Does a cockroach bring a virus?
1, several methods of killing cockroaches
Nowadays, effective methods include putting out cockroach poison, erbium, spraying insecticide, smearing cockroach chalk, spreading powder and releasing insecticide and smoke. According to the actual situation, we choose to use it.
In addition to using the method of chemical drugs to kill insects, cockroaches can also be sticky boxes, bottles and other physical methods for trapping.
2. Cockroaches are the oldest insects
350 million years ago, cockroaches were active on the earth and were the oldest and thrive insect population in the world. Paleontologists have found 2 or 300 species of cockroach fossils in the Carboniferous strata. It's amazing that the cockroaches were the same things you saw in the kitchen today.
3. How many cockroaches are known in the world
In 1969, there were more than 4 thousand cockroaches in the world, and more than 5 thousand in 1982. There are 52 earliest records in our country, and now there are more than 200 kinds. But most cockroaches live in the wild, and there are only 10 kinds of species that are closely related to human beings.
4. Spread of diseases and carcinogens
Cockroaches carry at least 40 kinds of bacteria, nearly 10 kinds of viruses, 7 kinds of parasitic eggs and 12 kinds of fungi. According to the survey, the detection rate of Aspergillus flavus on cockroaches is 29-50%, which are teratogenic and carcinogenic substances.
5. The cockroach's star
A new compound, called hydrogenated juvenile hormone, has recently been approved to be put into the market in the United States. The test staff sprayed in a 100 unit apartment in Florida. The results showed that cockroach density decreased by 95% in 8 months, while in the enclosed kitchen, the killing rate reached 100%. The drug can deform the wings of the pests, behave abnormal, and eventually lose their reproductive capacity.
Do not eat, commit all sorts, everywhere there is
A cockroach crawl across the food will leave a disgusting smell. It often bites people's favorite clothes. Cockroaches bite and drill into their ears.
Cockroaches are omnivorous insects. The food that humans eat is love to eat; they also like books, leather, clothes, soap and so on; they often climb into the sewer, garbage dump and toilet to eat the excrement and the corrupted organic matter of dead animals. In almost all places where people live and live, there are traces of cockroaches.
A cockroach likes to breed under what conditions
There are at least four basic conditions for cockroaches to settle down in a place: warm climate, moist environment, abundant food source and multi gap structure. It is obvious that if these conditions are eliminated, the breeding of pests can be effectively prevented.
What is the egg sheath of a cockroach
After mating of male and female cockroaches, the tail end of a female cockroach grows out of a pod like thing called the egg sheath, and the egg is produced in it. A few females can produce more than 10, can produce more than 90 eggs sheath; an egg sheath, less can be hatched 10 only more than more than 50 small cockroaches can be hatched, the same kinds of cockroaches. So, it is important to eliminate cockroach ootheca, exterminate an ootheca is tantamount to destroying dozens of cockroach.
Where is the cockroach hidden in the daytime
Most of the day in the nocturnal cockroaches, drilling near water, food source, heat source near the walls, the furniture "seams, angle, heap" in hiding. We should pay attention to these cockroaches, where is the key of spraying, put the cockroach bait. The medicine is in place.
The cure for the eradication of cockroaches
Where environmental sanitation is dirty and messy, cockroaches are rampant. Therefore, to do a good job of health and control the environment is a cure. The health status will also have a direct impact on the effect of chemical control. Some people use chlorpyrifos to kill cockroaches and use them in a sanitary room. The insecticidal effect is 94%, and the insecticidal effect is only 75% in poor sanitary rooms.
Kill the cockroaches indoor first to improve health and eliminate cockroach habitat conditions, to carry out a wide range of plugging holes wiping joints and the "eight check" activities, remove the cockroach habitat and egg sheath, the trace of cockroach. The trace of cockroach refers to insects, residual limb, body, wings, molting, cockroach feces, empty egg sheath.
"Eight" means: check table, two chairs, three cabinets, check check check four port (sewer mouth) and five (sink), check the battery six case (food processing board), seven, eight (joint check check pile of coal pile, pile, pile of debris).
A cockroach with a hole in the hole
Cockroaches love hidden seam holes. The use of this pest living habits, can choose to use putty, cement or silica gel plugging block cracks and caves, allowing cockroaches to no place to hide. To eliminate cockroaches in the kitchen where the inner wall structure is badly damaged and the furniture is old, it is necessary to repair the house and renew the furniture.
How to kill cockroaches by spray
Cockroaches often drilled in the seam, the cave habitat to hide, so use the spray spray, needle, hole, must on the corner and around the spray, spray, spray, this effect is good, but also save drugs.
The cockroach is a reptile, the spray and the cockroach do not spray to the space, and do not have to face the mask, and all the walls are sprayed.
The trick on the cockroach bait
Put bait is commonly used as a simple method for killing cockroach, but the trick is to use properly, "less, many points, wide," is poison point more in the house, less dosage of each point, the distribution of a wide range. This cockroach habitat from crawling out to eat the bait, killing effect.
In order to prevent moisture bait failure, should be placed in a cloth cap on granular bait. Using a chalk with insecticide
