can lizards be killed by cockroach spray

Contrary to many popular opinions lizards are not dangerous neither they are poisonous.

In fact, there are many health benefits offered by lizards in our surroundings – as they help in reducing the flying insects by preying on mosquitoes, flies, and moths.

Like human beings and others, these creepy creatures are part of our Ecosystem.

And killing them can cause a few unwanted problems for you.

If, however, you want to kill the lizards in your home – using a cockroach red HIT spray can work for you.

Even though a mosquito spray like Raid Max, Baygon, or HIT may not work to kill the lizards instantly, these bug sprays if used in sufficient quantity do hurt them a lot and can slowly cause death.

These sprays and insecticides are so powerful that they can harm human beings, so they can surely kill the lizards.

But you may sometimes need to spray a dozen times to kill these pesky lizards before they get on their deathbed.

Generally speaking, after a spray or two these irritating pests feel uneasy and they will try to escape at a place wherever possible.

The half-dead lizard may try to hide but will come out soon in the open as it can’t breathe properly.

You will then get a chance to spray more. Keep on spraying the liquid for a few seconds and you will soon find it dead.

In the process of using these mosquito killer sprays for killing the lizards remember to cover your skin and nose properly.

Do not breathe in the strong roach spray or any other pesticide spray as it can severely irritate or can block your throat.

Use anti-bacterial solutions if possible to clean the walls, floors, windows, and ceilings.

A small opening is a simple way for lizards to enter your home.

You may also consider placing the furniture in your home 5 inches away from the walls, where the lizards often hide.

Metal screens can also be utilized for covering your open windows and doors.

Are Lizard Droppings Poisonous – What to Do If You Find Them in Home?

Now when you know how to shield your home with lizards, it’s also important to know about their poop.

As an identification, lizards’ droppings are usually black in color with white tips.

Like all reptiles, lizards expel their fecal matter (urine and stool) through the same opening.

The white tip found on the feces is of uric acid crystals which is due to the highly concentrated urine.  

The smaller-sized common geckos at home usually have a dropping about a quarter-inch long and one-eighth inch wide.

Since the lizards may carry Salmonella that can cause serious health problems in people, their droppings can be dangerous too.

Although not poisonous in nature, the droppings of house lizards can contaminate your food and beverages that can cause food poisoning if consumed.

Droppings if small in number (like two to four) may go unnoticed in your kitchen and household.

But if you find it present in huge numbers it can cause a significant problem for you and your family.

It’s important to:

  • Avoid inhaling any dust from the dried feces
  • Wash your garden vegetables thoroughly before consuming
  • Keep your dishes and food covered in your kitchen if you find them
  • Remove the droppings using a vacuum cleaner as soon as you find them in your home
  • If it’s wet, you can use a dampened cloth (in soap water) to clean the surface. You can also use rubbing alcohol to clean

Also, take proper steps to eradicate the lizards permanently from your home which will help you stay safe from their harmful droppings.
