Can You Bring Insect Repellent on a Plane?

Yes — but the rules depend on the form. Solid sticks and wristbands have no restrictions. Aerosol sprays and pump sprays are subject to the 100 ml carry-on rule. Lotions and creams also fall under the 100 ml limit. In checked baggage, nearly all formats are allowed in larger sizes, with limits applying mainly to flammable aerosols.

Aerosol Insect Repellent Sprays

Aerosol insect repellent sprays — DEET spray cans, OFF! Outdoor Spritz, Sawyer Premium DEET aerosol, Repel 100 — face two overlapping rules in carry-on:

The liquid/aerosol rule: Each container must be under 100 ml and must fit in your 1-litre clear resealable liquids bag.

The flammable aerosol rule: Most insect repellent aerosols use flammable propellant. In carry-on, this does not add further restrictions beyond the 100 ml limit. In checked baggage, flammable aerosol toiletries and personal care products (which includes insect repellents) are allowed up to 500 ml per can and a combined total of 2 kg or 2 litres across all such aerosols per passenger.

Standard 100 ml travel-size DEET aerosol cans are available from most outdoor brands and pass the carry-on rule without any issue.

Pump Spray Insect Repellent (Non-Aerosol)

Pump-spray repellents — bottles with a push-down pump rather than a pressurised aerosol valve — are subject to the liquid rule only. No flammable aerosol concern applies.

• Maximum 100 ml per container in carry-on
• Must fit in your clear liquids bag
• Larger bottles can go in checked bags with no aerosol restriction

Pump sprays in travel sizes of 50 ml to 100 ml are common and pass through carry-on security without difficulty.

Lotion and Cream Insect Repellent

Lotion, cream, and gel insect repellents follow the standard liquid rule:

• Maximum 100 ml per container in carry-on
• Must go in your clear liquids bag
• In checked bags, any size is allowed (no aerosol concern for lotions)

This applies to picaridin lotions (Sawyer Picaridin, Natrapel), DEET creams, and natural plant-based repellent balms.

Solid Stick Insect Repellent

Solid stick insect repellents — similar in format to a solid deodorant stick — are classified as solids by security. They are not subject to the liquid rule.

• Any size is allowed in carry-on
• No need to place them in your liquids bag
• No quantity limit in carry-on or checked bags

This makes solid stick repellent one of the most convenient formats for carry-on travel. Products like Natrapel wipes in individual packets and solid stick formulas fall into this category.

DEET Concentration: No Restriction

Airport security rules do not distinguish between DEET concentrations. A 100% DEET product travels under exactly the same rules as a 30% DEET or 10% DEET product. The rules depend entirely on the physical form (aerosol, lotion, solid), not the active ingredient percentage or strength.

Picaridin-based repellents and natural repellents containing lemon eucalyptus or plant-based active ingredients follow exactly the same form-based rules as DEET products.

Mosquito Repellent Wristbands

Mosquito-repellent wristbands (Mosquito Guard, Pic wristbands, PARA'KITO bands) are not subject to liquid rules. They are allowed in any quantity in carry-on and checked bags with no restrictions.

Citronella Candles

Citronella candles with solid wax are allowed in carry-on and checked bags. The wax is a solid and has no liquid classification. Citronella oil in liquid form (in a small bottle) would be subject to the 100 ml liquid rule in carry-on.

Mosquito Nets

Mosquito nets are unrestricted. They can be packed in carry-on or checked baggage in any quantity, with no security classification concerns.

Tips for Traveling with Insect Repellent

For tropical destinations where repellent matters most: Consider buying a full-size bottle of your preferred repellent at your destination. Pharmacies and supermarkets in Southeast Asia, Central America, and East Africa carry well-known brands at reasonable prices, and you avoid the carry-on size restriction entirely.

For carry-on-only trips: A 100 ml pump spray or lotion fits the liquid rule, or a solid stick eliminates the problem entirely. Most outdoor retailers sell travel-size formats specifically sized for the carry-on rule.

Checked bag travelers: Pack a full-size aerosol (up to 500 ml) alongside other aerosol toiletries, keeping the 2 litre total limit in mind if you have multiple aerosol products.

Picaridin and natural alternatives: Both follow the same rules as DEET by form. If you prefer a DEET-free product, the same table above applies — choose the form that works best for your baggage situation.
