It is challenging to eliminate cockroaches but not impossible. It will take some effort and time. But, soon you will get rid of these persistent nasty pests. Cockroaches love dirty, warm, and moist surroundings.

Your kitchen and bathroom are the main breeding points. So, keeping them both clean and clutter free is the key to the entire process. Below are a few tips to help you. The bonus is you will never have to touch the nasty bug.

Use Boric Acid

Boric acid is the most popular and effective method for eliminating cockroaches. It works effectively even for a massive nasty infestation. But, it is also not safe for humans and pets. To use Boric acid, remove things from the countertops, cabinets, and drawers.

The next step is to clean the surfaces with either vacuum. You can also use mild detergent and water for thorough cleaning. Then spread boric acid all over the place. Make sure you go behind the appliances and drains. It is better to apply it at night as cockroaches usually come out of their nest during the dark. For severe infestation, you will have to reapply it for two days or more. To make a Boric acid bait combine it with sugar and flour. 

Cockroach Spray

Imagine chilling in a lounge, and you saw a massive cockroach moving towards your couch. In this case, it is better to use cockroach spray. You can use a DIY cockroach killer or a chemical pesticide. Use the spray directly on the cockroach for at least 30 seconds. You can spray it from a distance targeting the bug. It will save you time and energy. And you will never have to come directly in contact with the cockroach. 

If you want to use cockroach killer spray for massive infestation, first clear out the place. Remove all the food containers, clothes, etc. Then after vacuuming, spray the killer on all the areas required. Remember to wear a mask while using chemical roach sprays. Also, disconnect your gas lines if using them in the kitchen. Cause most of these chemicals are flammable. It is also advised not to use harsh chemicals when you have children or pets.

Use Diatomaceous Earth

Diatomaceous Earth is one of the oldest and the most effective in killing cockroaches. It might appear as a fine powder to you. But they have a crystalline structure that can penetrate the insect’s skin. Diatomaceous Earth Powder cuts through the cockroach’s skin, causing water loss. So, it kills cockroaches through severe dehydration. 

It is safe for humans and pets as long as it is not inhaled. So, use a mask while dealing with it to protect your lungs. After cleaning the required area, spread the powder evenly. You might have to reapply and do it for a day or two for good results.

Place Adhesive Traps

Adhesive or glue traps are effective in removing a big cockroach. It is not the best option to use in a massive cockroach infestation. If you have a cockroach infestation use another method along with this. Adhesive traps work for almost all pests. Place them at the pest entrance and wait for them to come out.

You can purchase the Adhesive traps from the market or make one yourself. Take a large piece of duct tape and place peanut butter at the center. Place these traps where you suspect a cockroach hiding place. Check traps after 2 to 3 days. If it is full discard it and replace them with a new one. If it hasn’t caught any cockroaches on it, move it to another place.

Cockroach Gel

Cockroach gels are a strategic weapon against a massive cockroach infestation. It attracts roaches towards itself, making it their last meal. Cockroach gels are available in many different formulas. It lures the pest into eating the Gel Bait. Cockroaches mistake the gel for food and ingest the poison contained inside.

The best part is it spreads the poison from one cockroach to another. Cockroach feeds on their dead ones. So it will spread through their entire colony. It is a simple technique with quick results. The Gel Bait can also reach the area which is hardest to cover. That are cracks and holes in doors, windows, and walls. Just push a pea-sized amount through the syringe. You will see results within a day or two.

Spray Anti-Cockroach Concentrates

Anti-Cockroach liquid concentrates are available in the store. Dilute the liquid by adding water to it. Then spray it on all the places where cockroaches hide. It works best to kill cockroaches in crevices and cracks. You can also pour a few drops of this liquid into a large bucket of water and mop your house with it.

Bait Stations

When you have a severe cockroach infestation, it might be hard to find its source. In that case, cockroach bait stations are the most practical option. They work effectively on all types of cockroaches, big or small. The baits contain harsh chemicals that kill roaches after ingestion. Most of these premade baits have a compound that lures cockroaches toward them.

So, it usually takes 24 hours to get rid of the massive cockroach colony. When a cockroach finds something edible, it will carry it to its nest, killing itself and others. It is to use and makes no mess. Simply place them where you see cockroaches roaming. Use it under sinks, near drains, behind appliances, and in toilets. 

DIY Cockroach Killers

If you want to avoid using abrasive chemicals that are not pet or human-friendly, DIY baits are always an option. So, skip going to the store. And try making some on your own using things at home.

Fabric Softener 

Fabric softener kills cockroaches by suffocating them. The chemicals in this will block the pores on cockroach skin. Mix 90 ml of fabric softener with 60 ml of water. Then pour it into a spray bottle and shake it vigorously. Spray it where you know cockroaches are hiding. It works best when you spray it directly on the bug.

Soap And Water

It is an inexpensive method and kills cockroaches by suffocating them. Add three tablespoons of dish or any other liquid soap to a cup of water. Mix it well and pour it into a spray bottle. It also works best when you spray it directly on the cockroach. But it only takes 2 to 3 sprays to kill a cockroach with it.  

Baking Soda And Sugar Mixture

The food attracts cockroaches more than anything. Humans can ingest baking soda. But it is deadly for small animals. Eating baking soda will cause severe acidity in the cockroach, leading to a painful death. Take a large bowl and mix equal parts of baking soda and sugar. Place this anywhere you have seen cockroaches. It is also effective for severe cockroach infestation. 

Essential Oils

Essential oils like clove, rosemary, cedar, and eucalyptus have proven 100 percent mortality against cockroaches. Use Essential oil with a concentration between 2.5 to 30 percent. Take 100ml water and pour ten drops of the Essential oil in it. Mix it well in a spray bottle. Spray the solution where needed. This also deters other types of bugs.

What Naturally Kills A Cockroach?

The most effective natural cockroach killers are Borax and sugar and Diatomaceous Earth. Both of these kill cockroaches by causing severe body water loss leading to dehydration. Diatomaceous Earth is a white powder made from diatoms which are tiny organisms. It has fine crystalline particles that pierce through the outer skeleton of the cockroaches. 

Borax is a chemical that kills them by ingestion. You can use Borax Powder directly or combine it with other ingredients. Borax mixed with sugar lures the nasty bugs from all their hiding places.
