How to Safely Kill Cockroaches ?

Cockroaches are omnivorous insects with hundreds of millions of years of evolution. There is no doubt that they are hated by countless families in long history. They are highly productive, and carry a variety of bacteria and viruses. As they often invade homes, they can spread a variety of diseases through the harmful microbes they carry.

The Way Cockroaches Spread Disease

Cockroaches spread or help spread diseases in the following ways:
1. Excrements: Cockroaches’ unhygienic feeding habits make their bodies full of viruses and bacteria. They may also easily contaminate objects and spread a variety of harmful pathogens through their excrements.
2. Saliva: Similar to their excrements, saliva from cockroaches contains a variety of pathogens since cockroaches eat a great deal of contaminated food.
3. Direct contact: Cockroaches often live in sewers, cesspits, drains, garbage bins, etc. They come into contact with lots of bacteria and viruses there. So, anything that has been rubbed or touched by cockroaches can be contaminated.

In general, humans get diseases from cockroaches in a variety of ways. People are infected mainly by touching objects that had already been touched by cockroaches before.

Bacteria and Viruses Spread by Cockroaches

Cockroaches passively transport microorganisms, including dangerous pathogens, on the surface of their bodies. Cockroaches have been linked to the spread of 33 types of bacteria, including E.coli and Salmonella, as well as vibrio cholerae, leprosy, listeria and Typhoid. Among them, cockroaches are known to spread E.coli and salmonella. These viruses can cause food poisoning or gastroenteritis. It brings chest pain, stomach pain, diarrhea, nausea, vomiting, etc. In rare cases, these bacteria can spread into the bloodstream, causing life-threatening infections.


Cockroaches were first identified as the reason to cause rashes in the 1940s. Studies have found that cockroaches have protein allergens in their feces, excrements and surface of their bodies. People can easily develop allergies or asthma if the air they breathe has been contaminated with protein from cockroach excrements, vomit or skin that has fallen off. Asthma is a serious, even life-threatening, chronic respiratory disease. Asthma affects the daily life of more than 20 million Americans. According to a research, 20-60% of urban residents with asthma are sensitive to cockroach allergens. Asthma cannot be cured once and for all. Its symptoms can only be controlled with medication and environmental management of cockroach allergens.

Why are Cockroaches So Hard to Kill?

Cockroaches are arguably the most difficult of the common household pests to kill. Moreover, they are hard to kill for a number of reasons. Here are some facts we know about why cockroaches are so hard to kill:
1. Since cockroaches breathe through holes in their bodies, their heads are not necessary for breathing. It turns out that cockroaches can live for about a week without their heads. They do need them to feed, after all. The truth is that many cockroaches die from dehydration instead of the lack of food.
2. Cockroaches move so fast: Cockroaches can move at a speed up to 3 mph. In terms of body length, cockroaches can crawl about 50 times the length of their body per second. To do this, human need to run at a speed of 210 mph. They are quite sensitive to even the tiniest vibrations, which makes them difficult to be spotted. They can hide themselves in corners or crevices before they are approached and discovered.
3. Quick and frequent reproduction rate: Female cockroaches tend to have a lot of males around them. Therefore, cockroaches have a relatively higher reproduction rate. The truth than maybe shocking is that in the absence of males, female cockroaches can even reproduce through parthenogenesis. These factors can explain why cockroach infestations are so easy to occur.

Main ingredients of our products

Pyrethroids are biodegradable biosynthetic insecticides with low toxicity, high efficiency and a broad insect killing spectrum. It is the 4th generation of insecticide ingredients after organochlorine, organophosphorus and carbamate insecticides. The emerging of pyrethroids are caused by pyrethrins. Pyrethrins extracted from chrysanthemum are highly effective, low toxic and rapidly decomposable insecticide ingredients. Then, pyrethrins were discovered to have the disadvantage of being produced in very limited quantities and therefore expensive. Therefore, after World War II, scientists began to simulate pyrethrins and study how to synthesize them artificially. As a result, a variety of pyrethroids came to being. There are permethrin, bioallethrin, resmethrin, tetramethrin, phenothrin, permethrin, fenvalerate, etc. These ingredients have been shown to be more toxic to pests and less impact on humans and animals.

Imidacloprid is one of the most widely used insecticide ingredient in the world. It is a neonicotinoid ingredient that acts as a neurotoxin when it acts on pests. Its mode of action is similar to that of nicotine, a common ingredient in tobacco. The ingestion of imidacloprid causes the blockage of stimulation transmission in the insect’s nervous system. Such blockage will then lead to a build-up of acetylcholine in the insect. When acetylcholine builds up to a certain level, it will paralyze and kill the infected pests. Therefore, there is a lag in the effect of imidacloprid. Pests usually stop feeding within a few hours of the ingestion of this ingredient and die within 1-2 days.
