Why Lysol Isn’t a Long-Term Solution
- Requires direct contact to be effective
- Not fast-acting, especially on larger roaches
- Doesn’t target nests or eggs
- Leaves no residual effect, so it won’t prevent more roaches from appearing
What Happens When You Spray Lysol on a Roach?
Lysol’s alcohol and cleaning agents can irritate a roach’s respiratory system and potentially lead to death if enough is sprayed. Most roaches will likely survive a light mist and simply run away.
Better Alternatives to Kill Roaches
For more effective control, consider…
- Gel baits – Attracts and poisons roaches at the source
- Insecticidal sprays – Formulated specifically to kill insects
- Boric acid or diatomaceous earth – Long-lasting and lethal to roaches
- Professional pest control – For severe or recurring infestations
Lysol can technically kill a cockroach if you spray a lot of it directly on the bug, but it’s not a recommended method for dealing with an infestation. For lasting results, use proper roach control products or ask a pest professional.
