Japanese experts share how to kill cockroaches and avoid this nasty animal

When the weather turns hot and humid, our homes form the perfect hiding places for cockroaches. After many cool months without cockroaches in the fall, winter and spring, cockroaches start to return in the summer and cause a lot of trouble for everyone.

You should not use a vacuum cleaner to kill cockroaches.

Most of us usually smack them with the first thing we find or use insecticidal spray. These are the most common methods.

But do these methods really work? According to Earth, the largest manufacturer of insect repellent products in Japan, some products work and some don't.

Some people are concerned about killing cockroaches with makeshift weapons such as fly swatters, slippers or rolled up newspaper because it can spread bacteria or scatter cockroach eggs. But according to the experts at Earth, as long as you don't touch the cockroaches with your bare hands, it's a good method to kill them.

Pay attention to kill cockroach eggs to avoid them multiplying in your home

Cockroaches that carry eggs in egg sacs are called ootheca . It is covered with a hard shell, so although the egg can fall out of the body, it is very difficult for the egg to be dispersed. Then you can clean the nest of cockroaches easily and no longer worry about cockroach eggs left in the house.

But since the cockroach eggs are contained in a protective bag, the insecticide will not be effective so the best way to dispose of the dead cockroach is to put it in a plastic bag and crush it and put it in the trash.

However, one thing is for sure, you should not use a vacuum cleaner to kill cockroaches. They may die in the machine, causing unsanitary and unpleasant odors.

In addition, even if the cockroach dies inside the machine, the eggs it carries can still live . The young cockroaches that hatch from the eggs will find their way out of the vacuum cleaner and then things will be even more disastrous.

In case of catching cockroaches alive, the best way is to use hot water or pour some shampoo on it . According to experts at Earth, cockroaches can be killed by water as hot as 60 degrees Celsius, so hot water is an effective weapon, but extreme care must be taken to avoid burns.

Bath soaps and body shampoos can also be effective solutions as they can clog cockroaches' pores or respiratory pores. These chemicals will basically suffocate the cockroaches. Such products also have surfactants in them that help remove the cockroach's protective waxy coating. That waxy coating repels water and other particles that settle on the cockroach's body, which is why it's so difficult to drown cockroaches.

But when the wax coating is destroyed by the surfactant, the shell is unable to repel pollutants, which blocks the spirochetes around the cockroach's body. So even if it works, it probably won't live long.

However, the nozzle of the shampoo and soap bottle is not convenient for aiming and spraying, so you can easily miss a cockroach, especially in case of panic when a cockroach suddenly appears. . The best option you can have while in the bathroom is a bathroom cleaner. It has the same function and also has surfactant, has a nozzle that is easy to aim and shoot.

After it dies, be careful when handling the cockroach carcass.

Now you know the best way to kill a cockroach but how do you get close enough and deal with the cockroach? Make sure to approach them from the front instead of behind.

Cockroaches have appendages at the back of their bodies called cercus that help them sense movement in the air. So they will run as soon as they sense you. However, cockroaches can't run backwards so you'll have a better chance of hitting them with the weapon in hand if you approach from the front.

Handling cockroaches after death also needs to be careful

After it dies, be careful when handling the cockroach carcass . One thing to remember is that even if it stops moving, it may not die. Cockroaches can also faint. Be sure to handle it with caution, or it will squirm as soon as you pick it up and in a panic you could throw it across the room. It's harmful, isn't it?

Equipping yourself with the things you need when facing a cockroach like gloves or something to cover your hands is a must.

The body of cockroaches can carry a lot of harmful disease-causing bacteria, and their feces and carcasses can also cause allergic reactions. Therefore , the use of gloves or hand coverings is essential.

If you don't want to touch it yourself, you can use tape to pick it up and throw it in a plastic bag without fearing its creepy legs or annoying jagged body.

Finally, you may see brown stains around the house, which are traces of cockroaches after death and are the droppings of cockroaches. Sometimes stains will be accompanied by 1-3mm black or brown streaks. This is cockroach droppings.

Of course, the best way to deal with cockroaches is to prevent them altogether. You can try natural methods like using mint, orange peel, lemon, onion, coffee grounds, baking soda, alum and the classic cockroach traps. Good luck.
