Does Lysol kill roaches on contact?

Yes, Lysol kills roaches on contact. If you do not directly spray the disinfectant on the pest, it will not kill them. However, Lysol doesn’t kill roaches instantly. It will take some time before killing roaches.

When you apply a good amount of Lysol to a roach, the pest will start suffocating. The toxic ingredients in the Lysol will make roaches breathless and finally will kill them.

What ingredients in Lysol kill roaches?

Ethanol and isopropyl alcohol are Lysol’s key ingredients that help kill roaches. When the roaches come in contact with these chemicals, they start to suffocate and eventually die.

Besides, Didecyl dimethyl ammonium chloride is another chemical that is harmful to roaches. It is a disinfectant and is capable of eliminating various germs. The chemical is also toxic to roaches.

How long does it take for Lysol to kill roaches?

Lysol may take 2 to 3 minutes or more to kill a roach completely. You should directly spray the Lysol on the roach, and within a few minutes, it will be dead.

However, roaches are quite a tough pest. They may not always die easily. After spraying Lysol on them, you may find the roach lying down motionless on the floor. But that doesn’t mean it is dead. In every few seconds or minutes, it may try to move. You do not have to worry as the pest will not be able to move due to the Lysol’s toxic effect. You can throw the cockroach away from home, and it will die soon. 

Does Lysol keep roaches away?

Yes, Lysol helps to keep roaches away but only to a limited extent. When you spray your home with Lysol, its strong smell will repel roaches. But as soon as the smell mitigates, the pests will return.

In other words, Lysol can be your temporary solution to keep roaches away. But for permanent results, you may need to switch to other methods.

Why do pest control companies ask you not to use Lysol?

Pest control companies use pesticides in your home that are toxic. If you use Lysol, it will wash off the pesticides from your home, making them ineffective. That is why pesticide companies may ask you not to use Lysol after they clean your house with pesticides.

Can all disinfectants kill roaches?

No, not all disinfectants can kill roaches. The disinfectant must include a high level of alcohol or ethanol in it to kill roaches.

The main purpose of disinfectants is to kill germs and not roaches. Hence, it will be better if you buy a roach killer to eliminate roach infestation.
