The official account of Foshan Center for Disease Control and Prevention
Recently released
Article on "Results of antimicrobial resistance experiments in Germany cockroaches".
It is noted
Germany cockroaches are resistant to two pesticides
According to the Foshan Center for Disease Control and Prevention, the Germany cockroach is a species of cockroach. The body length is about 10~15mm, the adult is brownish-yellow, has strong vitality, and can survive in extreme environments. Germany cockroach is a common and dominant species in Foshan, as a household hygiene pest closely related to human activities, it contaminates food, spreads diseases, and poses a serious threat to the health of the public.
At the end of September this year, the center carried out a drug resistance experiment of Germany cockroach based on the drug film method of the diagnostic dose method in the national cockroach resistance detection method Germany cockroach bioassay (GB/T26352-2010). The experimental results showed that Germany cockroaches were resistant to cypermethrin and permethrin insecticides, among which permethrin insecticides were highly resistant.
Experimental methods and results of antimicrobial resistance experiment in Germany cockroach
Netizens were amazed
"Cockroaches have evolved"
"Guangdong cockroaches are really powerful"
"Cockroaches have evolved"?
Foshan CDC responded
On October 12, the relevant media consulted the Foshan Center for Disease Control and Prevention as a citizen, and a staff member of the disinfection and vector biological control department said that the speculation that "cockroaches have evolved" is unscientific. According to the staff, the experiment uses a single ingredient of insecticides, rather than insecticides sold on the market, in fact, most of the common insecticides on the market are compounded, and the general ingredients are more complex.
It added that in fact, speculations such as "cockroaches are getting stronger and stronger" ridiculed by netizens are not scientific.
"The low resistance in the results of this experiment refers to the fact that cockroaches are resistant to cypermethrin insecticides, but not too strong, and there may be situations where cockroaches cannot be killed, and we can increase the dose appropriately when using them in life, and cockroaches have a highly resistant permethrin insecticide, we do not recommend everyone to use, although it cannot be said that it has no effect on killing cockroaches, but the effect is not as good as other insecticides." Said the staff.
The above-mentioned staff pointed out that the types of insecticides used in this resistance experiment are relatively small, and other insecticides such as carbicarb and imidacloprid have not been tested, so it is impossible to directly determine whether they are effective in eliminating cockroaches. However, experiments related to cockroach resistance have been done in various provinces and cities, and citizens can pay attention to the information released by the CDC in other regions or search for relevant papers on CNKI for reference and comparison.
Ingredients labeled on common pesticides on the market
"The two insecticide images in the tweet are not the brands of pesticides we recommend or recommend, we just want to show you that you can choose effective hygienic insecticide ingredients when choosing pesticides, as shown in the red box in the picture." Said the staff.
Want to stay away from cockroaches? These two methods are the most reliable
in everyday life
No one likes to see "Xiaoqiang"
Want to stay away from it
You can try to do this
Cockroach glue bait
Trapping with bait is an effective means of exterminating cockroaches. Its principle is to lure cockroaches to eat bait with insecticides, and the cockroaches will not die immediately after eating, and will only die of poison when they return to the nest, and cockroaches have the habit of eating companion feces, vomit and corpses, so that the toxic substances will "spread to mantises", and spread rapidly throughout the cockroach nest.
Studies have shown that cockroaches release pheromones that attract other people of their kind. So, cockroaches are all litters and litters. The corpses left behind by their companions can be made up of as a meal.
It is their gluttonous and social nature that they take advantage of. Moreover, the glue bait "kills cockroaches without hurting people" and is also safe for the human body.
Reliable glue bait has the effect of "group annihilation", but it needs to be used in the right way.
Remember one principle: small, much, comprehensive.
Cockroaches eat very little, and they can squeeze the size of mung beans when applying pesticides, without playing a long strip.
There should be more distribution points, and the application area should be wide, so that the chance of cockroach contact is large, about 50 centimeters a point.
Focus on dark corners and crevices in the kitchen, such as under the stove, around the cabinets, corner of the shelf, corner of the wall, refrigerator, etc.

Starve cockroaches
The most fundamental way to prevent cockroaches is to keep them clean and hygienic, so that cockroaches can't find food at home at all.
Cockroaches like to eat sweet, oily, fermented pasta-based foods, such as cakes and chocolate. If you want to get rid of cockroaches, you must seal what you can eat at home, and don't leave kitchen waste overnight.
In addition, cockroaches are resistant to hunger and thirst. In the absence of water, it does not live for more than 1 week. At night, it is best to wipe off the water stains on the stove before going to bed.
At last
To sum it up for everyone

4. The gap between the wall and the refrigerator and cabinet can be wiped with a rag dipped in water dripping with peppermint essential oil, cockroaches hate this smell.
Bedroom: wastebasket, under the bed board
Hair, dander and mites shed by humans or pets are also part of cockroach food.
Waste paper baskets, under bed boards, inside air conditioners, etc., should be cleaned and checked for cockroach feces. Cockroach medicine can be placed under the bed as a means of long-term control.
Toilets: near sewers
The humidity near the sewer is high, and there is a certain amount of dander, hair, dust, etc., which is the food source and hiding place of cockroaches.
1. Turn on the lights at night, cockroaches like dark and hate light;
2. Empty the used toilet paper in time;
