常見問與答

Natural mosquito repellents use plant-based active ingredients instead of synthetic chemicals like DEET. The Superbloc uses PMD (para-menthane-3,8-diol), derived from lemon eucalyptus oil. PMD is the only plant-based active ingredient recommended by the CDC as effective against mosquitoes that carry West Nile virus, Zika, and dengue.

Our Bloc Off products contain: PMD (8%), Eucalyptus Citriodora Oil (1%), Cedarwood Virginian Essential Oil (0.5%), Copaiba Essential Oil (0.5%), plus water, hydrogenated castor oil, glycerin, aloe barbadensis leaf juice, and chamomile extract.

Bloc & Chill uses the same base formula plus menthyl lactate (2%) for its cooling effect. All products are vegan, cruelty-free, and contain no DEET, no alcohol, and no harsh chemicals.

PMD-based repellents like The Superbloc provide up to 6+ hours of protection — comparable to low-concentration DEET products in clinical studies. A 2006 peer-reviewed study in the Journal of the American Mosquito Control Association concluded that PMD provides DEET-like efficacy. PMD is the only plant-based active ingredient recommended by the CDC.

PMD (para-menthane-3,8-diol) is a plant-based compound derived from the lemon eucalyptus tree. It is the only plant-derived mosquito repellent active ingredient recommended by the CDC. Unlike DEET, PMD has a pleasant citrus scent, does not damage plastics or synthetic fabrics, and has a favorable safety profile with no documented neurological adverse effects at recommended use levels.

No — this is an important distinction. PMD is the refined, concentrated active compound from the lemon eucalyptus tree that provides proven mosquito repellent action. "Lemon eucalyptus essential oil" is the raw, unrefined distillation product and has not been validated as an effective repellent. The CDC specifically recommends PMD/OLE products — not lemon eucalyptus essential oil.

Yes. Our products are lab-tested for 6+ hours of mosquito protection against key species including Aedes aegypti (Zika and dengue vector) and Culex species (West Nile vector). PMD as an active ingredient has been validated in multiple peer-reviewed clinical studies published in journals including the Journal of Medical Entomology and Scientific Reports.

Under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act), Section 25(b) exempt products are minimum risk pesticides that use active ingredients the EPA considers safe enough to be exempt from federal registration requirements. The Superbloc's products qualify as 25(b) exempt because they use PMD and other plant-based ingredients recognized as posing minimal risk to human health and the environment.

Yes. The Superbloc is safe for children 6 months and older. It is DEET-free, alcohol-free, and formulated with skin-soothing aloe vera and chamomile. Apply to your own hands first, then rub onto the child's exposed skin. Avoid contact with eyes and mouth.

For babies under 6 months, use mosquito netting on strollers and carriers instead of any repellent.

Yes. The Superbloc products are DEET-free, alcohol-free, and formulated as 25(b) exempt minimum risk pesticides under FIFRA. They are safe for children 6 months and older, and the CDC considers PMD products safe for use during pregnancy. Our products have a Health (H), Flammability (F), and Reactivity (R) rating of 0 across the board per our Material Safety Data Sheets — the lowest possible hazard ratings.

The CDC considers EPA-registered PMD products safe for use during pregnancy and while breastfeeding. The Superbloc is DEET-free and alcohol-free, making it a gentle option. We recommend consulting your healthcare provider for personalized advice during pregnancy.

The Superbloc products are formulated for use on human skin. While our plant-based ingredients are generally gentle, we recommend consulting your veterinarian before using any repellent product around pets, as some animals may have sensitivities to essential oils.

Yes. The Superbloc is formulated for daily use. The alcohol-free formula with aloe vera and chamomile is gentle enough for regular application without drying out or irritating skin.

Our products do not contain naphthalene, camphor, or other ingredients commonly flagged as triggers for G6PD deficiency reactions. However, if you or your child has G6PD deficiency, we recommend consulting your healthcare provider before using any new topical product, including natural repellents.

Yes. Our formulations are readily biodegradable according to OECD testing methods and pose no hazard to air, water, aquatic life, or humans in disposal testing. They are not classified as hazardous by DOT and contain no volatile organic compounds. Unlike DEET, which persists in surface water and soil, our plant-based ingredients break down naturally.

Our personal care products (Bloc Off and Bloc & Chill) repel mosquitoes, ticks, gnats, and biting flies. Our Home Series tags target dust mites, clothes moths, and silverfish. The Superbloc repels mosquito species known to carry West Nile virus, Zika virus, dengue fever, and chikungunya.

Both lines provide the same core mosquito protection using PMD. Bloc Off features a lemon eucalyptus and cedarwood scent. Bloc & Chill adds peppermint (menthyl lactate) for an instant cooling sensation — ideal for hot weather. Both come as sprays (80ml, 2-pack) and individually wrapped wipes (10-pack, 2-pack).

Spray: Hold 6–8 inches from skin and spray evenly on all exposed areas. Wipes: Open individual towelette and wipe onto exposed skin.

For children, apply to your own hands first, then rub onto the child's skin. Avoid eyes and mouth. Reapply after 6 hours, after swimming, or if sweating heavily.

Our personal care sprays and wipes provide 6+ hours of protection per application. Reapply if sweating heavily, after swimming, or if you start getting bitten. Our Home Series tags (Bloc & Protect and Bloc & Refresh) provide long-lasting protection for indoor spaces — simply hang and replace as needed.

Not at all — that's one of our core differentiators. Bloc Off has a fresh lemon eucalyptus scent with grounding cedarwood and pine notes. Bloc & Chill adds refreshing peppermint. Customers describe it as something they'd actually enjoy wearing.

Bloc & Protect uses PMD, eucalyptus oil, and thyme oil to repel dust mites, clothes moths, and silverfish. Bloc & Refresh uses Zinc Ricinoleate and Diospyros Kaki Fruit Extract to neutralize odors naturally. Hang them in closets, drawers, bathrooms, shoe cabinets, or door entries for long-lasting freshness and protection.
