Can Lizards Be Killed By Cockroach Spray

If you spot lizards crawling on your wall however the only chemical spray you have is for cockroaches, you are probably wondering can lizards be killed by cockroach spray? After all, you probably have a couple cans of cockroach spray underneath your kitchen sink.

Cockroach spray will kill lizards either by consuming the poison or if absorbed directly through their skin. Lizards have a high metabolism and a low metabolic rate, so they are unable to detoxify the insecticide poison quick enough to stay alive.

With so many cockroach sprays available, you might be confused if the one you have will kill lizards. Besides, you might not know how much or how often you need to apply the spray to eliminate the lizards for good. 

Luckily, the detailed information below provides you with more than enough effective choices. So, let’s tell you everything you need to know about lizard killing sprays and how you can kill lizards using cockroach sprays.

Lizard Killing Spray

According to a review on pesticide effects on lizards by the Department of Conservation in New Zealand, many types of pesticides have been used over the decades to get rid of lizards. 

Insectivorous and predatory lizards are usually at risk of secondary poisoning when they consume poisoned prey. Some lizards were reported dead after their habitat was sprayed with termite control pesticide, which is proof that lizards are susceptible to insecticides. 

The main reason lizards die from insecticides, such as cockroach spray, is their low metabolic rate. High metabolism ensures that the body quickly alters the poison’s chemical nature to render it less toxic; hence, with a low metabolic rate, the opposite is true. 

Their inability to detoxify fast results in a quick death. Below are a few products to prove that lizards can be killed by cockroach spray.
