If the bee is a honey plant, the bumblebee is useful as a pollinator of plants, then the wasp seems to be a completely useless insect that can only create a danger to humans. This is not exactly the case. - wasps also eat other insects, both pests and beneficial ones, for example, bees. Therefore, they have to deal with them often.
What is the danger?
The bite of a wasp is similar to a bee, but is accompanied significant burning sensation. This is a large red spot with a puncture site in the center. Often these bites are accompanied by extensive swelling and an allergic reaction of the body. 
It depends on the site of the bite and on the sensitivity of the human body to the poison of the insect. Wasp venom contains components that destroy cell walls and cause swelling and inflammation.
It also contains toxins that affect the nervous system. Therefore, the site of the bite hurts for a long time, heals slowly (as the cells recover) and itching very much.
Bites to the area are very dangerous for humans. neck, face, tongue, genitals. Swelling can cause choking or inability to urinate. Massive bites are a big danger.
They are characterized by the manifestation such symptoms: dizziness, heartache, confusion, a sharp decrease in blood pressure. In such cases, you must contact the medical institution for help. It should be noted that the allergic reaction of the body to wasp venom is the most dangerous. It may be accompanied by an increase in body temperature. 40 ° C, nausea, vomiting and in 10-15% of cases lead to death. You should not be sure of the absence of an allergic reaction, if once after a bite, everything turned out to be ok.
The body's sensitivity to poison can develop gradually and does not depend on the time between bites: everything is very individual. But if this happens, you must carefully consider the consequences.
Important! Wasps sting not only sting, but can bite and jaws. If the sting of a bee has a notch, and after a bite it dies, then the wasp does not have a notch, and it remains unharmed. But, unlike the bee, it does not pursue its victim.
These yellow-black arthropod insects sting only in self-defense. They show the greatest aggressiveness on hot days with a large accumulation of sweet fruits.
They are attracted not only by sweet smells, but also by perfumery aromas and bright colors of clothes.
Wasp control methods
The fight against these insects can serve a few reasons: a large hornet's nest in an undesirable place, an apiary, a large accumulation of insects that can sting or damage the crop. 
Before you get rid of wasps in the country, you must put on protective clothing, plan a plan of retreat, choose a means of destruction. You should be aware that insects are less aggressive in spring or at night.
It is not expedient to destroy the nest in late autumn, since insects will die from winter frosts, and the nest can be destroyed in winter without danger to health.
Chemicals
Chemical control agents are user friendly and effective. It is better to use a pesticide spray aerosol container in the evening, so that it will take effect at night. Spraying must be carried out throughout 10-15 seconds. 
How to get rid of the wasp nest in the country, if access to it is limited? In this case, it is better to use insecticidal dust. In the early morning, 40-50 ml of dust spray a hole in the nest.
Dust covers the legs and wings of the wasps, which penetrate into the center of the nest and pollute other individuals with it. After 1-2 days, the wasps die.
Insecticides that help to overcome insects in the garden: "Fitoverm", "Aktophyt", "Kinmiks", "Omayt", "Aktellik", "Inta-vir", "Aktara", "Karbofos".
Folk remedies
To combat the wasps, use a soap solution prepared from dishwashing liquid: 50 ml of the gel is dissolved in 1 liter of hot water. The solution is sprayed onto the nest for 10-15 seconds. 
The liquid settles on the wings of insects, preventing their movement. The process must be repeated several times so that each wasp is treated with soapy water.
A long hose vacuum cleaner can be used to combat insects. After catching, close the suction pipe so that the wasps do not fly out. If the buzz in the vacuum cleaner has stopped, then it can be open and clean.
You can fight in the open with smoke. To do this, you need to make a fire under the nest and smoke it for a hour in the wasp smoke from the nest. When the nest is empty, you must knock it down with a stick. 
How to deal with wasps in a wooden house? For this you can use water and a fabric bag with a cord. A bucket of water must be placed under the nest.
The bag must be quickly and carefully put on the socket and tightened with a cord. Next, quickly dip the bag with the nest into the water and leave it there until complete destruction.
Did you know? Wasps do not produce wax, so their nests look like paper. To build a nest, the insect scrapes wood from stumps, dry trunks, and even old wooden fences, leaving grooves on the surface. Mixing it with saliva, the wasp gets material for construction.
Use traps
The simplest way to catch wasps is a trap. It is effective when you can not find a nest: in apiaries, vineyards and gardens.
Before you fight the wasps in the country with this simple tool, you need to design it. For this fit a plastic bottle, wire or adhesive tape. Use a sharp knife to cut off the top third of the bottle.
Pour the bait into the lower part and close tightly with the cut part (neck in the middle). The design can be hung, if you make a wire handle. 
The principle of the bait is simple: the insect easily gets inside, but cannot get back. Attach the trap can also be with scotch tape.
It should be noted that the bait must be prepared so as not to attract bees. As bait use sour compote, kvass or beer. Sugar syrup will not work. The bait level should be below the inlet. If an insecticide is added to the bait, the captives will die quickly.
Effective number of baits - one approximately 100 square meters. The industry offers sticky tapes, but their use in the apiary brings little benefit.
Do wasps benefit?
The fight against wasps is pushing the question of the benefits they bring to the outside world. Their utility for the garden in pest control - they hunt caterpillars, leaf beetles, weevils, flies and other insects, feeding them their larvae.
By destroying pests, these insects increase yields and maintain ecosystem stability. In the food chain, they are an important link, since they themselves become food for many birds. 
They also take an active part in pollination. For example, wasp-blastophagous are the only insects pollinating figs.
The life cycles of this species fully correspond to the flowering cycles of the plant. Communication insect with a plant so strong that figs can not survive without a wasp and vice versa.
Did you know? The emerald cockroach wasp is capable of poisoning the cockroach's brain with a poison, after which it independently follows its mouth to become food for the future larva. The victim is 2-3 times larger than the aggressor.
First aid for bite
To minimize the effects of the bite, you need to suck out no later than 60 seconds from poison poison and apply cold - With this help it will be possible to narrow the vessels and reduce the spread of toxic substances into the blood.
Later, the affected area can be smeared with ointment, reducing capillary permeability and reducing skin-allergic reactions. Such remedies include "Fenistil-gel", ointment "Dermadrin", "Psilo-Balsam", ointment "Ketocin" and others. 
The effects of a bite can be of varying degrees of severity:
- light - The general condition of the body is normal, but redness, swelling and itching persist at the site of the bite. In this case, the place is treated with one of the antiallergic ointments, taking into account the peculiarities of use;
- average - edema has spread to nearby tissues, the place is painful, but there are no allergy symptoms. In this case, a cold compress can significantly ease the situation. Antiallergic ointments should be applied to the skin constantly until the tumor disappears. In case of severe pain, it is necessary to take painkillers and antihistamines in pills. A patient needs to take more fluids to quickly eliminate toxins;
- heavy - there are signs of an allergic reaction of the body. They manifest themselves in the following symptoms: fever, headache, shortness of breath, heart pain, rapid tumor growth and severe pain. Such an injured person needs qualified specialist help, but allergic reactions can develop so rapidly that failure to provide emergency help can lead to the death of the patient. You must give a pill any anti-allergic systemic agent. If unconsciousness and breathing is impaired, artificial respiration should be promptly carried out with an indirect heart massage. Delivery of the patient to a medical facility is mandatory.
Important! The consequences of the easiest bite of a wasp do not disappear before 1-2 days.
Fighting wasps is a dangerous undertaking. Perhaps you should not risk your health, but rather resort to the help of experts.
