Bugs compared to sharks

Which is more frightening?

Apparently the sharks were more ferocious and terrifying

But sharks are not common after all

And pests like mosquitoes

But it has been harassing our lives

Relevant data

According to the statistics of the World Health Organization, the number of deaths caused by mosquitoes in 1 day is more than the total number of deaths caused by sharks in 100 years (sharks in 100 years: 1035 people, mosquitoes in 1 day: 1470 people)!

Whether you live in a crowded and lively urban village

Still in a bright and spacious upscale neighborhood

Insect control is a compulsory subject

Today we are going to talk about how to control pests scientifically

1. Classification and identification of pests

The urban insect population is very large, and only some of them are harmful to human production and health. A journal of the Journal of Applied Entomology, Review and Prospect of Urban Entomology Research in China, divides the pests in urban insects into four categories: construction pests, sanitary pests, garden pests, and grain storage pests.

Construction pest

Refers to the pests that harm houses and buildings, mainly termites, followed by sky cows, long stupid, and pink stupid wood bees, which eat wood to destroy building structures.

Sanitary pests

Refers to all arthropods that directly or indirectly harm human health and affect people's normal life. For example, mosquitoes, flies, fleas, mites, cockroaches (cockroaches) and so on.

Garden pests

Refers to some insects that can parasitize or temporarily attach to plants for life and affect the normal growth and development of plants, such as thrips, mesozoans, mites, etc.

Food storage pests

Refers to insects that endanger stored grain and its products, as well as packaging, fixtures, warehouses, factory buildings and so on. There are more than 100 kinds of food storage pests that have been recorded, such as weevils, grain fools, and grain thieves.

Second, how pests affect our lives

From the beginning of human settlement, these pests have accompanied human life, and because of their different living habits, the harm to us is also different. A journal of the Agricultural Technical Service (Hazards and Control of Household Pests) summarizes the hazards of household pests:

1. Direct harm

Household pests can cause harm to the human body by biting and sucking, and some can also suck tissue fluid through parasitizing the human body and damaging human health. Surveys have shown that the mite infection rate in adults is very high, and it is also the culprit that causes allergic asthma, rhinitis, eczema and other pathological reactions. 80%-90% of asthma in newborns is caused by mites.

2. Spread diseases

Household pests can transmit diseases, including epidemics such as pathogens, plague, typhoid fever, malaria and other diseases. Taking cockroaches as an example, there are currently more than 40 kinds of pathogenic bacteria detected from cockroaches, cockroaches can mechanically carry these germs, just climb up from the sewer a minute ago, and may climb onto food and clothing in the blink of an eye. In addition, cockroaches also have the habit of eating and excreting at the same time. Exposure to or consumption of objects contaminated with cockroaches can lead to disease.

3. Other hazards

In addition to endangering our health, pests can also consume stored food, destroy furniture, buildings and books, and affect plant growth. Food loss due to pests in the United States is as high as $465 million a year.

Gained a general understanding of the classification and identification of pests

The harm of household pests is so much

How are we going to prevent it?

Guidelines for common household pest control

●Eight pest control guidelines●

1. Mosquitoes

A few months ago, Shenzhen issued a three-level warning of dengue incidence index, and the main culprit of dengue fever transmission is Aedes albopictus. Mosquitoes like to lay eggs in the water, removing the stagnant water is the most cost-effective measure to kill mosquitoes, pouring out a pot of water that may breed hundreds of mosquito larvae is much easier and more effective than chasing and killing hundreds of mosquitoes that are already able to fly, so as far as possible, turn over the pot and pour the tank to eliminate all forms of standing water. In addition, there are mosquito nets, mosquito repellent water, mosquito lamps, mosquito coils, insecticides and other mosquito repellent and mosquito repellent products to choose from.

2. Cockroaches

Cockroaches have a strong reproductive ability, even if they kill 90% of cockroaches, the remaining 10% of "survivors" can reproduce many offspring. It is not an exaggeration to name it the king of pests.

At present, the most effective way to remove cockroaches is to use cockroach glue bait, apply medicine in places such as stoves, cabinets, wall corners and other places where cockroaches often appear, after the cockroaches eat the rubber bait, the cockroach ingredients inside will not take effect immediately, and the cockroaches will be poisoned and killed after returning to the nest.

The poisoned cockroach will convulse and vomit excitedly after returning to the nest, and the cockroach has the habit of eating the feces, vomit and corpses of its companions, so that the toxic substance will spread rapidly throughout the cockroach nest.

Killing cockroaches is only the first step, you eat leftover snack crumbs, feed a nest of cockroaches in minutes, so do a good job of household hygiene and seal food is the cure for cockroaches.

3. Bed bugs

Bao, who has been bitten by bed bugs, is extremely itchy, hiding in various crevices and corners during the day and coming out at night to suck blood. If you wake up in the morning and find such a large red bag on your body, then you must be careful whether there are bed bugs sneaking in the house. There are many ways to kill bed bugs, from charcoal roasting (basking in the sun), white burning (soaking in boiling water), and chilling (freezing in the refrigerator). However, the most effective is to use agents such as permethrin and hypothion, and spray them on the surfaces and crevices of furniture such as bed boards and wardrobes according to the instructions for use. Drug treatment can not only kill once, because it is possible to kill the eggs of the undead, wait for about half a month, the small bed bug hatches out and then kills again, usually 2-3 times to completely clear.

4. Midge

Midges are commonly known as "small bites", with a body length of 1-4mm, and they like to be rotten, so there are especially many rivers, dams, and summer parks. If you don't want to be bitten by them, try to choose long-sleeved pants when you go out on an outing, and carry mosquito repellent with you to disperse them. Ordinary mosquito nets cannot stop midges from invading, and if you live on the first floor, use a thinner screen. Midges have limited flight capabilities, and if they find traces, they can eradicate possible dens nearby, such as filling potholes, removing stagnant water, blocking tree holes, and removing moss.

5. Ticks

Ticks, close relatives of spiders, like to stay in the grass and woods in the wild, with a small range of activities, and can only wait for prey to come to the door before waiting for the opportunity to act. Therefore, when going to the wild, pay special attention to the use of registered INSECT REPELLENT repellent products on exposed skin, if a tick is found to be attached to the body, it cannot be removed immediately, because ticks may contain infectious pathogens on the body, and after being stimulated, they will drill more and more into the body and release more tick saliva. Ticks can be applied with alcohol or ether to relax or die. Urban ticks are mainly transferred from pets to people, and it is necessary to always check whether the pet contains ticks.

6. Thrips

Thrips are a collective term for the insect class Taempera, which usually likes to attach to plants, has a certain phototropism, and prefers brightly colored clothes, especially green and yellow. Thrips are not harmful to the human body, if mistakenly into the eyes, it is recommended not to rub the eyes, wash off with water. The green plants on the balcony can be controlled by spraying soapy water and trimming brown "dumpling-shaped" galls.

7. Toxoplasma gondii

Toxoplasma gondii is not an insect and is an intracellular parasite. By parasitizing in cells, it travels with blood to all parts of the body and destroys human health. Many people believe that cats and dogs transmitted Toxoplasma gondii to humans, but in fact most of the toxoplasmosis infections are eaten. Toxoplasma gondii and eggs are afraid of high temperatures, whether vegetables or meat must be cooked to eat, there are cats in the home to regularly disinfect the cat toilet, to the owner to deworm.

8. Scrub worms

Scrubs are a type of mite that is less than 1 mm long. Don't look at this small cargo, being bitten by a chigger mite carrying a scrub pathogen, will infect with scrub worm disease, which in extreme cases may lead to meningitis and even death. Chigger mites like to live on mice, thus transmitting to humans, so if there are rats in the home, we must do a good job of disinfection and rat extermination. Bushes, grass, and river banks are also places they like to stay, and they should clean their bodies in time after going out to play. If a chigger mite is found to be attached, it can be picked with a needle.

There are many kinds of pests, but as long as we master their living habits and use scientific means and methods, we can still achieve the purpose of effective prevention and control
