Where Are Cockroaches Found?


Cockroaches are found on every continent in the world other than Antarctica. They prefer warm and humid climates but can also survive in drier climates.

Cockroaches tend to like dark, wet locations to hide and reproduce, and they can be discovered hiding under refrigerators, sinks, and stoves. They can also be found hiding under floor drains and inside motors and other essential equipment.

These pesky critters come in four different shapes! Some are:

  1. Flat and brown.
  2. Long and brown.
  3. Round and dark, with light stripes on their bodies.
  4. It looks like a small version of the long brown roach, but with more light stripes on its body.

They do not have wings, so they can’t fly. Even if you brush them off the wall with a broom, they will only ride the broom down the hall to a new hiding spot. Cockroaches can live on or under almost any surface or ground material, including wood beams and adhesive tiles. They can crawl up through cracks in floors. Most cockroaches live on three legs and have six long antennae, which they use to feel their way around, find food, and communicate with each other when feeling threatened.

Cockroach Basics:

  1. Cockroaches are not poisonous but are considered pests because they “feed” off humans and other animals living in the building.
  2. Cockroaches carry bacteria like Salmonella and can cause food poisoning. They also carry viruses but are weaker because they are not passed from the roach to us when eating without first being in our bodies for a few hours.
  3. Children, pregnant women, and adults with weakened immune systems are at risk from salmonella, E. coli, hepatitis A, and staphylococcus infections, so if a roach that has carried one of these things becomes sick or dies on your food or water supply.

How Do You Get Rid of Cockroaches?

Getting rid of cockroaches is not an easy thing. If they are not a major problem where you live, it might be best to call an exterminator. However, if you live in a place that has roaches and you know how to kill them, follow the steps below:

  • Use commercial pesticides that contain boric acid or diatomaceous earth as bait for roach traps and use them according to instructions.
  • Clean up grease from your kitchen, as this attracts roaches.
  • Eliminate food sources such as crumbs or leftover food on counters, tables, and floors-all places that roaches like to hide out.
  • Do not leave dirty dishes of food or dishes with water on the counter; keep them in the dishwasher!
  • Vacuum and sweep frequently, especially under furniture and behind appliances.
  • Empty the crisper drawers in your refrigerator every week.
  • Keep your pet away from areas where roaches hide. If you find a roach in your house, you can kill it with an insecticide like Raid® or boric acid. Stick with these two types of insecticides if you find live roaches near food because they kill cockroaches when they eat them-not when they are squished.
  • Roach traps and baits work well to get rid of roaches if you live in a place where they are not an issue.
  • Never use boric acid as a horticultural dressing because it can be toxic to plants!

How to Kill Cockroaches

Use commercial pesticides that contain boric acid or diatomaceous earth as bait for roach traps and use them according to instructions. You can buy commercial pesticides at your local hardware store. Read the instructions on the label carefully. Keep in mind that: 

  • Killing roaches with a commercial pesticide like Raid® or boric acid does not kill the left-behind eggs. 
  • Once you have killed the adults and their babies, you will still see roaches for weeks! That is because cockroach eggs can stay in your home for up to two years without a female roach laying more until they are too weak to be produced.

Cockroaches can live for up to two years without food, but only one month without water. If a family member is not sick yet, they may be immune to the bacteria or virus that cockroaches carry.

The mother cockroach lays up to 50 eggs at a time and then dies. The cockroach babies are born without teeth or eyes! They are white and grow darker as they age.

The female cockroaches can live up to one year without needing to mate. However, all roaches eat dead things and rotten food, which is why you find them in your home looking for food.

Cockroaches jump up to 8 feet from a surface. However, the average distance is only about 3 feet. Yuck!

How to kill roaches using boric acid:

Boric acid is an odorless white powder that is made from boron with no chemical smell of its own. It’s not poison. It’s a pesticide. But it is safe to use around food because it does not stay on the surface where you put it, so when roaches eat it, they ingest it and die.

It does not work fast, though! You’ll need to place boric acid in small plastic containers where cockroaches will find them and begin eating them. You can purchase these containers at a hardware or home repair store or make your own from plastic film canisters. 

Boric Acid Roach Killer
Boric Acid Roach Killer

To make the bait: 

  • Mix one part of boric acid with three parts of sugar to make it more appealing for the roaches to eat. 
  • Replace the baits once every four days. 
  • Roaches need boric acid in their system for at least ten days, but it usually takes 35 to 45 days before they are ready to die.

This is a safe way to get rid of roaches in your house if you avoid using other chemicals and ensure that they do not come into contact with food or drink.

How To Kill Cockroaches Using Boric Acid?

Boric acid is the best form of roach killer because it is completely safe and effective against cockroaches. It works by interfering with how a cockroach’s nervous system regulates its body temperature, so it dies from overheating! It’s also nontoxic, which means it will not harm humans or animals. It is a perfect roach killer when you have children and pets around because it is so safe.

Boric acid is typically used as a pesticide because it has such a strong irritant effect that whatever animal eats, it will be sick and die. It also works by destroying the cockroach’s digestive system, making it very hard for them to eat any food they find. If you use boric acid to try and kill roaches, then you will want to follow these steps:

  • By looking for their droppings, you can ensure you know where all the cockroaches are hiding. This can help you determine what sort of bait attracts them most effectively.
  • Choose a roach bait that you want to use. Many types are available, but you will probably find the best results if you go with one that is pre-made so that all ingredients have been combined.
  • Find a place where you can put your bait without being in contact with pets or people who could eat it by accident. Try to choose something like a closet or under the sink where no one will come across it by accident.
  • Put out the bait and watch for them to eat it for about four days to ensure they are eating it regularly and not dying from ingesting the boric acid. Once you have established that the roaches are eating it, you will only need to change the bait once per month.
  • Make sure that your bait is wet enough that they can eat it and dry enough that they do not drown in either case.

How to kill roaches with borax?

Borax is a natural mineral, and it’s safe for humans, but roaches cannot tolerate it. Including borax in your bait mix will kill them, but they’ll die too fast for the eggs to be killed. So instead, you need to follow these steps:

Make homemade bait with borax; use sugar, water, or flour instead of peanut butter. Put out the bait where you see cockroaches.

You will need a lot of boric acids if you have major cockroach infestations. So you may have to put out a couple of bottles at once. You’ll need to use the boric acid in powder form and mix it with water to stay effective for long periods. 

How to kill cockroaches with diatomaceous earth?

diatomaceous earth insect killer

Diatomaceous earth (DE) is another natural insecticide that works by dehydrating the insect to death. A little bit of this will go a long way, so you’ll need to change the DE bait weekly. Here are some more tips:

  • It’s best to dust the whole room once and then replenish the feed bag as necessary, rather than spraying only a section of the room daily. 
  • Ensure you only allow your pets or children access to areas where you’ve treated them with DE. In addition, make sure that no one is allergic to it before trying it on an area like this.

Wood ashes work for controlling roaches, but if you want something milder, try using these tips: 

  • Dump wood ash on the area where you believe roaches are to be found. 
  • Sweep away the ashes and replace them as fast as you can. 
  • Put furniture or other objects between the roaches and the wood ashes.

Ashes are a powerful insecticide that will kill roaches, but you should try not to use them in areas where there is any chance of your family or pets coming in contact with them. As always, do not store ashes near any flammable materials!

How to Kill Roaches with Baking Soda?

Baking Soda

If you’re trying to get rid of roaches and want to know how to kill them, then you will want some baking soda. It’s straightforward to use and can be advertised by itself or in other homemade cockroach killer recipes:

Baking soda can be a powerful method of killing roaches, but you must ensure that you use it correctly for the best results. Baking soda is heavy and will fall to the bottom of cracks and crevices where roaches hide. However, if you spread baking soda in your cabinets and allow it to sit for long enough, it will kill off all the roaches hiding inside without fail. Here’s a guide on how to do this:

  • Spray the cabinet or area with spray or fogger using the product you feel comfortable using. This will help keep the area under control. 
  • Mix 1/2 cup of baking soda with 3/4 cup of warm water. 
  • Use a spray bottle full of this mixture to start filling any cracks and crevices you can find throughout the house. 
  • Spray the cracks and crevices liberally, then leave for 24 hours before removing all the baking soda from the inside. 
  • Removing this mixture from your cabinets will help eliminate any roaches hiding within.

Baking soda alone will not kill roaches in your home, but it will still help to control them and make them less noticeable when they’re around. You can use this with other homemade roach-killer recipes to help keep your home clean and sanitized.

How to Kill Roaches With Alcohol?

Alcohol is a great way to kill roaches because it dehydrates them and dries them out quickly. This makes alcohol an excellent choice for natural roach-killer recipes. Alcohol is also a great method of killing cockroaches in areas where using other insecticides would be dangerous due to children or pets playing in that area of the home. The following are additional ways you can use alcohol to kill roaches:

  • Mix 1/2 bowl of water with 2 cups of 99% isopropyl rubbing alcohol until no clumps remain. 
  • This can be used as a spray, but it is more effective when you leave the mixture in place, absorbing into cracks and crevices that roaches like to hide in. 
  • Leave it in place for as little as two days before removing it and replacing it with a new mixture.

Then spray or fog your entire home with the mixture you made earlier, then allow it to dry for a few hours before removing all the alcohol from within. The alcohol will kill roaches, which is why this method works so well.

  • Use 1 oz of 80-proof vodka or gin to kill roaches around your home. It’s very effective when used correctly and can help control an infestation without fail.
