Can You Bring Bug Spray on a Plane?
Yes, if it is for your skin. Personal insect repellent follows the toiletry rules: 3.4oz in carry-on, larger in checked. Area foggers and permethrin sprays are not allowed.

The official word
Straight from the FAA
“This exception is for repellents that are sprayed or applied directly on a person’s skin and clothing. Insect repellents or insecticides designed to be sprayed in the air or at the insect are not included.”

Before the checkpoint
Three calls that matter
The rule turns on use. Repellent for your body is a toiletry; a fogger meant to spray a room is not allowed.
Repellent wipes and lotions skip the aerosol and liquid limits, ideal for a carry-on.
In checked bags, aerosol repellent counts toward the same 68oz total limit as other aerosol toiletries.
