There are a lot of flies in summer, why does it always avoid the pursuit of fly swatters?

Because flies can see a lot of images every second, it's like slow motion, so they can naturally dodge.

Because flies have compound eyes, it can dynamically capture the movement trajectory of the fly swatter, and at the same time, the movement trajectory of the fly swatter is very slow in the eyes of the fly, and it can be completely avoided.

Because in their eyes, our behavior is like slowing down, and the movement is easy to dodge.

Because flies fly from back to front when they take off, plus the flies' flying skills are relatively high, and the flies' eyes have very good eyesight. And the fly also has 5 eyes, so the ability to distinguish is very good.

Mainly because the eyes of flies are very sensitive, and their nervous system is relatively developed, so they can quickly dodge every slap.

Because flies are very fast, and flies have compound eyes, this complex case allows them to dodge quickly.

Reason:

2. Flies like places with foul smell and fishy smell, and the sweat glands of the human body will secrete sweat, and the components of sweat are water, urea, and glucose, and flies are sensitive to sweat;

3. Flies have a sensitive sense of smell, and when humans exhale carbon dioxide and other odors, these smells will spread in the air and attract flies.

Prevention and control of the kitchen.

1. Prevention and control of flies in the collection and transportation of kitchen waste.

The accumulated food waste is rich in nutrients and sufficient water, which provides good environmental conditions for the growth of flies, so flies should be exterminated at the source. The garbage cans in the restaurant should be sealed with lids, and the garbage should be cleared every day, so as not to leave a chance for flies to lay eggs; Food waste trucks should be cleaned and disinfected regularly when they are hungry.

2. Prevention and control of flies in the process of kitchen waste treatment.

From the perspective of the influencing factors in the growth of flies, temperature and moisture have a great influence on flies. Therefore, in the process of kitchen waste treatment, the kitchen waste is cooked, and the temperature is kept at 45-50, which is conducive to the softening of the kitchen waste, and can cause the death of fly eggs, and will not cause the denaturation of protein intellect in the kitchen waste, and at the same time control the moisture content of the kitchen waste is below 40%, which can effectively control the birth of flies.

3. Environmental prevention and control.

Do a good job in the cleaning and sanitation of kitchen waste processing enterprises, and disinfect them regularly; Properly dispose of and remove residual garbage; Regularly inspect the equipment and feeding system to ensure that there is no water leakage and no spillage; Install window screens on the windows of the factory to prevent foreign flies from flying in; Do a good job in vegetation restoration, and at the same time plant some fly control plants are planted to effectively reduce the activity places of flies and inhibit the survival of flies.

4. The best time to kill flies.

Whether a fly can complete its life cycle or not is largely dependent on climatic conditions. When the temperature is lower than 15 or higher than 45 and the humidity is lower than 60% or higher than 80%, the growth of flies can be well inhibited. Of the total fly population, 80% are in the developing stage and only 20% are adults.

Therefore, the fly can be controlled in the larval stage by killing the fly in April.

It's hot, and that's when the flies are active, and the heavier the smell in summer, the more flies there are.

In the biological world, there are three types of natural enemies of flies: predatory, parasitic and microorganic, which can capture and inhibit flies. In the plant kingdom, nightshade, lavender, pitcher plant, seven mile, incarceiva fly plum and other plants have a special fragrance and smell, harmless to people, but have a certain control of flies and other pests, smell will be avoided, and also inhibit or kill bacteria and viruses.

1. What natural enemies are flies afraid of?

1. Predatory natural enemies: frogs, dragonflies, spiders, praying mantises, ants, lizards, geckos, insectivorous flies and birds, etc., chicken manure is a breeding organism of houseflies and flies, but there are always huge mites that will capture fly eggs and maggots in feces.

2. Parasitic natural enemies: such as bees, bees and other parasitic bees, often lay eggs in the body of fly maggots and pupa, and take fly maggots and fly pupae after hatching larvae. In the spring, the hemp fly pupae are attacked and killed by parasitic wasps.

3. Microbial natural enemies: Japanese scholars have found that Bacillus Morita can inhibit the occurrence of flies.

Second, what plants are flies afraid of?

1. Nightshade: also known as nightshade tree, produced in the American tropics. The heart-shaped shape of the leaves, the edges are covered with soft hairs, between summer and autumn, the yellow-green bell-shaped flowers bloom under the armpits of the leaves, and the finches in the treetops on the moon are full of fragrance, this fragrance is afraid of mosquitoes, and it is a good product to repel mosquitoes.

2. Lavender: blue-purple flowers, native to the Mediterranean, flower shape like wheat ears, usually blooming in June. Lavender itself has an insecticidal effect, and people make it into sachets and put them in the wardrobe, and some put them in the bedroom to repel mosquitoes.

3. Nepenthes: an insectivorous plant, a celebrity who repells mosquitoes.

4. Qilixiang: Qilixiang is a small evergreen shrub in all seasons, forming an umbrella house, with bright leaves, white and dense flowers, red fruits, touching the leaves to feel the rich sweetness, and the effect of repelling mosquitoes and feasting potatoes is good.

5. Cordyceps: Asteraceae herbaceous plants, small yellow flowers, a plant has hundreds of flower heads, there is mucus around each flower head, mosquitoes fall on it and stick, insect corpses are slowly digested as growth nutrients, dust falls on it, and there is no trace of digestion after a few days.

6. Fly chasing plum: the branches, leaves and flowers exude a sensitive smell of mosquitoes and flies, which has a strong mosquito repellent effect and is not harmful to the human body.

The flies at home are going to fry, where do so many flies come from?

Because this season is when its eggs develop small babies.

The best time to grow up and lay eggs with your baby.

So there will be more of them.

It's a fruit fly, and it's gone with a mosquito coil.

Fruit fly. <>

Introduction: Fruit fly or vinegar fly is widely found in temperate and tropical climate zones around the world, and because its staple food is rotten fruit, it can be seen in human habitats, such as gardens, vegetable markets and other areas. In addition to the Arctic and Antarctica, at least 1,000 fruit fly species have been found, most of which feed on decaying fruit or slippery objects, while a few feed only on fungi, sap or pollen.

Exterior features: small in size, 3 4mm in length. Identification of similar species is difficult, and the main feature is the presence of large red compound eyes.

The female is millimeter long, and the male is even smaller. Males have dark hind limbs, which can be used to distinguish them from females. Male and female identification methods:

Female flies are large in size and have pointed ends. Back: Annular 5-segmented, no dark spots.

Ventral surface: 7 abdominal segments. The first pair of asexual combs at the base of the tarsal joints.

Male Drosophila is small in size and has a blunt end. Dorsal Reading: Annular 7-segmented, continuing to the end with dark spots.

Ventral surface: 5 abdominal slices. The first pair of tarsal joints have a black bristle-like comb at the base.

Distribution: Living Environment:

Fruit flies are distributed all over the world, like humans, and spend the winter in human homes. Due to its small size, it is easy to pass through sand windows, so it is also common in the home environment. Some species live on rotten fruits.

Some species live in fungal or fleshy flowers. On the side of the garbage can or on the fruit that has been stored for a long time, as long as you find many small flies with red eyes, it is a fruit fly; Drosophila larvae are accustomed to breeding on garbage heaps or rotting fruits.
