Bug sprays, mosquito sprays, or bug repellents is important when traveling to tropical, subtropical, or any regions with mosquitoes, ticks, or sandflies but can you take bug spray on a plane?
Here is the short answer:
You can bring skin-applied bug spray on a plane carry-on, but in limited quantities of 3.4 oz / 100 ml or less. The maximum allowed in checked luggage is 2 kg (70 ounces) or 2 L (68 fluid ounces). Each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
But what about other air insect sprays? and what size bug spray you can take on a plane? Some bug repellents are considered aerosols or toxic items that could potentially be used to harm someone.
In this post, I will cover everything you need to know about taking TSA approved mosquito spray in both carry-on and checked luggage.
Let’s dive right in.
TL;DR
You can bring bug spray on a plane, but only skin-applied repellents are accepted.
kin-applied repellents in carry-on: Max 3.4 oz / 100 ml per container, placed in a quart-size liquids bag.
Checked luggage: Total limit 2 kg (70 oz) or 2 L (68 fl oz) per person; each bottle max is 0.5 kg (18 oz) or 500 ml (17 fl oz).
Aerosol insecticides or air-sprayed bug killers (not used for skin) are not permitted in carry-on or checked bags if they’re flammable.
Wipes, creams, roll-ons, and solid repellents are the easiest, hassle-free options.
Final call is always TSA/security officer discretion, especially on international flights.

The TSA stated on its website that only bug sprays and repellent that can be used on the body or skin are allowed through the security checkpoint in limited quantities.

Can I Take Bug Spray In Carry-on?
You can bring bug spray (like DEET bug spray) in your carry-on bag as long as it meets carry-on limits: no more than 3.4 oz / 100 ml per container.
And just like any other liquids and aerosols, your bug spray must be placed in a quart-sized bag before placing it inside your carry-on.
Aerosols are hard to transfer or refill into smaller travel-sized containers, but you are more likely to find bug spray already available in travel sizes.

If you don’t want to deal with aerosols or can’t find a travel-sized container, you can opt for a cream-based repellent, which can be easily transferred into travel-size containers. You can also take bug repellent wipes.
There are no restrictions applied to wipes, and most travelers prefer them as they can also be used as hand sanitizer alternatives.
Can I Bring Bug Spray In Checked Luggage?
Just in carry-on bags, bug sprays for personal use that can be applied to the human body, such as repel or homemade spray are allowed.
But, since they are considered toiletries, they ave also some limit but not exactly carry-on bags, here is the limits as mentioned by the FAA on its website.
The total quantity per person must not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). FAA website
Bug sprays or insecticides that are not intended for skin use and are flammable are not permitted in checked luggage, as they are considered dangerous items. These products are not considered necessary or medical items.

The AskTSA team replied with the same guidance mentioned above.
Bug repellents that can be used on the skin are allowed in limited quantities, while other types of insecticides will not be accepted because they are considered dangerous items. However, they did not mention whether the container indicates that the item is flammable.
Note: It is better to avoid placing any expensive items in checked luggage, whether it’s an expensive or necessary repellent that you can’t easily replace, or any other valuable items.
How To Pack Bug Spray For Travel Perfectly?
If you are traveling with a small bottle of skin applied bug repellent (less than 3.4 oz / 100 ml), you can easily place it in your carry-on bag with other liquids inside a quart-sized bag.
It is recommended to add extra protection to the container cap to prevent it from accidentally spraying inside your bag.
If you place your bug spray in checked luggage, it’s best to wrap the bottle with tape or plastic and then place it inside a sealed plastic bag.
Checked luggage is often handled roughly and tossed around, so to avoid spills inside your bag, double-check that all bottles are fully secured and placed in the middle of your luggage.
Final Thoughts
You can bring bug spray, bug repellent, or mosquito repellent that is intended for use on human skin on planes, but only in limited quantities, just like other liquids and aerosols.
In carry-on bags, each container must be 3.4 oz / 100 ml or less and placed inside a quart-sized bag.
In checked luggage, you can bring full-sized bug repellent, but since it is considered an aerosol, each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
I hope this helps.
Happy travels
