Will Lysol Kill Cockroaches?

Yes, Lysol will kill cockroaches, but only if you spray it directly on the cockroach or cockroaches when you see it. Spraying around where you have seen cockroaches may not be effective because the spray needs to get into the cockroach’s spiracles to kill it.

You need to know, however, that cockroaches can survive up to 6 hours without oxygen. So do not just spray it on the roach and forget it. The spray may just have incapacitated the roach for some time. Spray enough to actually kill the cockroach.


How Does Lysol Kill Roaches

Lysol kills roaches when it is sprayed directly on the cockroach. Why does it need to be sprayed on the roach? This is because cockroaches are invertebrates; like other invertebrates, they breathe with their spiracles.

These spiracles are holes they have on their sides. When you spray on a cockroach, the body absorbs the ingredients in the spray, and when these ingredients get into the body, they destabilize the cockroach’s nervous system or block off the spiracles they use to breathe, which will make them die.
