Can Cockroach Spray Kill Lizards?

Table of Contents

This is a question we hear a lot, so we did some research to find out. It turns out that the answer is yes, cockroach spray can kill lizards.

Cockroach spray works by suffocating the lizards. The chemicals in the spray will block the lizards’ respiratory systems, causing them to die.

So, cockroach spray is a good option if you’re looking for a way to kill lizards.

However, using the spray correctly is essential to avoid harming yourself or your home.

The Truth About Cockroach Spray

Cockroach spray is made of chemicals that are designed to kill cockroaches.

These same chemicals can also harm humans and pets if they’re not used properly. In most cases, the concentration of these chemicals is too low to kill a lizard outright.

However, it could be fatal if you use too much spray or if the lizard comes in contact with it directly.

So, using cockroach spray correctly is essential to avoid harming yourself, your pets, or your home.


You can use cockroach spray to kill lizards in your house, but you need to be very careful about how you use it.

We recommend using a low-concentration spray and avoiding spraying it directly on the lizard. A low concentration such as 0.5% should be refined.

You should also ensure that you’re using the spray in a well-ventilated area and wearing gloves and a mask to avoid inhaling the chemicals.

Finally, you should read the label carefully and follow the instructions to avoid harming yourself or your home.

Otherwise, you could end up harming yourself, your home, or your pet.

How to Use Cockroach Spray Safely?

If you’re going to use cockroach spray to kill a lizard, there are a few things you need to keep in mind.

Use the right kind of spray.

First, make sure that you’re using the right kind of spray.

There are two types of cockroach sprays: aeros meeting and contract killing.

Aeros meeting is the most common type of cockroach spray.

It’s designed to kill cockroaches on contact, but it’s not as effective at killing lizards.

On the other hand, contract killing sprays are designed to kill cockroaches and their eggs. This type of spray is more likely to be effective at killing lizards, but it’s also more toxic.

If possible, you should use a contact-killing spray to kill the lizard more effectively.

Spray correctly

Next, you must ensure that you’re using the spray correctly. You should always read the manufacturer’s instructions before using any kind of pesticide.

You’ll want to apply the spray directly to the lizard whenever possible.

If you can’t reach the lizard, you’ll need to be careful not to get the spray on any surfaces that humans or animals come into contact with regularly.

Ventilate the area

Finally, make sure that you ventilate the area after using cockroach spray.

This will help to prevent any harmful chemicals from building up in your home.

Duration for cockroach spray to kill lizards

The time it takes for cockroach spray to kill a lizard will depend on several factors, including the type of spray you’re using and the size of the lizard.

In most cases, it will take a few minutes for the lizard to die.

However, if you’re using a low-concentration spray, it could take up to an hour for the lizard to die.

Can Cockroach Spray Kill Garden Lizards?

The answer to this question is a bit more complicated. Garden lizards are usually much smaller than the lizards that live inside your home.

This means they’re more susceptible to the harmful chemicals in cockroach spray.

In addition, garden lizards are often found near areas where cockroaches congregate.

This means that they’re more likely to be exposed to the spray.

So, while it’s possible that cockroach spray could kill a garden lizard, it’s not likely.

If you’re concerned about lizards in your garden, other control methods are more effective and less harmful.

Can Lizards Bite While You Are Spraying Them? Do They Even Have Teeth?

Lizards can bite while spraying them, and they have teeth!

Some lizards have very sharp teeth that can easily break the skin.

So, if you are going to spray a lizard with cockroach spray, be sure to wear gloves and long sleeves to protect yourself from getting bitten.

Can Lizards Die If They Eat Sprayed Cockroaches?

While we cannot say for sure that lizards will die if they eat sprayed cockroaches, it is not a good idea.

The chemicals in the spray can be harmful if ingested and could make lizards very sick. Also, cockroaches may be sprayed in areas with food or water.

Lizards could contaminate their food or water source if they eat these cockroaches.

To sum it up, cockroach spray can kill lizards, but it may not be the best control method.

If you must use cockroach spray, follow the manufacturer’s instructions carefully and take steps to protect yourself and your pets from exposure.

If you have further questions about using cockroach killers safely, don’t hesitate to contact a pest control professional for advice.
