1. Ethanol/SD Alcohol 40:

This is a typе of alcohol that you find in Lysol. It’s rеally good at killing gеrms and bactеria. Whеn it comеs to pеsts likе cockroachеs, еthanol acts as a strong rеpеllеnt.

This is what wе brеathе out, and it’s also in Lysol. In thе world of pеsts, carbon dioxidе can bе usеd to lurе insеcts into traps, but in Lysol, its concеntration is too low to havе a significant impact on cockroachеs. It’s mainly thеrе to hеlp thе spray comе out of thе can еvеnly. So, whilе it doеsn’t do much to thе pеsts, it hеlps in making thе product еasiеr to usе.

Lysol is grеat for kееping your homе clеan and rеducing thе chancеs of pеsts, but for a big roach problеm, you might nееd somеthing strongеr.

The Effectiveness of Lysol Against Cockroaches

Ingredients in Lysol and Their Effects on Pests (1)

Lysol is a cleaning product, and it’s really good at killing germs. But cockroaches? They’re a whole different story. These little critters are known for their survival skills. They’ve been around for millions of years, adapting to all kinds of environments. So, when you spray Lysol on them, it might annoy them or even kill some, but it’s not the best solution to get rid of a roach infestation.

Lysol contains ingredients that can affect cockroaches. If you spray it directly on them, it might kill them because of the harsh chemicals. But cockroaches are sneaky and fast. They often hide in places where it’s hard to reach them with a spray. Plus, Lysol evaporates quickly, which means it won’t last long enough to keep killing roaches that come later.

While Lysol might not be the best cockroach killer, it does have a role to play. Keeping your home clean is key to preventing cockroach infestations. Regularly cleaning with Lysol can help keep your space germ-free and less attractive to roaches. They love dirty, crumb-filled environments, so a clean home is less inviting to them.

What Kind of Lysol Kills Roaches

If you’re looking for ways to combat cockroaches and wondering if any type of Lysol can help, you’re in the right place. Let’s explore the different kinds of Lysol and see how they might work against roaches.

Lysol Disinfectant Spray:


This is probably the most common Lysol product you’ll find in homes. It’s great for killing germs on surfaces and has a strong scent. When it comes to roaches, spraying this directly on them might kill them due to the harsh chemicals.

However, it’s more about luck and timing. The roach has to be directly sprayed, and even then, it’s not guaranteed to work every time. Plus, the effect doesn’t last long, so it won’t prevent other roaches from coming back.

Lysol Multi-Surface Cleaner:

Lysol Multi-Surface Cleane

This type is used to clean floors, counters, and other surfaces. While it makes your home clean and less inviting to roaches, it doesn’t specifically kill them. If a roach walks over a freshly cleaned surface, it might not like the chemicals and run away, but it probably won’t die from it.

Lysol Toilet Bowl Cleaner:

Lysol Toilet Bowl Cleaner

This one is strong and is used to clean toilets. It’s not really meant for dealing with roaches. If by chance a roach comes into direct contact with it, the harsh chemicals might harm it, but again, it’s not a reliable way to kill roaches.

Type of LysolEffect on Roaches
Lysol Disinfectant SprayMight kill on direct contact

How Does Lysol Kill Roaches

Lysol is mainly known for its ability to clеan and disinfеct surfacеs. It’s packеd with chеmicals that arе tough on gеrms and bactеria. Now, whеn it comеs to roachеs, thеsе chеmicals can bе prеtty harsh on thеm too. If you spray Lysol dirеctly on a cockroach, it might kill it. This happеns bеcausе thе chеmicals in Lysol can affеct thе roach’s outеr shеll, and if thе spray is strong еnough, it can pеnеtratе and harm thе roach.

Howеvеr, it’s not as simplе as it sounds. Roachеs arе known for thеir strong survival skills. Thеy’rе fast and good at hiding in small spacеs whеrе sprays can’t rеach. Plus, Lysol еvaporatеs quickly, which mеans it doеsn’t stay on surfacеs for long. So, еvеn if you spray it around your housе, it’s not going to kееp killing roachеs ovеr timе.

Also, rеmеmbеr that Lysol is a clеaning product, not a dеdicatеd pеst control solution. Whilе it might work in a pinch if you sее a roach and havе nothing еlsе on hand, it’s not thе bеst way to dеal with a roach infеstation. For sеrious roach problеms, you might nееd to usе products spеcifically dеsignеd to kill and prеvеnt roachеs. 

How to Use Lysol to Combat Cockroaches


Battling cockroaches in your home can be a real headache, right? If you’re thinking of using Lysol as part of your plan to fight these pests, here’s a step-by-step guide. Remember, while Lysol isn’t a surefire way to eliminate roaches, it can help in keeping your space clean and less welcoming to them.

Step-by-Step Guide:

  1. Identify Roach Hotspots: First, find out where the roaches are hanging out. Usually, they love kitchens and bathrooms because they can find food and water there.
  2. Clean Thoroughly: Use Lysol to clean these areas well. Wipe down countertops, mop floors, and clean behind appliances. Roaches are less likely to stay in clean places.
  3. Spray Lysol Directly on Roaches: If you see a roach, you can spray Lysol directly on it. This might kill it if the spray is strong enough.
  4. Regular Cleaning: Keep using Lysol regularly to clean your home. This won’t just help with roaches but will also keep your house germ-free.

Safety Precautions:

While using Lysol, it’s important to be safe. Here are some tips:

  • Ventilation is Key: Always make sure the room is well-ventilated when you’re spraying Lysol. Open windows and doors to let fresh air in.
  • Avoid Contact with Food: Be careful not to spray Lysol near your food or kitchen utensils.
  • Use Gloves: It’s a good idea to wear gloves when cleaning with Lysol, especially if you have sensitive skin.
  • Don’t Mix Cleaners: Never mix Lysol with other cleaning products. Some combinations can be dangerous.
  • Keep Away from Pets and Younger Siblings: Make sure pets and little brothers or sisters aren’t around when you’re using Lysol.

How to Make Lysol Spray

YouTube video

Are you running out of Lysol spray at home and wondering if you can make your own? Good news! You can create a DIY version using simple ingredients. This homemade spray can help keep your space clean and fresh. Here’s how to make your own Lysol-like spray. Remember, while this homemade version is good for cleaning, it might not be as effective as the real Lysol in killing germs.

Ingredients You’ll Need:

  • Rubbing Alcohol or Ethanol (70% concentration): This is the main germ-killing ingredient.
  • Water: To dilute the alcohol.
  • Essential Oils (like lemon, lavender, or tea tree oil): These add a nice scent and can have additional cleaning properties.
  • A Spray Bottle: To store and use your homemade spray.

Steps to Make Your DIY Lysol:

  1. Mix Alcohol and Water: In your spray bottle, mix 2 parts of rubbing alcohol with 1 part of water. For example, you can use 1 cup of alcohol and ½ cup of water.
  2. Add Essential Oils: Add about 10-15 drops of your chosen essential oil. This will give your spray a pleasant smell and can add extra cleaning power.
  3. Shake Well: Put the lid on your spray bottle and shake it well to mix everything together.
  4. Label Your Bottle: Don’t forget to label your bottle so everyone knows what’s inside.
  5. Test it Out: Before using it all over, test your spray on a small area to make sure it doesn’t damage any surfaces.

Safety Tips:

  • Be Careful with Alcohol: Remember, alcohol is flammable. Don’t use your spray near open flames.
  • Ventilate the Area: When spraying, make sure the room is well-ventilated.
  • Wear Gloves if Needed: If you have sensitive skin, wearing gloves can be a good idea.

This homemade spray is great for a quick clean-up and leaves a fresh scent. It’s a fun and useful DIY project. However, for serious germ-killing, especially during flu season, it’s better to use commercial products that are proven to be effective.

How Fast Does Lysol Kill Roaches

First, it’s important to know that Lysol isn’t a specialized roach killer. It’s made to clean and disinfect surfaces, not to fight bugs. But, if you spray Lysol directly on a cockroach, it could kill it. This happens because the chemicals in Lysol are pretty harsh and can be harmful to roaches.

Now, about the speed – if Lysol does kill a roach, it can be pretty quick. If you manage to spray it directly on the roach, it might die within a few minutes. But catching a roach and spraying it directly is not always easy. They’re fast and good at hiding, so you might not always have a chance to spray them.

Remember, while Lysol can kill roaches on direct contact, it’s not the best way to handle a roach problem. It won’t keep killing roaches that come later, and it’s not great for reaching the hidden spots where roaches hide.

Does Lysol Kill Roach Eggs

The answer is not really yes. Lysol’s chemicals might not be able to penetrate the ootheca to kill the eggs inside. This means even if you spray Lysol around, the roach eggs can still hatch and you might have new roaches running around soon.

While Lysol can sometimes kill roaches if sprayed directly on them, it’s not effective against roach eggs. To really get rid of a roach problem, you’ll need more than just a cleaning spray. Keeping your home clean and using proper pest control methods are the best ways to fight roaches.

Lysol vs. Well-Known Insecticides

When it comes to dealing with bugs in the house, it’s important to choose the right tool for the job. Let’s compare Lysol, a popular household cleaner, with some well-known insecticides to see how they stack up.



  • Purpose: Lysol is primarily a cleaner and disinfectant. It’s great for making surfaces germ-free and giving your home a fresh smell.
  • Effectiveness Against Bugs: If you spray Lysol directly on bugs like cockroaches, it might kill them. This is because the chemicals in Lysol are quite strong. However, this isn’t guaranteed and Lysol isn’t specifically designed for pest control.
  • Safety: Lysol is generally safe for home use if you follow the instructions. Ensure good ventilation when using it.
  • Lasting Effect: Lysol does not have a lasting effect on bugs. It cleans surfaces but doesn’t prevent bugs from coming back.

Well-Known Insecticides (like Raid, Ortho Home Defense):

Raid Fly Insect Killer

  • Purpose: These products are specifically designed to kill insects. They come in various forms – sprays, baits, and powders.
  • Effectiveness Against Bugs: They are formulated to effectively kill bugs and sometimes their eggs. They are typically more reliable for pest control than Lysol.
  • Safety: Some of these insecticides can be strong and may require leaving the area for some time after use. Always read and follow the safety instructions.
  • Lasting Effect: Many of these products provide a long-lasting barrier that continues to kill bugs over time.

Pros and Cons of Using Lysol

Using Lysol around the house has its ups and downs. Let’s take a look at what’s good about using Lysol and what’s not so great.

Advantages of Using Lysol:

  • Kills Germs: Lysol is great at killing germs on surfaces. This helps keep your home clean and can reduce the risk of getting sick.
  • Easy to Use: Just spray and wipe! Lysol is super user-friendly, making cleaning a breeze.
  • Fresh Scent: It leaves behind a fresh, clean smell, making your home feel nice and inviting.
  • Versatile: You can use it on many different surfaces like counters, bathroom fixtures, and door handles.

Potential Drawbacks of Using Lysol:

  • Not a Pest Control Solution: While it can kill bugs on direct contact, it’s not really designed for pest control. So, don’t rely on it to solve a bug problem.
  • Chemicals: Lysol contains chemicals. If you’re not careful, it can irritate your skin, eyes, or lungs, especially in a non-ventilated area.
  • Not Environmentally Friendly: The chemicals in Lysol aren’t great for the environment. Plus, the aerosol sprays contribute to air pollution.
  • Can Damage Certain Surfaces: Be careful where you spray it. Lysol can damage certain materials like painted surfaces or fabrics.

Wrap Up

To wrap it up, Lysol is a powerful cleaning tool that’s great for keeping your home germ-free and smelling fresh. However, when it comes to dealing with cockroaches or other pests, it’s not the most reliable solution. While Lysol can kill bugs on direct contact, it’s not designed for long-term pest control. It’s important to use Lysol safely, considering its chemical content and potential effects on the environment. For serious bug problems, you’re better off using products made specifically for pest control. Remember, a clean home is a happy home, but for those pesky bugs, sometimes you need a little extra help!


Using Lysol around pets requires caution. Some pets can be sensitive to the chemicals in Lysol, especially birds and small animals. It’s best to use Lysol in well-ventilated areas and keep pets away until the area dries completely. Always check the label for safety instructions and consider your pet’s health and sensitivities.

Lysol can kill German roaches if you spray it directly on them, due to its strong chemicals. However, it’s not the most effective or reliable method for a roach infestation. German roaches are particularly tough, and Lysol isn’t designed for long-term pest control. For a serious roach problem, specialized pest control products are a better choice.

If you spray Lysol directly on a roach, it might kill it, but not always instantly. The effectiveness depends on the direct contact and amount of Lysol used. However, Lysol isn’t a guaranteed or quick solution for a roach problem. It’s more of a temporary fix and doesn’t always work on the spot.

Lysol spray can kill bugs if it’s sprayed directly on them, as the chemicals in Lysol are harsh. But, it’s important to know that Lysol isn’t designed as a bug killer. It’s more effective as a disinfectant for cleaning surfaces. For dealing with bugs, especially serious infestations, using products specifically meant for pest control is recommended.
