"Hardcore Buyer" Since childhood, we have learned a common sense: except for humans themselves, all living things in this world have natural enemies. "Big fish eat small fish, small fish eat small shrimps, and small shrimps eat mud", forming an interlocking food chain. The existence of natural enemies prevents the number of every creature on the earth from being unbalanced. However, there is such a creature that not only everyone calls and fights, but there are countless natural enemies in nature, but it is still spread all over the world. It is the protagonist of our story today - the cockroach. You can also call it Comrade Xiaoqiang affectionately.
You may have some misunderstanding of the "weaker"
It can be said that any creature on the earth can beat it, and the scrap iron player is correct. Perhaps it is precisely because of the many natural enemies that cockroaches have evolved extremely powerful reproductive ability and vitality over the course of hundreds of millions of years of evolution. A mature female cockroach can produce an egg sheath containing 14-40 eggs every 7-10 days, which can reproduce nearly 10,000 offspring in a year, up to 100,000. Under extreme conditions, female cockroaches can also lay eggs.
In the absence of food, cockroaches can survive for a month, without water supply, and even after taking their heads, they can survive for nine days and continue laying eggs. Even when a nuclear war breaks out around the world, it is the only creature that can survive.
is too many to calculate because of its number. According to scientists' rough estimates, the number of cockroaches on the earth is now 70 trillion. So a joke circulating on the Internet: If you find a cockroach at home, it means there are 20,000 cockroaches lurking in your home!
Cockroaches can hide in very narrow gaps
Although it is a joke, it can also illustrate the rampant cockroaches in our family life. Cockroaches like humans so much, maybe it is because humans have killed all their natural enemies. There is only humans around them. But now people seem to be more afraid of cockroaches (laughs).
Back to the topic, cockroaches like to choose warm, humid, rich food and many gaps to live in places. All buildings where people live and live generally have these conditions, so cockroaches become pests that infringe on the sanitation of thousands of households.
I believe everyone is more clear about the harm of cockroaches. They will not only spread bacteria and viruses, but also pollute the environment. Home food, store goods, and factory products will also cause economic losses due to cockroaches.
Cockroach killing Unreliable folk remedies
And the history of the struggle between humans and cockroaches can definitely write a book. There are also many tips and folk remedies on the Internet, but in fact, many of them are not that magical, and most of them are not useful.
One of the unreliable methods: laundry detergent mixed with water or soapy water to mop the floor. It is said that the oil on the cockroach's belly will be broken down. In fact, cockroaches cannot be eliminated at all. Occasionally one died because the cockroach was drowned in the water. CCTV also conducted an experiment in person.
Unreliable Method Two: Onions to kill cockroaches. It is said that the smell of onions has a strong repelling effect on cockroaches, so just cut the onions into silk and put them in the kitchen or places where cockroaches often appear. Jiebing Insectics Division (a deworming team) once conducted an experiment. Onions only have a weak effect on cockroaches, but their effect is not obvious. Moreover, if the onion is left for a long time, it will rot and affect environmental sanitation.
Unreliable method: Orange peel kills cockroaches. It is said that putting dried oranges or lemon peels in a cabinet or food cabinet has a certain anti-roach effect. Jiebing also conducted an experiment, and the actual test results can be said to be quite speechless. Because there is no effect at all, cockroaches sometimes climb onto the orange peel and play, or even eat orange peel, but they are still jumping around. The three methods above
are the most popular folk remedies for killing cockroaches introduced online, but they are not useful in reality. We do not recommend that you try it here.
Reliable method to kill cockroaches
Although many methods are unreliable and cannot solve the problem of "I can't kill Xiaoqiang", after a long struggle, humans have summarized a set of "combination punches" to deal with Xiaoqiang.
The most test of psychological quality - biological treatment method .Cockroaches have many natural enemies and strong vitality in nature, so biological treatment is the most effective. So you can try raising spiders, scorpions, centipedes, etc.
is not a joke. Take the famous cockroach - the white-headed high-legged spider for example. There are many stores for sale on Taobao, and some of them have very good sales. However, most people will have physiological discomfort with spiders, such as polyps. For example, if you are interested, you can try it. A buyer commented that since he bought two and went home, he couldn't see the spiders he bought.
The simplest and most rude method - pesticide . This is an old method to kill cockroaches, which are usually used by many families. If you spray the medicine directly at home or aim it at the cockroaches, the cockroaches will escape everywhere, and some will die if they are poisoned too deeply. The advantage is that it takes effect quickly, and its disadvantages are very obvious. It is highly toxic and harmful to the human body. It is not recommended to use it in families with the elderly and children.
Emerging and fashionable cockroach killing method - cockroach killing rubber bait . This is a new environmentally friendly cockroach killing developed in recent years. It is made of various organic or inorganic glues as the substrate and adds active ingredients to kill cockroaches. The cockroach killing bait is a syringe-tube-type cockroach medicine . When used, just squeeze into the corners and gaps like an injection. Generally, it is better to squeeze one point between 10 to 15 cm. There are many advantages: it is harmless to both people and pets, and there is no odor during use; the medicine is paste-like, and will not evaporate, and the medicine is more lasting.
, but the disadvantages are also quite obvious. First, the price is relatively expensive, and second, it is not as good as the publicity effect. The cockroach killing rubber bait claims to be able to kill cockroaches chains, which means that cockroaches will dismember similar corpses by taking advantage of the habit of cockroaches. After eating poisoned companions, the toxicity will be transmitted to each other and finally destroyed. But it doesn't actually have that good effect, we will talk about it later.
Physical cockroach killing method— Cockroach House . The cockroach house uses bait to lure the cockroaches over, and then uses a sticking board to stick the cockroach's body and feet. The advantages are safety, easy to use and easy to clean. The disadvantage is that you must master the range of cockroaches and cannot eradicate them, and the speed of cockroaches is average.
Common cockroach medicines horizontal review
In addition to insecticides, cockroach baits and cockroach houses, some compound cockroach medicines have emerged on the market. So which of these many cockroach medicines is the best and most worth buying?
Southern Metropolis Daily made a horizontal review some time ago and purchased 8 common cockroach medicines on the market from e-commerce platforms, including bait, rubber bait, cockroach house, and aerosol. The prices range from 14.8-59.9 yuan. They were tested with about 160 cockroaches provided by Huashi Insect. They were observed and recorded for 5 consecutive days. The results showed that the most expensive cockroach medicine may not necessarily have the best effect.
Researchers from the Institute of Insects of South China Normal University divided about 160 large cockroaches into 8 feeding boxes containing egg shells. The researchers said that egg shells can not only serve as a shelter for cockroaches, increase activity space, but also serve as food for cockroaches. There are many small holes above the four walls of the feeding box, which can be ventilated and breathable. To prevent cockroaches from escaping, researchers applied Vaseline around the inner wall of the feeding box.
aerosol: immediate results, no living mouth.
Because aerosols take effect quickly, the glue bait, bait and cockroach house need to wait for a while before they can take effect, so the drug effect identification experiment is divided into two groups. First of all, there is aerosol. In such a narrow space, the aerosol has obvious effect. Five minutes later, cockroaches died in the "Radar" feeding box, while no cockroaches died in the "Lu Bailing" feeding box; 10 minutes later, half of cockroaches died in both boxes; 1 day later, Nandu reporters found that both groups of cockroaches died. But what is surprising is that the slightly cheaper radar is more effective.
Bait, rubber bait, cockroach house: The result is amazing
5 days later, statistics found that the effect of the two cockroach houses was relatively obvious, and about half of the cockroach houses were affected by food temptation the next day. In contrast, the effect of cockroach killing bait and rubber bait is less obvious. Among them, Shi Jie cockroach killing rubber bait is the most expensive sample, but the effect is not as good as expected. Judging from the chart, it is basically unproductive and there is no problem.
As for the reason for the lack of effect, researchers from the Institute of Insects of South China Normal University explained that it may be that other foods such as rat food and egg shells are more tempting to cockroaches and affect the efficacy of the medicine.
In addition, for the chain cockroach killing effect promoted by cockroach bait products, researchers also believe that it is unscientific. It can only be said that cockroach groups have eaten toxic bait and caused collective poisoning. Cockroaches will only eat similar corpses when food is scarce, but generally cockroaches at home will not have food shortage, especially when cockroaches at home are flooded to the point where you need to spend a lot of effort to kill them. This means that the environment is comfortable for cockroaches and sufficient food, so they will not eat their companions' bodies at this time.
According to the above horizontal review, we recommend that you use the combination method of aerosol + cockroach house. When cockroaches are rampant, or every once in a while, use aerosols to concentrate on the fight against cockroaches. In normal times, you can use the cockroach house to deal with the remnants.
The real cockroach killing requires a combination of prevention and treatment
In addition to killing cockroaches, to achieve real cockroach killing, it is still necessary to combine prevention and treatment to eliminate future troubles forever. Therefore, clean the house. Start with the kitchen. Wash the dishes immediately after meals and remove the food. Clean food debris and spilled liquid immediately and keep it basically clean. Pay special attention to cleaning the top of the stove, because cockroaches like grease.
seals holes and gaps in walls, damaged ceramic tile walls, floors, doors and windows, pipeline channels, etc.; seal the sewer entrance with a thin-eyed stainless steel metal mesh or install water storage bend pipes.
Finally, I wish you all to win this protracted battle with Comrade Xiaoqiang!
