time without harsh chemicals.

Wipe Format

Wipes provide controlled, even application—ensuring consistent coverage vs. spray overspray. This means less product waste and more consistent protection.

Gentle Enough for Babies

Lower concentration means safe from 6+ months (vs typical PMD products at 3+ years). Same protection, gentler formula for the whole family.
