Does Lysol Kill Bed Bugs?

Does Lysol Kill Bed Bugs?

Lysol, a popular disinfectant, is often considered for use in pest control due to its ability to kill bacteria and viruses. However, its effectiveness in killing bed bugs is a topic of debate.

Understanding Bed Bugs:

Bed bugs are resilient pests that hide in cracks, crevices, and fabric seams. They are nocturnal and feed on human blood, causing itchy bites and discomfort. Effective eradication requires targeting not just the adult bugs but also their eggs.

Lysol’s Limitations:

Lysol contains ingredients like ethanol and other compounds that can kill germs on contact. While it can kill bed bugs on direct contact, it is not a reliable solution for several reasons:

  1. Contact Requirement: Lysol needs to be sprayed directly on bed bugs to kill them. Since bed bugs hide in hard-to-reach places, it is nearly impossible to contact all the bugs and their eggs with Lysol.
  2. Surface Area Coverage: Lysol is not designed to penetrate the crevices where bed bugs hide. Spraying surfaces alone won’t ensure that all bed bugs are exposed to the disinfectant.
  3. Egg Resilience: Bed bug eggs are particularly resilient and may not be killed by Lysol. This means that even if you manage to kill some adult bed bugs, new ones could hatch and continue the infestation.

Effective Alternatives:

For a comprehensive solution, consider these more effective methods:

  1. Heat Treatment: Washing and drying bedding, clothes, and other items at high temperatures can kill bed bugs and their eggs.
  2. Professional Extermination: Pest control professionals use specialized treatments, including heat, steam, and stronger insecticides, to eliminate bed bugs thoroughly.
  3. Diatomaceous Earth: This natural powder dehydrates and kills bed bugs when they come into contact with it. It is safe to use around pets and humans.
  4. Encasements: Using bed bug-proof mattress and box spring encasements can trap and starve bed bugs, preventing them from spreading.


While Lysol may kill some bed bugs on direct contact, it is not an effective standalone solution for bed bug infestations. Comprehensive treatments and professional help are more reliable for eradicating these persistent pests.
