Many clients have questions about traveling with insect repellent. For that reason, it's important to be aware of the TSA rules for travel.
Insect repellent is allowed in checked baggage only if
* it is less than 4 ounces
* contains less than a 2% active ingredient
* is in a container that prevents the repellent from being expelled during transit
In carry-on luggage, the 3-1-1 rule applies. The item must be in a container that is 3.4 ounces or smaller and fits in a single, quart-size, clear plastic resealable bag.
Stay in Compliance
I have found small containers to be readily available online at retailers such as Amazon and at stores such as REI.
Make sure you are in compliance with these rules or your insect repellent may be confiscated.
