Insecticide / Bug Spray (Household)
Household insecticide sprayed at insects or into the air is banned from both carry-on and checked baggage.
Carry-on
Not allowed
Checked
Not allowed
Carry-on details
Not allowed. Insecticides designed to be sprayed into the air or directly at insects — ant spray, roach spray, and similar products — are banned from carry-on entirely. This is different from insect repellent applied to skin, which follows the standard liquids rule instead.
Checked-bag details
Not allowed. The same ban applies to checked baggage.
Special instructions
Skin-applied insect repellent (like the kind you spray on yourself before hiking) is a different product and is allowed under the standard 3.4 oz liquids rule in carry-on — see the insect repellent entry.
FAQ
- Is all bug spray banned from flying?
- No — it depends on how it's used. Repellent sprayed on your skin follows the standard liquids rule and is allowed. Insecticide sprayed into the air or at insects is banned entirely, in both carry-on and checked baggage.
