DIY Mosquito Repellent Spray with Essential Oils and Without Rubbing Alcohol

Safety Tips for Adults, Kids, and Pets

Patch testing and dilution basics

Always patch test on a small area for 24 hours before wider use. Even skin-safe essential oils can irritate sensitive skin, especially in summer heat.

For adults, I stay around 1% to 2% dilution for leave-on body sprays. More is not automatically smarter.

Kids and essential oils

For babies and toddlers, I would skip DIY essential oil sprays and use protective clothing, stroller nets, and pediatrician-approved options. For older kids, I still prefer extra caution and lower dilutions.

Also, oil of lemon eucalyptus products are not recommended for children under 3, and plain lemon eucalyptus essential oil is not a substitute for those tested products anyway.

Pet safety matters

Be very careful with essential oils around pets, especially cats. Oils like tea tree, peppermint, eucalyptus, and even some common diffuser blends can be a problem.

Do not spray pets with this recipe. I know people do it online, but I’m firmly in the “absolutely not” camp there.

When to use a tested commercial repellent instead

If you’re in a high-risk area for mosquito-borne illness, camping in thick woods, or dealing with intense mosquito pressure, use an EPA-registered repellent. DIY is fine for light, everyday situations, but it has limits.

I love homemade projects, but I’m not weirdly loyal to them. Next, hit the next button below, because shelf life is where a lot of DIY sprays quietly go wrong.
